Inside heated in Michigan I can't imagine the humidity is very much at all, i know it's extremely dry in my barn when the heater has been running for a while. It can't hurt but you should not need it. I think a fan running with all hatches and drawers opened up is more effective at keeping mold away than any kind of damp rid product. Make sure to open anchor locker hatch and remove all the rode so it can dry. Get a humidistat if you want to know for sure.
