[MHml] Mast WAS Daggerboard construction

[multihulls at steamradio.com]

As a new reader I wanted to comment on past discussions of daggerboard cores 
in france. They get away with light foam core because the core only supports 
one of two types of  intenal  structures.
1. Imagine the shaped foam blank is cut into strips about the thickness of 
the board and each is wrapped with double bia material and then glued back 
together, and then the section is over wrapped with the predominatly ud layup.
2. Each half board is laidup and an offset set of stringers are laminated 
over a light core. when the two halves are bonded togerther the stringers 
nest together perfectly.
