Sorry to post it on RIB forum but you are experienced people here.
It is for motorboat but not RIB.
Friend of mine owns small business to set-up boats (he sold me new engine, mount it, hydraulics, electrics - AKU, everything). He makes also small 4,4m boats for fun and fishing:
Very solid, he uses kevlar mesh mats. He makes some solar powered cat's but it is not his project but order from some German company (they sell them to Dubai and German rental offices for restricted areas).
But he always want to make some unique boat I think so he has made model and form for speed boat hull (not exactly like legendary Hydrostream but similar size and better performance for small engines):
These are first test (this barrel is for displacement). He tested bottom hull only use 50 HP MERC and 13 and 14 props (he had not bigger ones during tests). Engine has been cut on both above 6400 RPM but purpose of the test was to check behavior not top speed.
It works like Concorde airplane. It fly above water surface. You seat like "in the middle of air". He tested with 3 persons and results was the same. The hull returns to this position after any maneuver or change speed.
Boat will have 4 cubic seats (driver, passenger behind driver and 2 seats on the back). ECO version will cost 5000 GBP hull only plus current price of MERC 50HP engine (or EVINRUDE 50). He is sure that "special" version can keep even 200HP. It's size id 485 cm length. I think that V angle is 22.
Why I ask about opinion. Do you see any potential customers for such kind boat ? It is fast, but for inland areas only I suppose.
Do not tell him but I'm a little skeptical.
Many thanks for share any opinion and thoughts.
Finish it is a financial challenge for him so I'm trying to stop him a little.
He have to make forms for console, top, ...
It be certified as D cat.
