Picked marine plywood over cheap OSB for my cabin floor rebuild - saved my butt last week
Had to make a call between 1/2 inch marine ply at $65 a sheet or OSB at $22. Went with the plywood. Three days later a copper supply line burst under the sink while I was at work. Came back to six hours of standing water in the bilge. The OSB would've turned to mush by then. Marine ply just swelled a bit at the edges and dried out fine after I hit it with a fan for two days. Now I'm wondering if anyone else spent the extra cash on something and had it pay off quick like this.

Wait isn't marine plywood actually just exterior grade plywood with a different glue? I thought the main difference was no voids in the core layers. Your bilge situation still ended up way better than OSB though so that $65 a sheet seems like a steal now.

Swear I've learned more about plywood glue than I ever wanted to just from my own mistakes. Guess that makes me a professional at picking the wrong material now, so that's something at least.
