The hull and deck joint extrusion was called H-metal. Caulking was placed in the crux of the H, it was slipped over the hull edge and pop rivets were used in holes drilled through the extrusion but not all the way through the inside cosmetic piece. The deck was then installed the same way. The rivet heads were casually caulked to prevent leaks prior to installing the rub rail into the extrusion ears. As I recall, the ends of the extrusion were not sealed. Any water in there should find its way out without additional permanent drainage holes depending on the slope of the extrusion.
This is one of those building techniques where I prefer to keep my opinion to myself if you get my drift. Dang, I installed a lot of these.
Drawing attached, you'll probably have to rotate it after opening.
