The Westerly 25 represents a pivotal moment in the history of fiberglass boat building, serving as the first major production success for Westerly Marine Construction. Launched in 1964 and designed by Commander Denys Rayner, this model was the vessel that effectively "put Westerly on the map," moving the company from a small-scale operation to a prolific manufacturer. While the builder’s California namesake, Westerly Marine Inc., eventually focused on high-performance custom composites, the original 25-footer was a sturdy, mass-market cruiser built for the rugged conditions of the English Channel. With 327 hulls produced between 1964 and 1967, it established the "bilge keel" identity that would define the brand for decades. The Westerly Owners Association notes that the boat was specifically designed to provide a seaworthy, affordable platform for families, featuring a robust layup and a surprisingly voluminous interior for its era.
