Highfield Boats has launched the 9.2-metre ADV9 adventure crossover at boot Düsseldorf 2026, quoting a top speed of 50 knots and range up to 250 nautical miles. The underlying announcement was published by Highfield Boats on 17 January 2026, giving the development a clear primary-source date and provenance.
For buyers comparing smaller leisure craft, the important point is that the model range itself has changed. In boats below 12 metres, differences in deck layout, propulsion, protection and overnight capability can materially change how a boat fits its intended use. LBG records new-model announcements against a dated primary source so later specification or model-year changes can be separated from the original launch.
For Leisure Boat Guide, the relevance is the confirmed change described by Highfield Boats, not the promotional language around it. The source is retained with this article so readers can review the original material and check any technical, regional or commercial details that sit beyond this news brief.
LBG's scope remains leisure boats below 12 metres. Model stories in this batch are confined to craft inside that limit, while equipment and company stories are included only where they directly concern the recreational small-boat market; broader products mentioned by a source are not being added to LBG by implication.
This article preserves the Highfield Boats source as the verification trail for the announcement. If specifications, availability, partnerships or product details change later, LBG can report those as separate updates rather than silently rewriting the historical news record.
