Judging: 65% speed · 10% appearance · 10% comfort · 15% strength
0.15m significant wave height · 3.9kn headwind · 0m/s following current.
0.47m estimated freeboard · 2634kg buoyancy at the gunwale · 9.7kW effective propulsion.
Speed solves engine power against estimated friction, wave-making, planing, and wind resistance. Buoyancy is calculated from the panel geometry. The drag and material models are approximate and uncalibrated; this is not a naval-design safety tool.
Meet returning rivals. Challenge bonuses are awarded once.
