Only 5 boats have been listed since Apr 2021, a median of £89,000€103,500$119,000 in today's prices. That is enough for a first reading but not a firm guide, so treat it as provisional.

01

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.

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

Gauge Estimate · withheld

Only 2 comparable boats within 3 years of 2020. That is too few to estimate from.

The model's overall median is £89,000€103,500$119,000 across 5 boats. We'll publish an estimate for 2020 once five comparable boats have been listed.

By year built

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.

04

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 Chris-Craft 28 Sportsman

The boats behind this page were built between 1964 and 2020 and have been listed since Apr 2021, 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 5 boats here were listed in Europe and the US.
