I can get to my aft nuts and bolts from inside the vee birth. The forward ones I have access to also from inside the vee birth but way further up inside; like up past the little wall at the forward most point inside. They are next to the anchor locker, I can kinda get in there maybe if I squish in as far as I can but it looks incredibly difficult; esp because I get claustrophobic...so I'm not sure about how to get those either. Maybe with an extension and tranquilizers lol; it looks challenging for sure. I wonder if that little wall is removable, then it might not be difficult at all but I have no idea about that either. It doesn't seem structural - that little wall I mean so maybe it can come out? I wish I would have seen this earlier I could have taken pictures of those bolts, but I just left my boat. I'm also worried about the extensiveness of the rot in there. What year is your 28? I would have thought that area would be the same as mine...?
