If you have any type of vent on the boat then just glue a 12 volt computer van in it and hook it to the battery. A solar panel to keep the battery charged will produce more than enough power to also run the fan.
I've got two in the back of my boat in some clam shell vents on the back of the boat. I've unscrewed the deck plates in the anchor locker on the front so there's plenty of fresh air pulled into the boat and the computer fans pull it through and exhaust it out the back.
This has worked AWESOME. We used to have a mold problem but once I installed the fans to exhaust out the back it has made the most incredible difference AND it dry's my rope anchor rode and anything in the lazarette that accidently gets put up wet. Not sure if this will help you but it's a bunch cheaper than a solar vent and from what I've seen the fans last just as long. The best part is that the fans are only about 10 bucks or less each so when they wear out (and mine have been running for 3 years now) you can easily and cheaply replace them.

|sailingdog||The one you want, if you want the screw-in deckplate style is the N20504BRSC IIRC. They're more expensive than the other vents, due to the greater expense of having a metal deck plate, and metal screw in plate for the deckplate. Also, the body of the vent is bronze as opposed to plastic.|

The two I have aboard currently are older models that actually screw into a metal deckplate. In heavy weather, or if I anticipate going out in really bad conditions, I can unscrew the vent and plug the hole with a screw-in bronze deckplate. This is about as waterproof as you can get.
That said, I've yet to get water into the boat through them, and I've had waves wash over the cabintop. I am installing a less robust model for the anchor locker to help keep the anchor drier.
The new lower end models have a sliding sleeve that can close off the vent and prevent water intrusion in 99% of the cases... and seem to work quite well, but I've no personal experience with them other than seeing them on friends' boats.

Do you remove the vents and replace them with caps when you sail or do you just leave them in? Also, how watertight are they? Some vents that I looked at have a means of closing them off for bad weather and waves breaking over the vents.

I do not have the problem during the summer, just the winter when I am running the heating, and since I run the heating at the dock, the dehumidifier is not too bad of a solution right now.

Where does the rain go that gets down the mast. That seems to be the most likely way for moisture to get in a boat. Get rid of that water and you'll have a dry boat. Ditto for any deck leaks, which are a problem in themselves.
After ventilations, the smallest of heaters can keep humidity away. Do you have excess solar or wind power (a dump load) that you can put toward a small heater and a fan? (Or even better, a duhimidifier.)

|sailingdog||I'd have to ask, how much ventilation does your boat have? The biggest cause of condensation and mold/mildew is usually insufficient ventilation. Adding a few solar fans or dorades may greatly improve the situation without impacting the energy budget.|

I ended up using a small, energy efficient dehumidifier and a fan to keep the air circulating and had great results. I used the 3M mildew remover to get rid of the mildew, which worked surprisingly well, and in combination with the dehumidifier, found that my condensation problems ended. I think that with this winter in FL being colder than usual, the condensation lasted longer, resulting in the mildew. Usually, in FL, only my AC is in use and that dehumidifies the air as it cools it. Hopefully, my problem is solved and I will just use the dehumidifier in the winters.
