You can return to your boat after the winter or after a vacation abroad to find mould or mildew but not with a DryBoat stainless steel dehumidifier from Ecor Pro.
There are several considerations when shopping for a dehumidifier for your boat. Most “home” dehumidifiers drain into a “bucket” which is a problem if you're gone for six months as no one is available to drain the bucket daily. Most home units will have a permanent drainage facility but if this blocks with dust or mould or even kinks, the water can back up into the unit and into the cabin causing a flood.
Another issue is how to fix the home dehumidifier in place? Usually its drained on the galley kitchen drainage & into the galley sink or into the bilge. However, if the bilge pump failed there might be a problem. Often the dehumidifier is literally tied in place with straps & tape through the handle but its all not ideal.
The best solution is the Ecor Pro solution. A dehumidifier that can link to your heating system ducting to keep your whole boat dry. No liquid water is produced just moisture vented away to the deck area or through the air intake vent to the engine room. Even simpler is building it into the cabin having the unit secured with the convenient feet. About the size of a childs shoe box but more powerfule than a typical 16-25 litre cmpressor dehumidifier.
