Yes, they do. If you operate a documented vessel on Wisconsin waters, the vessel must also be registered in Wisconsin. You have to do this if you have used the vessel in Wisconsin for more than 60 consecutive days or if Wisconsin is the state of principal use for your vessel.

Yes, it does. Coast Guard documented vessels that have been in North Carolina for more than 90 consecutive days must be registered.

Yes, it does. From Title 46 of the Code of Federal Regulations, all USCG documented vessels, so as to fulfill the name and hailing port marking requirements, must have a name.

No. In fact, a vessel that has been documented cannot also hold a state title. Vessels cannot be titled and registered with the USCG at the same time.

This endorsement is for any vessel that engages in interstate or international commerce. It serves to certify the ownership and registration details of the vessel to ensure it can be identified in case of an emergency, or if there is ever a dispute regarding its provenance. USCG documentation numbers are permanent and never expire. This means that a vessel with a USCG documentation number can retain it in perpetuity, without the need to renew or reapply for a new one. This is an important feature of USCG documentation as it enables potential buyers to check the authenticity of vessels they may purchase, by verifying the history associated with the vessel's documentation number.

Yes. Any NVDC documented vessel in the state of Washington has to also be registered with the state.

If a vessel has been USCG documented, it does not need to be registered with any state. Documentation is accepted by all states as evidence of ownership, which negates the need for registration. However, if there are changes in ownership or the vessel is used in interstate commerce, registration may still be necessary to comply with certain laws and regulations.
