Default Controlling cabin humidity

With my boat on a trailer I don’t have the option to run the ac to control humidity/mold. What’s the best way to control humidity? Previous owner had a dehumidifier running that drained into the galley sink. Are there better/more effective options?

There's a product called damprid that you can try. The type you hang in random areas. It absorbs moisture into the bags.

The dehumidifier draining into the sink is going to be probably your most effective option. It's shocking how much water they can pull out of the air.

Cabin door open to promote airflow with a dehumidifier and a small fan for air circulation?

what size boat we talking about?

On all my parker pilothouses, I would lock all the windows, doors and put a hanging "damp rid" lemon fresh scent in the cabin. It worked PERFECTLY with NO mildew/ mold/ growth: Smelled lemon fresh until the day I sold them all. I have a new pilot house on order ( picking up this week): She'll also get lemon fresh Damp rid bags hung: I replace every 30 days.

Get a dehumidifer and connect to 110V, run a drain hose to sink or outside of cabin. Not sure if damp rid would work in a larger cabin like the GW 330.

I've been using Damp Rid in my cabin for years.

cabin door open with a dehumidifier is just going to make the dehumidifier work overtime. i would shut the door and let the dehumidifier do its job.

if not dehumidifier then door open and fan to circulate!

I live in the Humid capital , south Florida on the Gulf . Of the different things tried , the $30 amazon dehumidifiers have worked the best . Set up to drain into sink . No maintenance and pull about a cup of water out every day .

+1. When I was blowboating we'd do this after a regatta and all the sails were dry as a bone in a day or so.

Damprid works in a pinch but not as well as a dehumidifier.

Did you leave the cabin closed up?

If you open the cabin door and run the dehumidifier all you're doing is attempting to dehumidify the atmosphere. Same concept as leaving your front door open to air condition the neighborhood.

Close the door and run the dehumidifier, the inside will be dehumidified.

Dehumidifier into the sink and a fan to move the air around.

Electric dehumidifier if you have access to power, pellet type dehidification pellets if not. Damprid works well, but is simply Calcium Chloride...same thing as driveway ice melt. You can make a big damp rid device by stacking a 3 gallon bucket in a 5 gallon bucket, and perforating the bottom of the 3 gallon bucket. Fill the 3 gallon bucket about 1/2 way with ice melt pellets and you can suck the moisture out of a fairly large area. I would leave the cabin closed up to the extent possible.
