magnetize the water to reduce the drag maybe? Effect of magnetic field on the physical properties of water Author links open overlay panelYoukai Wang a, Huinan Wei a b, Zhuangwen Li a

What's amazing is how these genius people can design these boats and when it comes to talking and explaining them they are the worst speakers.

Not forgetting the SY Sunbeam Owned by the Brassey family They undertook a world cruise. Lady Brassey ( Normanhurst Estates in East Sussex ) wrote a book about their journey.. Voyage in the Sunbeam.They departed from Hastings in great fanfare with a Navy Reserves Gun Salute.There's an engineering model in the museum at Hastings. My Grandfather John Anderson was the Chief Engineer. He was from Auchterarder studied in Glasgow and part of his training at the North British Locomotive works.. He gained his Chief Engineers Certificate at 21.

Mahdad for me had the most compelling argument. A big step is just looking at ways to stop wastage of energy. Even if the solution need to look at a combined solution that splits the propulsion from the hotel load.

Great opportunity to market the reduction in the carbon footprint of a new built compared the refit. perhaps incorporating some of the lessons learned from the new built into this one. The big deck space also creates great options for modular configurations based on the owners requirements for the specific expedition. Just so much that can be done. Cant wait to see the final product.

Hah, enjoyed the humour.

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.

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.

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

As always, it was a fascinating and outstanding video.

As someone that was a proponent of Flextern sails, primarily because I watched a RUclips 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 RUclipsrs video tomsee if rotary sails zmd Flextern, which may nkt be the right spelling ....hmmmm. More research is needed.

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.

Thanks for the content. Very informative and well done.

Отличный видеролик. Интересная информация. Спасибо

Thanks Paul!

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.

Hi Paul, I have been reviewing the alternative issues for the yachting industry and I have found that HVO (Hydrlized Vegetable Oils), is the best alternative is the HVO. It shows that you have a 90% clean burning and can use it in almost all diesel engines. I DON'T UNDERSTAND WHY THE INDUSTRY IS MAKING SUCH A FUSS ON HYDROGEN OR ESTHANOL WHICH DOES NOT CONSIDER THE COST OF CHANGING ENGINES ON ALMOST 99% OF EXISTING VESSELS!! Additionally, the whole production of vegetable oils is at minimum carbon neutral. The current cost of a liter of HVO is 15% higher than diesel. I would love to hear your thoughts regarding the issue.

Love the idea. How much for a brand new ice classed osv with diesel electric and retractable fin stabilizers. Finished to mega yacht standards. 220 ft? Class bridge ect ty keep posting ty

If I was a benevolent billionaire I'd outfit a dozen of these vessels as marine research ships that could include 20 or 30 students and kids and make them available to countries that can't usually afford them. Teach them the realities as opposed to the climate doom stuff. I guess that means everywhere except Western countries at present, unfortunately.

Do you take the DP2 system out altogether or simply modernise it? Is DP really no use on a fancy superyacht?

This is very cool, but what is the total coat? And I've never gotten an answer to the parts taken off and sold. Is the money received from the sale of those items no longer needed, is that money applied towards the build or is it splt for the removal, but would have been removed anyways, but is it just money to the shipyard?

keep doing the updates!

The 90m OSV would be a great toys

I’m very excited to see the different stages of this conversion all the way to completion! So far so good.😊

You got a lot done! Job job!!!

Very interesting-

You listed the owner's requirements in an earlier video. Somehow the combination of meeting those requirements, and possibly some financial advantage, tipped the scale in favor of conversion over purchase of a conventional boat. How close was the owner to going with a traditional purchase?

I like it. Is all of the design work complete? Do you worry about political and currency instability in Turkey?

I'm guessing it's a security/privacy issue, but I'd love to see the plans for the new vessel and see what she's going to become!

I get having a parallel hybrid system on a leisure yacht and even a military vessel so you can be silent and not leave residues for short periods of time. But merchant vessels? Every time you convert energy you incur losses. That is exactly what shipping lines want to eliminate.

Is she ice classed?

Asking price? Is there room for a sick bay?

1- For my sailing yacht, I want autonomy---the sails plus onboard generation of hydrogen or ammonia for autonomy. Ammonia is less volatile than hydrogen, so an ammonia internal combustion engine or fuel cell. And electric power generated under sail, wind, or Sun to produce hydrogen/ ammonia. I don't like Lithium batteries. On a sailing yacht, I only need power to propel through the doldrums 2- For my motor yacht, I want economy for a yacht large enough to carry a twin-turbine helicopter and a small submarine, so nuclear power. 3- Ammonia/hydrogen, sails, and renewable electric power aren't as practical as nuclear power for large yachts, whereas nuclear isn't practical for small yachts.

is this a new build or a refit of an osv ?

Thanks Paul!

The most effective and efficient propulsion fuel in the Marine industry is diesel. They can not extinguish an EV car battery fire on land I don’t think that I would like to be in the middle of the Atlantic with a battery fire! And as you pointed out hydrogen has is its risks as well.

It would sure be nice to see some updates from the ships that you have brokered.. very interesting panel. 💡

Could this woman be more wrong :-) in her knowledge timeline in the video 11.55 min to 12.10 min She claims The reason why Elon Musk has become one of the richest people in the world is that he has sold his right to pollute with his cars, but since electric cars do not pollute (while driving) like petrol and diesel. Since the EU has demanded that cars pollute less, they have also created dishes so that different car manufacturers can add up their pollution and save their companies. and when companies like Tesla are welcome in these projects it is because together they pollute less with Tesla in the group And Elon was smart to sell his (lack of pollution) to others car manufacturers, And the EU itself has approved this. And there are several car manufacturers who had to close their factories without tesla included in the calculation Elon Musk has afterwards in an Annual Shareholder Meeting said that he is not happy about it but when he got offered FCA gave up to $750 million to Tesla (for nothing) and he has received offers several times and made agreements Elon Musk is good for over 200 Billion, so 750M is not why he is one of the world's richest. Tesla Cars are approx. Worth $572.11 trillion by 2024 And she claims that the cleanest energy is the energy we don't use I guess it's the same as saying The least polluting cities in the world are the ones that only found in our Fantasy What an attitude 😞

Some actual fuels may not have an actual carbon atom in them but how about the trail from mine to manufacture, both the machinery and the process. Real pollution is pollution. CO2 is the building block of everything and the greening earth shows it. These guys are professionals but they are pandering to the myth. Except maybe the lady. Her head is permanently in an ideological cloud.

With all the talking I’m hearing in the audience is anyone listening?

Thanks Paul!

At what point does it stop being a yacht and becoming a ship

I have invented a hydro-electric propulsion feed system for boats and ships, as well as a bow hull modification. I will not release until 15 are built and in total use.

Stupid question: could these be converted into military like ships?

This was fabulous. I was bored on a Caribbean cruise once & took a ‘behind the scenes tour’ of the ship; explored top/bottom, stem to stern. I enjoyed that more than the cruise. lol.

Brilliant yacht,thankyou and what is its sale price?

Is there a full video and technical write up available for this vessel?

I would also want the following survival gear on all of my yachts, aircraft, and helicopter. Survival Gear: Lifeboats, life jackets, buoyant platforms and life sustenance accessories: A- Lifeboats: A spherical buoyant shape(just like a ball), so it is resistant to wind and waves. It can be made from fiberglass, aluminum or titanium. Fiber glass is light, but can break, whereas aluminum can corrode with currents. 1- Keel with anhedral wings (just like the shape of the Harrier jet-aircraft) beneath the life-sphere to prevent it from overturning/flipping. The wing-shaped keel would serve as an anchor when the life-sphere is motionless to prevent its rolling, while it will help the life-sphere plane or even hydrofoil at higher speeds, when the life-sphere is propelled. A squall or a breaking-wave should fall on the anhedral (aircraft-like) keel, from the top, to anchor it and to prevent it from capsizing. Waves approaching it from the front, would lift it up(depending on the angle-of-attack of the wing), just like an aircraft, so it effortlessly surfs the waves and doesn't fight them. Waves approaching from behind would push the tail of the anhedral(Harrier aircraft-like) keel down, to lift the wings up. However if the angle-of-attack of the wings is too abrupt, it could cause the life-sphere to roll-over/capsize because the escape hatches can never be perfectly sealed. a- Even though a sphere can self-right or can have a gyro inside it to always keep the occupants facing upwards, the escape hatches could still leak, so it is important that this shape doesn't roll. b- One could also extend an inflatable water-tank beneath the life-sphere, at a greater depth, which would fill with sea water and act as a deep keel or an anchor to further prevent rolling. c- We could also construct partially perforated wings around the sphere to resist rolling and flipping/capsizing. 2- Solar-Still: One could add a spherical solar-still made from transparent plastic along the entire surface of the sphere. This would have a dark insulated chamber beneath it where the vapor would condense into purified water. This chamber could use solar PV-cells on the outside to generate electricity and to also shield the condensed water from the Sun. One could use capillarity to have the outer chamber of the solar-still fill itself up, or we could fill it up manually. The Sun will naturally heat the water into vapor in the outer chamber, which will condense into the inner chamber. 3- Solar Panels, Regenerative Props, and a Wind Turbine: These will provide the raft with power to propel itself and to also operate the HF and VHF radios, satellite phones and beacons, a fan, a heater, and perhaps even a dehumidifier(to condense vapor into water). We could also equip this with a solar cooker/stove that could also run on electricity. Food would have to come from the fish and sea life which the occupants hunt, whereas the salt will come from sea water, which can even fight germs. The vitamins would have to come from the livers of whatever they hunt. 4- Thermal Battery: The water heated by the Sun during the day could also be used to keep the craft warm at night. 5- An Electric Motor and a Small Sail: These would be the primary and secondary sources of propulsion. The life-sphere will use both solar and wind power during the day, and wind or regenerative turbine at night. It would use the sail if the motor fails to function. 6- A Stirling Engine: The prop could also be coupled to a Stirling engine, using a parabolic reflector or a magnifying glass to heat the base. This isn't very practical, but one could look into it. 7- Aluminum Foil: Part of the life-sphere not covered with the solar-still and solar panels can be covered with an aluminum foil, so it naturally reflects light for search teams to spot it. I would also want small, hollowed, polished stainless or chrome plated floating balls for reflectors. 8- Weapons: A Taurus Judge revolver, long-barrel Tavor 7, a few cross bows, a few spears, and a few knives: The Taurus Judge can fire 0.45 Cal long-cartridge (which could even kill a shark that has breached the water, and everything else), and also 410 shells (which could help hunt and even shoot flares at night). The cross-bow could serve as a harpoon, and the spears and knives mean you'll never run out of ammo to defend yourself. 9- Inflatable canoes, kayaks, life jackets, and large Styrofoam pads: These would provide flotation and transportation even in the event of the life-sphere sinking for some unimaginable silly reason. 10- Navigation: A solar, waterproof, and floating satellite phone/smartphone/GPS device; waterproof or plastic floating map; and a floating compass, Octant and Sextant. B- Aircraft Survival Gear: A maneuverable rectangular parachute, with flexible solar covering and a small electric motor to fly it, like a slow-speed aircraft. You'd also need inflatable/light-weight versions of some of the other survival gear designed for the yacht.
