Summary Analysis of the Design Ratios for the  Westerly 22

1. A Sail Area/Displacement Ratio of 17.0 suggests that she'll approach her maximum hull speed readily and satisfy the sailing performance expectations of most cruising sailors.

2. A Ballast/Displacement Ratio of 33.3 means that a sailboat like the Westerly 22 (which doesn't have a stiffness-enhancing bulb keel), is likely to benefit from being reefed early to keep her sailing upright in a moderate breeze.

3. A Displacement/Length Ratio of 228, tells us she's a moderate displacement cruiser, which means she'll carry all your cruising gear without it having a dramatic effect on her performance. Most of today's sailboats intended for offshore cruising fall into this displacement category.

4. Ted Brewer's Comfort Ratio of 17.0 suggests that crew comfort in a seaway is similar to what you would associate with the motion of a lightweight racing boat. Upwind she'll slam enough to shake your fillings out with a motion that cruising sailors have no desire to get used to.

5. The Capsize Screening Formula (CSF) of 2.1 indicates that a Westerly 22 would not be the wisest choice of sailboat for ocean passage-making owing to the lower resistance to capsize in strong winds and heavy seas that is associated with sailboats with a CSF of 2.0 and above.

More about the Westerly 22

Accommodation

Four people can sleep comfortably on the Westerly 22, which has a cozy forecabin with a double "V"-shaped berth and a main cabin with two long couches that can be used as berths. The galley area is split between the two sides of the main cabin, with a stove and grill on the left and a sink on the right. A small desk for navigation is also on the left, above the stove. The toilet is hidden under the "V"-berth in the forecabin.

Sail Plan & Rigging

The Westerly 22 has a Gunter rig or an optional masthead sloop rig. The Gunter rig has a large roller-reefed mainsail and a jib, while the masthead sloop rig has a mainsail and a genoa. The sail area is 227 sq ft for both rigs. The Gunter rig is easier to set up and lower and can perform well in a good breeze.

Keel Options

The Westerly 22 has twin fixed keels made of iron. The draft of the boat is 2'3", which allows it to sail in shallow waters and be easily trailerable.

Sailing Performance

The Westerly 22 has a hull speed of 5.74 kn and a displacement-to-length ratio of 253, which indicates a moderate-performance cruiser. The boat is stable, seaworthy and capable of long-distance voyages. In 1965, the Gunter rigged Westerly 22 "Young Tiger" did an Atlantic crossing with three adults.

Average Cost

The average cost of a secondhand Westerly 22 sailboat depends on the condition, equipment and location of the boat. Based on some online listings, the price range can vary from £1,500 to £4,000.

Denys Rayner, the Designer

Denys Rayner founded Westerly Marine Construction Ltd., which became one of Britain's most successful yacht building companies. Some of the other sailboats he designed are:

• Westcoaster 20: A wooden sailboat that was built by Beacon Boats Co Ltd starting in 1960;
• Westerly 30: A larger sailboat that was introduced in 1966;
• Westerly Windrush 25: A twin keel sailboat that was launched in 1966;
• Westerly 25: A similar sailboat to the Windrush 25 that was introduced in 1964;
• Westerly Nomad 22: A modified version of the Westerly 22 with a different coachroof and a larger cockpit;
• Westerly 25: A similar sailboat to the Windrush 25 that was introduced in 1964.

Rayner was a pioneer of the 'bilge keel' type of small yachts, which could be beached easily and had better stability. He died in 1967, leaving behind a legacy of innovative and popular designs.

Westerly 22

Westerly 22 is a 22 ′ 2 ″ / 6.8 m monohull sailboat designed by Denys Rayner and built by Westerly Marine between 1963 and 1967.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

The first Westerly and derived from the earlier plywood WEST COASTER 20. Also available with a ‘Bermudan’ sloop rig as pictured here. A Volvo Penta M1 inboard was available as an option.

Westerly Sailboats Information

Westerly sailboats were built by Westerly Marine Construction, Ltd., a company that was founded by Commander Denys Rayner in the early 1960's. Rayner was a sailboat designer at heart with a passion for rugged little boats that could be taken to sea and brought home with little fuss. In fact, he wrote several books on sailing small crafts, and although technology has transformed sailing in the years since, his books and guides still manage to impart a timeless wisdom on the subject. in the late 1950's Rayner collaborated with a local manufacturer of plywood caravans to design plywood dinghies to be offered along with them. This turn of events led to the founding of the Beacon Boat Company, where Rayner also began building and selling small sailboats with very distinctive designs which eventually led to the first Westcoaster. Rayner built and sold about 60 of his Westcoaster sailboats, and along the way began experimenting with a new process of building hulls with glass reinforced plastic, or GRP. In 1963 he moved his expanding enterprise of GRP family sailing boats to a new location as the firm of Westerly Marine Construction, Ltd. Westerly Marine grew to become Britain's largest yacht building company and during the 1970's was considered a leader in family yachts. The Westerly 22 was the first sailboat produced by Westerly Marine and was based largely on Rayner's original Westcoaster design. The Westerly 25, 28, 21, and 33 followed as new models emerged, sometimes several per year, until Westerly Sailboats ceased operations in 2000 .
