We watched fireworks from my boat this past July 4th, and it was about 97 degrees with no wind that night. We were roasting while just floating among about 100 other boats. I turned on my heater without the engine running, and in less than 2 or 3 minutes, it was like having two fans blowing ambient air. It didn't take long for everyone to start fighting over who would hold the two ducts! Made me think that Skiers should have a damper option to blow cold or hot air in those heaters!
