About the Windrush 25 Westerly Sailboat

A compact and characterful British cruiser, the Westerly Windrush 25 comes from one of the UK's most trusted and prolific production boatbuilders. Westerly Yachts built a strong reputation throughout the latter half of the twentieth century for producing robust, family-friendly sailing boats well suited to the coastal and inshore waters around Britain and Europe, and the Windrush 25 sits comfortably within that tradition. Designed with the weekend cruiser in mind, this is a boat that prioritises practicality and seaworthiness over racing performance. Westerly's builds were consistently known for solid GRP construction, sensible layouts, and a reassuring stiffness under sail — qualities that made them popular with first-time buyers and experienced sailors alike. The Windrush 25 would appeal to those looking for an approachable coastal cruiser with enough capability to handle variable conditions without being overly demanding. For buyers researching this model, its Westerly pedigree means a well-supported secondhand market, an active owner community, and generally good availability of parts and knowledge — all valuable considerations when purchasing a classic British production cruiser.
