Sven Yrvind details a new ventilation system designed to keep cabin air dry while preventing water ingress during a capsize.Watch The system utilizes a central chamber that acts as a water trap, with drainage routed into the daggerboard trunk.0:41 By positioning the intake pipe in the center of the boat, the design ensures that even at a 180-degree heel, the intake remains above the waterline.3:07 Yrvind plans to incorporate this system into a new, lighter vessel, which he estimates will weigh 800 kilograms—a reduction achieved by decreasing ballast from 150 kilograms to 50 kilograms and refining the hull shape.8:03 The new design features a square transom for increased stability and a sail area of 9 square meters, more than double that of his previous boat.5:36 Yrvind intends to sail this vessel from Madeira to Cape Town and then to Dunedin, relying on a new AIS unit and an improved sculling oar for safety in light winds.9:50
