My 8 yr old homebuilt MiniCup sailboats may have reached their
end of
life. The plans emphasize that they are intended to last only maybe
3-4 years so mine have done well. Both have been repaired at least
once to get rid of rot but the rain and humidity here in N. Fl makes
it a losing battle. #1 has been sitting upside down for a year
waiting for me to re-do her topsides and #2 has been sitting out
where
I always bail her out. Last night I looked inside #2 and found her
insides filled with water so I pumped out the compartments. Still
she
seems very heavy and I think the 3/16 ply is saturated. I did epoxy
and glass her on the outside and part of the interior but the ply
ion
the inside is like a sponge. Am not sure what to do with her.
Back to #1 whose bottom is still good along with much of her
structure. I am considering using corecell foam to replace the
decking and saturating the remaining wood with epoxy.
I'd like to totally re-design the MiniCups to use modern
materials so
they are not disposable boats but I do not want to use ply for
such a
small boat because it is then too heavy.
Can anybody suggest any guides on using corecell as the forms for
glassed over structural parts and then using sheet corecell glassed
for the hull? How do you glass both sides of something that is so
enclosed like the interior of a small boat?

Waaaaayyy too time and $$$ intensive. Just make them out of good !088
Ocoume and don't skin the outsides with glass. If you paint them
every
few years, you could get 20 out of them. I have a hull I built of
1088
almost 12 years ago that is still sitting unprotected in the yard, it
has not started to delaminate or rot yet...



And when he's not using it as an outhouse, it is used as a trash
container.

P.S. You still living across from the cemetery?

How's that boat of yours, Bertie?

Couple of thoughts. The okume suggestion is good if you want to
build a new one, very strong, light weight, and rot resistant. More
radical is to use one of the old boats as a male mold for a new hi
tech composite hull. If you cover the old hull with plastic sheeting
and mold release you should be able to pop the new hull off when
you're finished with the glass and foam work, even if you have to use
a few staples to hold things in place while you're working. Ideally
you'd like to use pre-preg glass or some sort of ultra slow cure epoxy
so that you could vacuum bag the whole thing. It will end up slightly
bigger than the original but that shouldn't be a problem unless you
are doing one design class racing.

My lobsta' boat is just fine if you want to talk boats, spoofer! Just
last weekend, I had a fabulous party aboard with lots of Washington
insiders. Catered by a fantastic restaurant I used to visit in San
Francisco. Had the chef flown in by private jet.
