The field

Each number is one boat: its asking price in thousands of pounds, at today's market level, set above the year it was built. Tap a number to see the boat behind it. The price scale is logarithmic: each step up is the same percentage.

10 boats is too few to draw a middle line. We draw one once 20 boats span six build years.

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.

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.

Age

Too few boats to fit an age rate yet.

—we fit one once 20 boats span six build years
Other factors

Too few boats to compare factors yet: we need five on each side of a split.

—engine hours, VAT, where it's listed, engines, fuel and hull, each age for age

Asking prices, not sold. Factors can overlap, so treat these as a guide to what the market asks, not a formula.

05

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.

About the Trojan F36

The boats behind this page were built between 1971 and 1989 and have been listed since Sep 2020, most often in the US 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 10 boats here were listed in the US. Full methodology
