I'm ordering some materials for a medium sized multihull build, but marine grade stuff is very hard to find here. I'm importing some rolls of fiberglass, and a pallet of p80 foam, however I estimate I'd still be short about 10 sqm. Not enough to foot the cost for an additional pallet of foam...

I’ve...
