It seems to hold up very well for these:

But I always thoroughly coat it with epoxy and sometimes vacuum bag a layer
of glass on as well. Note the tortured shape, from 3 layers 3mm laminated
with rocker and bottom concave.

Nice springy "pop" like a snowboard. At 180lbs with frequent jumps to around
15', I haven't been able to break one or seen any signs of rot yet, even the
ones where I ground through to to bare wood riding over sand and (sometimes)
rocks.

Then again this is not an application where the wood is submerged for much
more than a few hours at a time.

Yes standard Baltic (actually Russian) birch is not even slightly water
resistant.

find is that it only has interior grade glue.... which I don't think

Are you sure you can't get 3mm baltic birch ply locally?
It seems to be very popular for making drawer bottoms. Cheap and strong
too.
I think 3mm should be flexible enough to cold mould the way you want.
