Which Boats Require Registration?
Requirements for vessel registration vary from state to state. In Montana, a boat owner must have the title (Certificate of Ownership), the boat registration (Certificate of Number), and proper decals to legally operate on Montana's waters. Exceptions to registration requirements are:
- Non-motorized sailboats less than 12 feet long and all manually propelled vessels
- Vessels registered in other states using Montana waters for 90 consecutive days or less
- Vessels documented with the U.S. Coast Guard (USCG)
