Yacht Ownership Costs

The Purchase Price Is the Smallest Number

The question "how much does a yacht cost" is almost always answered with the wrong number. Brokerage listings publish the acquisition price, buyers finance against it, and the entire industry's marketing apparatus is organised around it. But the purchase price is a single event. Everything after it recurs annually, in cash, for as long as the vessel is owned, and in most cases the cumulative operating cost overtakes the purchase price well before the owner sells.

The folk rule circulating in every brokerage blog is that annual running costs come to ten to fifteen per cent of purchase price. That rule cannot be traced to any surveying body, owners' association or insurer. It appears in commercial content, is repeated between commercial content sites, and has no identifiable origin. What can be sourced is a narrower claim, and it is not the same claim. Boat Trader, part of Boats Group, advises owners to budget roughly ten per cent of a boat's value annually on routine maintenance alone, which on a $50,000 boat is about $5,000 a year 1. Maintenance is one line. It is not the total.

The same Boat Trader guide publishes a full sample annual budget for that $50,000 boat, and the arithmetic on their own table is more revealing than the rule of thumb it sits beside. Insurance $500 to $1,000, storage and mooring $2,000 to $10,000, routine maintenance $5,000, fuel $2,000 to $10,000, dockage $500 to $1,000, supplies $300 to $800, memberships $149 to $1,000. Summed, that is $10,449 at the low end and $28,800 at the high end, before the emergency reserve of ten to twenty per cent of value that the same guide recommends holding separately 1. Expressed against the purchase price, the published budget implies annual running costs of twenty-one to fifty-eight per cent, not ten to fifteen.

That spread is not sloppiness. It is the honest answer. The running cost of a yacht is dominated by three variables that have nothing to do with what was paid for it: where it is kept, how far it moves, and how old it is. A fifty-foot boat in a municipal marina in the Adriatic and the same boat in Monaco are the same asset with different cost bases, and the difference between them is larger than the difference between most vessel classes.

The rest of this article builds the stack from published tariffs rather than estimates, at three vessel sizes: fifteen metres, eighteen metres, and twenty-four metres. Every figure below comes from a document a marina, an insurer or a local authority has put in the public domain. Where no primary figure exists, that is stated rather than filled in.

The Berth Sets the Floor

Berthing is the largest fixed line in most ownership budgets, and it is the line where published data is most available and least used. Four tariff cards, from four jurisdictions, describe the range.

At the expensive end, Monaco charges a vessel of 18.00 to 18.99 metres €193.20 per day in high season, or €4,062.00 per calendar month, VAT included. A vessel of 24.00 to 25.99 metres pays €276.00 per day and €5,661.60 per month in high season, falling to €189.60 and €3,460.80 in low season 2. Six months of high season plus six of low, at monthly rates, comes to €54,734.40 a year for the twenty-four metre boat on the published card. That is not a quotation and berths in Hercule are not freely available, but it establishes the ceiling.

Athens Marina publishes annual rates and they are roughly a quarter of that. A fifteen metre vessel pays €14,670 a year, a sixteen metre vessel €17,936, and a seventeen metre vessel €19,839, all before Greek VAT of twenty-four per cent 3. Two provisions on the same card matter more than the headline. First, any vessel under fifteen metres is charged at the fifteen metre rate, so the effective cost per metre rises sharply below that threshold. Second, a stay of ninety consecutive days or less is charged at one three hundred and sixty-fifth of the annual fee increased by a further one hundred and ten per cent per day 3. Transient berthing costs slightly more than twice the pro-rata annual rate. An owner who does not commit to a full year pays for the flexibility at a rate few budgets anticipate.

The most under-reported constraint is not price at all. Le Port Vauban in Antibes, the flagship marina of the Côte d'Azur, restricts its ordinary annual contract to vessels under 12.99 metres in overall length and 4.30 metres in width. Since 1 January 2022, anything over thirteen metres must instead take a guarantee of use contract, which secures a berth in a defined port zone for up to twenty-one years in exchange for a financial contribution to the port's building works 4. A forty-five to fifty-five foot boat cannot simply rent an annual berth at Antibes. It must buy into the infrastructure. That is a capital requirement disguised as an operating cost, and it does not appear in any ownership calculator.

Northern European municipal tariffs provide the useful floor. South Dock Marina, operated by Southwark Council in London, charges £634.92 per metre annually including VAT for the year to 31 March 2026, with a minimum charge of eight metres 5. A fourteen metre boat therefore pays £8,888.88. That is a statutory published fee from a local authority rather than a commercial quotation, which makes it one of the few genuinely comparable berthing numbers in the public domain, and it sits at roughly sixty per cent of the Athens annual rate for a similar length.

The practical conclusion for an underwriting exercise is that berth cost varies by a factor of five or more across European cruising grounds at identical vessel length, and that the choice of home port is a larger determinant of annual cost than the choice of boat. Owners routinely select the vessel first and the berth second. The arithmetic argues for the reverse.

Insurance Is a Percentage, the Deductibles Are the Exposure

Marine hull insurance is priced as a percentage of insured value rather than as a flat premium, which means it scales automatically with the asset and cannot be optimised away by shopping. Sun Coast General Insurance, a US marine broker, publishes indicative pricing that is unusually specific for this market: annual premiums for most cruising yachts run between one and five per cent of insured hull value, with the typical owner landing near one and a half per cent. Their published table gives $3,750 on a $250,000 hull, $7,500 on $500,000, $15,000 on $1,000,000 and $30,000 on $2,000,000, with quoted ranges around each 6. These are broker guidance figures rather than underwriting data, and they should be read as such, but they are the most granular publicly available.

Two findings on that card cut against intuition and are worth stating plainly. The first is that larger yachts generally pay a lower percentage of value, not a higher one. The broker attributes this to underwriting economies of scale and to the fact that owners at the top of the market tend to have professional captains, formal hurricane plans and more disciplined risk management 6. Insurance is one of the very few cost lines in yachting that exhibits genuine economies of scale, and it is therefore one of the few that favours a fund or fleet structure over an individual owner on arithmetic alone.

The second is geographic. Vessels kept in named-storm exposure, principally Florida and the Gulf, routinely rate at three to five per cent of hull value rather than the one and a half per cent average 6. That is the single largest geographic factor in the premium, and it converts a Caribbean winter programme from a revenue decision into an insurance decision. A fleet that moves seasonally between the Mediterranean and the Caribbean is making an underwriting choice every year, whether or not it recognises it as one.

The exposure that is systematically under-modelled is not the premium but the deductibles, and there are two. Yacht policies typically carry a standard deductible of one to two per cent of insured value, and a separate named-storm deductible applying only to losses caused by named tropical systems, which is usually five to ten per cent of insured value 6. On a €1,000,000 hull, a named-storm deductible at the upper end is €100,000 absorbed by the owner before the policy responds at all. Two policies with identical premiums and different named-storm deductibles are not comparable products, and the difference only becomes visible in the year it matters.

For the three tiers, applying the broker's typical percentage rather than a quotation: a fifteen metre sailing yacht insured at €350,000 implies roughly €5,250 a year, an eighteen metre motor yacht at €900,000 roughly €13,500, and a twenty-four metre vessel at €3,000,000 roughly €45,000, with the caveat that the larger hull would in practice rate below one and a half per cent. Capital at risk in this asset class is not an abstraction; it is a deductible schedule.

The Yard Bill Is Engineered to Compound

Haul-out, hard standing and yard labour are the costs owners underestimate most consistently, partly because they are episodic and partly because the tariff structures are deliberately designed to penalise delay. South Dock Marina publishes its yard schedule in full, and the schedule is instructive precisely because it is a local authority document rather than a sales page.

Lift out or launch is charged at £41.64 per metre of overall length including VAT, so a fifteen metre vessel pays £624.60 each way. Hard standing is then charged on an escalating scale: £2.04 per metre per day for the first thirty days, £2.52 for days thirty-one to sixty, £3.00 for days sixty-one to one hundred and twenty, and £3.72 thereafter, all including VAT. The document states the intent explicitly, noting that boat yard costs increase the longer the boat is in the yard 5. Yard labour is £77.88 per hour including VAT.

Run that against a realistic refit. A fifteen metre vessel ashore for a full winter, one hundred and twenty days, pays 15 × £2.04 × 30 plus 15 × £2.52 × 30 plus 15 × £3.00 × 60, which is £918.00, £1,134.00 and £2,700.00, totalling £4,752.00 in hard standing alone. Add lift out and launch at £1,249.20 and the vessel has spent £6,001.20 before a single hour of labour, a litre of antifoul or a component has been bought. At £77.88 an hour, a hundred hours of yard labour, which is a modest specification for a winter refit, adds a further £7,788.00. A routine winter therefore lands near £13,800 on published tariffs for a boat many owners would describe as small.

The escalator matters more than the headline rate because refits overrun. A project scoped at sixty days that runs to one hundred and forty does not pay eighty additional days at the day-one rate; it pays them at £3.72 per metre per day, an eighty-two per cent uplift on the opening tariff. Delay in a yard is not merely an opportunity cost against the season. It is a directly priced penalty, and it is priced by every yard that publishes a schedule, not only this one.

There is a second-order effect that is rarely modelled. Because hard standing is priced per metre per day and berthing is priced per metre per year, the two costs run concurrently for most owners. An annual berth holder taking the boat out for a winter refit is generally paying for the empty berth and the occupied hard standing simultaneously. That double running is invisible in any published ownership calculator and it is entirely real in the cash flow.

Depreciation and the 2026 Operating Environment

Depreciation is the largest single cost in yacht ownership and the only one that never appears on an invoice. The best-evidenced public account of its shape comes from BoatUS Magazine, using pricing sourced primarily from J.D. Power. Boats follow an S-curve. A decline of ten to fifteen per cent is common in the first year. Roughly twenty per cent is typically lost by year five, and thirty to fifty per cent by year ten. Depreciation then re-accelerates through the vessel's teens and twenties before bottoming out at between ten and thirty per cent of original value 7.

Two details in that account deserve wider circulation. The first is the explanation for the late-life re-acceleration, which is not simply wear. BoatUS attributes it partly to restrictions on insurance coverage that apply once vessels reach certain ages, often at the twenty, twenty-five and thirty year marks 7. Insurability, not condition, sets the terminal value of an ageing hull. An owner planning a long hold is exposed to an underwriting decision taken by a market they do not participate in.

The second is that size slows depreciation. A twenty foot boat is likely to depreciate faster than a fifty foot boat, because supply is deeper, turnover is faster and the specification ceiling is lower 7. Individual model outcomes vary widely on the same data: a Grady-White Freedom 255 that cost $110,010 new in 2016 carried an average retail value of $83,460 ten years later, a twenty-four per cent decline, not adjusted for inflation 7. That is a strong outcome and it is not the median. It is also nominal, which in a decade of cumulative inflation means the real loss was materially larger than the headline.

Against that, the 2026 operating environment has moved sharply and adversely. The World Bank describes the conflict-related closure of the Strait of Hormuz as the largest oil market disruption in history, with global oil supply falling 10.1 million barrels a day in March and the Brent price rising about sixty-five per cent, some $46 a barrel, by the end of that month, the largest monthly rise ever recorded. The Bank's baseline has Brent averaging $86 a barrel across 2026 and $70 in 2027, with an escalation range of $95 to $115 8. Fuel is a variable cost that scales with use, which means it is borne disproportionately by owners who actually cruise.

The effect is already visible at operator level, and the most useful evidence comes from a source with every commercial reason to say otherwise. IYC, which manages the largest charter fleet in the world, reports that rising operating costs are influencing yacht selection, and that higher fuel prices, provisions and advance provisioning allowances, together with geopolitical uncertainty in the Middle East, are encouraging clients to favour shorter, more localised itineraries and yachts with lower weekly rates 9. The same report notes that the global fleet of yachts over twenty metres now exceeds 2,300 and is growing at roughly six and a half per cent a year, and states plainly that increased supply means more competition 9. More supply, flat to modest demand growth and rising input costs is a textbook description of margin compression, and it is being described by the largest operator in the market.

One number is missing from this section and it should be missing rather than estimated. There is no publicly indexed price series for marine gasoil at Mediterranean berths, and the war-risk and bunker data available for 2026 relates to commercial tankers, a different market with different exposures. Any fuel figure for a private yacht in the current environment is a guess. The direction is well evidenced; the magnitude is not.

Four Weeks a Year, and What Follows From It

Assemble the verifiable lines for the middle tier, an eighteen metre motor yacht insured at €900,000 and kept in Greece. Berthing at the Athens Marina published rate for seventeen metres is €19,839 before VAT, and eighteen metres costs more. Insurance at the broker's typical one and a half per cent is roughly €13,500. A winter ashore on the South Dock schedule, scaled to eighteen metres, is somewhat over £16,000 including a hundred hours of labour. Depreciation on the J.D. Power shape, taking the gentler part of the curve at four per cent a year against a €900,000 asset, is €36,000. Before fuel, before provisioning, before a captain, before management fees and before a single unscheduled repair, the annual cost is comfortably north of €85,000. The purchase price, as promised, is the smallest number in the equation.

Now divide by usage. Owners of vessels in this class, asked honestly, typically use them for four to six weeks a year, constrained by weather windows, school terms and work. At four weeks, the cost above is more than €21,000 per week of actual use, and that is before the largest variable costs have been added. Chartering an equivalent vessel for four weeks, in a market IYC describes as having more supply and more competition than a year ago 9, costs materially less than owning one and carries no residual value risk, no insurability cliff at twenty years, and no exposure to a yard escalator. For an owner whose honest usage is four weeks, ownership is the most expensive available method of obtaining those four weeks.

That observation is what drives owners towards charter management, and it is where the analysis has to be careful rather than convenient. Charter management does not remove the cost stack; it introduces a revenue line against it and adds a management fee, a commission and heavier wear. It converts a consumption asset into an operating business with a fleet manager between the owner and the vessel. Some owners find the trade acceptable. Many discover that a vessel earning charter revenue is not available in the weeks they wanted it, which was the point of buying it.

The strongest argument against every structure discussed here, pooled or otherwise, is not operational. It is the discount rate. A liquid, daily-priced government bond currently offers a positive real return with no crew, no berth, no yard escalator and no named-storm deductible. In 2021 the hurdle an illiquid real asset had to clear was close to zero. It is not close to zero now. Any marine asset structure, including a fund, must clear that hurdle after operating costs, management fees and depreciation before it is interesting at all, and honest underwriting starts by conceding the point rather than arguing around it. Capital in these structures is at risk, targeted returns are targets and not commitments, and the illiquidity is real.

What the published tariffs do establish is that scale changes the cost base in ways an individual owner cannot replicate. Insurance rates fall as a percentage of value as vessels get larger. Yard tariffs are negotiable for fleet volume in a way they are not for one boat. Berths at capacity-constrained ports are allocated to counterparties who commit annually rather than transiently, where the transient penalty at Athens alone is one hundred and ten per cent 3. A fleet spreads a professional shore team across many hulls; an owner cannot spread it across one.

That is the structural observation HelmShare is built on. HelmShare Prime Fund, L.P. is a Cayman Islands Exempted Limited Partnership investing in a professionally operated charter fleet, offered under Regulation S outside the United States to professional, qualified and high net worth investors, with HelmShare LLC (DIFC) as General Partner and Investment Manager. It is one structural answer to the arithmetic above, not the only one, and it is not a substitute for owning a boat if what the reader wants is to own a boat. The question worth sitting with is a narrower one: for an asset whose full annual cost is between a fifth and a half of its purchase price, and whose honest utilisation is four weeks in fifty-two, is ownership the exposure the investor actually wants, or simply the one the market is organised to sell.
