I have two corded remotes at the helm. One is a ZFMarine remote to control the thrusters and throttles on a 25' cord. I comes in handy to walk out the pilothouse doors when docking. The second is a autopilot remote on a 25' cord. Usually both remotes are velcroed to the helm and the cords are coiled and velcroed or laying on the floor.
I am trying to find a better way to store the cables and keep thinking something like the cord retractor on my wife's vacuum cleaner. Mount it in the helm cabinet.
I have looked at several repair manuals for vacuums and every reel I find is passing the power through rotating disks and there are only 3 contacts.
