Estimate bay boat ownership cost in North Dakota
North Dakota’s Insurance Department says the state does not require liability or property insurance for boats on public waters. The full insurance answer for North Dakota — including how this calculator’s planning estimate works — is on the North Dakota boat insurance answer (PWC page) page.
Bay boats sit between a skiff and a center console: skinny water, a modest V, still usually trailerable. The cost surprise is rarely the hull—it is the outboard and how you park it.
North Dakota boating is prairie reservoirs and rivers—especially Lake Sakakawea and the Missouri system—plus smaller lakes. The season is short and this model marks the state cold. There is no ocean coastline.

What makes a bay boat expensive to keep
A bay boat is a fishing hull for bays, sounds, and skinny water: more freeboard than a flats skiff, less of an offshore console. This calculator’s defaults keep it trailerable (about 22 feet, a single mid-size outboard, trailer storage) because that is how most bay boats are used.
Owners shop them as “not a huge center console.” That is true on slip length and often on price. It is not automatically true on fuel. A 150-horse outboard still follows the same SFC math. If you jack the horsepower to run a long commute across a sound, the fuel line looks like any other 150–200 horse gasoline boat.
Bay boats earn their keep when they launch often. They look expensive per outing when they live under a cover for 48 weeks. Use the outing field. If you are deciding between this and a true center console, duplicate the scenario and change type—do not compare dealer payments alone.
- Draft vs horsepower. The hull is for skinny water; the engine may not be. Budget the engine you will actually hang on the transom.
- Trailer life. Default storage is a trailer. A wet slip in a coastal state can erase the “smaller than a console” savings.
- Hours in a chop. Bay crossings in wind are higher-load hours than a lake idle. Raise load factor if that is your use.
- State waters. Sounds, bays, and inland reservoirs are different registration and insurance contexts. See the state block below.
North Dakota rules that change the bill
Agency. North Dakota Game and Fish Department. Official page: https://gf.nd.gov/boating.
Registration and titling. Registration only (not a title state in the CA DMV table). The North Dakota Game and Fish 2026–2028 boating guide states that North Dakota is a registration state and does not issue titles for any watercraft, motor, or trailer. The registration card is the proof of ownership. North Dakota watercraft registration is a Game and Fish product. Owners of motor-propelled watercraft used primarily in the state must register for the three-year cycle. Official 2026–2028 length bands and the ANS fee are in the sourced-facts block on this page.
Sales or use tax (general). North Dakota has a statewide sales tax plus local taxes. Boat purchases are generally taxable. Confirm with the Office of State Tax Commissioner. This page does not quote a rate.
Boating education. Game and Fish requires Boat North Dakota for youth ages 12–15 who want to operate alone a boat or personal watercraft with at least a 10 horsepower motor. The paper home-study course is listed as free.
Water and climate in this model. North Dakota boating is prairie reservoirs and rivers—especially Lake Sakakawea and the Missouri system—plus smaller lakes. The season is short and this model marks the state cold. There is no ocean coastline. This calculator adds a winterization line in cold states. Months-in-the-water and slip-rate defaults are planning assumptions, not a marina rate sheet.

Registration, not a title
The North Dakota Game and Fish 2026–2028 boating guide states that North Dakota is a registration state and does not issue titles for any watercraft, motor, or trailer. Owners of watercraft propelled by a motor and used primarily in the state must register. That includes pedal boats, kayaks, and canoes once a motor is placed on them, and similar motorized products. The registration card is the proof of ownership in North Dakota.

2026–2028 registration fees
Game and Fish lists the January 1, 2026 through December 31, 2028 cycle as $30 for motorboats under 16 feet (and all motorized canoes regardless of length), $45 for motorboats 16 feet and over but shorter than 20 feet (excluding canoes), and $60 for motorboats 20 feet or over (excluding canoes). Fees are prorated. This calculator’s annual registration default is a planning input, not a three-year Game and Fish receipt.

Aquatic nuisance species fee
An ANS fee of $15 is required for each motorized watercraft registered in North Dakota, running concurrent with the three-year registration period and prorated. Motorized watercraft operated on North Dakota waters but not licensed in the state owe a $15 ANS fee each calendar year and must display an ANS sticker.

- Is a bay boat cheaper than a center console in this model?
- Defaults are cheaper because price, horsepower, hours, and storage start lower. Change those inputs to the boat you are shopping. The formulas do not apply a bay-boat discount.
- Should I use wet-slip storage for a bay boat?
- Only if you will pay for a slip. The default is trailer. Switch storage and watch the fixed pile move.
- What costs are included in the all-in monthly number?
- Loan principal and interest (unless the boat is paid for), insurance, slip or trailer storage, winterization in cold states, registration, estimated fuel, and maintenance. Most of this bill shows up whether you launch or not.
- What if the boat is paid for?
- Choose Paid for — no loan. Principal and interest drop to zero. Insurance, storage, fuel, and maintenance still count. Buy vs rent treats the purchase price as cash paid up front.
- Is the loan rate a real quote?
- No. The default APR is an illustration rate, not a lender quote. Enter the rate on an offer you actually have.
- How is fuel burn estimated?
- Gasoline uses 0.50 lb/hp-hr specific fuel consumption and 6.2 lb/gal fuel weight. Diesel uses 0.40 and 6.9. Cruise gallons per hour is wide-open-throttle burn times a load factor (default 65%). This is an SFC estimate, not a sea trial.
- What does year-5 underwater mean?
- If the remaining loan balance after five years is higher than the depreciated boat value (15% the first year, then 10% per year), the loan is underwater in this model.
