fiberglass is an OK material for boats. after owning a few that had a
balsa core, I'd never do that again. with age and previous owners, you
can end up with balsa/sponge core---suitable for a land fill.

I hear you. This means I need to avoid those "fiberglass" boats that
have too little fiberglass. Now, I just need to be able to tell which
one is "true" fiberglass boat and which one is not.

I wrote to "This Old Boat" magazine to see if they ever did a story or
put together a list of solid fiberglass boats. the answer was, "no".
good research project.

I guess they didn't want to hurt their revenue from advertising.

talked to a fellow who had just put a new
transducer in a Fischer motorsailer, he said he was amazed to drill away
and find the hull to be an inch and a half thick, solid glass. yeah!

Seem like the Fisher Motorsailer is a sailing boat from 1970's. I guess
they still didn't figure out how to cut corner back then.

Nice to talk with you and have a great weekend.
