ok
I have a bridedeck port light and I use it a lot , its open most of the time, rain doesnt really comes in the boat through it, so it stays open ..

I have a nicro 24 hour vent in the restroom. AND a 24 hour solar vent on the front inspection hole. The later I put there because my holding tank was real smelly and since I put that vent there the inside of the boat is fresh ( The stink was real bad, I am planning to redo all the lines over the winter )

Boat is super dry and fresh after I invested in the 24 hour solar vents ( 3 inch dia ) Only thing one need to do once in a while is to clean the little fan, otherwise they get real loud and drive me nuts when I want to sleep in the boat

p.s. I guess one could put some stainless louvers in the door as well... but I havent seen the need for them
