M_Boats: Re: Cabin heaters

Cabin moisture: YES, any unvented heater will increase the humidity in your cabin, and it quickly goes to 100%, then condensation forms everywhere and it rains on you! Another source of water in your cabin: YOU when you breathe! To keep your cabin warm AND dry, use a vented heater. My first M15, then my Cape Cod Catboat, and soon my current M15 all had vented heaters, so the inside air was always not only warmer, but drier. John R. Butler theoldcat@cox.net
