Layout question

[Sal]

Thanks. Any thoughts on the spacing issue, one support near the bow, another at the casting deck and the last at the aft seats. Obvious concern is the span between the casting deck and the seats. But I think this layout would maybe prevent killing toes. I was thinking about running a horizontal brace between those two vertical posts, and run it up somewhat high so it is kind of hidden under the gunnel. Any thoughts? Thanks.

That inner liner adds a lot of torsional stiffness to the hull which will be lost when you remove the solid inner walls, but I think the best way to restore that is to core the hull. That will uniformly stiffen the entire hull without creating local hard spots and the resulting stress concentrations that you'll get with local ribs. Might cost a bit more in materials, and the ribs would probably work ok since the hulls are so overbuilt to begin with, but the cored hull would be structurally superior in terms of torsional stiffness and rigidity.
