It's asking a lot, although probably not too much. Just treat it gently,
and expect that, in a serious collision with a rock, that you will reflect
happily on how you wore your PFD that day.
4mm okoume is awfully thin for that boat. That's about as thin as
one can get away with for ply lapstrake canoes, and those boats have
a lot more shape to them; compound curves and double-thickness laps
make for a much stiffer shell. The long, skinny, and squarish
pirogue doesn't have much curve to the panels, and I suspect it'd be
awfully floppy with 4mm. Okoume isn't that strong, also. Maybe with
careful reinforcement at the chine and gunwale, and an additional
frame or two? 1/4"-6mm, at least on the bottom, would be a better
bet, IMHO.

D'oh! I meant 3/16" thick occume down there,

Chris,

Thanks for the reply. I didn't realize that that was the structure
of the panel, but I did know that poplar is not the most durable
wood.

Do you think that one could get away with 3/8" (4mm) thick occume for
a small, flatwater boat such as the 16' Pirogue? Or am I asking too
much?

TIA,

Umm, I wouldn't.

(1) Poplar is rot-prone.
(2) Most importantly, bending ply has all its grain in one direction, as
compared to most plywood, with grain crossing at 90 degrees for each glue
line.

This makes it a very different building material, and I believe that it
would have so little stiffness, that the boat would not be able to keep
its shape.

You want light? Spend a little extra and buy gaboon or occume.
You won't be sorry.

Boulter Plywood lists Italian ply and also "Wacky Wood" ply, both listed as
very flexible the Italian ply is listed as available in "long grain" or
"short grain", I guess sort of like rice. Only the short grain product is
good for making rice pudding, I don't know what this implies for building or
cooking with the short-grain ply.

Hardwood as a marine plywood weighing 15 lb per 1/4" sheet. All I can
find on the Web is that it is also called "bending ply" and "Lite-
Ply", and seems to be poplar-cored. It seems like just the stuff for
a Pirogue or Car Topper that could be lifted gracefully to the roof
racks by an aging baby boomer, assuming it is appropriate for these
applications,
