Design #623.
Available as a cutter or sloop. Also available with optional offshore cruiser layout called the Truant Turtle. Both are illustrated above. The turtle was designed for extensive offshore cruising. While the rig and hull are the same as the 370, the Turtle was redesigned from the sheer up.
