A very practical problem is windshield fogging. This happened on my boat one
cool evening this Fall, and after I realized it wasn't getting foggy
outside, I had my daughter up on the foredeck wiping the windows constantly
while I sponged them off inside - just so we could see. The amount of sudden
condensation was formidable. (Trojan 26.)

Is general pilothouse heating adequate for this? I suspect not. Anyone heat
their windshields, the way the "defrost" setting works in an automobile?

Howdy, Charles,

I've never seen a window defogger setup on a boat. Automotive
defogger/defroster systems use heat plus run the A/C unit to remove the
moisture that is condensing. I recall having cars without air
conditioning and the heat only defogger was not as effective.

An exotic solution would be having your windows coated with transparent
but conductive coating such as Indium Tin Oxide and then pass current
through the coating to heat the windshield. Military and commercial
airplanes use this technique on many of the cockpit display panels and
windshields. Also, I wonder if there is an after market automotive thin
wire defroster that could be applied to the windows, similar to the
electric heater wires in the rear windows of most cars.
