There is no universal answer, only a right answer for how you will use the boat and how long you will keep it. Below is the trade-off as brokers on the Côte d'Azur actually see it, with the numbers and timings that matter most.
Most production yachts lose the steepest share of their value in the first two to three years. If you plan to keep the yacht for a decade, that curve flattens and matters far less. If you expect to change boats every three years, buying a well-kept two- to four-year-old yacht lets the first owner absorb the drop while you still get modern systems and remaining warranty.
A new build lets you specify layout, engines, finishes and electronics exactly, but popular yards on the Riviera quote long lead times and prices can be indexed. A used yacht is available now, which matters if you want the boat for this season. If your requirement is unusual — shallow draft, specific cabin count, particular tender garage — new build may be the only way to get it.
New yachts carry hull and engine warranties and yard support for commissioning faults, which is real value in the first two seasons. Used yachts trade warranty for a known service history: a boat with complete records, recent engine servicing and a recent antifouling is often the lower-risk purchase, despite having no warranty.
Budget realistically for what a used boat will need in the first year: sails or canvas, tender and outboard, electronics refresh, upholstery, batteries, and any survey items. On a ten-year-old yacht it is common for that first-year spend to run to a meaningful share of the purchase price. Get the survey done before you finalise the price, and use it.
Berth, insurance, crew if any, servicing, antifouling, winter storage and fuel do not change much between new and used of the same size. Length overall drives running cost more than age. Many buyers are better served by a slightly smaller, newer, well-equipped boat than by the largest hull their purchase budget allows.
Strong builders, popular layouts, low engine hours, complete documentation and EU VAT-paid status all support resale. Unusual custom colours, one-off interiors and boats with gaps in the service record take longer to sell. If resale matters to you, buy what the next buyer will also want.
