Registration

Boat owners must register their vessel with the Department of Natural Resources. Vessels registered in Iowa, must display their current registration decals and the Iowa issued registration numbers provided by the County Recorder. In addition, the operator must carry the registration certificate on board. Registrations must be renewed every three years and are nontransferable. These can be acquired starting January 1st of the new registration cycle and are valid for three years.
