What this video covers
Sven Yrvind shapes a flat daggerboard for a shallow-draft, high-latitude boat intended for a 14,000-mile nonstop voyage.▶ 0:04 The project involves rounding the edges of the board to improve its hydrodynamic profile, transitioning from a flat-faced design to a more refined shape.▶ 2:16 After grinding the edges, the surface is roughed up to ensure proper adhesion for the final paint application.▶ 2:39 The boat, currently undergoing extensive painting, also receives a yellow finish on the hull.▶ 0:47 During the rigging process, the magnet hitch is preferred over the rolling hitch for securing lines, as it offers easier adjustment and reliability.▶ 1:10 The daggerboard preparation is completed while awaiting bottom paint for the hull.▶ 2:03 Proper shaping of the daggerboard edges reduces drag and improves the performance of the foil.
