About the Ovni 28 Sailboat

Philippe Briand's Ovni 28 represents an innovative approach to bluewater cruising, combining the legendary French designer's expertise with Alubat's pioneering aluminum construction techniques. Built from 1978 to 1986, this 28-footer established the foundation for what would become one of sailing's most respected offshore cruising lines. The centerboard trunk configuration sets the Ovni 28 apart from conventional deep-keel cruisers, allowing access to shallow anchorages and beaching capabilities while maintaining excellent offshore performance. With a displacement of 6,800 pounds and aluminum construction, she strikes an impressive balance between strength and weight, contributing to her reputation for seaworthiness in challenging conditions. Her masthead sloop rig carries 536 square feet of sail area, providing adequate power for her displacement while remaining manageable for short-handed crews. The moderate beam of 9.84 feet ensures comfortable interior volume without sacrificing sailing performance, while the 6.40-foot draft provides good directional stability when the board is deployed. The Ovni 28's comfort ratio of 20.14 indicates excellent motion characteristics in seaways, making her particularly well-suited for extended offshore passages. Her capsize screening formula of 2.08 reflects solid stability margins, reinforcing her reputation as a capable ocean-going vessel despite her modest size.
