What this video covers
Sven Yrvind is re-evaluating the design of his current vessel, deciding to reinstall twin keels despite the weight penalty.1:24 Each keel weighs approximately 77 kilograms, adding roughly 155 kilograms to the boat’s displacement.0:45 While the additional weight reduces the total capacity for food and water, the twin-keel configuration improves stability when the boat is hauled out on land and enhances performance in strong winds.2:31 The keels feature integrated wheels to facilitate easier movement of the boat while ashore.2:26 Yrvind notes that the keels measure 15 centimeters in height and 60 centimeters in length.2:24 The decision follows a period of experimentation with a lighter, single-keel setup and auxiliary side supports.0:57 Yrvind also reflects on his history of boat construction, including the development of an aluminum vessel in Vetlanda during the late 1970s, which suffered from significant corrosion issues shortly after launch.9:24
