Design and Construction
The Westsail 43 is built around a solid fiberglass hull with a long, full keel and an attached rudder, a configuration that trades agility for directional stability and grounding protection. At a displacement of roughly 31,500 pounds with 11,000 pounds of lead ballast, the boat sits in the “ultra heavy cruiser” class by displacement-length ratio (about 380), and only 8% of comparable designs are heavier ultra heavy cruiser classification. The ballast ratio of 35% is higher than 27% of similar sailboats, while the length-beam ratio of 3.30 makes her roomier than 54% of all other designs. Her motion comfort ratio of 43.9 is calculated as more comfortable than 96% of similar sailboat designs, a figure consistent with the mass and beamy hull form. She trims at roughly 1,509 pounds per inch of immersion, so she sits deep and changes trim slowly under load.
Rig and Handling
The cutter rig carries more rig than 50% of all similar sailboats, and the sail plan is conservative rather than racy. With the ISO 8666 reference sail the sail-area-to-displacement ratio is 15.2; with a 135% genoa that rises to 18.1, and even so the SA/D indicates she is faster than only 12% of similar sailboats in light wind. The theoretical hull speed is 7.7 knots, set by the 33-foot-4-inch waterline. Standing and running rigging follow practical cruising dimensions: mainsail, jib/genoa, and spinnaker halyards are all 34.1 meters long and 14 mm in diameter, while sheets run 13.1 to 32.7 meters at 16 mm. The wetted bottom surface of about 462 square feet and the long-keel hull argue for predictable tracking rather than quick acceleration.
Accommodations and Layout
The Westsail 43’s 13-foot beam and 33-foot waterline produce a voluminous interior typical of the Crealock Westsail approach, with the rear-cockpit layout distinguishing her from the Westsail 42. The capsize screening value of 1.65 and the comfort-oriented ratios point to a boat intended for offshore living and passage-making, not coastal sprinting. Her large hull and heavy build provide the platform for extended cruising loads without disproportionate loss of performance, given the modest theoretical hull speed.
Known Issues
The known facts center on performance boundaries—light-air speed deficit and deep draft variation between 5.68 and 5.98 feet dependent on load—rather than on material failures.
The Verdict
The Westsail 43 is a deliberately old-fashioned, massively built cutter for sailors who value comfort and seaworthiness over pace. She rewards patient passage-making and load-carrying with a hull that the numbers place among the most stable and roomy of her peers, yet asks the owner to accept modest light-wind performance and a long-keel draft.
Pros
- Ultra-heavy cruiser build with high motion comfort ratio (more comfortable than 96% of similar designs)
- Long full keel with attached rudder for directional stability
- Cutter rig with generous rigging dimensions for offshore service
- Roomy beamy hull (roomier than 54% of comparable designs)
Cons
- Slow in light air (faster than only 12% of similar sailboats under SA/D)
- Deep draft varying to nearly 6 feet dependent on load
- Fewer than 100 built
