What this video covers
Sven Yrvind is outfitting a small, amphibious, high-latitude boat with a 19-meter length of 4.8mm to 5mm chain to serve as a drogue.▶ 1:25 The chain stores in a box measuring approximately 20cm by 17cm by 12cm located below the tiller.▶ 3:01 To deploy the system, the chain streams out through fittings and attaches to a rope led from the bumpkin.▶ 2:07 This configuration aims to provide directional stability when sailing downwind with dihedral side-by-side sails during storms.▶ 2:31 The 8mm rope passes through the 8mm links of the chain to secure the connection.▶ 3:26 Yrvind plans to verify the performance of this drogue setup during an upcoming shakedown voyage.▶ 2:49 The design relies on the principle that thinner chain allows for greater length and increased drag resistance relative to weight.▶ 1:09
