Forward Hatch in an M15
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, Rick Langer M15 #337 Bluebird

Rick, IIRC, Jerry was concerned about a bow-opening hatch coming open when trailering, with resulting damage. Hence the opening to the rear. Additional ventilation would be good and in the past I have thought about adding something. My vision was one or two round, opening ports on the sloping forward portion of the dog house. That would provide visibility to weather when anchored as well as fresh air. And keep the tiny foredeck unobstructed. That said, I have ridden out several storms in the closed cabin and not felt smothered. The cabin is so small that it doesn't need much ventilation. Now that I have a quiet nylon tarp/boom tent, I can remove at least one hatch board even in a hard rain. Since the tent also keeps dew off the cockpit and gear overnighting there, I put it up nearly every night.

Rick, Your point for why a rear-hinging hatch might be desirable is totally valid - the breeze does come in nicely, especially with a windscoop. Also, you can more easily pop your head out to look around (forward). In addition, it's easier to stuff sails down below, if you should ever want/need to. One point in favor of a front-hinging hatch might be that you can leave it open longer when underway, without being as likely to get spray in the v-berth. And, as was mentioned, it's less likely to cause trouble when trailering, although conscientiously locking it down would work too. I wonder how the breeze factor compares if you're using a windscoop, when it's hinged at the front? FWIW, --- Rachel
I would prefer a rear hinged hatch as I feel it would catch more breeze while at anchor, don't think it makes much difference if tied to the shore or at a dock, however the front hinged hatch does give one a better view of the stars while laying down.

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..."
