My daughter and I built a Ganymede with bulkheads but no hatches. I made the bulkheads from 3mm Sapele with deck plates in each for access and to air out the ends off season. I then installed the bulkheads with marine silicone caulk instead of epoxy fillets, so they can be more easily removed for hull repairs if needed.
