  • Length: 11′ (3.35m)
  • Beam: 4′ 5½″ (
  • Draft board up: 8″ (20cm)
  • Draft board down: 27″ (69cm)
  • Depth amidships: 21½″ (55cm)
  • Boat weight (approx.): 110 lbs (50 kg)

In a nod to performance potential, the boat has a narrower waterline and steeper deadrise than many traditional boats of her size. A simple daggerboard and kickup rudder will make it easy to get her on and off the beach.

The construction and layout are traditional: She is built of copper-riveted planks on steam-bent white-oak frames and can accommodate four people for a daysail.

The lug rig is based on one developed by the late Sam Manning. It is a standing-lug arrangement; the lug is always on the same side of the mast, but the luff is close to, and nearly parallel to, the mast. This differs from a more conventional setup that has about 20 percent of the sail ahead of the mast—an arrangement that affects sail shape when the sail is to windward.
