What this video covers
Sven Yrvind modifies the rudder assembly on his small boat by heating and removing epoxy-bonded components with a specialized heating tool.▶ 0:00 He avoids cutting the structural beam, instead using localized heat to extract the material.▶ 0:01 Following the rudder work, Yrvind calculates the vessel's displacement and load waterline. He estimates the boat will weigh 550 kilograms at the design waterline, with an additional 30 kilograms of flotation provided by the vinicell core.▶ 2:24 Each centimeter of immersion adds approximately 50 kilograms of displacement.▶ 2:34 Based on these calculations, he determines the boat can carry a total load of 830 kilograms, allowing for 324 to 350 kilograms of additional supplies.▶ 2:48 Yrvind plans a long-distance voyage from South Africa to Dunedin, New Zealand, estimating a duration of over 200 days.▶ 3:51 He acknowledges that final displacement figures remain speculative until the boat undergoes sea trials.▶ 4:11
