Yes, it does. According to the Michigan Department of State, “the U.S. Coast Guard Certification of Documentation (CG-1270) serves as proof of ownership. However, documented watercraft must obtain a Michigan watercraft registration at the regular fee.” That said, “the registration (MC) number does not have to be displayed on the vessel.”
When submitting a WR-11L registration application, attach copies of your documentation papers. A copy of the owner’s application for documentation, showing it is in process, is allowed, on account of the documentation process potentially taking up to six months in the state.
