WIND POWER The wing sails are almost twice the he
ight of those on the largest sailing vessels of today. Regular sailboats normally use the 30 metres of atmosphere closest to the water, and that’s basically where Oceanbird starts to sail. No part of its wing sail is lower than 30 metres, using a piece of the boundary layer of the ocean that basically hasn’t been used before. THE HULL Normally when optimizing a hull for a cargo ship, the number one priority is to minimize the drag, but with Oceanbird the design also has to deal with the big side forces, generated by the wing rig. A number of moveable fins compensate for the side forces so the hull goes straight through the water instead of having a side slip or a drift angle. Cutty Sark 47 metres
