Iowa Boat Registration Fee Calculator
In Iowa, boat registration is handled by the county recorder (Iowa DNR system) and renews every 3 years. The fee is based on boat length — from $28.15 for the smallest class up to $155.65 for the largest per cycle. Unpowered craft such as kayaks, canoes, and sailboats must also register. Boats with motors — including trolling motors on otherwise unpowered craft — almost always require registration.
