Just a little bit of heads up for you guys that have towers, or any other type of top on your boat. Keep a good eye on your pipe. Mostly around the base of where it mounts. I have seen them freeze. If you can keep it out of the direct wind, and maybe with the sun beating down on it during the day time hours. There are to many tops out there that won't have some water in the pipes. Every time you drill a hole to mount a light, or push a wire through you are at risk of water collecting in the top. Just keep an eye out.
