Thread: If you had your choice of a "Go Fast" boat......

I want that new boat by that new company that has a suspended interior or whatever you call it...

That thing is badass and I want it. I can't seem to find the link but I swear I saw it on this site... anyone know what my forgetful self is talking about?

Statement Marine.

Uses airbags to seperate the cockpit from the Hull.. "THE" latest technology in fiberglass development since the addition of steps (in my opinion)

...and im VERY excited to see their new 50' cat, by the way.. Rounded interior tunnel sides instead of flat with spray strakes. Should be interesting!

Sorry for all the random posts. Cant seem to get the "edit" button to work today..

Can you explain to a layman like myself the benefit of such a design?

Where to start.. Ok, the basics of catamaran design. The more air you compress into the tunnel, the higher "lift" you will achieve. More lift, equals less resistance. Less resistance equals less drag and equivocates to higher MPH. So, to get more lift you need more air compression. You can get that one of two ways.

A.) Either go faster and feed more air to the existing tunnel *usually 4-6' wide
B.) create a wider tunnel to allow more air at the same speeds to provide lift.

well for the boat to be legal to transport on the highway, it will need to be NO WIDER that 14' (and thats on a TILT trailer!). So you cant have a 15' wide tunnel on a 44' boat and expect to have a user-friendly boat. So what statement has done, is increase the tunnel width by allowing reliefs and voids in the tunnel sides. Which also direct air down and to the sides to help lift the heavier aft end of the boat.

Now, with that said, you could have a 12' wide boat with a 11' wide tunnel but then your sponsons are only going to be about 6" wide each. NO fiberglass, carbon fiber or kevlar is going to be able to withstand the 10k# of boat forcing a 6" wide sponson through 8' waves at 140mph. So Statement has kept the tunnel width at the water the same as the average cat, to allow wider, stronger sponsons. The voids and recesses in the tunnel allow more air in while maintaining a stronger deck, wide sponsons and the like.. The boat hasnt hit the water yet (to my knowledge, I could be wrong though) so there may be quite a bit of sanding and sawing left to do to make sure the boat is going to ride the way it say it will on CAD..

holy great explanation batman! Makes sense to me! Seems like boat design has been fairly stagnant for the past couple of decades and people are really starting to make leaps and bounds in the design and technology just now.

Should be a cool project to watch unfold.
