It might not be universally applicable: the catamaran is very tall, and that spider-like thing is flatter, but enormous. And the cost doesn't bear thinking about. But the chase boats hadn't a hope of keeping up with either of them: the difference in ride and the way they react to the waves compared to a traditional boat is remarkable.

Thanks for posting that. Very interesting.

Looks very interesting, however I see when anything goes wrong on the suspension !!

I guess exposed hydraulic rams and salt water would take its toll. However the trim and tilt on the back of outboards seems to work pretty well.
I liked the way the boat stayed still nudged up to the jetty - very cool.

The Cost!...Forces exerted by a Knarley Sea and the the Corrosion implications,pluss the lack of Hydro Dynamics in anthing but ideal conditions,will soon consign that to the "It seemed a good idea at the time" Scrap Heap IMO.
Bloody lot of trouble to go too to iron out a few Bumps!

I was asked to look at an experimental UK boat a couple of years ago that the entire inside of the boat was mounted on mini shock absorbers. No matter what the hull did the cabin and deck did something else. It needed perfecting but it had a lot of potential. Not sure if they are still in business but if they are they could put all the suspension seat manufacturers out of business. Alan P

Considering the legal requirements for shock protection that you have over there and I suspect we'll see over here I wouldn't be so quick to write it off.

Their web page says they are an R&D company. That's got to start somewhere. Obviously not right to consumer boats but I can see commercial applications. It might be cheaper than a dozen or two suspension seats.

It appears to be an actively controlled rather than a passive mechanical system — imagine the cost of two dozen electronically-controlled suspension seats!

It looks more effective as well: there's a lot more travel in the suspension in the video than you'd be able to build into a seat. You can't completely remove the vertical shock of a 4ft lump with only 1ft of seat travel, but you could do it with 4ft of cabin travel.

I guess for military use, the platform would be steady at speed for the use of a gun emplacement. Similar to a tank moving at speed and using the same gyroscope method where the barrel stays still - lethal. Would make pirates of the high seas take notice with that coming at you flat out, 'guns a blazing'

School boy stuff

Had a look over the Yellow one in the images at Seawork last year.

Interesting concept, and looked like quite a ride whilst it was out on the water doing demonstration runs.
