Westsail 28

Description

The Westsail 28 is a compact American fiberglass bluewater cruising cutter designed by Herb David as a "pocket" world cruiser emphasizing heavy displacement, robust construction, and offshore capability in a smaller hull. It was built by Westsail Corporation (USA), with hulls hand-laid in solid fiberglass (plywood sandwich deck) and offered both as factory-finished boats and in various stages of kit completion. Introduced in 1975, early boats underwent refinements including increased ballast (from ~3,500 lb to ~4,200 lb, adding ~4 inches of draft), enlarged sail area (from ~480 sq ft to ~545 sq ft working sail), and a larger rudder with a characteristic step for better balance and tracking; the design features a full keel, cutter rig for versatile heavy-weather sail handling, and a practical interior with 4–5 berths suited to long-distance cruising or liveaboard use. Production ran from 1975 to 1979, during which only 78 hulls were completed—far fewer than the iconic Westsail 32—making well-maintained examples relatively rare today despite their cult following for proven seaworthiness and global voyaging history.

Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them.
