The field

Median from five boats; middle half from ten. Below that we print nothing rather than a guess. Linked years have their own page with that year's boats. The spread is drawn on the field's logarithmic scale, in pounds.

Too few boats to fit a depreciation rate yet. We fit one once 20 boats span six build years.
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.
Too few boats to fit an age rate yet.
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
days listed so far · withheld: fewer than five boats seen on two or more dates
share that have cut their asking price · withheld: fewer than five 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.
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.

About the Sealine 305 Statesman
The boats behind this page were built between 1984 and 1992 and have been listed since Apr 2021, most often in the UK market.
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 6 boats here were listed in the UK and Europe.
