See pic Green = tube , Black carbon, Red holey plastic

Wasn't much holding them in. Whats your intentions with the yacht? eg coastal or offshore What were the original floors made from ? hard to tell scale but looked about 40mm thick

Our 3 go to's are okoume, yellow cedar, and iroko. When you say structural floors can you give and example, not a place for ply in my mind.
