What She Costs to Keep
Ten percent of her value a year is the working rule, and it is close enough to budget from. Here is what sits inside it in South Florida. Every line, at what rate, and three boats added up.
Line by line
Where the Money Goes
South Florida rates, for a boat kept in a marina and used normally. Fuel is the only line you really control; the rest arrive whether you run her or not.
| What | Typical rate | Worth knowing |
|---|---|---|
| Dockage | $25 to $75 per foot, per month | The biggest line, and the widest. Fort Lauderdale rates vary by marina, location and what comes with the slip; an annual contract beats a monthly rate, and moving a few miles off the prime stretch saves real money. Above roughly 100 feet the per-foot rate itself climbs. |
| Insurance | 1 to 3% of insured value, and up | Driven by the boat's age and condition, your experience, your cruising area and your claims history, and it goes above three percent readily enough when several of those run against you at once. Named-storm exposure puts South Florida in the upper half to start with. Budget from a quote on your own boat, not from the range. |
| Fuel | By use, not by year | A twin-engine sportfish at cruise burns around 60 gallons an hour, so a full day out is $500 to $1,500 in fuel. A trawler doing the same distance at 9 knots is a fraction of it. This is the line you control. |
| Routine maintenance | $15,000 to $40,000 on a 40- to 60-footer | Bottom paint every 12 to 18 months, engine service intervals, zincs, air conditioning, detailing. Scales with size and with how hard she is used. |
| Hull cleaning | $150 to $400 a visit | Monthly at least in warm Florida water, or growth costs you speed, fuel and eventually running gear. |
| Haul-out and bottom work | By the foot, at every stage | The annual lift for bottom paint and a look at the running gear. Lift, blocking, wash, paint and every lay day are each priced by length with a yard minimum under them, so this line scales with the boat rather than sitting at a flat figure. Book early: slots at short notice cost more. |
| Operating consumables | $5,000 to $15,000 a year | Oil and filters, generator service, watermaker, electronics updates, safety gear in date, and the small supplies nobody budgets for. |
| Captain and crew | $75,000 to $150,000 full-time | A day-rate captain is $400 to $800. Above roughly 70 feet a full-time captain stops being a luxury; above 100, crew need their own accommodation. |
| The repair fund | 2 to 5% of value, per year | Not a maintenance line, a capital one: an engine overhaul, a generator, an electronics refit, structural work. Set it aside whether or not you spend it, because the year you need it you need all of it. |
Added up
Three Boats, a Year Each
Built from the rates above at their middle rather than their extremes: dockage around $40 a foot a month, insurance at two percent, maintenance and consumables to size, moderate use. A hard-run boat or a premium slip lands higher.
| Boat | Value | Dockage | Insurance | Running | Crew | A year | Of value |
|---|---|---|---|---|---|---|---|
| 50 ft express | $800,000 | $24,000 | $16,000 | $30,000 | None | $70,000 | 9% |
| 70 ft flybridge | $2,000,000 | $34,000 | $40,000 | $55,000 | $75,000 | $204,000 | 10% |
| 100 ft tri-deck | $6,000,000 | $85,000 | $120,000 | $150,000 | $310,000 | $665,000 | 11% |
Fuel is excluded from these totals because it is entirely a function of use. Add it to your own pattern: a day out on the 70 is $800 to $1,500, and on the 50 rather less.
What moves it
Four Things Worth More Than the Rest
Where she sleeps
The same boat on the New River and at a premium beach marina is a five-figure difference every year. Confirm the slip and its rate before you buy the boat, not after.
How often she runs
Counter-intuitively, a boat that is used regularly costs less to keep than one that sits. Systems that run stay healthy; the expensive failures are on the boats nobody turns over.
Her age, and her last refit
A fifteen-year-old hull with a recent refit (tanks done, generators new, electronics current) can run cheaper than a five-year-old boat on original systems reaching their intervals all at once.
Whether you run her yourself
A captain is the single largest step-change in the budget. Below about 70 feet it is a choice; above it, it stops being one.

The Questions Behind the Budget
Tell us the boat you are looking at and we will price her running costs against what owners of that model actually spend, before you commit to her.
(954) 560-2811Is the ten percent rule accurate?
As a planning figure, yes, and it is the right place to start. In practice it moves with size: under 50 feet without crew, six to eight percent of value a year is normal; between 50 and 90 feet it sits close to ten; above 100 feet with full-time crew it runs twelve to fifteen. The rule breaks most often on a boat bought cheap. The costs follow the boat's size and systems, not what you paid for her.
What is the single biggest cost?
Dockage, for almost every owner without crew. In Fort Lauderdale it runs $25 to $75 per linear foot per month, so a 50 footer is $15,000 to $45,000 a year on the slip alone before anything else. On the worked example further up this page, a 50 foot express sits at $24,000 and a 70 foot flybridge at $34,000. It is also the line with the widest spread, which means it is the one most worth working on: an annual contract beats a monthly rate, moving a few miles off the prime stretch saves real money, and above roughly 100 feet the per foot rate itself starts climbing. Confirm the slip and its rate before you buy the boat rather than after, because the same hull on the New River and at a premium beach marina is a five figure difference every year. Once you employ a full time captain, crew overtakes it.
How much should I keep in reserve?
Two to five percent of the boat's value a year, set aside as a capital fund rather than a maintenance budget, and ten to fifteen percent of the purchase price held back for the first season, which is when you find what the survey did not. Owners who spend the last dollar on the boat itself are the ones who end up unhappy with her.
Does a bigger boat cost proportionally more?
More than proportionally, because of the thresholds rather than the feet. Between the thresholds cost rises gently; across them it steps. A captain arrives around 70 feet, crew accommodation around 100, and commercial coding regimes above 79 feet if she is ever chartered. Dockage is per foot and the rate itself climbs at the top end. The worked examples on this page show what that looks like: a $800,000 fifty footer runs about $70,000 a year with no crew, a $2m seventy footer about $204,000 of which $75,000 is crew, and a $6m hundred footer about $665,000 of which $310,000 is crew. As a share of value those are nine, ten and eleven percent, which looks gentle, but the absolute number has gone up almost tenfold for twice the length. The crew line is what does it.
Can I offset any of it by chartering?
Sometimes, and it is rarely the free money it looks like. Charter brings a management company taking a commission, commercial grade insurance in place of your pleasure policy, coding requirements that above 79 feet mean a commercial regime with surveys and equipment to match, crew, and wear that shortens every maintenance interval on the boat. It also changes how you use her: the weeks that charter best are the weeks you most want her, and a boat in a program is committed to dates rather than available to you. It can cover a meaningful share of running costs on the right yacht in the right program, and owners who go in expecting that are usually satisfied. It does not make ownership free, and an owner who buys a bigger boat than they wanted on the assumption that charter will close the gap is the one who ends up selling early.
Budgeting for a Particular Boat?
Send us the listing. We will tell you what that model actually costs to run, what her systems are due, and whether the asking price leaves room for the first season’s list.
What will this boat actually cost you?
The figures above are the shape of it. The answer for one particular boat is narrower than that, and it turns on where she will lie, how you will use her and whether you will run her yourself. Tell us which boat you are looking at and we will work it through with you before you buy her rather than after.
