The fan I use, which puts out nearly 150 CFM of air if I remeber correctly, is a Delta Electric Inc. (or just Delta as they are known) model AFB1212VHE 12VDC Brushless .90 Amps max current draw. I use them with PWM fan motor controlers and most of the time they stay set at about 150ma, which puts out a nice breeze but is low power. There are various types of controlers, but the PWM type is the best because it keeps the fan running at slow speeds better and it doesn't burn up extra power at lower setting, it only uses the power needed unlike other types or a resistor. The biggest drawback to them is they can make the fan hum a bit on low settings.
One other note about fastening to 'glass with epoxy...it is a good idea to first coat the wood blocks you will glue down with epoxy and let it set, as if not if the wood absorbs enough moisture it will de-bond and come loose. Myself when I used to go sailing in cold weather, I just wore a good set of oiles, never a PFD unless it was dark and rough and I thought I MIGHT get swept overboard. If I DO use a PFD I prefer my surplus NAVY inflatabes, they are much more rugged and reliable than ANY normal store bought models I have seen even though they are not USCG certified...I used them in the USN though and trust them with my life, the others I have are just for 'show'. Better risk management I think is good jacklines, tether and harness, and tether connecting points...these must be much stronger than you think with very solid backing plates to sustain the shock loads that can happen and not fail or tear through. I do use a harness at night when going fwd if the weather is nasty. BTW I have netting with my lifelines, it has proven to be a very good thing to have as it keeps all sorts of things from being washed or blown overboard. I hate towing a dingy under sail as it slows my boat too much and makes her go to windward much less well, and it also is a big risk of loosing the dingy in rough weather (as when you might need the set up mentioned if you fell over board), they fill with water, get very heavy and either break away or chaff the painter through. My boat is very stiff, she will NEVER capsize (might loose the sails in a terrible un-expected gust, but the rigging would stay put and the boat would prob not go more than 40 degrees...) unless a big breaking sea picks her up and throws her into a trough or something, even then she would right quickly and be a better survival bet than a life raft or dingy (although I DO carry a life raft). A bigger risk for me in rough weather is bruised or broken ribs from when the boat snap rolls and catches me off guard. A dis-advantage of a stiff boat! One other risk in cold weather I found is spray and mist and ice, which coats stuff and then later falls down from the mast or rigging as solid ice and can bean you good, not to mention adding a lot of weight where you don't want it. Brrr...just remembering that is too much for me!
