i had mentioned last summer when i started the demo how the sides of the hull had a layer of spray foam on them covered on the inside with glass, initially i suspected it was structural.
fast forward to yesterday, i had to cut some away where the transom was tabbed to the sides of the hull.
foam is about 3/4" thick and is covered on the inside with light (maybe 3/4oz CSM) and not lots of resin.
the piece i cut from the port side was wet about half way up, i also saw some water along the bottom edge.
on the starboard side its mostly separated from the hull as well.
so is it structural ?
a guy i work with worked at the glastron/larson plant in little falls for quite some time, he said it was for sound deadening (but what does he know ?, he's not an engineer)
personally i cant see it being structural based on the fact that al light layer of CSM with a sparse amount of resin on it has relitivly no strength.
but the real answer comes from the 1991 Glastron brochure
"Even special noise suppressant foams are injected into the engine compartment and side walls to enhance on-board ambience."
i will leave the dry parts up front, but i have no concerns about the taking out the wet parts.
though this was also in said brochure "Some of the little things Glastron does are never seen but mean a big difference in value and performance. Like encap-sulating the fir stringers with fiberglass for added durability and strength"
epic fail on that one, oh well on we go.
