New Boat Design: "Velocity"

He does create a lot of fascinating concepts~

 

It was no accident that Gentry's last attempt to wrest the record back from Don's "Destriero" was based on a fairly large SES. The SES was chosen as the platform with the most potential to take the record, out of all other options he had considered.

Fully funded and well underway at the time of his accident, the project ended after Tom passed away and I've not seen anyone else making a serious attempt to replicate the effort. It requires huge sums of money to do, and quite unlike the Hales Trophy winners produced by Incat, there is little use for such a vessel after the run is over.

The "Gentry Eagle", "Destriero" and the uncompleted Gentry SES had one thing very much in common; they were floating fuel tanks with engines. Common to each was a moderately high speed upon departure and an extremely high speed attained as the voyage neared its end and the tanks close to empty. Quite a different operating "profile" as compared to the Incats, for example.

 

So what do you think of this one?

Another tip of the hat to the work of Nigel Irens.

 

I can't help but like it....Nigel's credibility a key factor in that.

 

Do you know the length and (departure) displacement of that proposed SES?

 

I couldn't find Nigel Iren's name anywhere on that site.

Again - they talk about challenging record breaking with utter confidence. "The existing record will be beat by over 20 hours". "the center piece of the boatshow" and yet all they have is a 3D visualization which is pure illustration. Its clear the render is not of an engineering model.

I could do better than that in terms of scifi-3D, maybe I should start a money collection of my own. Can I get a few headshots from you experienced NA guys so I can have a reputable roster to support my Double Over Reactive Keel ship - in short: DORK. Its super fast and economical, oh yeah and very smooth ride. And its green too. I can't tell too much of the concept.

 

He's not involved but he is the one that originally proved the concept (iLAN Voyager) which has become an established standard for many power-Trimarans designs.

I'm on board.

I'd really have to go back and dig Leo and I was never involved directly in that project, although it was discussed that we might be at some point, to assist with the air cushion control system. As I recall, she was quite large in terms of LOA, at around 70 meters, although with an unusual bow design that extended well past the forward cushion seal boundary. LOA alone would put the craft in the 700 ton FLD (departure load) range, I would guess.

Prof. McKesson was very involved in the project, acting as the principle NA for the SES side of the technology. Per'aps Chris would drop in and regale us with some tales and further details.

 

Thanks, Bill.
I'd expect it to be about 70m too. I played around with a 76m 1200t design a while ago which would probably get the distance at about 55-60knots. I doubt it could make it at 75 knots though. If I was trying now, I'd look at a split-cushion arrangement.
