When I started building this over 6 years ago, from the plans I brought, I built the 1st bow rib, completed it and
was getting ready to start the 2nd rib.
At that time, I knew I wanted a big OB on this, that's when YOUR question/comment hit me. "This boat will
not hold
that kind a weight." Researching the weight, anywhere between 400-600lbs for a 200-250hp OB. Not good!
So I closed up the garage, took the plans to my computer/CAD and drew this tunnel hull to scale.
Now having tunnel profile I can now calculate the square footage, and run the buoyancy formula.
We all know if the
weight of the displaced water, weights more then the total weight of the boat (with everything on it and in it), it will float.
Knowing what weight I needed, I increased the profile until I got the numbers that were in my favor, + a little more for safety.
I ran those numbers many times and also had a friend @ work run them too.
So, its not to heavy, it will float, hp wise to big??? Maybe, but I don't have to run it WOT 100% of the time either.
The tunnel is true to the plans, only the sponsors have been modified with a larger abeam.
How well will it preform? I have no idea. But we will soon find out.
Oh and my OB has a 25"mid..that all in another post here,

Thanks for your input.
