Cost of ownership

How Much Does It Cost to Own a Boat?

Boat Ownership Cost Calculator

This free calculator estimates the annual and monthly cost of owning a boat or yacht, from engine service and fuel to dockage, haul-out, and insurance. Cost is driven by size, engines, and usage, not purchase price.

Vessel length & use

1/6

Length and hours anchor most of what a boat costs to run.

Vessel length (ft)

Engine hours per year
Reasonable use is good for a boat. Around 100 to 200 hours a year keeps seals, bearings, and fluids healthy. Routine service still happens once a year no matter how much you use it.

Step 1 · Vessel

How much does boat size affect the cost of ownership?

Length is the single biggest lever on running cost, because almost every marine charge is billed by the foot. A longer hull also carries larger engines, a second generator, and a second air conditioning unit. That is why the calculator starts here.

$30 – $75Dockage per ft, per month
$15 – $30Haul-out per ft, per haul
$5 – $10Hull cleaning per ft
38 ftRough boat / yacht line

Which length do you enter?

Enter length overall, or LOA, the full length of the hull from bow to stern. LOA is the figure marinas and yards use to bill you, so it is the number that makes your estimate match real invoices.

If you only know the model, the published LOA on the YachtWay listing is the right value.

Is it a boat or a yacht?

The words boat and yacht describe the same hulls, and buyers search both. As a rough line, vessels under 38 feet are usually called boats and larger ones yachts.

The running costs follow the same rules either way.

What each foot of length changes

Cost lineHow length drives it
DockagePer foot per month, about $30 in Fort Lauderdale to $75 in Newport
Dry storage or liftRoughly half the local dockage rate, per foot
Bottom paintA per-foot package, repainted yearly in South Florida and every 2 to 3 years elsewhere or out of the water
Haul-out$15 to $30 per foot per haul, plus lay days per foot per day
Bottom cleaning$5 to $10 per foot per in-water cleaning by a diver
Boat wash (topside)$3 to $5 per foot per wash
Generators and air conditioningA second unit is added as length rises
Insurance is the one exception. It follows the boat's value, not its size or usage, which is why it is asked on its own step.

Common questions

Usage

How many hours a year do people run a boat?

The average private owner runs about 100 hours a year. Hours affect only two costs, fuel and the long-term rebuild reserve. Routine service happens once a year regardless, so running 50 hours or 150 hours costs about the same to service.

100 hrsTypical owner, per year
~3 hrsPer outing
36 hrsOut once a month
170 hrsOut every weekend

How do I estimate my engine hours?

A typical outing is about three engine hours: out to an anchorage, time relaxing, then the run home.

Time spent at anchor runs the generator, not the main engines, so it does not add to engine hours.

Is more usage bad for the boat?

No, reasonable use is good for a boat. Around 100 to 200 hours a year keeps seals, bearings, and fluids healthy.

Only near-commercial use, above roughly 320 hours a year, starts to add real wear.

Common questions

The complete picture

How much does it cost to own a boat per year?

The cost of owning a boat is driven by its size, engines, and how much you use it, not by what you paid for it. Two identical hulls with the same engines and systems cost the same to run whatever they sell for.

Size sets almost everything

Most marine charges are billed by the foot, so length is the biggest lever. Dockage, dry storage, bottom paint, haul-out, and hull cleaning all rise with length, and longer hulls carry larger engines and more systems.

Value touches insurance only

Insurance is a percentage of the insured hull value, so it is the one line that scales with price. Everything else follows size, engines, and usage, which is why this planner asks for those first.

Two rpm points are published because burn at 3,500 rpm is 25 to 35 percent lower than at 4,000. The calculator uses the 4,000 rpm figure, the closest published point to a sustained fast cruise.

Downsizing saves less than you think

At 4,000 rpm the Mercury 300 V8, Yamaha F250, Verado 350 V10, and Yamaha F300 all sit within about 1 gph of each other. Real cruise burn across the 250 to 350 hp class is far closer together than horsepower suggests.

The hull moves it about 13 percent

Hull choice alone shifts these figures by roughly 13 percent. The same Yamaha F350 measured 8.6 and 9.7 gph at 3,500 rpm on two different hulls.

Volvo Penta IPS pod service (diesel, per engine)

Where IPS figures come from

Volvo Penta publishes no fuel-consumption data on its product sheets, so these numbers come from builder performance reports generated by Volvo's own engine software. The IPS650 figure is Volvo's own stated cruise point, 10 percent below wide open throttle at about 3,400 rpm.

Two engines share the IPS650 name

IPS650 is sold as both the D6 at 480 mhp and the D8 at 509 mhp. The figure above is the D6, which is the one verified against a performance report.

Every diesel figure is read off the manufacturer's propeller-demand curve at 10 percent below wide open throttle, the cruise definition Volvo Penta publishes and the one point comparable across brands. Figures marked estimate have no published fuel curve: Mercury Racing releases no consumption bulletins, and Yanmar publishes one only for the 8LV370.

What is in each service?

Annual, or 100-hour

Engine oil and filter, fuel filters, lower-unit gear lube, sacrificial zinc anodes, and greasing the mid-section fittings.

Major, at 300 hours or 3 years

Everything in the annual service, plus a water pump impeller kit, fresh spark plugs, new thermostats, and the alternator drive belt.

Electric outboards

No oil or plugs, so service is gear lube, anodes, and the coolant system. Running cost is charging energy, about 25 to 35 kW at cruise billed per kWh, not gallons.

All Mercury outboards listed run on 87 octane regular unleaded.

All cruise figures are cruise, not wide open throttle. Diesels come off the propeller-demand curve at 10 percent below wide open throttle; outboards are given at 3,500 and 4,000 rpm from manufacturer bulletins. At wide open throttle the same engine burns two to three times as much, so a boat driven hard will exceed these numbers.

These are dealer estimates

No engine manufacturer publishes service pricing. Manufacturers publish intervals; the dollar amounts are dealer-set and vary with region and labour rate.

Figures assume shop or dealership labor at $150 to $200 per hour. A mobile technician at your dock typically adds a $150 to $200 call-out fee.

Hours or calendar, whichever comes first

Intervals trigger on running hours or elapsed time, so an owner running 30 to 60 hours a year usually hits the calendar trigger well before the hour trigger.

Every figure is per engine and looked up by model in the calculator. Multiply by the number of engines for the boat's total.

Frequently asked questions

Methodology and sources

How we calculate these costs

YachtWay builds these figures from primary sources, not numbers scraped off the open web. Prices vary by location, vessel age, and usage, so treat the result as a planning range, not a quote.

Service and fuel

Service costs come from authorized repair centers and engine-manufacturer service schedules. Fuel comes from the NautiX engine database at cruise, read off the manufacturer's propeller-demand curve.

Storage and insurance

Dockage and haul-out rates are gathered from marinas and yards in each market. Insurance follows standard hull-value percentages.

Labor assumptions

Shop and dealership labor is assumed at $150 to $200 per hour. A mobile technician who comes to your dock adds a call-out fee on top.

A note on these estimates

This calculator is a planning guide to help you understand the shape of what a boat costs to own. It is not a quote or a formal appraisal. Real costs vary with location, the vessel's age and condition, and how you use it, and it does not include a professional management company, which many owners choose to add. No model can account for every variable, so please treat these figures as an informed starting point rather than a precise total. Our numbers draw on authorized repair centers, engine manufacturer service data, and pricing shared by dealers on YachtWay. For decisions that matter, confirm the specifics with a surveyor, broker, or service center.
