Power Displacement sailer/cruiser

A modern, triple dart hull, the Duck 37 was inspired by the combination of low displacement trollers combined with the low friction and high stability of offshore sailboats. The result is a hull easily driven under power and/or sail at almost 8 knots with a 1000+ mile range.

Designed for both inside and outside steering stations, the Duck 37 is able to handle the elements while at the same time able to minimize uncomfortable motion in a seaway. The soft hull sections, combined with the full length keel significantly reduce the motion as compared. The convenient self-furling, loose-footed headsail significantly extends the range and comfort of the boat, while providing an added level of safety in case of engine failure.

The Duck 37 provides all the comforts and range of a displacement power boat, combined with fuel economy and silence of a convenient, modern sailing system.
