Wat a fantastic narration my friend. And of a fantastic group of ideas!

Thanks for a great description of this large wingmast. To those asking how to depower or heave to, a symmetrical airfoil has extremely low drag. To depower, simply (drop all sails) and point the wing straight into the wind. To heave to, have the wingmast and a foresail at different angles to he wind, or put the hull and wing at different angles to the wind.

Thanks also for a superb engineering analysis of the hull and boat in general.

Incredible but extreme design. Going fast is what’s all about. But what about slowing down when seaconditions require it ?

Fantastic. But the wavepiercing bow was invented a very long time ago allready. See the Tornado-class !!

How is it that this is the first time I've heard of this design? That cat looks incredible!

This is a tacitly beautifully structured, majestically designed, elegant, graceful catamaran. The wise gentleman narrating this video should be heartily congratulated for his emotional and touching choice of words, which includes a lot of practical engineering functions. His soul and spirit are all contained in his physical, practical, long experience.
All I can say about this Hybrid wing, is that it is very efficient, but it could be a little inconvenient on some occasions, and I shall point out that, THE MASTHEAD CENTRAL SPINDLE/ SHAFT IN THAT THREE WAY ANCHORING TOP UNIT, PERMITTING THE WING TO ROTATE, MUST BE VERY STRONG INDEED as that, effectively cantilevered mastheaded fitting, is introducing a heavy bending load, on both the spindle and the upper part of the D shaped leading edge section.
