What moves the price
Each factor compares boats of the same age, so a newer boat's premium isn't counted twice. Five boats or more on each side, or we say so.
Each year of age takes about 7.2% off the asking price.
Too few boats to compare factors yet: we need five on each side of a split.

Time to sell
listed so far: the median of 13 boats seen on two or more dates
have cut their asking price: 3 of 13 boats seen at least 14 days apart
median size of a cut · withheld: fewer than five cuts to measure
These are asking prices, and asking is not selling. Days listed so far is not time to sell: a boat still listed has not sold, and we do not yet record when a listing ends. We have not measured how far sale prices land below asking; the methodology says what we can and cannot measure.

A year on a South Coast marina berth, insured at the Gauge Value, in pounds. An estimate from published rates, not a quote.
Fuel is not included: no cited source gives the engine hours a typical owner runs in a year.

About the Galeon 640 Fly
The boats behind this page were built between 2009 and 2025 and have been listed since Mar 2021, most often in the US market. 23% of the boats seen at least 14 days apart have cut their asking price.
How we measure: we read public listings from brokers and marketplaces, count a boat once when it appears on several sites, store its asking price each time it changes, and restate older asking prices at today's market level. We never republish a listing, a photograph or a seller. Every figure is recomputed nightly and dated; below five boats we publish nothing. The 21 boats here were listed in Europe and the US.
