Missouri Boat Registration Fee Calculator
In Missouri, boat registration is handled by the Missouri Department of Revenue and renews every 3 years. The fee is based on boat length — from $25 for the smallest class up to $150 for the largest 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.
