1. Extremely well presented; would be nice to see more action shots sometime, but very well explained, enthusiastically. It must be the future. I remember meeting a multihull designer about 28 years ago, who was testing on Lake Mead with hulls that would leave hardly any wake.

2. Excellent review Jim. Quintessential info for those looking to get inform for the future. Many thanks

3. I enjoyed every minute of this presentation. Your charisma and attitude transcends generation boundaries.
   I hope to see more presentations from you in the future. Cheers

4. Enjoyed this video very much!

   Do you know if this wing can be put on a Sunreef 80?

5. WOW, this can truly be the future of sailing! But the mast is located way to near to the bow…

6. They got impressively close to properly endplating the mainsail without quite getting there.

7. Great concept!

8. This was awesome, thank you.

9. I just got to see it while working an aloft job in St Thomas in an adjacent slip and all I can say is it does not disappoint. I'd rather see it out underway here but looking down on it from next door was still exceptionally nice.

10. So, how do you heave to in heavy weather with the rigid wing? I get that it can freely rotate so but that's still got to affect stability in weather. Also, how easy is it to tent pole and/or capsize coming off the foils? I'm still waiting for the day a sailing cat on foils can cross an angry ocean.

11. 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.

12. the sail looks like a propeller.

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

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

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

16. 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.

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

18. Fantastic. 💚

19. Phenomenal

20. 我十分认同你对混合风帆的未来技术发展畅享！
