Yacht co-ownership maths: what a share of a 50–110 ft yacht really costs

Entry, running costs and five-year net cost of a yacht share across seven 50–110 ft classes, calculated from 415 GetBoat asking prices and the GetBoat market index.

The short answer

  • Entry scales exactly with the group: the median motor yacht 62-85 ft asks €2,408,700, so four partners each fund €602,175.
  • Five-year net cost — purchase plus running budget minus your share of the resale — is €518,662 per partner against €2,074,646 for a sole owner of the same yacht.
  • Cost per week on board does not fall with the group; capital, running costs and depreciation exposure do. That is the trade the maths actually supports.

The three numbers that decide a share

Every honest co-ownership calculation has three inputs and one output. The inputs: the yacht’s price, the annual running budget (crew, berth, insurance, maintenance, survey and class work — around 10% of price a year for a professionally run 50–110 ft yacht), and what the yacht is worth when the group sells. The output is net cash cost: what leaves your account over the holding period, after the resale comes back.

We take price from our own catalogue: 415 euro-converted asking prices of 50–110 ft yachts listed for sale on 2026-09-20. We take the resale from the GetBoat market index, which tracks 8,474 priced listings and puts value retention at 72% after 5 years.

The ladder, class by class

Read the table across, not down. “Entry at 4 partners” is the capital you commit; “5-yr net per partner” is what the whole exercise costs you once the yacht is sold and the proceeds are split.

The motor yacht 62-85 ft line is the clearest: €2,408,700 of yacht becomes €602,175 of capital and €518,662 of five-year net cost — 75% below the sole-owner figure for the identical yacht.

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.

Where the saving comes from

Three components move together. Capital divides by the number of partners. The running budget — €240,870 in year one for the median motor yacht 62-85 ft, €1,278,812 across five years with 3% annual growth — divides the same way. So does the value the yacht loses: €674,436 over five years on the index curve, or €168,609 each.

What does not change is the cost of a week on board, because your weeks divide by the same number. A share is not a discount on sea time. It is the same sea time you were going to use, paid for without funding the weeks you were not.

How to sanity-check any quote against this

Ask three questions of any co-ownership proposal. What is the underlying yacht’s asking price, and how does it sit against the class median above? What is the annual running budget as a percentage of price, and who sets it? What is assumed for resale value and selling costs at the end?

If a proposal cannot answer all three with numbers, it is not a financial case — it is a brochure. The model here is deliberately conservative: it excludes VAT, financing, personal tax and any programme fee, all of which are specific to the buyer and the yacht.

Decision checklist

  1. 1Asking price of the specific yacht compared with its class median
  2. 2Annual running budget stated in euro, not as a vague percentage
  3. 3Number of partners and the resulting entry figure written down
  4. 4Resale assumption and selling costs stated for the end of the term
  5. 5Weeks a year each owner receives, and how peak weeks are allocated
  6. 6VAT, flag, financing and tax treated separately from this model
Common questions

What buyers ask next

Does co-ownership make a week on board cheaper?

No, and any provider claiming it should be checked. Your weeks divide by the same number as your costs: at four partners the median motor yacht 62-85 ft gives 10 weeks a year for €518,662 over five years — the same cost per week as owning it alone and using 40 weeks. What falls is capital, running cost and depreciation exposure.

Why use asking prices rather than sale prices?

Completed transaction prices are not public in this market. Asking prices are what a buyer actually faces, and across hundreds of listings the median is a stable benchmark. Treat every figure here as the price of entry to a negotiation, not its outcome.

What is excluded from these figures?

VAT, import duties, financing costs, personal tax, and any programme or management fee. They depend on the buyer’s residence, the flag and the structure, and adding an average for them would make the comparison less honest, not more.
