Not much pro there.

The bed liner material will not be cheap. The sheet will need to be
(roughly) twice as thick as ply of the same strength for your purposes
and is really dense. It hates water. Something will leak.

You would be far better off with well-painted exterior ply. It
probably won't cost much more either.

If you are getting down to the chipboard sort of level when building
boats, then expect failure to be the norm.

I plan to build a 8 x 16 ft. barge using 3/8 osb sheeting and covering it
inside and out with a spray on bed liner material. Any pro or con comments
would be appreciated.

I wouldn't even waste the time or money doing it in such a fool hardy
way.... OSB? No way!

I have read enough to scrap this idea, will go with exterior grade plywood.
Thanks

As was said, a lot depends on your usage, but 3/8" of anything for a
16 x 8 barge is probably not enough. It _might_ be OK with full
fibreglass sheathing, both sides. Might. A barge is by nature of its
shape a fairly weak structure, and the skin is very flat and prone to
bending. You will at least need lots of frames.

To give you a (rough) idea

http://www.duckboats.net/dewald1.htm

Shows a 13' by 5' boat using 3/8" ply. You would need to step up from
that quite a bit. His boat has chines and a keel, and the shape will
stiffen it.

Oh. And don't listen to his bit about glass mat being stronger faster.
Cloth is way stronger per weight. Mat was used a lot to bulk up boats
that were glass only. It is resin-rich and not strong.

Also try http://www.devlinboat.com/dcduckboats.htm. They use sheathed
1/2" for a similar sized boat to yours. BUt these are tough boats, for
choppy conditions.

I have never hunted a duck! This just seemed the sort of size and
materials you were looking at.

You'll not be building a boat, you'll be building a sink...
