    Recently we moved our boat to a rack and launch facility and it seems as if it's more humid in there than outside. I could be wrong but just in case it is I removed any of the linens on the boat that were cotton because that stuff holds moisture. I also opened up all of the cabinets and interior floor hatches as well.

    I keep the cabin door closed and the ventilation hatches on the deck closed as well. All have secondary canvas covers on them so they could be left slightly open if that helps.

    We bought this boat because it was one of the only ones that didn't have a musty boat smell and would like to keep it that way.

    I'm curious to find what works to control humidity in the cabin (without electricity) besides a giant bucket of damp rid.

    I'm in central Florida where it's always humid so all ideas are appreciated.

    Thanks in advance, Ken

    I'll add that the only standing water in the cabin is in the head. The bilge is dry.

    I kept our 260DA on the trailer year round. Damp rid was my go to and worked without fail. Add a fan to circulate and you will be amazed how much water you will pull out of the air and never a musty smell. No odors or mildew without the fan, but did remove more water with the fan.

    What did DampRid do to you?

    In all sincerity--without electricity, a product such as DampRid or a generic bulk counterpart is likely to be the easiest and most cost effective. If you can arrange vents, etc. to allow some sort of air flow, all the better.

    Wow didn't know they rack stored boats as big as a 390EC. Would like to see a picture of it being launched.

    We use Damp Rid and pull gallons of water out of the air every winter. We like the ones that hang in the closet. Usually will have one in each closet, forward and mid berths and sometimes the heads. No musty smell at all in the boat!

    I’ve found strategically placed Damp Rid’s to be the only effective option without electricity.
    Just make sure you check them every week or so.

    Thanks everyone. Damp Rid it is.

    Since the floor in the building is always wet it's like an environmental chamber so my plan is to close up the cabin and place two damp rid 4 lb buckets in there

    Maybe I'm being neurotic but better to plan ahead is my motto.

    Mold likes 3 things, the right temperatures, moisture, and food. We put the boat away empty and cleaned inside. We use the Damprid buckets and whenever we visit the boat for projects I run a box fan to move the air around and force it out of the dead spaces.

    I put them in each separate cabin space, and use the hanging ones in the closets. I also make sure to leave all closets, access hatches, cabinet drawers and doors open.
    I did take off all the towels and linens and brought them home to wash them, but then for the sake of storage I put them in vacuum bags, put those bags in a plastic trunk, taped the edges of the trunk to seal it, and put it back on the boat with a Damp Rid container on top of it.
    This is the first time in many years that I’m in a boatyard for the winter and not blocked up on my private property with the electric plugged in. I seriously miss not having the electric and am considering shrinkwrapping and staying in the water at my own dock next winter so I can have the electric.
    The boatyard operator where I’m blocked up is a great guy, and there is no problem plugging in every once in a while for a couple of days to top off the batteries, but staying plugged in all winter isn’t an option.
