Looks like your gonna be fishing on the boat. Made some nice additions already. Nice cooler, should work well for now, LOL, the boat catch's fish, you might need a longer one for the fall and spring season.
You did a pro job on the vinyl, cutting it to the edge of the drain channel, and glued it down. I once used a product years ago called nautilux, installed the same way, but found after a few seasons in the elements that the edges began to curl, or lift slightly. I used a clear marine grade caulk at the edge to prevent it from going any farther and it worked well in sealing out any water from wicking under the vinyl. Just a in case is all.
Ummm bet it don't take long to get to 50.

Easier to do when your sitting.
You put in alot of work into the boat, looks like it was worth every minute, and thanks for sharing.
