I've replaced the decks and stringers of two boats using 3/4 MGP, so I'm really interested to see how well this product works. If it can structurally hold up as camper trailer decking without any more flex/sag than the MGP, then I don't see any reason why it wouldn't hold up as boat decking too. MGP is good and lasts a long time even in marine applications, but it sure would be nice to someday build a boat deck that I know will last indefinitely.
