What this video covers
Sven Yrvind installs low-friction rings on his boat to manage rigging loads, calculating a total capacity of 3.6 tons across six rings rated at 600 kilograms each.▶ 0:21 He secures the lines with tight knots and applies epoxy to the connections to ensure a rigid fit.▶ 0:53 The rigging configuration routes lines through the rings and under the laces, creating a system that relies on the capstan equation to multiply holding power.▶ 1:13 By increasing the number of turns around the loop, the system gains significant strength based on the friction coefficient and the angle of the line in radians.▶ 2:38 The installation positions the rings close to the boat's tubes while maintaining necessary clearance for the lines.▶ 1:49 Yrvind plans to clean and smooth the epoxy joints before testing the rigging under load.▶ 2:09
