Another hurricane hinge problem

Okay team, this photo is pretty obvious about what is wrong, but basically I wasn't able to let the hinge run beyond the edge of the galley, leaving a big gap for water. I also had to put a spacer in to help the gap. I've still got a while before I'm done with the rest of the teardrop, but I'd like to find the best way to seal the ends here
I would really like to avoid running a big ugly piece of rubber or plastic the whole way across the seam, but I've seen it done that way. I'm also told there is a way to cap the end, but not sure how to do that while still allowing it to pivot. I'd like to be as descrete as possible, while still being practical. Could I do the pond liner thing just on the 1 inch at the ends?
