Destroyer, Ever consider making some limber holes to allow the water to drain from all compartments?

It is, indeed, funny math. You have to conceptualize that water is buoyant and is actually pushing up on the foam. I think it's Newtons 2nd law that gives us the equations.. I'll have to look it up.

In all cases, Spareparts made the comment that he:

I liked the idea so much that in one of my followup posts I said that

Truthfully I never knew they were called limber holes, but your idea is sound and exactly what I was planning to do. I plan on drilling 3/4" holes at the very bottom of each compartment and then cementing PVC pipe into the holes to make drains into the bilge area. If anyone has a reason to use a different size for the pipe I'd be greatful if they would tell me.
