My most popular design, Kahuna is a good choice for extended offshore sailing. Hull volume and carrying capacity are both much greater than with Wynfall or Austral, and her larger size allows for features such as built-in water tanks (with a capacity of 100 gallons). She retains the buoyant hull shape, fine entry and clean run that make her smaller sisters a joy to sail.

Plans include drawings for gaff and bermudan rigs, and for several layouts. Construction options include carvel, strip and strip+ veneer construction.

A Kahuna is sailing in Australia, and another was launched in 2016 in North Carolina. Boats are currently building in the US (North Carolina, New York), Russia, and Italy.

secure rig for ocean sailing. A gaff rig is also available.
