These are against our club bylaws. Insurance frowns on them too. Not sure if they would deny a claim if it burned down your boat.The best dehumidifier that I have found is a small electric heater. In my case it is cold and damp in the winter so mildew will grow inside the boat. A small heater clears it right up. Just needs to be a couple of degrees warmer. I tried the chemical dehumidifier and the electric one with no noticeable improvements.
+1 on Eva dry or similar dehumidifier from one of the big box stores. I’ve been running one for the past few years and discharge into sink. Set it at % desired andlet it run. Keeps boat dryI went with an Eva-Dry like the one in this article. I punched a hole in the reservoir and drain it into the sink in the head.

Then moisture is still getting into the boat.I've tried the Eva Dehumidifier with no noticeable improvement. Modern electric heaters are pretty safe. They have automatic switches such that if they are knocked over they turn off. West Marine sells one specifically for this purpose.
Or I could just use a heater.Then moisture is still getting into the boat.
- Reduce or eliminate leaks.
- Seal all ventilators. This is often overlooked. You don't ventilate and dehumidify. it is one or the other.
Looks like the one these kids use in their Catalina 30 in Vancouver.Has anyone had luck with models similar to this?
Nice, thanks for the link! If I go that route I'll report back.Looks like the one these kids use in their Catalina 30 in Vancouver.

You really don't want a dehumidifier draining into the bilge. It's just another source of moisture. You need to get the bilge dry and have the dehumidifier drain overboard directly.
