O que este vídeo aborda
Sven Yrvind designs a new boat featuring dual daggerboard-style rudders to improve stability and provide redundancy against mechanical failure or orca strikes.0:28 By retracting both boards, the vessel eliminates the external rudder surface that orcas typically target.1:28 Steering is achieved by lowering one board to create the necessary lateral force, a technique facilitated by the boat's inherent balance.1:39 This design addresses a 2018 failure during a passage toward Madeira, where thermal expansion in a carbon fiber steering tube seized the rudder mechanism in warm weather.2:20 Cooling the tube with water restored steering, but the incident necessitated waiting for cooler morning temperatures to maneuver into Porto Santo.3:03 The new configuration also incorporates dihedron sails to maintain a stable course in heavy weather.0:47 Beyond the steering system, the upcoming build replaces a cramped cabin layout that previously hindered movement between hatches and featured an obstructive forward bulkhead.5:08
