Rick: I found with my M15 that when I cut out one of the two shallow cockpit lockers to open it to the bottom of the hull, I got quite a lot of ventilation when it and the main hatch were both partially open. I had earlier installed a Beckson Vent-o-mate in the foredeck, which gives some ventilation, but the cockpit locker gives more. --Gary Hyde Pullman, WA gmhyde1@mac.com M17 #637 'Hydeaway 2' M15 #235 'Vanilla' "...There's nothing quite like messing about in boats..."

I'm planning to install a 12"x12" (9"x9" cutout) hatch in the forward deck right in front of the cabin. My intent is to increase ventilation through the cabin. I have considered a Nicro type vent, but prefer a passive, no noise option. I don't think a cowl or dorade box will work well because the deck is very small. I also considered cutting a port or two into the cabin sides, but nixed that being worried I'd weaken the roof/mast step.
So it seems a low profile hatch is the best solution. My question is, "Which way should I orient it?". My first thought is to have the lid open towards the mast. This way, at anchor, the lid would direct a breeze down the hatch. However, I've seen some hatches mounted the other way like on an M17. What's the advantage of this orientation?
Thanks,
