: I assume you mean PVA rather than PVC.

: Logic tells me that as a good PVA joint is usually stronger than
: the timber itself and as the joints are encapsulated in glass
: and epoxy, there should not be a problem.

: Experience tells me exactly the same thing. None of the seven
: kayaks I have built that way have had any problems.

: The coaming is best reinforced with extra glass, not different
: glue.

Actually I switch back and forth between the two glues when building a boat, the PVA works fine as long as the joints are tight and there's a reasonable way to clamp them. Epoxy is a great gap filler so if the joints might not be perfect it's a good choice and takes little clamping pressure to work so if it's difficult to clamp I'll again use it, otherwise the PVA glue is so much easier and faster too.
