Mrh, Sorry I don't know your name. I installed an 11" opening hatch w/screen in the foredeck and am very happy with it. I even sleep with my head forward right under the hatch. I considered putting one on front of the cabin, but the camber is extreme there and I was afraid that I might compromise the maststep which is on the roof of the cabin without using a compression post. I also considered opening ports on the forward sides of the cabin, but nixed it for the same reason. For me the bottom line is I need air flow through the cabin. I get claustrophobic in that small space and the lack of air just exaggerates it. Another enhancement is to leave the companionway hatch as far open as possible. This requires a screen and if it rains a bimini or boom tent helps keep the water out. A lot of cruisers carry umbrellas and I've seen Doug Kelch prop up his on a rainy night and leave his hatch wide open. Rick M15 #337 Bluebird
