Hi there everyone, first poster here.
Recently bought my first barge (a Sheffield Keel 61 footer called Sobriety), and getting her ready to become a liveaboard. Her interior deck is in some places completely rotted away, and appears to have been made from some sort of inferior grade chipboard, topped with oak floorboards. Our plan is to gut the entire interior and rebuild from the deck up, but I'm wondering what is best to replace the interior floor with so that we don't end up having to face the same problem down the line. I'm pretty sure all the moisture has just come from her being sat empty for a few years, her bilges are fairly dry.
My original thought was marine ply backed with some kind of sealant layer (obviously still leaving room for bilge hatches) Am I on the right track with this?
