The short answer
- Utilisation, not price, drives cost per week: the same yacht costs €103,732 a week at four weeks of use and €20,746 at twenty.
- A group of four converts the unused capacity into other people’s money: your 10 weeks cost €10,373 a week instead of €41,493.
- The break-even is mechanical: if you use fewer than 10 weeks a year, you are funding capacity you do not consume.
Cost per week is a usage number, not a price number
Take the median motor yacht 62-85 ft at €2,408,700. Over five years the net cash cost of sole ownership is €2,074,646 on our model. Divide that by the weeks you sail, not the weeks the yacht is available, and the headline price stops mattering.
A yacht is realistically available for about 40 weeks a year once maintenance, yard time and weather slack are removed. Very few private owners of this class sail anywhere near that.

| 4 | €103,732 | €25,933 | 75% lower |
| 6 | €69,155 | €17,289 | 75% lower |

| 10 | €41,493 | €10,373 | 75% lower |
| 20 | €20,746 | €10,373 (capped at 10 weeks) | 50% lower |
Original GetBoat data: 415 euro-converted asking prices of 50–110 ft yachts listed for sale by GetBoat and its partners on 2026-09-20, plus the GetBoat market index (8,474 priced sale listings, 85,489 charter listings). Asking prices, not completed sales. Individual listings are never identified. Model: annual running budget 10% of the yacht price growing 3% a year, resale after 5 years at 72% of the price (per-brand depreciation in the GetBoat market index) less 7% selling costs, 40 owner weeks a year. Excludes VAT, financing, personal tax and programme fees. Illustration, not an offer. A group of four gives each partner 10 weeks a year; usage above that is not available to a quarter share.
Why the two columns converge
At 10 weeks a year the columns are proportional: the sole owner pays four times as much for four times the available capacity. Above that the share simply runs out of calendar, which is the honest limit of the argument — a heavy user should own a larger share or the whole yacht.
Below that line the sole owner is buying weeks and throwing them away. That is the waste co-ownership removes, and it is the only part of the case that our own numbers prove without assumptions about lifestyle.
Measure your real usage before you decide
Count the last three years honestly: nights on board, not intentions. Include the weeks when the yacht was in the water and you were not on it. Most buyers are surprised by the gap between the season they imagine and the season their calendar allows.
Then apply the arithmetic above. If your honest number is under 10, a quarter share of a better yacht will cost less and deliver more boat than sole ownership of a smaller one.
Decision checklist
- 1Nights on board counted for the last three seasons, not estimated
- 2Peak weeks you genuinely need identified by date range
- 3Cost per week calculated on your usage, not on availability
- 4Group size tested against your usage before committing
- 5Charter or guest use of your unused weeks explicitly ruled in or out
- 6Calendar conflicts with other owners discussed before signing
What buyers ask next
How many weeks a year do private owners of this class actually use?
There is no public dataset for private use, which is why we show a range rather than claim an average. Run the table with your own honest count — the conclusion changes at the point where your usage passes the weeks a share provides.
Can I buy more weeks if I need them?
Extra capacity is a question for the specific programme and the other owners, not something arithmetic can promise. If you need more than a share provides every year, price a larger share or sole ownership instead.
