Default Longer is smoother

The lighter and stiffer the boat, the harsher the ride. That's physics.

The lighter and stiffer the boat, the faster the ride. That's physics too.

More physics: If two boats weigh the same, the longer and thinner one is smoother riding. Smoothness of ride increases by L/sqrt(L).

A dimensionless ratio of smoothness (vertical accelerations in waves):
32' = 5.65
40' = 6.32 = 14% lower vertical accelerations that a 32' boat
50' = 7.07 = 10% lower vertical accelerations than a 40' boat.

I knew all that and barely made it out of high school.

My dad use to build cars and he always said that if you make a car to light forit's class you can always add weight to it and the weight will be be where you want it.

In our case it was always as low to the ground as possible.

That is going to be one awesome boat when it's finished but I bet I couldn't even afford to insure it....LOL

That things gonna have a huge gas tank.
