Aft deck waterproofing/drainage
Posted: Thu Jul 20, 2017 11:54 pm
Hey everyone!
Been watching the forums here for a while and finally decided to post. I've decided to replace the aft deck on my 1973 F32 during the upcoming winter. It currently has the (what I imagine to be) original nonskid deck covered by a layer of 1/2" plastic sheeting of some sort installed by a previous owner, which is very slippery. I also don't care for the layout, which has two wide sheets on either side of a narrow center sheet, which means the lazarette hatch spans three pieces of material.
I plan on pulling out all the old decking, replacing any rotted support framing underneath, and laying down new glassed and non-skidded plywood. As part of this process, I'm installing new hatches and storage, and fixing the drainage on the deck.
Currently, water drains from the deck between the deck plates, and between the deck and gunwales, which are not caulked. It's then pumped over by the bilge pump. Not a great system. I would like to install deck drains and scuppers. Figuring out how to seal the deck is pretty easy. I'm having a hard time figuring out how to make a good transition from deck to gunwale. I don't want to just dump a bunch of caulk in there. I swear I've seen some type of plastic (maybe pvc?) molding which is 90 degrees, and for which there are corners or other joints. I could use that under the joint between the two with some caulk. But I can't seem to find anything like that online.
Does anyone have any ideas where to find this stuff, or other ideas for what I could do?
