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 Aicon 64 Fly

The boats behind this page were built between 2005 and 2010 and have been listed since Sep 2020, most often in the European market. 7.7% 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 21 boats here were listed in Europe and the US.
