How Much Does It Cost to Register a Boat in Maine?
In Maine, boat registration is handled by the Maine Inland Fisheries & Wildlife (town agents) and renews annually. The fee is a flat $46 per year. 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.
