anti-trip chine sides. Canted decks combined with wedge-shaped planform
minimizes frontal resistance. All surfaces are developed for sheet plywood
planking for minimum hull weight.

pleasure use: 7.5 hp
 
- 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.
