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. The orange line is the model's middle price for its age; the shaded band holds the middle half. Tap a number to see the boat behind it. The price scale is logarithmic: each step up is the same percentage.

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.

About the Sea Ray 240 Sundancer

The boats behind this page were built between 1979 and 2011 and have been listed since Sep 2020, most often in the US market. 28% 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 54 boats here were listed in the UK and the US.
