John,
Tinker away. It sounds like you have the perfect boat for this type of
work. Five years is a long time. Personally I would rather be out sailing.
Speaking of sailing, it looks like the deep freeze we have been in will finally
disappear by tomorrow and I will have to go sailing.

Rummy,
I still have to re finish my boat above the rub rail when I do so I might
sand with 60 grit and bond a couple of sheets of new glass over the deck
and
cabin and shoot new gel coat over that. Properly done that's the equivalent
of 1/2" of plywood reinforcement. I also found a company that sells the
molds for re doing the original checking on the non skid areas. The hull
deck joint is also on the to do list. The interior redesign has fixed the
port side deformation by the addition of the port side bulkhead. I had no
problems with the compression arch taking the loads applied and while I
lack
your experience in pushing the outer edges of rhodes performance, Kinzua
currently pushes it plenty hard for me. I will admit to liking the thought
of having both the oldest and the fastest rhodes on the water and I have
always liked to tinker with things. I probably have 5 or so yrs of putzing
to do before I'll be satisfied with this project.
