Re: Winter Moisture Control
I'm curious about winter moisture and resultant mildew that might accumulate in the bilges, if air circulation is further inhibited by a carpet. Moist air, cold hull = condensation. We have one we use in the summer and have to keep on top of it even then.
Nothing like a carpet on a boat in the morning, however. Even in warm water, the sole is usually cold in the morning. But, we have to keep it well vacuumed and, if not for the air conditioning and dehumidifier, I would think it would eventually begin to stink. It definitely absorbs moisture when we're way from the slip, which is one reason we run the AC about an hour or two every day, whether we really feel we need it or not. Keeps things dry.
When the outside air is 95% humidity ,changing one batch of wet air for another doesn't dry anything out. The bilge will be near 100% humidity, period, any time there is any water in it.. What causes condensation is a more than 2 degree difference in temperature between the air and a surface. Carpet reduces this difference by keeping the warm cabin air from contacting the hull plate, thus keep the air in the bilge cooler..
