Cost Per Day of Use

Cost Per Day Is the Figure Nobody in Yachting Quotes

Cost per day of use is the only ownership figure that answers the question a buyer actually asked, and no part of the yachting industry publishes it. Brokers quote a purchase price. Marinas quote a rate per metre. Management firms quote a percentage of vessel value. None of them divides by days aboard.

The division is trivial arithmetic and the result is uncomfortable, which is a sufficient explanation for its absence from sales material.

This is the final part of a series building the cost of owning a yacht from published documents. Parts two, three and four priced the berth, insurance and the yard bill from tariffs and datasheets. Part five priced depreciation. This part divides the total by a number that comes from a government survey rather than from anyone selling a boat.

What the Annual Stack Adds Up To

The annual cash stack for a fifteen-metre yacht can be assembled entirely from published figures, and it lands between €55,650 and €114,150. Marina di Ragusa's 2026 price list charges €6,150 for an annual fifteen-metre berth.1 Fraser Yachts puts comprehensive marine insurance at 0.5 to 2 per cent of vessel value, which is €4,500 to €18,000 on a €900,000 hull, and maintenance at 5 to 10 per cent of purchase value, which is €45,000 to €90,000.2

Two large lines are missing, and neither can be sourced the same way. Fuel depends on distance travelled, and no published tariff supplies it. Professional crew, at this size, is usually absent or seasonal.

The stack also excludes depreciation, which part five of this series priced at €90,000 to €180,000 in year one alone. Every per-day figure below is therefore a floor. It prices the cash that leaves the account, not the value that leaves the hull.

How Many Days a Boat Is Actually Used

The only large public dataset on how often boats are used is the United States Coast Guard's National Recreational Boating Safety Survey, and its numbers are well below what most buyers assume. The 2018 exposure survey found that boats operated that year went out on the water a total of 471.8 million days, and that across all owned boats the average was 19 days: 29 days for motorised boats and 12 for human-powered ones.3

The arithmetic is internally consistent. The same survey estimated 25.2 million boats owned across 14.5 million households, and 471.8 million divided by 25.2 million is 18.7 days.3

The survey also found that a single outing lasted an average of 3.8 hours, with 2.3 people aboard.3 The earlier 2012 round of the same programme reported that boats were out on the water an average of about 11.3 days and 4.5 hours per day.4

The Division That Reframes the Purchase

Dividing the published annual stack by the published day counts produces the figure the industry does not quote. The table runs the €55,650 to €114,150 range across five day counts, each taken from a named source rather than assumed.

At the 2018 all-boats average of 19 days, a €900,000 fifteen-metre yacht costs €2,929 to €6,008 for every day somebody is aboard it.

A Third of Boats Never Left the Dock

A third of owned boats did not go on the water at all in the survey year, which is the most consequential single fact in this article. The Coast Guard's 2012 round found that approximately two thirds, 66 per cent, of the 22.2 million recreational boats owned in the United States were operated on the water at least once that year.4

The remaining third generated no days of use. In most cases they still generated a berth fee, an insurance premium and a maintenance liability.

For those boats the cost per day of use is not high. It is undefined, because the denominator is zero. That is the failure mode this series has been circling since part one, where the purchase price is the smallest number: the operating stack recurs whether or not the vessel moves, and nothing in a conventional ownership structure adjusts when the owner's diary does.

Charter Programmes Cap Owner Use at Twelve Weeks

Charter management programmes publish an owner-use allowance, and that allowance is the industry's own view of how much a working owner will realistically use a boat. The Moorings' guaranteed income programme, whose terms page was last modified on 6 August 2026, gives owners up to 12 weeks of annual use across its own and Sunsail's bases, on their own hull or an equivalent sister ship.5

Twelve weeks is 84 days. Catamaran Guru describes the same band across the larger operators at 8 to 12 weeks, and caps the lease-purchase variant at a maximum of eight weeks of reciprocal use worldwide.6

The ceiling is the instructive part. The most generous published owner allowance in charter management is 84 days a year, more than four times the Coast Guard's 19-day all-boats average. A buyer who expects to be aboard more often than that is planning to exceed what the charter industry treats as generous.

The Superyacht Evidence Points the Other Way

Superyacht evidence points firmly in the opposite direction, and it belongs in this article rather than out of it. The Crew Report's Superyacht Golden Ticket survey, published by SuperyachtNews on 13 July 2015, asked more than 1,000 crew members from 655 yachts how long their owner spent on board each year.7

Only 8 per cent of crew said their owner was aboard for less than two weeks a year, and 79.7 per cent said more than one month. Owners were most likely to spend between two and three months aboard, and 17.5 per cent of crew reported owners on board for more than five of the twelve months.7

The reconciliation is crew, not length. A permanently crewed fifty-metre vessel is a residence that happens to have a berth. An uncrewed fifteen-metre production yacht is a possession that consumes the owner's own time to use at all. Utilisation follows who runs the vessel.

Utilisation Decides the Structure, Not Price

Utilisation, rather than purchase price, is what decides whether an ownership structure makes sense, and it is the variable almost nobody underwrites before buying. The per-day figures above move by a factor of more than seven between 11.3 days and 84 days on an identical hull carrying an identical cost stack. Nothing about the vessel changed. Only the denominator did.

That is the whole argument for placing a hull into charter rather than leaving it on a berth. A vessel earning on the days the owner is not aboard has a different denominator, and under a programme such as The Moorings' the operator also absorbs berthing, maintenance, insurance and repairs, which removes most of the numerator as well.5

It is also the argument behind fractional yacht ownership and behind pooled charter fund structures, both of which start from the observation that a yacht used 19 days a year has 346 idle ones.

Where This Analysis Is Weakest

Four limitations qualify everything above. The first is fleet composition. The Coast Guard survey covers the entire United States recreational fleet, in which open powerboats, kayaks and canoes vastly outnumber fifteen-metre cruising yachts, so a 19-day average across 25.2 million boats says little about any one Mediterranean hull.

The second is that no equivalent European figure was found. No public survey reporting days of use per owned boat in the United Kingdom or the European Union surfaced in this research. Where no primary figure exists, this series states the absence rather than estimating one.

The third is the 2012 denominator. The Coast Guard's report states that boats were out on the water an average of about 11.3 days without making explicit whether the denominator is all boats owned or only those operated, so that row of the table should be read as the bound it is.

The fourth is the cost stack, which mixes a Sicilian berth tariff with a brokerage's global percentage bands and excludes fuel, crew and depreciation. The same caution applies to catamaran and monohull cost differences and to the wider ownership cost breakdown. Whether the arithmetic supports ownership at all is taken up at is a yacht a good investment.

HelmShare publishes this analysis because the same operating stack sits underneath a charter fund. Returns from any such structure are targeted rather than promised, and capital is at risk.
