My deck gets a little wet and has a semi self drain deck with two holes that drain to the splash well. My splash well is same level as main deck so When swells are up water will go into deck. I minimize that by plugging holes with scuppers and when deck gets a little wet i pull plugs while under way to drain (gets old). Thought of drilling holes into rear of deck and adding even deck drains but hard to reach area where hoses would be ideal. It can be done but I'd have to drill drain into transom below water line which I prefer not to do. So instead of hiring a shop to replace my entire deck what about adding a top piece of marine plywood over entire deck. Like other boats I have researched this will allow a 2" channel all the way around the deck so any water can drain at very least not pool around feet. It will also minimize a clear path from splash well to deck. My boat is 2001 Cape Craft and deck is not your new glass deck. There is fiberglass layer over marine plywood underneath but top layer is awlgrip. So would adding a top layer to raise deck a good idea or bad?
