My lake is cooling down--it's dipping down into the forties at night, and the first frost is due soon. Are there any problems that go along with driving a sub in cold water? How cold can the water get before it becomes a problem?
As a cold water state water safety guy, I have to also remind you of the dangers of hypothermia in a swimming retrieve if you lose your boat. A guy drowned in cold water a couple of years ago trying to get his surface model that got away from him in 50 degree water. In fact, there is a saying among water safety experts that you have a 50 / 50 chance of swimming 50 yards in 50 degree water. Even less in cooler water. If you have to go in - get an insulated dry suit or find somebody who has one!
Lecture over.
