I went out on a lake yesterday, temp 30, wind easterly at 10-15. I intentionally did not wear thermal underwear, just heavy hunting jeans, chamois shirt, leather boots. I wear my life jacket underneath my coat. I did all this because I wanted to take my youngest grandson today in similar conditions, and he doesn't have all the stuff like I would normally wear. I wanted to see what it would be like for him, and after doing so, decided not to take him today, until I can get him the proper clothing. The wind was brutal. My feet and hands were the coldest. I had gloves for when I was driving or sitting, but to bait up, etc, I was bare-handed. I don't think my fingers all warmed up until I was back home. Just imagine how it would be for a young kid not properly dressed. I need to do something beyond just having warmer clothing for him when I do take him. Question is: What do some of you use or do to stay warm when fishing from an open boat (center console, in my case) in the winter? Does anyone use heaters, hand warmers, etc? I've seen shelters built on some larger boats, but mine isn't large enough for something like that.
