Most new boats must be registered through the North Dakota Game and Fish Department before they can be sailed.
The boat registration application (available at any boat dealers, county auditors, and at the Game and Fish offices) and proof of ownership, such as a bill of sale, invoice, bill of lading, certificate of origin, or out-of-state title along with appropriate fees can be mailed to:
North Dakota Game and Fish Department
100 North Bismarck Expressway
Bismarck, ND 58501-5095.
The North Dakota Game and Fish Department gives boat owners the privilege to use a 10-day Temporary Watercraft Permit, which can be created online and is free of charge. This can be used till the permanent registration comes.
Boat registration fees range from $12 to $33, depending on the size of the vessel. See here for a more detailed breakdown of the registration fees.
