St Joseph, MI. The marina pumps my holding tank and winterizes the engine for a hundred bucks when they pull the boat for winter storage. I drain the fresh water system, put in 3 gallons of rv antifreeze and run it out of all faucets. I used to have the boat shrink wrapped at $300 a year but Several years ago I had a winter cover made by Ship Shape Canvas in Duluth, MN. (I have no financial interest, just a happy customer.). The cover was somwhere around $700 and paid for its self in two years. I just called them and sent some measurements they requested and in a couple of months had a really nice winter cover. I repaint the bottom prior to putting on the cover. I charge then leave the batteries on the boat.
