Please keep on topic.

The MiniCups were intended to be small cheap sailboats anybody could
build. However, they were too heavy due to the use of 1/4" (I used
3/16) ply and were not intended to be glassed so they did not last
long. I want a modern version using modern methods yielding a
considerably lighter boat that lasts longer. I also made major
improvements on the sail and spars so that problem is solved.
So, stitch and glue maybe with epoxy saturation of the wood and
covered with 4 oz glass? I am worried this might result in a heavier
boat because the weight of the fillets relative to the boat size may
be too much.
Is it worth trying to incorporate more high tech stuff like Corecell
or similar foam building materials?


Why bother when you can buy yourself a brand-new sound little sailboat
with a proven track record and suppliers of off-the-shelf parts?

You seem to enjoy "stuff" that is in a constant state of disrepair.
I don't.

Spoofer alert! Only a fool wouldn't know that some people actually enjoy
and take pride in building and maintaining things.
