looking for information on hulls
Okay folks, here's a tough question. In the early days of fiberglass hulls were thick and solid. Then they adapted to cores which reduced weight and cost and still made a good product. Is there any source of information that would list the makers of sailboats in the early years of fiberlass hulls and what years they moved to the cored hulls. I'm thinking the move started about 1970 but I'm sure it will be different for different companies.
Can you shead any light on this for me?
