How to Sell a Boat Privately in California — 8 Steps

  1. 1Locate the HIN — the 12-character hull identification number is stamped on the starboard (right) transom on all boats manufactured after 1972. California requires this on every bill of sale.
  2. 2Determine registration class — boats under 26 ft register with California DMV only. Boats 26 ft+ may need USCG documentation (federal title) in addition to state registration. Check vessel length and use.
  3. 3Clear any liens — if the boat was financed, request a payoff and lien release letter. California uses REG 227.
  4. 4Gather documentation — current California registration card, state title (if titled), USCG documentation (if applicable), trailer title, engine serial number records.
  5. 5Price the vessel — check NADA Guides (boats), BUCValu, or recent California dealer comps. Factor in trailer condition, engine hours, and recent service.
  6. 6Complete the bill of sale — HIN, vessel make/year/length, engine make/model/serial, trailer VIN (if included), sale price, sale date, both parties' full legal names and addresses.
  7. 7Sign the title or registration — endorse the back of the California registration or title. For USCG-documented vessels, complete Form CG-1340 (notarized).
  8. 8Notify California DMV — buyer must register within 10 days of the sale. Seller files release of ownership with California DMV to remove liability for future fines.
