Neat idea. I'd be interested in learning more about how it captures/harnesses the wind.

The article says that the hull shape itself channels the wind like a sail. Which means that it might gain some benefit going upwind, but it will obviously do nothing at all downwind, and might even be a detriment in a crosswind. Meanwhile it will cost more to build than the average container ship, and looks like it won't carry nearly as many containers.

I suspect this announcement is mostly a publicity stunt. I will be surprised if a real ship ever gets built. Of course, if they can actually make something like this feasible, then more power to them, and I hope they end up making more money than they know what to do with. But I have my doubts.

Re: Cargo Ship To Use Its Own Hull To Sail

I'm very skeptical of the claims that it will save 60% on fuel. Seems like more gimmick than engineering to me. If only sailing were that simple!

Is this also the man with no pants by any chance?

Like the ship with a spinnaker. Never happened.

Air draft is so high too it would be restricted to outer ports, where roro's like inner ports.

Re: Cargo Ship To Use Its Own Hull To Sail

From the drawings, these appear to be RoRo boats, something that has been phased out in the larger, modern, container carriers. I doubt seriously that they would be welcomed in many ports that are designed for rapid container operations.
Both drawings show very narrow vessels with extremely high freeboard, seemingly not particularly seaworthy designs, with poor visibility from the bridge.
I guess we'll see, but it's my guess this idea needs a bit of reworking.

I'd like to see the crew reef in a blow.

Bunker and current electro diesel marine tech is far more efficient than grandiose picture implies and 14 knots aint gonna attract support from the market.. The newer boats are huge and move alot faster.....I think the entrepreneur has sent up a balloon to attract development money. Maybe he isnt as flush as folks think....

Re: Cargo Ship To Use Its Own Hull To Sail

Aren't car carriers still RoRo ? Whenever we sail up/down the NSW coasts we certainly see plenty of them and they look every bit as top heavy as this thing. For mine it doesn't seem to be a design that is aimed at the container market, rather as a vehicle carrier.

Anywho, its only a design exercise at this stage.
