I fish the Potomac River here in Virginia and have had a lot of success this summer and fall with big blues. Unfortunately, the weather has turned cold and I have winterized my boat, but I'm dying to get back on the water. I was wondering what type of boat maintenance and care is required when fishing in winter. I have a 21' bow rider with an inboard motor and just don't know how to prevent freeze damage. Normally, my fishing is done with the first freeze. I'd love to extend the season. Any tips you can offer are much appreciated.
