EXPERT TIPS FROM A SURVEYOR
Most GRP yachts follow the same basic design principle. The rudder blade is produced using a pair of female moulds that are laminated and forced together with wet chopped strand mat around a stainless steel stock with some stainless steel tangs welded onto them.
Others use the same principle but with an aluminium stock rather than stainless, and then there’s the odd exception that uses a marine plywood blade, often sheathed and with a stainless steel stock.
