Hey if you ever get more inof how it does in testing post back on this thread. Pretty nifty hull design to say the least and not to mention the stealth panels above the water line..

Way cool! I love carbon fiber anything. Here's some pieces from the links on the page:

"Air plenums
As highlighted above, the M-hull works by recapturing bow wave energy in air plenums. Air and water are trapped by the planing tunnels, and forced aft, under increasing pressure, as the tunnel ceiling slopes down to the waterline. This creates what M Ship describes as an ‘aeroplaning’ surface, which provides lift with reduced friction drag, thereby increasing propulsion efficiency.

The air capture mechanism of the air plenums and the hull geometry also have a number of other advantages, including reduced drag. The M-hull uses the spiraling action of the bow wave to entrap air in the boundary layer and ‘lubricate’ the hull. This high-pressure air-water mixture is then automatically pumped under the hull, creating a low-viscosity boundary layer, the result being a significant reduction in the friction drag.

The energy contained in the bow wave spiral is also converted into vertical lift. The accelerated volume of the wave created by the central displacement section deflected downwards by the concave shape of the planing tunnel ceiling and the rigid skirts, to create a ‘momentum transfer’ that helps lift the hull out of the water. This lift supplements the planing and displacement support of the vessel, reducing overall drag.
*
The hydrodynamic characteristics of the M-hull also contribute significantly to the reduction of the craft’s acoustic signature, claims M Ship. The M-hull geometry is designed to capture the bow wave, which is a significant component of the wave pattern around a ship. By capturing the bow wave, the vapour/fluid flow field passively dampens the visible and acoustic signature of the vessel. The stern wake energy that moves away from the ship through the momentum transfer process of water molecules is inhibited by the presence of millions of captured air bubbles under and trailing the ship. In the same way, noise from the vessel’s passage and its machinery is reduced."

4x1650hp

Navy officials were particularly encouraged by tests of a 38-foot aluminum boat with an M-hull. While headed into the wind, the prototype actually increased its speed by 15 percent without adjusting the throttle, Glaros said.
*
Among other things, Glaros said, the venture represents a test of carbon composite construction techniques.

"Can we take a design and lay the fiber accurately enough to make sure there are no gaps or weaknesses," he said.

With guidance from SP Systems, a British subcontractor that makes composite materials, the team developed techniques for making foam-core panels. The pieces are bonded together using epoxy and carbon fiber strips.

Definately a neat design. I'd love to see it run.

What speeds do they think? What class would it race in

Saw a jet version of that hull run on a Discovery Channel Maritime program. Said to run 65mph (or so) in mid-size seas. Stable platform for miliatary applications that can run closer to shore than current ships. Designed to house multiple pods on board (tractor trailer boxes) each filled with contents for different missions, like underwater recovers, seal teams, etc. The one on Discovery had a ramp drop from the rear, between the jets, that can launch a 38 foot RIB!

If interested, you can download a powerpoint presentation with specs here:

It's 32 Megs though.

It runs really well. We reached our target speed and then some so everyone is happy. 50 knot goal 53 knots so far.

Imagine, no bow lift when getting one plane. (Kinda hard to get bow lift when getting on plane with a 53 ton boat.)

It handles the seas really well off San Diego and it is a trip to ride in.

It was built with pre-preg and baked.

Wow. Very cool. So, I take it you're on the project team. It's one exciting new design, for sure.
