hub of boatbuilding in Canada and have seen many boats new and old repaired

Hey, I've seen many boats built with polyester that had the
tabbing pull free from plywood bulkheads. You can use
polyester if you like, but given the amount of epoxy you're
talking about for a 20' deck repair, the cost difference is
trivial. And I think 2 x 12 oz biaxial would be ample
for an inside skin, given typical spans you'd find on this
size of boat and a core thickness of = 1/2".
