[quote=dmgbear55]If there is a bulkhead at the rear beam, then the very best solution is to add the inspection hatch in front of it. This hatch also lets you inspect the front side of that bulkhead for cracks and probably just as important more of the inside of your skeg allowing you to beef up and repair from the inside of the hull. Getting access to the rear part of the tramp rail rivets then is just bonus. Far and away the best way to reinforce the rivets from pulling out is with the washers. I added hatches in front of my main beam so that I could inspect that bulkhead as well as see the area forward of the beam. It was a pretty simple job to do.
Or just consider drilling some of those holes out to the larger diameter 1/4" and see if that improves the holding. I think the only challenge to the larger rivets is pulling them with a standard tool.[/quote]
