Solar/Air Vent Effectiveness

How effective are solar/air vents at circulating air and preventing mildew/moisture in the cabin?

I'm considering installing one on my deck hatch. Given that my budget is limited, I'm leaning towards the Air Vent 500 from Nicro. However, this style vent requires winds on deck to draw air into the cabin. Any thoughts?

I have one of these. They work. You get 2 fan blades - one for intake, or use the other one for exhaust. Here's a link to one on e-bay - New 8.5" SS Solar Vent w/ Battery for Boat, RV, etc. - (eBay.ca item 220370976753 end time 08-Mar-09 22:37:38 EDT)

They work well, but I think at least two are necessary for them to function effectively, one intake, one exhaust.

I have Nicro Day/Night vents, I have had issues with the batteries not lasting very long (6 months).

I replace my passive vent with a Nicro solar unit over 10 years ago. Big improvement. Batteries (NiCad C size) seem to die after about 4 years.

They Work

We had one on my father's 31 foot Irwin. It was installed about 15 years ago. No batteries, just ran when the sun hit it. The cabin was kept nice and fresh, even when it was closed up. No musty smell or stagnant air problems.

I am planning on installing one on my Ericson this summer.

Thanks for all the replies. Looks like it might be worth my money to install one or two.

T37Chef - Great deck pictures! I love the view of the curved rails! Looks like you've got plenty of ventilation with 4 dorade boxes/vents and two solar Nicro's.

I have two of the Nicro solar powered vents—one intake, one exhaust. Installing them dropped the closed boat cabin temperature at least 10-15˚. The newer ones have a sliding part to close them off from water intrusion, but will still leak a bit if waves break over them on the deck.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Yes, the solar powered units are a bunch better than the passive vents. We have found that changing to NiMH batteries (instead of NiCd) improves their longevity quite a bit.

In addition to the solar vent installed in the head (exhaust mode) I burn a hundred watt light bulb 24/7 in the salon. I've had zero issues with mold,odors or moisture.
