Plan and Progress
Instead of tearing everything out of the inside, I decided to do the repairs in sections, beginning aft and working my way forward, dividing the work up into thirds, as per the 4' width of the plywood used in the original sole. I feared that if I removed all the structure at once, it might be difficult to maintain hull shape. Of course this approach means that the keel and side beams will not be solid pieces, but will be sections joined with butt blocks.
After removing the hull "top," I tore out the old transom, flotation foam (more like non-floating crusty sponge at this age), aft flotation compartment forms and sole. Also, I removed the floatation foam "blocks" glued in beneath the sole which had actually served to trap moisture against the wood, contributing to the rot problem.
Another structural modification I am making is "sinking" the center floor section down to the base of the side beams to create a channel for moving for and aft, and making the aft side bench seats I plan to install more comfortable.
Either all of my structural "guesses" will make her a more useful boat when she is done, or will lead her to fold up like an accordian the first time we hit a wake! I can't wait to see which it is!
Here is a photo of my progress up to early July, 2008:
