Hull type: Semi-displacement hard chine hull with practical cruising speed of 7 1/2 knots. Build in plywood or "one-off" fiberglass. Bottom features deep bulbous forefoot with reverse curve at the chine. Plywood version: double diagonal plywood planking on the bottom to a total thickness of 3/4", sheet plywood sides to 1/2". Topsides feature broad flare with raised deck forward. Fiberglass version utilizes fiberglass planking or PVC foam or balsa core sandwich construction.
Power: Single diesel engine recommended of approximately 25 continuous shaft horsepower for 7 1/2 knot cruising speed. However, a reserve of approximately 50% additional power is recommended to offset adverse wind and sea conditions. Engine weight should range between 500 and 700 lbs. Gasoline power is optional.
Can the hull be extended or shortened? Yes. Up to 10% by re-spacing the frames from the aft end of the stem to the transom a proportional amount. We do not recommend increasing the beam.
