: Most okoume 4mm ply is three ply, the grain on the outside plies
: usually runs the length of the sheets so there is only one ply
: running across the sheet to resist the bending moment. All
: plywood is stronger in bending one direction than in the
: opposite direction, this was my concern.

Oops! Forgot that. I redid the calculation, the ply has only 80% of the strength of the ribs, worse once the contribution of the planking is taken into account but it's starting to get complicated. Although the hull is complete only to the top of the bilges it is very stiff and there's no way to get visible flexing in the bottom plank so I am sure it will be OK, though. Dora, my first successful canoe, only has 3mm planks on a 4mm bottom and she is still going strong without glassing.
