About the Sealine SC35

The boats behind this page were built between 2008 and 2023 and have been listed since Oct 2020, most often in the UK market. 30% 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 19 boats here were listed in the UK and Europe.
