About the Cobra 750 Sailboat

Designed by David Feltham and built by Cobra Yachts in the UK starting in 1977, this 25-foot sailboat became a popular choice for coastal cruising and club racing during its production run of 500 units. The twin keel configuration sets the Cobra 750 apart from many boats in its class, offering the practical advantage of drying out upright in tidal waters while maintaining reasonable sailing performance. With its masthead sloop rig and 360 square feet of sail area, the boat delivers respectable performance for both recreational sailing and competitive racing. The twin keel design, while slightly compromising upwind ability compared to a fin keel, provides excellent directional stability and allows access to shallow waters and drying moorings that would be impossible for deeper-draft vessels. The fiberglass construction and moderate displacement of 5,800 pounds, combined with 2,240 pounds of ballast, creates a stable platform suitable for family cruising in protected waters. The comfort ratio of 20.46 indicates a relatively stiff, quick motion at sea, while the capsize screening formula of 2.16 suggests this boat is best suited for coastal and near-shore sailing rather than extended offshore passages. The compact 10-horsepower engine provides adequate auxiliary power for maneuvering in harbors and calm conditions.
