I put a low-profile, PVC vent in the forepeak of my 15, immediately forward of the cabin house. Went with the red-painted inside surface. Looks cool. Anytime the boat's moving, there's air moving through the cabin, airing it out at the very least. It can be removed and replaced with a deck cap, to keep the wharf rats out when left in a slip. I'd like to just screen it and let air circulate all the time, but right now I have rotted cushion covers from water leaks around through-top wiring (masthead light) -- albeit after 24 years -- so I use the cap. Still, I think that had the cabin ventilation been better, I might not be gouging out gelcoat blisters this month, instead of sailing. For reference, it's on p. 545 of the 2008 West Marine catalog. Because it's flexible, you're not going to tear sails or toenails on it. Of course, it's not a powered vent, so if there's no air moving outside the boat, there's none on the move inside, so no score. The fact remains, though, the 15's forepeak is a solar still if the sun's out, the air smelling of fiberglass and bilge compost. Something to keep in mind if you're sailing with kids who want to hang out down below. ************** Gas prices getting you down? Search AOL Autos for fuel-efficient used cars.
