Ok, I can do that. I leave a couple of ports cracked and there is a vent in the companion way hatch that I might be able to fit a muffin fan to. I like projects like that.

I don't want to pay for electricity at the yard where the Endeavour is when we aren't there .....
.... so made hatch covers for the three cabin hatches. The boat is in Florida and so far after about 6 years of doing this no mold in the boat with the ventilation they provide.
More on .....
...... how they were built here ......

For dealing with condensation in contact with fabric (under mattresses and cushions especially) consider Den-Dry. Similar to Hypervent, but a little stronger, and ships free from Amazon.

We hang up a couple of DampRid absorbers and keep a couple containers of Kanberra Gel (tea tree oil) below to help control mold and mildew. We are on Tampa Bay with a lot of humidity and these seem to help.
A big Maytag dehumidifier I got at a yard sale. Even in S Florida it will get it down to 40% in less than 24 hours after sailing. I tried it the first day using the built in condensation tank, and it filled the tank and shut itself off in less than an hour. So I bypassed the tank with a hose to the galley sink. It drips gallons of water via the hose into the sink after each sail.
Along the same lines...We were having problems with condensation under the V-Berth mattress during the colder months at the boat yard working on the boat. When we left we would stack the mattress sections up off the platform so no problem then or during the warmer months.
We decided to order perforated tiles and give that a try and that seems to of taken care of the problem.
It was pretty easy to cutout openings for access to the compartments under the V-Berth with the tiles. A little more info here .....

One of the things I did to create ventilation was to install a "bathroom" fan (2 photos below).... I installed a Vetus mushroom vent (so that I could close it completely), covered it on the outside with a screened cowl vent to prevent rain and spray from entering.... then I built a small fan box to cover it on the inside of the boat..... a 4" push-pull (reversible) moves a lot of air in a hurry... sometimes you want to vent out, and at other times its nice to have some cool air forced into the boat.
when the fan is not on, but the breeze is blowing, it acts like a dorade vent.
I’ve had generally good results with desiccants year round. I have both DampRid buckets and the renewable H2Out canisters distributed throughout the cabin and lockers.
In the summer when I’m on the boat, with no ac and no dehumidifier, the cabin tends to be wide open and very well ventilated with the companionway, two hatches and nine operable portlites. When away and the boat is closed up tight (There is still some air circulation through vents and hatch boat gaps.) the desiccant is very effective. I do always drain and dry the bilge and leave locker doors open when I close up the boat. Last year, I started leaving a small fan running when the boat is closed up. It may or may not have increased the moisture collected by the desiccant, but the cabin just seemed to smell fresher when I returned.
The only time I see any noticeable condensation in the summer is if the boat is wide open on an unusually hot humid day early in the season when the lake water is still cold. Then I’ll sometimes get some condensation in bilge and locker areas below the waterline. The upside is that the cabin feels a bit cooler then.
During winter storage, the desiccant does nothing in the cold dry winter months, but is very effective in the spring/fall temperature/humidity swings. After the shrink wrap goes on in the fall, I open the portlite in the head for some added air circulation. Also, everything is pulled out of lockers, lockers are left open and cushions stored on end for air circulation.

I have no problem with condensation anytime in the year here in the Pacific NW. When on the boat, I run the heat as needed which even in summer is a couple of hours first thing in the morning. That always keeps the cabin dry. When not on the boat, I run the heater for 12-hours after leaving the dock and then close it up. I do not have any leaks and have a day/night solar vent.
