Why is PWC insurance a higher percent in this model?

The planning rule is max(2% of price, $250) times the state insurance multiplier, unless you override it. Replace it with a quote.

Do I still winterize a PWC in a warm state?

This model adds winterization only in states marked cold. Follow the manufacturer’s storage steps either way; the dollar line here is a climate switch, not a shop manual.

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.

Estimate personal watercraft ownership cost in Michigan

Personal watercraft are cheap to buy next to a cabin cruiser and expensive to keep as a percent of price. Insurance and maintenance percentages are the highest in this model.

Michigan is a Great Lakes state with four of the five lakes on its borders and a large inland-lake system. Ice, a short season, and trailer or rack storage dominate. This model marks Michigan cold and does not assume a 12-month wet slip.

What makes a personal watercraft expensive to keep

A personal watercraft is a sit-down or stand-up jet boat. This calculator treats it as its own type because insurers and shops do. The insurance floor is a higher percent of price than a pontoon, and maintenance is modeled at 6% of price unless you override it. That is a planning default, not a shop invoice.

Registration and education rules for PWCs are often stricter than for a 20-foot bowrider. Many states have a higher minimum age, a required safety certificate, or both. This page will not invent those ages. Read the official state agency link in the sources line.

Fuel is still SFC math: horsepower times engines times hours. A 110-horse PWC with 30 hours is a different fuel line than a 300-horse ski PWC you ride every warm evening. Storage is usually a trailer or a rack, not a wet slip. If a marina bills you for a PWC dock, put that number in the slip override.

Percent-of-price costs. Insurance and maintenance bite harder on a $16,000 machine than the same percents would on a cheap-looking monthly loan.
Hours. PWCs get ridden in short, high-load bursts. If that is you, do not leave hours at a casual default.
Education and age rules. These are state law, not calculator settings. See the state block.
Theft and tow vehicles. The model does not include a truck payment or a stolen-PWC deductible. Those are still real.

Michigan rules that change the bill

Agency. Michigan Secretary of State (titles and registration) and Department of Natural Resources (boating). Official page: https://www.michigan.gov/sos/all-services/watercraft.

Registration and titling. Titles some vessels. California DMV notes Michigan titles watercraft 20 feet and over and those with a permanently affixed engine. Confirm current cutoffs with the Secretary of State. Michigan watercraft decals and titles are Secretary of State products. DNR publishes the handbook and on-water rules. Length and inboard vs outboard change whether a title is required.

Sales or use tax (general). Michigan has a statewide sales tax. Boat purchases are generally taxable. Confirm with the Michigan Department of Treasury.

Boating education. Operator-age and education rules are state-specific and change. Read Michigan Secretary of State (titles and registration) and Department of Natural Resources (boating) rather than assuming a neighboring state's card is enough.

Water and climate in this model. Michigan is a Great Lakes state with four of the five lakes on its borders and a large inland-lake system. Ice, a short season, and trailer or rack storage dominate. This model marks Michigan cold and does not assume a 12-month wet slip. 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.
