Sven Yrvind's twin-keeled boat grounded in workshop
What this video covers
Sven Yrvind utilizes a combination of twin keels and a forward-mounted daggerboard to optimize boat balance and stability for long-distance cruising. The twin keels serve two primary functions: they lower the center of gravity for increased stability and allow the vessel to stand upright on the seabed during low tide.▶ 0:40 Constructed from bronze, the keels also provide anti-fouling properties.▶ 1:17 The forward daggerboard allows the sailor to adjust the center of lateral resistance, enabling the boat to maintain a weather helm when sailing to windward and a lee helm when running downwind.▶ 3:26 By retracting the board in heavy following seas, the sailor prevents the boat from fighting the natural tendency to round up, which reduces strain on the autopilot and wind vane.▶ 4:12 This configuration prioritizes cruising efficiency over racing performance, allowing the vessel to maintain balance without constant steering corrections. Adjusting the daggerboard position relative to the wind direction ensures the boat remains stable and easy to handle in storm conditions.
