Please knock down stupid idea

[sub]

i think it ould work you just need to get past the fluid dinamics part, i my self am in the proses of building a craft that needs engines like the ones you are describing.

Gotta admit, ducks really suck on anything solid.
I'm curious as to the design philosophy behind that little grey wavepiercer there. Very neat idea. Should be much nicer in big seas than a planing hull.
Love the SeaPhantom prototype there.... time to start saving my pennies and dimes Really needs the helicopter-style turbine, I think.... can't wait to see the performance numbers on the production version!

You might have a look at these hull shapes as well;

Sea Knife:

1. Field of the Invention
The present invention is directed to a high speed boat 1 which does not slam or pound waves but cuts through them to ride smoothly at high speed even in rough seas.

That's really cool, but one would think sooner or later one would become airborn and come down hard cutting down deep in the water. I suppose this is why the Sea knife has a aircraft carrier type flanged top deck so it will not become a submarine.

Brian, do you know of anyother type craft besides RIB's and Hovercraft that prevent slam or pounding of waves using a soft material or inflated blatter/air spring/air cushion?

I'm thinking there are several alternate ways to deal with water/bow impact.

A: Slice it

B; Plane on it

C: Cushion it

D: Ride above it/fly

My perception and direction of goals regards hovercraft; which can cushion the blow of waves and in fair weather ride above the water surface. However as far as I know one has never really sliced the water with an ACV (Air Cushion vehicle).

Doesn't really have anything to do with this thread, other than the talk about the turbine reminded me: http://www.nyethermodynamics.com/

Take a look at the vids for Squirt 2.

How about this turbine powered RIB tender, http://www.yachtforums.com/forums/12004-post40.html
