About the Oyster Sj35 Sailboat

Designed by Stephen Jones and built by Oyster Marine Ltd. starting in 1983, this 35-footer represents an early entry in Oyster's renowned lineup of premium cruising yachts. The Sj35 carries the distinctive Oyster DNA of thoughtful construction and seaworthy design, though in a more compact package than the builder's larger ocean-going vessels. With a displacement of 8,600 pounds and substantial ballast of 3,700 pounds, the Sj35 offers impressive stability for coastal and offshore cruising. The fin keel with spade rudder configuration provides responsive handling, while the fractional sloop rig delivers versatility across varying wind conditions. Her 563 square feet of sail area creates a balanced sail plan that should perform well in both light airs and stronger winds. The moderate comfort ratio of 17.54 suggests this yacht strikes a nice balance between performance and onboard livability, making her suitable for extended cruising without sacrificing sailing characteristics. Her capsize screening value of 2.23 indicates good stability margins for offshore passages, while the 7-knot hull speed provides respectable passage-making capability. Built with fiberglass construction, the Sj35 benefits from Oyster's reputation for quality craftsmanship and attention to detail that has made the brand synonymous with premium cruising yachts.
