About the Intrepid 28 Sailboat

Designed by Rolf Van Der Sleen and built by Intrepid Yachts beginning in 1979, this 28-footer represents a thoughtful approach to coastal cruising with a touch of performance potential. With only ten hulls produced, the Intrepid 28 remains a rare find that combines seaworthiness with manageable size for small crews or couples. The design features a fin keel with rudder mounted on a skeg, providing good directional stability while maintaining reasonable maneuverability. At 7,500 pounds displacement with 3,100 pounds of ballast, she carries enough weight for stability in challenging conditions while remaining light enough to be responsive in lighter winds. The masthead sloop rig with 377 square feet of sail area delivers adequate power for coastal passages. Her comfort ratio of 22.61 suggests a motion that favors seakindliness over racing performance, making longer passages more pleasant. The capsize screening formula of 1.94 indicates good stability characteristics for coastal and near-offshore sailing. With a beam of 9.50 feet on a 28-foot length, the Intrepid 28 offers reasonable interior volume without compromising her sailing characteristics. This is a boat well-suited for weekend cruising and coastal exploration, particularly appealing to sailors who appreciate distinctive, limited-production designs.
