Vernon and Marie-Morgane test four propeller and hydrofoil configurations on a new Tohatsu outboard engine to optimize dinghy performance while carrying heavy loads in Wayag, West Papua.0:37 The crew measures time-to-plane and top speed for each setup using a standing start at wide-open throttle with a full fuel tank and two people aboard.2:09 The standard propeller achieves a top speed of 16.7 knots and reaches plane in 8.72 seconds.3:26 A larger, lower-pitch propeller improves time-to-plane to 8.05 seconds but reduces top speed to 15.7 knots.4:46 Adding hydrofoil wings to the larger propeller results in a 7.93-second time-to-plane and a 12.7-knot top speed.6:11 The final configuration, pairing the standard propeller with the hydrofoil wings, yields the fastest time-to-plane at 6.9 seconds and a top speed of 13.9 knots.7:45 The crew concludes that the standard propeller combined with hydrofoil wings provides the best performance for heavy loads, prioritizing planing speed over maximum top-end velocity.7:45
