Anybody notice the 10' beam?

My 30' Willard has a 10' beam.

I think the beam explains the displacement question.

With an aspect ratio of 5-1 .. 3 hp per ton may/will be perfectly adequate.

Find some other boats w the same AR, disp and hull type/shape and compare their power and performance.

It's easy to fall into the overpower trap.

And if your beam and disp numbers are right and if the hull is in fact a FULL disp hull 100hp would be WAY overpowered. Another factor that is a part of this is how much fish will the boat be required to pack? Ice or other loads. Is the 10 ton disp # with full load?

I hope TAD sees this thread.
