Westerly 33 ketch

Brief details


Westerly Marine, Hampshire

The Westerly 33 was the bigger, beamier and heavier successor to the long-running Longbow/Renown range, and whilst also designed by Laurent Giles, and retaining the distinctive bow knuckle, had a much more elegant coachroof and substantially more interior space, plus a much better standard of interior finish than the older models, with lots of solid wood trim.


33' 3"

Sail area

approx 635 sq ft main. mizzen and genoa


28' 6"




11' 3"




5' 5" fin keel or 4' 4" bilge keel




14,336 lbs


Mercedes OM636 diesel


6,050 lbs



Keel type

Iron fin or twin bilge keels with skeg-hung rudder

The Westerly 33 was introduced in 1977, and over 200 were built before it was replaced by the very similar Discus in 1980, which used the same hull moulding, and continued in production until 1984. Most were ketch-rigged, although sloops were also produced, and they were sold with fin or bilge keel options. "Yachting Monthly" has described them as ".... substantial, safe and comfortable seaboats, popular with families for extended cruising"

With as powerful a diesel as most similar sized motor-sailers, they are nevertheless good sailing yachts, particularly in the fin-keeled models.

Like all Westerlys, they are solidly built, though they do suffer from the vinyl headlinings sagging - these were fitted to almost all early Westerlys and are a common (though entirely fixable) problem
