Non-wood questions are welcome.

You need some kind of overlap. This can either be molded into the deck and hull or tape layed across the seam. Molding in a joint which overlaps is difficult. The tolerances required for a tight/strong joint are difficult to acheive. Resin shrinks slightly after curing and the resulting change in size needs to be accounted for when making the plug to make the molds to make the boat. If you can do it, a molded-in overlap will probably be the strongest system.

The primary advantage taping the joint is the tolerances do not need to be as tight. The tape will conform to irregularities.
