About the Corsair 36 Westerly

Westerly Marine built a reputation for producing robust, seaworthy cruising yachts, and the Corsair 36 represents their commitment to creating boats capable of handling challenging conditions with confidence. This mid-sized cruiser embodies the British builder's philosophy of prioritizing structural integrity and sea-keeping ability over pure performance. Designed primarily for coastal and offshore cruising, the Corsair 36 features the solid fiberglass construction that became Westerly's hallmark during their productive years. The boat's moderate proportions and sensible layout make it well-suited for couples or small families seeking reliable passage-making capabilities without sacrificing comfort below decks. Like other Westerly designs from this era, the Corsair 36 emphasizes seaworthiness over racing performance, making it an attractive option for sailors who prioritize safety and predictable handling characteristics. The boat's reputation centers on its ability to handle rough weather conditions while providing a stable platform for extended cruising. While Westerly ceased operations years ago, their boats maintain a loyal following among cruising sailors who appreciate the builder's emphasis on durability and practical seamanship. The Corsair 36 continues this tradition, offering proven offshore capability in a manageable size.
