About the Columbia 27 Sailboat

Designed by the renowned William Tripp Jr. and first launched in 1970, this 27-footer represents classic American yacht design from the golden age of fiberglass sailboat production. Built by International Marine in Australia, the Columbia 27 features a traditional masthead sloop rig with a modern fin keel and spade rudder configuration that provides responsive handling and decent windward performance. With a displacement of 6,235 pounds and 2,800 pounds of ballast, this boat strikes a reasonable balance between stability and performance. The hull speed of 6.31 knots makes it suitable for relaxed coastal cruising, while the sail area of 310 square feet provides adequate power in light to moderate conditions. The beam of 8.5 feet offers comfortable interior space without sacrificing seaworthiness. The Columbia 27 earned a solid reputation as an affordable entry point into sailing, particularly appealing to families and new sailors seeking a manageable yet capable cruiser. The comfort ratio of 23.68 suggests a relatively stiff, quick motion that favors day sailing and short coastal passages over extended offshore voyaging. The capsize screening value of 1.85 indicates good stability characteristics for protected waters and nearshore sailing adventures.
