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.

15 boats is too few to draw a middle line. We draw one once 20 boats span six build years. 1 boat off the scale is marked ↑ or ↓ at the edge.

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

About the Bertram 60 Convertible

The boats behind this page were built between 1990 and 2012 and have been listed since Feb 2021, most often in the US market. 0% 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 15 boats here were listed in the US. Full methodology
