Polyurethane (Gorilla Glue), PVA (Titebond), and epoxy are all stronger than the wood, so the wood will break first--in a good joint.

For polyurethane, the joint has to be 100% perfect and well clamped or it will develop no strength. I wouldn't use it in a gunwale because the risk of failure is too high. PVA can tolerate a bit more slop in the joint. It actually has a little bit of gap-filling ability. If your mating surfaces are sloppy or you're worried about them, use epoxy. If you've got a good joint, you won't need any reinforcement.
