Boat heater (yet again)

Many Marinas have small print in their winter storage contracts prohibiting any type of heaters- gas, propane, diesel or electric that run unattended. Marina fires are the main reason, and where I keep Candy Cane, they are stored so close, that if one burns, the whole row will go. Besides, I take everything off the boat that could freeze in the fall, and just cover the old girl to keep water from getting in the cockpit and bilge. My $.02 worth.
