California Boat Registration Fee Calculator
In California, boat registration is handled by the California DMV and renews every 2 years. The fee is a flat $20 per cycle. Non-motorized craft like kayaks and canoes are generally exempt (check local rules for sailboats). Boats with motors — including trolling motors on otherwise unpowered craft — almost always require registration.
