@ it’s magic 😀. A 5 sided box is quite flimsy but add side 6 and you have a torsion box. It’s stiff like a guitar body. Yes, it adds triangulation. You could cut the middle 1/3 of every side and it would still be stiff. That’s why my mast step box did not break. It has 6 sides with a few interior holes.
Are those holes aiming draing flooding waters resulting from choppy waves, or, do you also expect them to drain water say from a puncture at the bottom?
The holes will be to let water that came over the sides drain out. So basically now, because both the front and back halves of the boat will be self draining, it’s more like a SUP with side rails. I could take this to the beach and cut through the surf without sinking or filling up with water.

Isn’t that foam extruded poly styrene? I thought expanded poly styrene was the white stuff that looks like little beads.
Extruded, yes, sorry.
@ that foam really stiffened it up. I guess it acts like a bunch of little
I-beams or box beams.

Also, I don’t expect any water to ever reach the inside cavity once I prime and paint it.
