Humidity

[SurlySailor]

So we are out cruising in the Northeast US right now and one of the things we are trying to control on board is humidity we are finding that everything is getting very wet at night when the fog rolls in. We are pretty constrained on power and anchoring out, are there any solutions that we don’t know about to dealing with everything being constantly wet at night.

Unless you get a genset and AC, you learn to live with it, unfortunately.
Tarps/awnings/biminis will help with ‘falling damps’, but you are ventilating humid air, no real way around it without shutting everything up and cooking to death.

Ventilation is the only help and it’s not much of one.

I’m cruising Maine right now and haven’t seen the sun for days. A wet most rolls in all night long. Cabin humidity between 90-100% all the time.

Just keep the air moving in the boat. Fresh air in. And pray it changes to more summer like weather soon.

A dehumidifier is the other option but you’ll need to run a generator.

If you are closed up in your boat due to cold, foggy, nights (hard to imagine in July, but...) a long term solution will be a diesel fired heater of some sort. Heating the interior with something that uses interior air and ideally exhausts to the outside will reduce humidity in the boat. (Propane heaters, and even running a stove ,does little since the products of combustion, which contain the moisture, remains inside the boat).

However, if it is not cold enough for a heater, then plenty of air flow may help the problem.
