Which layup is safer? It seems sometimes a boat's ability to flex would prevent catostrophic failure. Is this true? I guess this question is more for the builders.

Aloha Salt,
You do NOT want a boat to flex much, that encourages hairline fractures, opens the seams etc. which eventually promotes total failure. I don't think any boat builder intentionally builds a "flexible" canoe, if so, we are going into the realm of ROTOmolded plastic Kayaks where they are really flexible and tough. We have explored doing such canoes but I don't think our boys and girls would want such a heavy canoe in rotomolded plastic.
We use carbon / kevlar weave also on the inside for PUNCTURE resistance but our additional stiffness comes from the 3 mil. foam core Also HOW you cure the lamination canoe makes a big difference.
And a stiff canoe sure makes it a lot nice to carve down a big bump.
In metallurgy bending resistance is preferred to prevent sudden total failure. Hope it answers some of your questions.
