The top of this web page is the Illustrated Guide with photos of the motors and specifications to the right.

Sortable/Searchable Table

At the bottom of the page is a table that can be searched if you know you are looking for a certain type of motor (i.e. pod or saildrive), a certain power range, or for a specific weight/length of boat. If you are going to use the table, the page is best viewed on a computer rather than mobile or tablet.

Illustrated Guide

The motors are organized in alphabetical order by manufacturer, then by style of motor, i.e. fixed pod, steerable pod, saildrive and then by power of motor within those listing. For many styles there are multiple powers of motor available and where that is the case we have made it as easy as possible to line up the motor with its specifications. i.e. if there are three power of motor with different weights, it will be noted as kW: 2kw, 2kw, 3kw • Weight: 10kg, 12kg, 15kg. For some manufacturers the variations are more complicated and we have done our best to make it simple and understandable.

There is a lot of variety in the way manufacturers detail the technical attributes of their products. We have tried to take the most common measurements and assemble an ‘apples to apples’ comparison. See the notes below in ‘Measurements’

The photographs and drawings are from the manufacturers’ websites and are not shown in any consistent scale.

kW • Voltage • Current • HP: Not all manufacturers list all of these specifications. We have included the specifications available and where not available have used the notation N/A.

kW is the kW rating provided by the manufacturer. Most websites do not indicate whether it is input or output kW. When it is indicated, we took the output.

Voltage is most often referred on the sites as ‘Voltage’. Some indicate nominal or peak, we have used nominal and indicated if peak is also referenced.

Current Is noted when the manufacturer supplies the information. Generally it is measured in amperes: A. In some cases the manufacturer uses Amp Hours: Ah and we have noted it where that is used.

HP : is ‘HorsePower equivalent’ so that you can get an idea of the power of the motor in comparison to a HP rating you might be more familiar with. Where available, these measurements come from the manufacturer’s website, and different manufacturers measure the HP in different ways. Some even use metric horsepower, which is slightly different from imperial horsepower. Again, we have tried to make it as apples to apples as possible. (For general guidance, 1kW is round one and a third HP 1kW=1.3HP, or the reverse is that 1HP is around three quarters of a kW: 1 HP = .75kW).

Static Thrust. Torque, Efficiency: This is probably the specification that has the most variability. We have simply given whatever information the manufacturer has published on their website, when available.

Range and Running Time : We have not included estimates of range or running time because it depends on too many factors: battery size (sometimes type also), water conditions, speed, etc. The exceptions are for the ePropulsion and Torqeedo models which have batteries from the manufacturers specifically matched to the motors and therefore provide estimates on their websites.

General : If a manufacturer publishes a specification, we have tried to include it here, even tough other manufacturers may not include the same type of measurement.

»» Kräutler website

Kräutler is a long-established Austrian manufacturer of industrial electric motors. They began construction of electric boat motors in the 80’s mainly because they could not find a product that would live up to the standards of founder Oswald Kräutler. They make motors for industrial and ship use as well as recreational boats and probably offer the widest range of sailpods and saildrives on this page with everything from small .5kW steerable pods to electrically rotatable saildrives with power up to 30kW.

An explanation about the Kräutler section of this guide: The Kräutler fixed pods are available with AC motors (ACV) or DC motors (GPV). The AC are for smaller boats. They also come in two different configurations: fixed propeller and folding propeller. In the interests of making this page shorter, we have divided them in to the motor types for the written descriptions but have shown you the fixed and folding options in the images. In the table each of the motors has a separate listing. NOTE: The GPV motors are only suitable for short use in salt water.

Oceanvolt Servoprop Saildrive

The Oceanvolt ServoProp is a patented variable pitch sail drive that ‘combines a high efficiency sail drive with the most powerful hydro generator on the market’. Unique feature is the possibility to turn the propeller blades more than 180 degrees. The software controlled variable pitch sail drive adjusts the pitch of the propeller blades automatically so that the power generation and power output are optimal. The blades are designed to give the system maximum efficiency in forward, reverse and regeneration. With the blades set to the neutral sailing position, the propeller creates extremely low drag similar to the drag of a feathering propeller. ServoProp is capable of generating more than 1 kW at 7-8 knots & 3 kW at 11-12 knots.

The Pros, Cons, and Future of Electric Yachts and Sailboats

• By Sail Greener
• Last updated: April 27, 2022

Sail Greener is supported by our readers. When you buy through links on our site, we may earn an affiliate commission.

If you sail you likely spend considerable time—and money—cleaning, fixing, and worrying about your diesel or gas engine. When it comes to safety, your backup propulsion is as important as your sails. Can you rely on electric motors for safety? What are the pros and cons of buying an electric sailboat?   

Diesel engines are reliable, but they pollute. Diesel (and gas) engines emit greenhouse gasses and exhaust that includes particulate matter and carcinogens that are a risk to human health. 

Until recently, alternatives to marine diesel engines were limited. Boat owners could carry out their own repower projects or purchase expensive commercial electric motors. Storage capacity was a problem.

Fortunately, the winds are shifting and there are now numerous high quality and economically competitive alternatives to traditional marine engines. In this article we describe the pros and cons of purchasing a new motor or repowering an existing engine. We also describe the market for marine electric propulsion systems and identify leading boat builders, manufacturers, and installers.

Why do we need electric sailboats?

The climate is warming and we continue to pump greenhouse gasses into the atmosphere at a torrid pace. Transport emissions, including road, rail, air and marine transportation, account for nearly a quarter of global CO 2 emissions. 1 https://www.ipcc.ch/report/ar5/wg3/transport/ According to the United Nation’s International Maritime Organization , marine traffic accounts for nearly 3% of the world's CO ­­­ 2 emissions.

While emissions from recreational boaters are less than those from shipping and fishing fleets, they are still considerable. According to an estimate from electricmotoryachts.com , if just 5% of the roughly 13 million registered boats in the United States today repowered with electric, boaters would eliminate an estimated 1 billion pounds of CO 2 emissions. Scaled across boaters around the world, the potential for boaters to meaningfully reduce greenhouse gas emissions is significant.

Exposure to diesel emissions also poses health risks. The smallest particulate matter can contribute to heart attacks, strokes, and lung disease. High exposure to small particulates can impair brain development in children. The International Agency for Research on Cancer , part of the World Health Organization (WHO), classifies diesel engine exhaust as carcinogenic to humans.   

Is there a market for marine electric propulsion?

Global concern over climate is leading to a revolution in how we produce and use renewable energy. This is particularly true in the transportation sector. Sales of electric cars in 2019 increased 40%. In 2020, Tesla motors alone produced almost 500,000 new electric vehicles. This helped to propel Elon Musk to become the world’s wealthiest person. Electric vehicle penetration is still just about 3% but growing dramatically 2 https://www.mckinsey.com/industries/automotive-and-assembly/our-insights/mckinsey-electric-vehicle-index-europe-cushions-a-global-plunge-in-ev-sales# A key factor driving this growth, according to the European Patent Office (EPO) and the International Energy Agency, is innovation in rechargeable lithium-ion batteries and other storage technology. Batteries now account for nearly 90% of all patenting activity in the area of electricity storage. Between 2005 and 2018, patenting activity in batteries and related electricity storage technologies grew four times faster than the average of all technology fields. 3 https://www.iea.org/reports/innovation-in-batteries-and-electricity-storage

It is clear we are reaching a tipping point for electric automobiles and trucks 4 https://www.theguardian.com/environment/2021/jan/22/electric-vehicles-close-to-tipping-point-of-mass-adoption . Is the marine sector also experiencing an electric revolution?

The market for marine electric propulsion systems is lagging what is happening with cars and trucks. However, the potential for growth in this sector is extraordinary. In an article published in Yachting World, Christoph Ballin, CEO of electric motor manufacturer Torqueedo, estimated that only about 1.3% of marine propulsion systems are electric. 5 https://www.yachtingworld.com/features/future-yachting-smart-technology-126136 According to an article published in 2017 by IDTechEx there are over 100 manufacturers of electric boats and ships with an estimate of more than $20 billion in global sales by 2027 for non-military boats. According to the IDTechEx report, recreational boats are the largest—and fastest—growing electric marine market by sales.

The growth potential is enormous considering the size of the recreation economy. In the United States alone, in 2019 outdoor recreation generated US$ 788 billion dollars in output. 6 https://boatingindustry.com/news/2020/11/12/orr-provides-breakdown-of-latest-recreation-economy-data/  An estimated $37 billion of this came from retail sales of boats, engines, accessories and marine services. According to the U.S. Bureau of Economic Analysis (BEA) Outdoor Recreation Satellite Account (ORSA) data, Boating and fishing was the largest conventional activity for the nation as a whole, adding  US$ 23.6 billion to the economy. This was the largest conventional activity in 30 states and the District of Columbia and the second largest activity in 11 states. 7 https://boatingindustry.com/news/2020/11/12/orr-provides-breakdown-of-latest-recreation-economy-data/

Pros and Cons of Electric Motors for Boats

What are the pros and cons of electric motors for sailing?

Pros of electric propulsion

• Less noise : Electric motors are quieter than diesel engines and nearly vibration free.
• Lower long-term cost : Motors last a long time and require no fuel. You need batteries and electricity, but the sun and wind can recharge your batteries. You won't need to constantly change engine fluids, filters, or worry about leaks or old tanks.
• Cleaner and healthier: You won't end up with an oily mess in the engine room and bilge
• No emissions, no exhaust : Passengers and crew won't be exposed to hazardous fumes and particulates. You won't be spewing out carbon pollution.
• Instant power: Electric motors can go from zero to full torque instantaneously. Motors do not need to wait for engines to warm up.
• Weight and storage : Electric propulsion systems are typically less heavy than equivalent diesel systems. OceanPlanetEnergy.com estimates that electric propulsion systems are typically 1/3 the weight of diesel systems. This depends, however, on the weight of your battery bank.
• Easier maintenance and lower costs: Electric motors are simpler and easier to maintain than diesel generators. OceanPlanetEnergy.com estimates that maintenance costs could be 1/20 of the maintenance costs of a diesel engine in the first decade, even less over time because of electric propulsion systems use far fewer moving parts.
• Increased reliability and safety : Fewer moving parts translates into fewer breakdown which means which means more safety.
• Regeneration:   Batteries can be recharged while sailing using, solar, wind, and hydro generation systems.  For example, at sailing speeds over 6 knots Oceanvolt systems are reportedly able to generate significant power for recharging the battery bank.
• Improved maneuverability: Electric motors have high torque at low RPM, which can make maneuvering in tight spaces like marinas more precise. Electric motors can switch from forward to backward instantaneously.

Cons of electric propulsion

• Range anxiety: Depending on your battery bank and ability to recharge, you may have less range with an electric motor compared to a diesel engine.
• Cost: Electric motors can be expensive relative to combustion engines, but costs are plummeting.
• Lack of familiarity : Sailors familiar with traditional engines may not feel prepared or comfortable to switch to a new form of power.
• Fires: There can be a small risk of fires from batterie with improper maintenance, but this is also true with internal combustion engines.
• Charging time: Recharging batteries can take time, but charging times are changing quickly. Tesla V3 Superchargers support peak rates of up to 250kW per car, which translates to about 75 miles of charge in 5 minutes for a Model 3 and charge at rates of up to 1,000 miles per hour 8 https://www.tesla.com/blog/introducing-v3-supercharging . In January 2021 the Israeli company StoreDot announced new “exreme-fast-charging” lithium-ion batteries that could charge a car battery capable of 100 miles of charge in 5 minutes.   It will only be a matter of time before similar speed and capacity is available for boaters.

Industry Leaders

Who are industry leaders in the electric sailboat space?

Electric propulsion companies

Numerous companies produce electric and hybrid propulsion systems for the marine sector. Some of the best known and highest quality brands that provide electric propulsion systems for yachts and sailboats include:

• Elco Motor : Elco is one of the industry leaders in this field. The company has been around for more than 125 years and now produces a wide range of outboard and inboard electric and hybrid propulsion systems.

• Torqeedo : When Torqeedo was founded in 2004, concepts like “clean tech” and “electromobility” were just a glimmer in Mother Earth’s eye.  One of the pioneers in the modern marine electric propulsion sector, Torqeedo is now one of the market leaders. The company offers outboard and inboard electric motors and hybrid drive systems ranging from 0.5 km to 100 kw in addition to diverse accessories from lithium batteries and solar charging equipment to smartphone apps.
• Aquamot : This German company produces in-house electric propulsion systems for electric for boats and ships, including motors, batteries, and chargers.
• Kraeutler Elektromotoren produces a wide range of industrial, ship drive, and boat motors, including drive units for motor and sailing boats.

Electric sailboat manufacturers

Who builds sailboats with electric motors?

Electric propulsion is going mainstream. Dozens of boat builders are building electric-only boats (like SoelYachts.com and Silent-Yachts.com ). Some traditional yacht builders now offer electric propulsion options—and this will likely grow to include all major manufacturers in coming years. Examples of leading yacht manufacturers that include electric propulsion options include:   

• Arcona Yachts : A leading builder of high quality yachts from Sweden, Arcona is starting to offer high quality zero-emission models, such as the Arcona 415 .
• Alva Yachts : The German luxury electric yacht brand has designed both mult-hull (non-sail) and monohul (sail) boats. The company’s 25-m Ocean Sail 82 was designed with a hybrid propulsion system and a high capacity battery bank.
• Baltic Yachts : The Finish producer of luxury yachts and a world leaders in advanced composite yacht building in 2020 selected Oceanvolt for the company’s 68-foot Café Racer manufactured in Finland. The Javier Jaudenes designed boat is just over 20 meters long and 5.5 meters wide. 
• In 2001 Elan Yachts and Oceanvolt agreed to partner to build a full range of electric-powered yachts ranging from the luxurious GT6 to the the sporty E-Line performance cruisers.
• Hanse Yachts : The world’s third largest boat builder, Hanse produces the Hanse 315, which includes an electric rudder-drive option.
• Salona Yachts : A Croatian boatbuilder, Salona builds the Salona 46, a fast, comfortable, and luxurious electric yacht and winner of the Best Green Boat Award at the  Newport International Boat Show . 
• Sunreef Yachts Eco :   A manufacturer of luxury bespoke multihulls, Sunreef Yachts Eco catamarans are equipped with composite-integrated solar panel systems and lightweight batteries for energy efficiency and environmentally-conscious luxury cruising.
• Wally : The Dutch yacht builder produces, among its many other models, the 11.35 meter Wallynano MKII, which relies on an OceanVolt electric propulsion system
• Zen Yachts : A new company established in 2021, Zen builds what it claims is the world's first series production catamaran equipped with a wingsail.

Electric conversion companies

Who can help me convert my sailboat to electric propulsion?

A growing number of companies are dedicated to helping boat builders and individuals convert their yachts. These companies may provide design and support options for advanced battery systems, solar and wind systems, hydrogenation, and overall system design. Some of these companies produce their own electric motors and systems. Leading companies in the field include:

• OceanPlanet Energy : This company includes some of the giants of the industry. Bruce Schwab was the first American to officially finish the Vendee Globe. Nigel Calder is one of the best known sailing technology writers, including his must-read classic, Boatowner’s Mechanical and Electrical Manual. The company provides energy storage, charging, and monitoring systems; system design and consulting.
• Electric Yacht : The Minnesota, USA-based company with the eponymous name supports sailors interested in electric propulsion systems. The company helps boaters design and size system and provides motor kits, batteries, chargers, and other components. The company provides examples of conversion projects on its website.
• e Marine Systems specializes in distributing solar panels, wind generators, electric propulsion drives, inverters, and energy storage systems. The company is located in Fort Lauderdale, Florida, USA.
• Naval DC produces both “pure” solar and hybrid electric systems ranging from 10 kW to 1 MW. The company provides lithium battery solutions, data and monitoring systems, electric propulsion, and matched propeller systems.

Yacht dealers

A small but growing number of yacht dealers offer new and used electric boats. Green Yacht Sales is an example of a small company that supports the sale of electric yachts and systems from diverse manufacturers.

Global clearinghouses, like YachtWorld and Boat Trader , now provide options to filter searches for electric propulsion sailboats.

Battery technology and companies

Until recently, the amount of energy batteries could store was limited. The cost of buying a new battery bank was prohibitive for most sailors. Today, however, costs are dropping and batteries provide more charge. Range anxiety remains one of the biggest reasons sailors don’t want to swap out polluting diesel engines for quieter and cleaner all-electric systems. However, this concern will soon be obsolete.

There are many high quality marine battery suppliers. Some of the major players in the LiPO market include:

• ChargeEx Lithium Ion Batteries
• Dakota Lithium
• Dragonfly Energy
• Victron Energy

Successful Examples

Okay, this all sounds good in theory, but is it really possible to throw out your old engine and install a new motor? Here are a few examples of individuals and companies making the switch to electric yachts.

As with many disruptive technologies, it is easier for wealthy individuals to pay more—often much more—for tomorrow’s technology today. That said, these Super Early Adopters are a harbinger of things to come. These individuals may be risk takers but they are also typically really smart and forward-thinking.

Swedish billionaire Niklas Zennstrom is one example of a pioneering “mogul” in the electric yacht world. The founder of Skype and former Time Magazine 100 Most Influential People awardee, in 2018 Zennstrom’s team launched Rán VII. Yachtingworld described the boat as “…so angular it calls to mind Darth Vader or a Stealth bomber.”

Zennstrom shared his views on the future of electric racing in a CNN article in 2018:

“Having gone through the design, build and initial test cycle there is no doubt to me that the future for racing yachts is electric propulsion. It's lighter, less drag, quieter, and most importantly it is environmentally friendly.”

Do-it-yourselfers have been converting electric sailboats for years. The mainstream boating magazines and the media are increasingly showcasing the stories of these sailors retrofitting their boats. A few examples of well-publicized electric yacht conversion stories include:

• In 2019 Yachting World wrote an article, “How hybrid sailing yachts finally became a feasible option.”
• Dufour 382: According to an article in Yachting World , the owners Alcyone , a Dufour built in 2016, was retrofitted with an Oceanvolt SD15 saildrive moto r.

The future of electric sailboats

We are facing a climate emergency and the world is mobilizing to reduce emissions of greenhouse gasses. A growing number of boat builders, engine and battery producers, service companies, and individuals are addressing this need by building and retrofitting emission-free sailboats.  We are still in the early stages of this transformation, but change is coming quickly.

Some of the major challenges—and opportunities—for catalyzing this transition in coming years include:

• Battery storage, charging, and cost: The pace of technology change in the battery sector is dizzying. The amount of charge, the time to charge, and the price per kilowatt of battery storage systems are all improving.  Superchargers are already widespread on land. How long will it take for marine supercharging stations to fill the world’s marinas?
• Overcoming tradition : Sailors who have used the same technology for decades may hesitate to switch to new technology. Sailors used to heavy yachts and small batteries may look with skepticism on this new technology. Range anxiety is very real in the middle of the ocean. 
• Cost : As with any new technology, early adopters may have to pay more. The cost of electric propulsion, solar and wind power, and battery storage are dropping quickly. Cost will soon be less of a concern and may become a clear benefit.
• Retrofits: Many boats still sailing form 1960s and 1970s so 50 years of old boats locked in. But this is also an opportunity for individuals and companies who are willing and able to take this space
• Manufacturing: making boats expensive and companies may not want to take risks. But new companies are emerging, and the major yacht companies now coming out with electric options (examples).

We are at the dawn of a new age of sailing. With each passing month electric propulsion technology is improving. Motors are getting better, batteries and solar panels are getting cheaper, and electric sailboats are starting to become mainstream.

What’s the biggest advantage of the Power Rudder? Maneuverability. You’re now directing the thrust as you turn the wheel, giving you the ability to put the boat wherever you want it. In a tight spot? No problem. All of our boats can turn within their own radius (check out the video below).

The Power Rudder has been standard on all new Duffy Boats since 2008 and has changed the entire Duffy “experience” for the better. No more straight shafts indirectly connected to the motor through belts and pulleys. No more turnbuckles requiring adjustment if your motor becomes slightly misaligned causing noises and vibrations. This has given us the ability to redesign all of our models and completely get rid of the bulky center helm, resulting in an amazing amount of interior space opening up thanks to the steering and helm being shifted over to the starboard side. Learn more about Duffy boats here.

   Here are a few more advantages gained from the Duffy Power Rudder:

• – 100% Steering Authority in Reverse
• – 35% More Efficient Thrust
• – Superior Maneuverability (boat turns within its own length)
• – Also includes our  Patented 4-Blade Weedless Propeller
• – Whisper Quiet Operation
• – Compact Design Creates Luxurious Interior Space (under aft seat, completely out of the way)
• – Trusted Duffy Reliability: Over 10 years of development and 10 years now in operation as a standard feature on our boats.
• – No Belts!  No turnbuckles to adjust.  Ever.

Electric boat propulsion drives – new gear for 2022

• January 20, 2022

Six of the latest electric boat propulsion drives and outboards new for 2022, as released at the METS trade show.

New for 2022 from METS trade show – Electric boat propulsion drives and electric outboards

Bluenav bluespin retractable turbine electric boat propulsion.

BlueSpin Retractable is a hybridisation solution for motorboats with outboards. Switching between propulsion modes is done at the push of a button. It works in a similar way to a hybrid car, where you can have a combustion engine on for high speed and longer cruising but when you’re slowly ticking away through moorings or up a quiet creek, you can switch over to e-drive mode and quietly whisper along with just the electric boat propulsion and a smug grin.

BlueSpin is vertically retractable and rotating so you can also use these for sideways maneuvers and they tuck away neatly when not in use so there’s no drag.

BlueSpin Inhull motor

There’s an in-hull version of this retractable e-drive too, though we have yet to see how this would work in practice with real world conditions that include weed and plastic bags and all manner of in-water rubbish that could block the retracting leg, it’s a step in a very interesting direction for those of us who are keen to move on from diesel engines in our sailing boats. This can be retrofitted to older vessels and specified from new for new builds. The directional prop would be a really interesting function to have, especially for yachts with single prop and twin rudders.

• Reduced noise, air and water pollution
• Ease of maneuvering at low speed
• Low maintenance cost
• Can be used for hydrogeneration
• Thrust rotation or selectable orientation
• Retractable option to limit drag impact
• Available in several power outputs (15, 20, 30 et 50kW)

Price: TBC Read more about the BlueNav retractable drive at Bluenav.fr

Molabo electric drive motor

Weighing just 45 kg (including motor and controller) this  48v drive can put out a constant 50kw of drive thrust. Because it has touch safe voltage and uses low-voltage components it is less expensive than higher voltage alternatives and it’s lower weight enables it to consume less energy. Therefore, because of the low voltage drive design, you won’t need high voltage training to install the unit. Molabo stateds that this shaft drive has system efficiency of more than 95 % at the optimum operating point, this is the combined efficiency of the e-motor (97 %) and controller (98 %). The stator cage gives a reassuring robust look to the unit too.

We are likely to see more and more people swapping their old smoky or dead diesel engines out for these electric boat propulsion units. We’re looking forward to seeing a working model fitted and tested out on the water later this year.

E-propulsion Evo series of three new motors

Buy EPropulsion from Nestaway or any dealer listed on the Epropulsion dealer page.

Remigo electric outboard motor

The Remigo fully integrated 1000w electric outboard motor is a first of its kind. Designed to be simple to use, mount and adapt to multiple small boats or tenders.

The mounting bracket moves on the body to allow up to 80mm of leg adjustment. Portable and stowable,  it could easily slip into the lazarette or a small hatchback car.

They say that it can be charged with AC or DC, with a fast AC charge taking just 3 hours and a DC full charge taking around 12 hours.

In eco mode, travelling at 2 knots, you’ll get up to 30nm out of it. If you travel on a fast tidal river needing to motor at 5 knots, then you’ll get just under 5nm from one charge.

• Understanding boat rudders: Navigating the key component for smooth sailing

Navigating a boat requires a complex interplay of various components, and one of the most crucial elements is the rudder. In this comprehensive guide, we will delve into the world of boat rudders, exploring their functionality, importance, and role in steering a ship to smooth sailing.

What are boat rudders?

Boat rudders are an essential component of the vessel's steering system. They are hydrofoil-like structures located at the stern (rear) of the boat, underwater. The primary function of the rudder is to control the direction of the boat by redirecting the flow of water as the boat moves forward.

The role of boat rudders in steering

Boat rudders play a vital role in steering a ship. When the helmsman turns the wheel or tiller, the rudder changes its angle, redirecting the water flow on one side of the boat, creating more resistance on that side, and causing the boat to turn in the opposite direction.

Types of boat rudders 

Spade rudders: Spade rudders are simple and streamlined rudders attached directly to the hull. They are commonly found in modern sailboats and provide excellent maneuverability and responsiveness.

Skeg rudders: Skeg rudders are partially submerged and supported by a skeg, a vertical extension of the hull. These rudders offer increased protection and are often used in larger motorboats and trawlers.

Balanced rudders: Balanced rudders have a portion of the rudder forward of the pivot point, which balances the force applied by the helmsman. This design reduces the effort required to steer the boat.

Barn door rudders: Barn door rudders are large, flat, and wide rudders resembling barn doors. They are commonly seen in traditional fishing vessels and provide excellent control in rough seas.

Spade hung rudders: Spade hung rudders are free-floating rudders attached to the boat only at the top, allowing them to swing freely. They are commonly used in high-performance sailing yachts.

Components and mechanics of boat rudders

A typical boat rudder consists of several key components:

Rudder blade: The rudder blade is the flat, vertical surface responsible for redirecting the water flow. It is the most critical part of the rudder and comes in various shapes and sizes.

Rudder stock: The rudder stock is a sturdy vertical shaft that connects the rudder blade to the steering mechanism. It provides the necessary support and stability for the rudder.

Tiller or wheel: The tiller or wheel is the steering control operated by the helmsman. When turned, it causes the rudder to change its angle and steer the boat.

Rudder bearings: Rudder bearings are the mechanisms that allow the rudder to pivot smoothly on the rudder stock. Properly lubricated and maintained bearings ensure easy steering.

Steering linkage: The steering linkage consists of rods or cables connecting the tiller or wheel to the rudder stock. It transmits the helmsman's steering inputs to the rudder.

Steering a ship: The interaction between rudder and helm

The process of steering a ship involves a coordinated effort between the rudder and the helm. When the helmsman turns the wheel or tiller, the rudder angle changes, causing a difference in water flow on either side of the boat. This creates a force imbalance, turning the boat in the desired direction.

The effectiveness of the steering system depends on various factors, such as the rudder's size, shape, and angle, the vessel's speed, and the water conditions. Proper coordination between the helmsman and the rudder is essential for precise maneuvering.

Maintaining and repairing boat rudders

Regular maintenance is crucial to ensure the optimal performance and longevity of boat rudders. Here are some maintenance tips:

Inspect for damage: Regularly inspect the rudder blade, stock, and bearings for any signs of wear, damage, or corrosion.

Lubrication: Ensure the rudder bearings are well-lubricated to prevent friction and allow smooth movement.

Antifouling: Apply antifouling paint to the rudder to prevent marine growth, which can negatively impact performance.

Check steering linkage: Inspect and adjust the steering linkage regularly to maintain precise control.

Address issues promptly: If any problems or abnormalities are detected, address them promptly to prevent further damage.

Rudder design innovations

Advancements in technology have led to innovative rudder designs aimed at improving performance and efficiency. Some notable innovations include:

Hydrodynamic profiles: Rudder blades are now designed with advanced hydrodynamic profiles to reduce drag and enhance maneuverability.

Rudder fins: Some rudders are equipped with additional fins or foils to improve stability and minimize yawing motion.

Retractable rudders: Certain sailboats feature retractable rudders, which can be raised when sailing in shallow waters, reducing the risk of grounding.

Steer-by-wire systems: Modern vessels are adopting steer-by-wire systems, replacing traditional mechanical linkages with electronic controls for smoother steering.

The influence of rudder size and shape on turning radius

The size and shape of the rudder directly impact the vessel's turning radius. Larger rudders with greater surface area provide more steering force and can turn the boat more quickly. However, larger rudders also create more drag, which can affect overall speed and fuel efficiency. The optimal rudder size depends on the boat's size, weight, and intended use.

Rudder efficiency and hydrodynamics

The hydrodynamics of the rudder significantly affect its efficiency. Smooth and streamlined rudder designs minimize drag and turbulence, resulting in improved performance and fuel economy. Advanced hydrodynamic analysis and simulation tools help optimize rudder shapes for various vessels and operating conditions.

Common rudder issues and troubleshooting

Like any mechanical component, boat rudders can experience issues over time. Some common problems and troubleshooting tips include:

Stiff steering: If the steering feels stiff or unresponsive, check for obstructions in the rudder bearings or linkage.

Vibrations: Vibrations during steering may indicate misaligned rudder blades or bent rudder stocks.

Leaking bearings: Leaking rudder bearings require immediate attention to prevent water ingress and corrosion.

Excessive play: Excessive play in the rudder could be due to worn steering linkage or loose connections.

Reduced maneuverability: Reduced maneuverability may result from a fouled or damaged rudder blade.

Rudder steering systems

Various steering systems are employed in conjunction with rudders, each offering unique advantages:

Tiller steering: Common in smaller boats, tiller steering directly connects the tiller to the rudder stock, providing direct and responsive control.

Wheel steering: Larger boats often use wheel steering, which utilizes a mechanical or hydraulic system to transfer steering inputs to the rudder.

Hydraulic steering: Hydraulic steering systems offer smooth and effortless steering, ideal for larger vessels.

Electric steering: Electric steering systems, also known as electro-hydraulic steering or electronic power steering (EPS), utilize electric motors to assist in steering the boat. These systems work in conjunction with hydraulic components, making steering more effortless and responsive for the boat operator.

FAQs about rudders

4 Rudder Types for Sailboats

Last Updated by

Daniel Wade

June 15, 2022

A rudder is an ancient piece of technology that people still use to steer sailboats today. Modern sailboats use many different types of rudders.

If you turn the rudder to the left, the stern will turn right, and vice versa. You can use either a steering wheel or a tiller to move the rudder. Not every type of boat has the same kind of rudder, nor should every boat - different boats need significantly different rudders.

There are several different types of rudders in common use. Sailboats use full keel rudders, spade rudders, outboard rudders, and skeg-mounted rudders, plus variations on each type. What type of rudder is best depends on the shape of the hull and the boat's size.

Table of contents

Different rudder types and their advantages

Full keel rudders.

Many sailboats have a full keel rather than a fin keel, which requires a particular type of rudder. A full keel is the standard type of keel, or flat blade at the bottom of a sailboat. A full keel is designed for stability, not speed - it can keep you safe in rough water.

A generation or two ago, nearly all cruising boats had full keels. However, this is no longer true. Many customers today prefer fin keels, which are designed with speed rather than stability in mind.

A fin keel is smaller than a full keel and shaped differently. Fin keels are more popular today because many sailors today never go far from the coast. If you are near the coast, fin keels are relatively safe.

With a full keel sailboat , the rudder appears to be part of the keel. It is attached with a hinge and looks like a continuation of the keel. There may be a hole between the keel and the rudder, where the propeller is, although not all boats use this design.

What is the advantage of a full keel rudder?

A full keel rudder is strong and protects the boat from harm. A full keel rudder helps a boat survive a storm. Any debris floating by will not snag on a full keel rudder as it will snag on some other rudders.

Do full keel rudders have any disadvantages?

It is harder to move a full rudder than to move other types of rudders. Water flowing by the boat puts a great deal of pressure on a full keel rudder and makes the rudder hard to move. It takes a lot of force to push the rudder against the water moving past the boat.

Spade rudders

Spade rudders are for fin keel boats rather than full keel boats. A spade rudder sticks straight down into the water. A spade rudder can rotate left or right with a rudder post that extends into the hull.

Advantages and disadvantages of spade rudders

The most obvious advantage of the spade rudder is that it can be part of a fin keel boat. A full keel rudder requires a full keel - you could not attach a rudder of this type to another type of boat.

It is also not nearly as difficult to turn a spade rudder as it is to turn a full keel rudder. The water does not put all of its force on one side of the rudder, so it does not take as much force to turn it.

One disadvantage is that debris floating in the water can get caught on a spade rudder. Spade rudders are more delicate than full keel rudders in many ways. Debris can damage a spade rudder.

A spade rudder can also be damaged by rough water. Large waves may exert enough pressure on a spade rudder that it will break. A large wave can bend the rudder post, and after that happens, your rudder becomes useless.

Outboard rudders

An outboard rudder is not part of the boat's hull and is mounted outside of it, at the back of the boat. Usually, an outboard rudder is not hooked up to a steering wheel.

Instead, it is hooked up to a tiller, which is a steering lever. A tiller can take a bit of getting used to if you are used to a steering wheel, but a tiller is not hard to use. Many sailors prefer a tiller, especially for smaller boats.

Advantages and disadvantages of outboard rudders

If an outboard rudder is damaged, it is not likely to damage the rest of the boat. Since there is no rudder post running through the hull, damage to the rudder usually won't mean damage to anything else as well.

You may also be able to remove and fix a damaged outboard rudder while you are still out at sea. There is no way to remove a rudder that is part of the hull and beneath the boat, but a rudder attached to the boat with hinges may be possible to fix at sea.

Outboard rudders are not necessarily weaker than and can be stronger than other types of rudders. The hinges that hold an outboard rudder in place may be stronger than a rudder post.

In some ways, an outboard rudder is worse than either a spade rudder or a full keel rudder. Unlike a full keel rudder, things like rope floating in the water can get caught on an outboard rudder. Objects floating by can also hit and damage an outboard rudder more easily than they can damage a more durable full keel rudder.

Compared to a spade rudder, the outboard rudder is harder to turn. The water pressure will always be on one side of the rudder; this is not always the case with spade rudders.

Skeg mounted rudders

Skeg rudders are both durable and possible to use on fin keel rather than full keel boats. Skeg mounted rudders are more durable than the spade rudders you usually find on fin keel boats.

Skeg mounted rudders have the same disadvantage as full keel rudders and outboard rudders, which is that they require more energy to turn. The water will put all of its pressure on one side of the rudder. Only spade rudders avoid this problem.

Is a tiller better than a wheel?

Either for inexperienced or veteran sailors, a tiller can work better. With a tiller, you will get immediate feedback. If you turn a wheel, the boat won't turn right away, which can confuse or annoy a new sailor.

The tiller should be long enough, as it is harder to turn if it is shorter. In strong winds, you need a long lever to turn your boat without it taking a great deal of strength.

It is easier to turn a wheel than to turn a tiller, as there is more leverage with a steering wheel. Therefore, wheels are better for larger boats; as a tiller is harder to turn with a bigger boat.

A tiller's advantage is that it is more responsive than a wheel, even though it is harder to turn. The boat will start to change direction almost immediately if you use a tiller. In racing, it is normal to use a tiller because you can change direction more quickly.

How does a rudder work?

A rudder works through water pressure. If you turn the rudder, the pressure becomes higher on one side of the rudder than the other. The rudder then moves toward the side with the lower pressure, which causes the boat to change direction.

When a sailboat turns, it pivots around a point near the middle of the boat. Both the stern and the bow move simultaneously, with the middle of the boat not moving. You have to take this into account while sailing, or else you might swing the end of your ship into another boat.

What is the purpose of the keel?

The keel keeps the boat stable. Without a keel sticking down from the boat into the water, it would be easy for the wind to push the boat around. Without a keel, the wind could easily push you sideways and make the ship much harder to control.

A keel is also weighted. The keel is full of ballast, which is weight that keeps the boat from flipping over. Without ballast, a boat would be top-heavy and unsafe.

Keels are usually made out of the same material as the rest of the boat - if the boat is aluminum, the keel will be as well. The ballast is usually lead.

While full keels are better in rough weather in most ways, a fin keel does a better job of preventing the wind from blowing your boat around. Wind can create leeway, which is sideways movement of the boat. Leeway is most likely if you are sailing into the wind.

Do rudders often fail at sea?

Yes, a rudder failure is one of the more common hazards you might encounter at sea. Not every sailboat has a good, durable rudder. The rudders on cheap boats, especially cheap fiberglass boats, can fail.

The rudder pole should neither be too weak nor too strong. If the rudder pole is too weak, it will bend easily. If it is too strong, it may damage the hull rather than bend, which is even more dangerous.

A rudder has a metal framework inside of it. If the framework breaks, the rudder will become unusable. With a cheaper boat, the metal framework may not be welded together properly.

Make sure you buy a sailboat that has a reputation for safety. Don't buy the cheapest boat you can find - look into whether or not the boat is safe to take out to sea.

Using a trolling motor on small boat

• Thread starter PK Harvey
• Start date Apr 28, 2021
• Forums for All Owners
• Trailer Sailors

Hi, all. After years of sailing medium-sized Hunters (sold my last of those after a move a few years ago), I'm starting in with a Classic Lido 14, as a boat I can trailer and use to teach my grandsons to handle a sail. I'll be taking the boat out on Lake Buchanan in the Texas hills. There aren't any good choices for a permanent slip for a little boat like this, so I'm going to be launching her new each time out. Here's the issue: The ramp near my property on the lake has an available dock for loading, etc., but it's in close enough quarters that it's not an option to move from the trailer to the ramp under sail. I'd like to add a small electric trolling motor just to move the boat around in the inlet where we'll be launching. I've read some advice that a small gas outboard is a better choice, but in Texas that means registering and all the paperwork for being a power boat. My plan would be to just use the trolling motor to move the boat the 50 or so feet to the dock, and then offload it before I head out on the lake. Wondering how much thrust I'd need on a trolling motor to move a roughly 350 lb. (fully rigged) boat around in those limited circumstances. Thoughts? Thanks in advance for any help.-PK

I am sure a trolling motor will work just fine. My concern would be with the battery when you capsize. I learned on a Lido 14 and those things are super light / stable so moving it around is no issue at all. May I ask why not just use a paddle for the 50 feet or so? Seems like a lot less cost and hassle.  

I think the problem paddling a small light boat is the you have to lean to each side to make a paddle stroke and the boat will list as a result. If the main is up the boom will swing back and forth and be annoying not to mention the rudder flopping back and forth. I tried this on my Bandit 15 and it wasn't that effective. I would consider sculling. You could fit a half circle fitting on the transom and once you get the technique down move pretty effectively for 50 feet. Off Center Harbor has some Vids posted on this subject and you get to view a few free.  

Of course you could buy an electric motor with a water proof battery like a Torqeedo. I have a 503 on my dinghy. Kayak Trolling Motor - Ultralight 403 A -Torqeedo Electric Outboard with direct drive - Travel 603 - Torqeedo  

Okay so.... one more thing to consider. Once you put a motor on it, you have to register it, display a registration number & tags and pay annual registration fees. COST and HASSLE That might be another reason to stick with human power.  

"No officer. That's not a motor. It's a blender but I don't have another way to stow it!"  

SailingLoto

I used an old transom mount minnkota and small car battery the first couple times I ever went sailing. Worked fine. I had to go 250-300 yards in and out. Zero issues. Light, easy to remove and stow. The battery was from a mid 90s civic and fit directly infront of my trolling motor. Gas was a definite upgrade for me, but you on a small boat, going such a short distance.... I think it would be ideal  

sloughsailer

When the motor on my 3000 LB Columbia 22 self destructed I installed an oarlock on the transom and got a long oar. With a little practice I was able to scull anywhere I wanted to go. One windless night I sculled 2 miles against the current without a great deal of effort. Your 14 foot dingy will scull easily.  

I used a trolling motor on my 16' AMF Sunbird for years. The 'bird was already titled so that wasn't an issue. But when I sold the 'bird and put the trolling motor onto my 8' Walker Bay, I had a Texas Game Warden give me a warning about registering the Walker Bay. I used a small AGM battery to power the trolling motor. I still have the trolling motor if you want it. Just collecting dust here at Canyon Lake.  

I used a 22 lb thrust Minnkota on a Taser to motor out of the dead air in an inlet ramp and get back across the lake if the wind died. Battery was mounted under the mid thwart and a dead-man switch. Do use a dead-man switch for any smaller boat/dingy for safety. (momentary push-on switch).  

I've used a really small trolling motor on a boat that weighed 500 lb alone. I can motor around for at least a couple hours on a lawn mower battery.  

I use an older 12-volt Minnkota 48LB thrust trolling motor on my Macgregor 26S for electric-only lakes. It pushes me at three knots in light wind. I've used it the whole day (without sailing) at times with six people on board.  

I used a 36lb thrust one summer on my SJ21, and it worked great. I would recommend an AGM battery just because of the motion, you don't want to expose the plates during discharge.  

Crazy Dave Condon

You have to ask your state if registration and/or titling is required. Virginia requires it even with a trolling motor

bgstar19 said: Hey George, What size battery (amp- hours?) did you use to motor around all day on your 26S with the 48 lb thrust trolling motor? I've got a 1983 O'Day 19 with a very finicky 5 hp 2 stroke Mercury outboard that failed to start on a number of occasions as I tried to motor back to the crowded marina, making for long frustrating returns to the dock. I'm guessing that a 48 lb thrust trolling motor would work for my sailboat as well based on your experience. Click to expand

Philly2DC2LBI

New to the site, still a sailing newbie relatively as well, this is exactly the conversation I was looking for. I'm on a small, narrow inlet off Barnegat Bay in NJ, have sailed a sunfish for years but recently upgraded size-wise to a used but hardly-used Javelin. Depending on wind/current sometimes I can't tack in/out on the sunfish, so I kept a little paddle with me, but of course that's not an option for a larger boat so I have to figure out best solution. Electric trolling motor seems the best choice, but the range of options is a little overwhelming. I'm assuming I need one that's saltwater rated, but not sure about shaft length/how powerful. Cheapest seems Min-Kota, they are all on backorder for weeks (supply chain problems with the pandemic, apparently), so looking for a used one or I have to drive to a dealer. I see George's tip above on what battery to get - any tips on the battery storage/housing? Any other safety features needed with a battery on board??  

Philly2DC2LBI, I don't know what the difference is between the saltwater & fresh water motors, like if it's just the paint? If it was just the paint you could paint it yourself with some Rustoleum or the like. You would want to put the battery by the transom, the trolling motors don't like long cords. I would put some kind of grippy pad to keep it from wanting to slide and maybe a bungie cord to keep it in place for when you heel, or a more permanent battery box install. I buy used all the time, craigslist, facebook marketplace, offerup... I think I paid $75 for my 48 LB thrust troller out of season (the time for deals). Keep an eye out at garage sales & flea markets also. I paid $5 for a 12 LB troller at a Habitat For Humanity store years ago and that thing still works great on my 14' crestliner V hull boat.

Description

Snug harbor 18.

Designed based on our extremely popular Duffy 18′ Packet and 18′ Balboa models, the Duffy 18′ Snug Harbor features some exciting new improvements. One of the major differences is the new, redesigned hull, which has been widened to really open up the interior space of the boat and give individuals the freedom to move around freely inside the boat. The Snug Harbor comes in at a full foot wider than our Duffy 18′ Packet II model. Combine the extra width of the boat, along with the unfixed, movable tables and the side-steering helm (thanks to our patented Duffy Power Rudder™), and you’ve got a completely different boat with an open interior to move about. The Snug Harbor has become one of our most popular models available thanks to the redesigned shape of the boat. The beautiful spacious interior offers solid wood forward and aft tables, along with a center galley which can accommodate the optional refrigerator! The new three step entry on both sides of the boat makes it extremely easy for anyone to get in and out of the boat! There’s also a built in ice chest under the aft side seat! The fully insulated ice chest drains straight to the bilge pump. With the automatic float switch sensor, there is no need to take the ice out yourself! One of the biggest changes to come to the 18 Snug Harbor is the location of her batteries. Rather than being under the seats like on our previous models, the batteries are now located in the keel of the boat. This provides great stability and tracking, along with opening up the space under the seats for storage! Our new “”Duff Eze III” polycarbonate window system is fully UV proof, and keeps you warm and toasty on the coldest of days. The enclosure will also keep any rain or dirt outside the boat, without the need of a full boat cover! Just unplug, untie, and unwind! Like all Duffy models, the 18 Snug Harbor comes with the new Fusion Marine 50 watt per channel stereo. Play music, or take calls wirelessly with Bluetooth, or plug in for a quick charge while you play your favorite songs through the USB port! We here at Duffy are very proud of this new model, and we look forward to building you one of America’s first and finest electric boats as we have since 1970! Like all of our Duffy Electric Boats, the 18′ Snug Harbor is made in USA.

Our products

We use the most recent techniques to build our motors. Our products are robust, durable, innovative and are all based on a simple ‘Plug and Play’ formula.

Electrical Inboard motors; Small in size, but large in performance.

Combi E-thruster Outboard motors; whisperquiet, robust and reliable.

Combi Nautic saildrive or steerable POD motors; Compact, durable and quiet

Combi Paralel hybrid systems; Powerful, very efficient and durable

Assemble your own electric propulsion system

With our configurator you can easily check what propulsion suits you best for your boat.

Our inboard motors are available in various capacities and can be used as a single and a dual drive. Our motors are made for long-term performance and have a high reliability. If you are looking for a single replacement motor or a complete new set-up including a propeller shaft for a newly vessel, our inboards provide you with the solution.

Combi E-Thruster electric outboard engines are characterized by their robustness, sleek design and reliability. Our motors have been developed for long-term use and have a high efficiency, as demonstrated by their use in rental boats across many locations.

The Combi Nautic is a whisper-quiet engine for optimal boating pleasure. The Combi Nautic is available as a Saildrive (fixed model with separate rudder ) or as Steerable POD motor (Steerable POD) mounting in rudder or rudder trunk. The POD can also be built into, for example, a rudder as a custom solution.

The Combi hybrid is a parallel l hybrid solution to combine electric propulsion with a combustion engine. When you sail on your internal combustion engine, the electric motor works as a generator to charge the battery pack. This way you can use a relatively small battery pack. In short, all the benefits in a single system.

Protests in Russia Put Spotlight on Wartime Ethnic Grievances

The trial and conviction of an activist in the Ural Mountains region sparked one of the biggest outbreaks of social unrest since the start of the war.

By Anatoly Kurmanaev

The trial of a minority rights activist in Russia this week sparked one of the biggest outbreaks of social unrest in the country since the start of the war in Ukraine, highlighting the strain the conflict has imposed on Russia’s complex ethnic relations.

Hundreds of protesters clashed with the police on Wednesday in the provincial town of Baymak, near Russia’s border with Kazakhstan, after a local court sentenced an advocate for the local Bashkir ethnic minority to four years in prison. He was convicted of inciting ethnic discord and discrediting the Russian army.

A Russian legal aid group, OVD-Info, said that at least 20 people had been detained and another 20 injured in the protest. A video published on social media, and verified by The New York Times, showed protesters throwing snowballs at a wall of police officers in riot gear; other videos showed the police leading some protesters away and protesters exposed to what appeared to be tear gas.

Tensions in Baymak, in the Republic of Bashkortostan region of Russia, flared on Monday after residents gathered outside the courthouse to protest over the trial of the activist, Fail Alsynov. Mr. Alsynov had called for greater cultural and economic autonomy for the predominantly Muslim Bashkir people of Russia’s Ural Mountains. Mr. Alsynov has also criticized Russia’s invasion of Ukraine and the 2022 mobilization, which he said had disproportionally affected ethnic minorities like the Bashkirs.

“The smartest, strongest Bashkir men are being put under fire,” Mr. Alsynov said on social media last year, a post that contributed to his arrest. “This is not our war. Our land has not come under attack.”

The trial of Mr. Alsynov has shown how long-running ethnic grievances in the Russian provinces can swiftly assume antiwar undertones, in a potentially explosive mix that the government has demonstrated in Baymak that it will act decisively to prevent.

“The Kremlin is afraid of nationalism and separatism,” said Abbas Gallyamov, an exiled ethnic Bashkir and former speechwriter for President Vladimir V. Putin of Russia, in a written response to questions. “Putin and his circle were traumatized by the collapse of the U.S.S.R. and are worried that Russia will repeat its fate.”

Videos of the protests showed hundreds of security officers in full riot gear clashing with demonstrators outside the courthouse of Baymak, a town of 15,000 people, and local media reported that mobile data access in the area had been restricted.

Several social media accounts that covered the protests have disappeared from platforms popular in Russia this week, and the Russian Prosecutor’s Office in Moscow said on Wednesday that it had opened a criminal case over the incitement of riots.

OVD-Info, the rights group, said two students from Bashkortostan’s capital, Ufa, were detained on Thursday, seemingly in connection with Mr. Alsynov’s case.

The crackdown came despite attempts by the protesters to emphasize that their focus was on supporting Mr. Alsynov, rather than criticism of the federal government or calls for greater autonomy.

“We are the people of the Republic of Bashkortostan, a subject of the Russian Federation. We are not extremists,” one Baymak protester said in a video addressed to Mr. Putin on Monday.

The leader of Bashkortostan, Radiy Khabirov, said in a social media post on Thursday that his office had worked to charge Mr. Alsynov with extremism and to ban his organization, Bashkort, which had promoted Bashkir language and culture and opposed mining in the region.

“I must protect people from any attempts to weaken interethnic unity,” Mr. Khabirov said in a video posted on his Telegram channel.

In his public war speeches, Mr. Putin has portrayed Russia as a harmonious multiethnic society united against what he claims are Western attempts to dismember it. He has lauded ethnic minorities for their contribution to the war and stressed the shared history of the country’s diverse ethnic groups and a common commitment to what he calls “traditional values.”

But Mr. Putin’s use of Russian imperialist rhetoric to justify the war in Ukraine has also empowered once-ostracized far-right movements, leading to an outbreak of xenophobic rhetoric.

Mr. Alsynov, the convicted activist, made reference to the Kremlin’s conflicting messages in his social media post about the war last year.

Mr. Putin, he wrote, had argued for action because “in Ukraine they are harassing Russian people, they don’t teach the Russian language,” contrasting that stance with what he characterized as mistreatment of the Bashkir language in Bashkortostan.
