Excess humidity onboard can give your boat a musty, moldy smell. By installing the RiteAire dehumidifier, that problem can be solved. Designed for yachts ranging from 55 to 120 feet in length, the unit takes in the moist air, removes about 50 percent of the moisture, and then circulates the dry air throughout your cabin, saloon, or wherever you choose. The RiteAire dehumidifier can remove up to 70 pounds of water a day from the air, which is pumped overboard.
