My thought was to pull heat off the engine much like the radiator
system in a car.

I have one of their "1H" models in my ski boat. Works great! Even in a
totally open ski boat you can get enough heat out of the vents to keep the
driver warm and toasty. The vents pull out and extend on hoses and you will
often see the observers covered in a blanket with the heater vent tucked up
underneath keeping them warm as well. I am sure that if you had any kind of
enclosure you could get enough heat to keep the cabin reasonably warm.

This is a curious and somewhat confusing image. An open ski boat,
towing a skier and the driver/observer huddling under blankets with
hoses from the heating duct to warm up.

And I thought horse owners were nuts.

Mrs. E excepted of course. ;)

You have to be running, of course.

Of course. :)

If you want heat while the engine is off then I would recommend a small
portable propane unit. I have a propane heater similar to this one:
http://www.mrheater.com/productdetail.asp?id=675 (the double head) that I
used to heat the flybridge of my 36' Carver. I never used both burners at
one time on the boat, and often I had trouble getting turned down low enough
so that it didn't roast us out. If you use something like this take extra
precautions that it is tied down and can't possibly tip over.

Part of the exercise is not to vent an enclosed space other than
ambient drafts.

However, I appreciate the info and I've got it in my to check out
later bookmark.

Thanks.

By the by, just kidding about the skiing.

Not!! :)
