Have built
the coachroof and the bottom half of the actual cockpit (see also
www.themultihull.net/ronh1.htm
&
www.themultihull.net/ronh2.htm).
Here is the coachroof mould, bottom with hardwood structure attached,
bottom with balsa core glued in, and the whole set up after gluing the
top on (It's buried under everything heavy we could find to fill with
water.)
