Boat Ownership Costs
The True Annual Cost of Owning a Boat
Published April 26, 2026
Researching marine repair costs, ownership expenses, and protection plan options for boat owners.
The sticker price of a boat is the first cost — and rarely the largest one. Owners who plan only for the purchase often find themselves spending another 8–15% of the boat's value every year just keeping it operational.
Annual ownership costs by boat size
| Boat size | Typical annual cost | Driver of cost |
|---|---|---|
| 18–22 ft outboard | $2,500 – $5,500 | Storage, insurance, fuel |
| 24–30 ft outboard / I/O | $5,500 – $14,000 | Slip fees, maintenance |
| 32–42 ft cruiser | $15,000 – $40,000 | Dockage, generator, AC |
| 45–55 ft yacht | $45,000 – $95,000 | Crew, electronics, repairs |
| 60 ft+ yacht | $100,000+ | Everything scales |
The five biggest line items
- Slip / storage: $1,800 – $40,000+/year depending on region and length
- Insurance: 1–2% of boat value annually
- Maintenance: ~10% of boat value annually for boats >5 years old
- Fuel: $1,500 – $25,000+ depending on use and engine type
- Repairs: Highly variable — see our boat repair cost guide
Where extended marine warranties fit
For boats older than 3–4 years, the repair line is the single biggest unpredictable cost. A boat warranty plan converts that variable expense into a fixed monthly cost. Owners who finance their boat almost always come out ahead by adding warranty coverage to the loan rather than absorbing a $15,000 repair in cash later.

Hidden costs most buyers miss
We cover these in detail in hidden costs of boat ownership, but the most commonly missed items are:
- Bottom paint every 1–2 years
- Electronics updates every 5–7 years
- Sea trial / haul-out / survey for warranty claims
- Winterization and shrink-wrap in cold climates
- USCG required equipment replacements
Bottom line
Plan on 8–15% of the boat's value per year as a working number. If that math still works for you, the next step is locking down the unpredictable parts — and that usually starts with a warranty quote.
