About the Concordia 40 Sailboat

Designed by the legendary C. Raymond Hunt and built by the renowned German yard Abeking & Rasmussen from 1938 to 1966, this classic masthead yawl represents one of sailing's most celebrated offshore cruising designs. With 103 hulls launched over nearly three decades, the Concordia 40 earned an enviable reputation among serious cruising sailors seeking a boat capable of handling demanding ocean passages while maintaining exceptional seaworthiness. Hunt's timeless design features traditional construction with mahogany planking over oak frames, embodying the finest boatbuilding traditions of both American design philosophy and German craftsmanship. The long keel configuration and substantial 7,700-pound ballast provide exceptional stability and directional control, particularly valuable for extended offshore passages. Her masthead yawl rig offers versatility in sail handling, allowing crews to balance the boat effectively in varying conditions. The generous comfort ratio of 39.29 reflects Hunt's priority on seakindly motion and crew comfort during long passages, while the conservative capsize screening formula indicates excellent stability characteristics. These boats excel at serious offshore cruising and have completed countless ocean crossings, earning respect for their ability to handle heavy weather with confidence. The Concordia 40 remains highly sought after by discerning sailors who prioritize seaworthiness over speed.

Known Issues View all 9 issues →
High
Oak frames are known to develop rot at the turn of the bilge and at frame heads where they meet the deck shelf, particularly where water can collect and ventilation is poor. A thorough survey should include sounding every frame along its full length.
High
The lead or iron ballast keel attachment bolts pass through the oak keel timber and are susceptible to corrosion and the surrounding wood to rot. Keel bolt integrity is a critical survey item; many boats of this age have never had bolts surveyed or replaced.
High
Deck canvas or laid teak decking on surviving examples frequently shows separation from the underlying deck structure, and the carlins and deck beams beneath can hold moisture leading to hidden rot. Soft spots anywhere on deck warrant immediate investigation.
