John, that is more along the line of what I am after; one unit to deploy, retrieve, and store my longlines. I suspect, since you state that it sits out of the way in a recess in your boat, that you have a system to minimize clutter and maintain order amid the "organized chaos" of setting and retrieving 7-10 dozen decoys. The barn bucket works fine and can be used as a receptacle for dead birds. Mark Ronger always maintained that he had fewer issues with frozen lines on a reel. Up until this winter, I never thought extreme cold could be an issue while hunting open water anymore...
So far, I found a hose reel that has a large round nob on the spool and its dimensions are about right... The first hose reel Yash posted is really nice, but a little too small in diameter for my needs. Do you have a picture of your unit or a manufacturer and model number for it?
