New Build Episode 2 Paul Madden examines wind-assisted propulsion options

Growing up sailing with my dad, he always referred to motor-boats as 'stink-pots'. Motor-boaters, I am told, refer to sailors as 'rag-baggers' due to their proclivity to bag their sails at the end of the day, often before even having cocktails(!) However, the time has come for everyone to take wind-power seriously, as perhaps the most viable solution for lessening carbon emissions of all ocean-going vessels, private and commercial.
Wind-assisted propulsion system (WAPS) technologies have gained significant attention in the shipping industry as a means of reducing fuel consumption and emissions. These technologies harness the power of wind to supplement the propulsion of a vessel by generation of aerodynamic forces.
And now there are several new sail-assist technologies that have been successfully deployed on large commercial vessels- achieving results in fuel efficiencies that are quantifiable.
For our new build, we want a proven sail-assist technology that is readily adaptable for our specific mission and vessel profile. We need to consider, amongst many criteria - size and weight vs propulsion delivery, will the rig fold-down, can it be fully reefed in the event of a power failure without putting the crew at-risk, is there a service and maintenance program from the manufacturer to support us.
Hopefully, this video will shed some light on this highly important component of our new-build process, and maritime industry developments in general.

As always, it was a fascinating and outstanding video.

Thanks Paul!

Hope to see her full exterior and interior design, bet she will be pretty 😍

[@danieldezauche8223]

Thanks for the content. Very informative and well done.

Good videos as always, very intresting :)

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.

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.

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.
