So to back up to the hypervent conversation...Those who use it, do you leave it year round or remove in spring/summer?
Year round. I just take it out to spray with cleaner and pressure wash.
1.It fits just fine there, can't see less ventilation being better than more.
2. It gets cut individually and I don't want to play tetris in my boat anymore than I have to.
3. removed, it's just gonna take up more space somewhere else, or get lost. Also the edges are sharp, and I've caught myself on them a few times when laying it all out.
Also, not sure if it's coincidence, but I had a bunch left over, I put it cloth side up in my lazarette. My lazarette and cockpit lockers all leak right now, the only one where things aren't moldy/smelly is the one where they are all sitting on the hypervent. So save all the offcuts, they can be handy!
BTW I removed my foam tiles on the floor while I was pressure-washing the V-berth for paint. Left them off at night, and forgot, my legs were freezing when I was sitting reading, and humidity in the boat was worse than usual.
Put them back into place, and things were much improved :-).
