I visited
one plant in Bristol, RI that was in a building about 80'x180'. They had a
layup area and a 20'x60' post cure oven down one wall, component fabrication
down the other. The 30' wide line down the middle had three 30 something
sport boats and a 46' cruiser in the works with plenty of room around them
to work.

That sounds like somewhere on Broad Common Rd. I'd put my money on Barrettt
Holby's shop ;-)
If not, then Barry Carroll, but IIRC they were a bit bigger.
