Designed by Phil Southwell and built by Fortuna Catamarans in South Africa from 1998 to 2005, this 36-foot catamaran represents solid value in the performance cruising multihull market. The twin-keel hull configuration and shallow 3.6-foot draft make her particularly well-suited for exploring shallow anchorages and beachable destinations that deeper-draft monohulls cannot access. With her fractional sloop rig carrying 908 square feet of sail area and a favorable sail area to displacement ratio of 23.75, the Island Spirit 37 delivers respectable performance while maintaining cruising comfort. The generous 22-foot beam provides exceptional interior volume and stability, accommodating spacious living quarters typical of catamarans in this size range. Twin 18-horsepower engines offer reliable auxiliary power and excellent maneuverability in tight quarters. The GRP construction ensures durability for extended coastal cruising, while the moderate displacement of 15,212 pounds strikes a reasonable balance between carrying capacity and sailing performance. This catamaran excels at coastal and island-hopping adventures, particularly in areas where shallow draft is advantageous. While not designed for serious offshore passages or racing, she offers comfortable family cruising with the inherent stability and space advantages that make catamarans popular among recreational sailors seeking room to spread out.
