Dehumidifying the cabin while underway

In a seperate thread I asked and received good advice about insulating the boat since, especially in colder weather, we do get a lot of condensation. A related question here is how to best dehumidify the boat. Mind you, I do not mean plugging in a dehumidifier at the dock, but what, if anything, seems to work when underway or at anchor and things get cold and wet. We have used some of those moisture absorbing "buckets", which work on a small scale but they do add up $-wise and probably cannot handle a larger volume of air on a sustained basis. Keeping ventilation going is certainly part of the answer and I wonder if installing a dorade or two, or a solar-powered vent or something of that sort might be part of the solution.

Over to you guys out there!

Ventilation if it's warm enough.

Minimizing humidity from cooking, showers and heaters.

Also these can operate on 12V (they use a 110Vac to 12Vdc converter).

They draw about as much as running lights and can remove 4-30 oz/day, depending on the temperature. About 20x faster than a CaCl2 bucket.

If a dirty bottom slows you down what do you think it does to your boat

Re: Dehumidifying the cabin while underway

as seas do not generally tend to break over my bows, i keep overhead hatches open, and ports closed.
i have yet to know of any extra humidity in cabin on any boat i have sailed while underway.

Re: Dehumidifying the cabin while underway

If you can keep air circulating, you can usually keep things reasonably under control. Solar powered hatch fans are popular.

Re: Dehumidifying the cabin while underway

when you are sailing, air is circulating. easy peasy. UNLESS you sail with a closed up boat, which is very stifling.

Re: Dehumidifying the cabin while underway

I think some may all be missing the fact that Flandria sails where the water temperature is 50F. Different problems. The hull will tend to sweat on the inside and fresh humid air can actually make this worse.

Tropical solutions are different.

Re: Dehumidifying the cabin while underway

cali waters are 50s, also-was not a problem while underway to keep boat aired out and dry and comfy.

i have sailed a lot more water than merely tropical. hell i even grew up in snow and ice--lol we learned to sail in hudson river,and thanksgiving was our best sailing time,as we had all family in place and time to sail in an antique historic wood boat.....
