Recently, when living aboard my 18’ Boston Whaler Outrage with Mills Canvas weather system for a week, I had need to operate the boat with the windshield and side curtains up on a muggy, damp afternoon. The inside of the windshield began to fog and as I wiped it down (repeatedly) with a soft terry towel, I thought to myself: I need a small, DC operated fan that can plug into my cigarette lighter and can clamp to my console railing to clear off the windshield. Something like the bus driver used all those years ago when shuttling wet kids to and from school on cold, damp winter days…

I’ve found one, but the quality looks poor, and I don’t think I can select “non-oscillating,” although I’m not sure: koolatron-12v-oscillating-auto-fan.html

I believe this is sold in Walgreen’s stores – which may also be the source of some of my concern re: quality and longevity.

I boat in freshwater, so corrosion is not a major problem. What do you guys use to keep the fog off your windows/windshields and/or canvas?

I bought one of these and only used it once in my cheap Cavalier that the defroster broke. Worked ok for 10 bucks.

This one looks about the same as the kooltron but at less than 1/3 the price.

Dave, I installed a Caframo Bora 748 in my cuddy last year so I can vouch for their quality.

I think what you may want is the Caframo Kona 817, it can be suction cup or surface mounted:

You could use it for sleeping too.

Here are some warmer links. Drat.

Dave - you can get all sorts of DC computer muffin fans at best buy. Screw one to a RAM mount, add wires, and you will be good to go.

Good point, Plotman.

In fact, tell me what size you want Dave and I'll send you one. I have a whole box of them...

Would a DC computer fan move enough air?

I think I'm going to look into the ones that David Pendleton linked to above - they seem designed to be a bit weatherproof.

I have one in the cuddy on my Revenge to keep the air moving if needed when sleeping, it was there when I bought the boat, a little noisy but does the job, it's wired on a cigarette lighter/12 volt plug.

As with most things, you get what you pay for. I was recently in Fawcett Boat supplies in Annapolis and walked past a display with 2, 12v fans. Since it was about 93 degrees outside, I took a second look. The fans looked well made and reasonable quiet (not a rattle-trap). One was about $75 and the other over $100. I think one was a HELLA brand. By contract, the one is West Marine for about $40 was a cheap rattle-trap.

For what you want it for, I think you'd be better off with a purpose-built fan.

The Caframo Kona is weatherproof, has a 12V cigar plug and suction cup mount. Be prepared for sticker shock though, as TransAm points out, they aren't cheap.

My Caframo Bora was $75.00, but it's well-made and has been well worth it thus far.
