De Pan

This appears to be the first Sparkman & Stephens powerboat launched (although design #3 was a powerboat design, it was not built). The year was 1931. She was heavily built by one William Bunce of Huntington, Long Island. She was powered by twin 4 cylinder engines of 56hp each for a cruising speed of 10 knots.

The general arrangement looks quite practical for a 43' boat with a cabin including en-suite head on each end of the boat separated by the engine room/wheelhouse for reasonable privacy for two couples.

The hull lines look definitively influenced by sailing yacht design. There was 5,000 lbs of ballast integral to the skeg.
