Solar Vent that threads into Dorade?
Does anyone know if they make a solar fan that will thread into a dorade box? I typically have the threaded caps installed on my dorades but think it would be really neat if i installed a solar vent to keep the boat fresh while I was away. I think it would be better than just the cowls.

Don’t think they would do much good. The air would just go out (or in) the water exits.

Re: Solar Vent that threads into Dorade?
I didn't think of that. Maybe could block them off with something since it would only be used while away, then unscrewed and put away.

Re: Solar Vent that threads into Dorade?
I've got a solar vent installed in the deck above the toilet/shower hoping it will reduce the humidity.
Boat Exhaust Fan Caravan Solar Air Vent Deck Ventilator W/ Battery Switch Combo
https://www.ebay.com/itm/Caravan-Boa...-/132652249792
The inlet is a little bit bigger than the diameter of a normal dorade "funnel" ventilator.
I worried that water would come into the boat if the deck was awash so I fitted a screw-on inspection type cap on the inside of the deck over the vent inlet. I realize I will have to fit a f/g cover over the solar panel to stop the fan working when not required.
Incidentally I made up some f/g hatch covers to protect the acrylic hatches from u/v damage, give privacy and to stop the yacht heating up like a hothouse in the tropics.
I considered canvas covers but when I looked at the cost and the life expectancy (guaranteed for one year) I thought f/g was a better option. (I have ss latches in the mail so that I can secure them in a gale)

Re: Solar Vent that threads into Dorade?
I have a solar fan that screws into the dorade box threads on my Passport. It works great despite any air flow through the drain holes. I’ve been looking for a source to buy several more, and I haven’t been successful.

Could you post a phot of this fan, maybe as a group we can search it out if we see one.

Re: Solar Vent that threads into Dorade?
I've two Nicro solar-powered ventilation fans, made by Marinco.
http://www.marinco.com/en/products/v...olar/day-night
At dock, I often place one, in withdraw air mode, over my spurling pipe to move air in the anchor locker/sail bin.
In other situations, I unscrew two cowls from the dorades, one to port and one to starbd, and screw in one fan in push mode and the other in extract mode.
I don't consider the water drains of the dorade boxes a signficant matter. If it were, the cowl vents wouldn't work either :-)

Re: Solar Vent that threads into Dorade?
Maybe if you fit one of these under your dorade ventilator inlet it would be the way to go?

I too have these, three actually and when they work they work well, but my experience has been that longevity is not their long suit and at A$300.00 each I will be looking for an alternative next time one fails.

In your experience, Rob, what fails?
I've replaced the batteries (NiMH batteries, which I buy from Jaycar) a time or three over the past dozen or more years, but the rest is still working.

I’ll be happy to post a photo but it’ll be a couple weeks until I’m at the boat again. Regarding longevity, mine has finally failed (plastic battery housing brittle and broke) and it’s at least 10 years old, possibly much more.

Yes. Definitely post some pictures so we can try to figure it out!

So you're saying that the threaded portion of the bottom of your fan threads right in to where your cowl would normally go? If that's the case, I'll call them tomorrow and buy two. Leaving the boat to turn into a hot wet oven for a week at at a time is good for nothing, and I would feel a lot safer running a couple of these instead of the A/C while away. Thanks!
