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 6.9% off the asking price.
Too few boats to compare factors yet: we need five on each side of a split.
Asking prices, not sold. Factors can overlap, so treat these as a guide to what the market asks, not a formula.
Time to sell
listed so far: the median of 19 boats seen on two or more dates
have cut their asking price: 8 of 19 boats seen at least 14 days apart
median size of that cut, from the highest earlier ask
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.
Cost to keep
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.

The boats behind this page were built between 2015 and 2024 and have been listed since Nov 2024, most often in the US market. 42% 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 23 boats here were listed in the US. Full methodology
