Dave must be very skinny to be able to get under there
I've been under that area as well and to be able to do the work he accomplished is no small feat.
I've been trading e mails with both Dave and Conner about this. Sorry I have not got back to you guys sooner on this issue. I wanted to inspect both my boats before I made any comments on the subject.
The 25 that I just re did does not have any evidence of delamination on both the starboard and port stringers. The other 25 seafari that has been sitting is difficult to inspect the starboard stringer but I did not see evidence of delamination on the port side.
I can see from Daves pictures and from looking at both my boats, there seems to be some inconstancy in the way that these stringers were glassed to the hull. On the 25 that I just re did The woven roving that glasses the stringer to the hull extends about 10 inches down from the inboard side of the stringer onto the hull. On the outboard side of the stringer it extends another 8-10 inches and stops partly going up the side of the hull. On the 25 seafari that is sitting it is glassed the same on the inboard side however on the outboard side the glass extends significantly more up the side of the hull. On both boats the woven roving goes up the side of the stringer on both sides and over the top to overlap each other. In Daves pictures it looks like the glass only goes up half way on the side of the stringer.Both my boats were built in 1973. Here are a few pictures.

Another potential problem in any of these old boats is the forward bulkhead under the V-berth. In most of these older seacrafts they consist of 3/4 inch plywood tabbed to the hull. There is a drain hole in the bottom most part of the V and water can get to the exposed bare wood. Once this bulkhead begins to rot out it creates instability and can lead to flex. Below is Daves diagram were I've added an arrow pointing to the bulkhead.
happy seacrafting to all
