Hello again from Capt. Pete of "My Alibi". I'm interested in hearing anyone's suggestions for the most efficient and safe metheod of mantaining comfortable cabin temperature for overnighters aboard. Problems to consider are: one battery aboard which runs everything from outboard starts, to lighting, radio, depth, and stereo. We don't want to drain the battery. And we want no fumes. We have lil people as crew most of the time, so safety is the priority of course.
