Registration, titling, and HIN rules are set by each state — while federal USCG documentation is a separate national system. These guides cover the state side, and how the two overlap for larger and documented boats.
Most recreational boats are registered with the state where they are used — you get a bow number, a decal, and usually a state title. A separate federal system, USCG documentation, applies to vessels of at least 5 net tons and is required for those engaged in coastwise trade or the fisheries. The two overlap: a documented vessel is not state-titled, but many states still require it to be registered.
If you are not sure which applies to your boat, start with state registration vs USCG documentation.
More states are being added. Each guide is individually researched against the state agency's current rules before it is published.
