I have a 272 O'Day and the water in the lake is dropping to the point I have to move away from my dock. The lake officials are allowing boat owners to anchor their boats in front of their homes as long as the boat is lighted. I would like to double anchor the boat to restrict the movement, but I am lost! Is this possible? This will be my first time to anchor a boat out in the water. I would still like to tie onto my dock as a safety? Also, what is the best way to light the boat without draining the batteries. I can run a 120 volt line to the boat or keep a battery on the dock and run a line to the boat. I do need help! This is for a 45 day temporary anchoring according to the officials.
