In @1988 I enjoyed the privilege of meeting Jacques Cousteau's son Phillipe Cousteau when he visited Melbourne Australia on Alcyone the Cousteau Research vessel. Alcyone was an incredible yacht that had two rotor sails.
I've been the greatest advocate of multihulls because you get a stable yacht with a wide beam, a very low drag, and a very shallow draft, but I personally would never buy one, mysel, since these most likely wouldn't outlast my own life. They are efficient, but could rupture under adverse conditions. A multihull with centerboards/daggerboards could even overcome the capsizing challenge. Take a look at the Independence Class trimaran and also at the Adastra trimaran if you want efficiency, but can settle for immortality.
Those wing sails look good for a wealthy yacht. The mast lowering facility will open up access under bridges. I could see the engineering and maintenance costs being frightening. I would love to see how it stacks up for commercial vessels both container and bulk. The two things I see are cargo space intrusion and vessel size limitations as in you'd be reversing the trend of fewer bigger more economical cargo vessels.
Wow.. It doesn't look like a cheap option but 350t fuel savings is a fantastic start for a return of investment. PS: Thanks for the conversion update last week Paul.
Azimuth electric propulsion with methane fueled fuel cells (and of course batteries), assisted with sails such as you propose, and a liberal splash of solar cells and other wind turbines where practical, could make for a ship with very little actual fuel usage compared to a conventional ship. If the yacht buyer were to invest in a pilot plant fabricating methane from solar power, pulling CO2 from the atmosphere, and build it big enough to create as much fuel as their yacht consumes, they could honestly proudly boast that their yacht is net zero.
As someone that was a proponent of Flextern sails, primarily because I watched a TH-cam video about them and thought they were cool, I had hopes they would win. A.thpugh in the video I watched, it was set in the 30's a d they didn't have rotary sails. The wind simply went around poles and that created a low pressure area in front that enab,ed the boat to save on fuel. But maybe I was wrong. But then Paul never responded to comments so mahbe he never rezd I was talking about Flectern sails and not rotary sails. I had even suggested them to Arksen for their 85 project and was told they were looking into it, but then I never heard anything back. I'll have to go bac, a d check outmthe other TH-camrs video tomsee if rotary sails zmd Flextern, which may nkt be the right spelling ....hmmmm. More research is needed.

Looking forward to the reports from the upcoming meeting
Отличный видеролик. Интересная информация. Спасибо
Thanks Paul!
Thanks for the content. Very informative and well done.
Hope to see her full exterior and interior design, bet she will be pretty 😍
Good videos as always, very intresting :)
As always, it was a fascinating and outstanding video.
