Rhode Island Boat Registration

Rhode Island is a title state — the DEM FAQ states it plainly: "Please remember Rhode Island is a title state." Under RIGL §46-22.1-3, any vessel more than 14 feet long must be titled; vessels 14 feet in length or less are not required to be titled. Titling is separate from registration, and both are handled at the DEM Office of Boat Registration & Licensing rather than the DMV. Notably, even a non-motorized canoe or kayak over 14 feet must be titled — and because any boat over 12 feet must be registered regardless of propulsion, it needs a registration too.

Federally documented vessels are the main titling exception: because the U.S. Coast Guard Certificate of Documentation is the ownership record, Rhode Island does not issue a state title for a documented vessel. A documented vessel used in Rhode Island still must be registered, though — you file a documented-boat registration application with a copy of the USCG documentation in the owner's name. This is the classic "documented but not titled" arrangement explained in state registration vs USCG documentation.

Rhode Island ties its hull identification number (HIN) handling to the federal U.S. Coast Guard standard. When you register or title a boat, DEM requires a pencil tracing of the actual hull number so the HIN can be verified against your paperwork — the tracing is a listed requirement for both new and used boats, and it exists specifically "to conform to USCG requirements for verification of hull numbers."

For a factory-built boat made after 1972, the HIN is the 12-character code the manufacturer affixed to the hull; it must match the bill of sale, MSO, and title exactly. If a used boat arrives from another state with paperwork that shows a partial or malformed hull number, the pencil tracing is how DEM confirms the true HIN before Rhode Island will title and register the vessel.

Homemade boats have no factory HIN. Rhode Island handles these through the DEM Division of Law Enforcement (401-222-3070), which inspects the finished boat; you also submit build-material receipts (with sales tax paid), a photo of the completed boat, and a notarized statement describing cost, construction, and plans, after which a hull number is assigned. Decode any existing hull number first with the HIN decoder to confirm the manufacturer and model year match the paperwork.

Rhode Island boat registrations are biennial and expire on a fixed date, not the owner's birthday: the registration year runs from March 1 through the last day of February of the following year, so a two-year registration expires at the end of February. Boats over 30 feet may opt for a one-year registration at half the biennial fee. Renewals (and duplicate-decal requests) have moved to the Rhode Island Outdoors (RIO) portal at rio.ri.gov — you first request a RIO Customer Number for your registration account, then renew online; boat registration profiles are separate from any existing RIO hunting/fishing account. New registrations, however, can still only be obtained in person at DEM's Boating and Licensing Office. The outboard motor registration is a one-time item and does not renew.

Non-motorized canoes and kayaks 12 feet or shorter are exempt from registration, as are houseboats as defined in RIGL 44-5-25.1. Any boat with propulsion machinery of any kind must be registered regardless of size — federal law (46 U.S.C. § 12301(a)) requires a motorized vessel to be registered in the state where it is principally operated, which is why even a motorized canoe or kayak must be registered. Non-residents do not have to register in Rhode Island unless the boat's principal mooring area (more than 90 days per year) is in the state. Titling has its own exemptions under RIGL §46-22.1-3 (vessels 14 feet or less), and federally documented vessels are exempt from state titling but must still be registered. Note the size split for paddlecraft: 12 feet or less, nothing required; over 12 feet, registration required even without a motor; over 14 feet, registration plus a title.
