The June 2026 issue of Moteur Boat Magazine, one of France’s leading boating publications, renowned for its in-depth boat tests and expert sea trials, shines a spotlight on Grandezza’s latest outboard-powered range, putting the Grandezza 30 Outboard, 34 Outboard, and 37 Outboard through comprehensive sea trials.

Built in Finland by Finnmaster Boats, these three models showcase the brand’s commitment to premium Finnish craftsmanship, combining elegant styling, practical cruising layouts, and modern Mercury outboard performance. While new to the French market, the magazine concludes that Grandezza’s latest generation of weekend cruisers is fully capable of competing with established names in the segment.

The review highlights how the move to twin Mercury outboard engines has transformed the Grandezza range, delivering stronger acceleration, higher top speeds, and outstanding handling while retaining the comfort expected from family cabin cruisers. Across all three models, the magazine praises the refined Nordic finish, tested hulls, advanced technological features such as joystick docking, electric steering, Seakeeper stabilization options, and thoughtfully designed interiors with two comfortable cabins.

Performance was another standout during testing. The Grandezza 30 Outboard reached over 41 knots with twin Mercury V8 250 hp engines, while the Grandezza 34 Outboard achieved an impressive 46 knots with twin Mercury 300 hp V8s. At the top of the range, the Grandezza 37 Outboard combined luxury cruising accommodation with exhilarating performance, reaching more than 43 knots powered by twin Mercury 400 hp V10 engines. Moteur Boat Magazine concludes that Grandezza has successfully blended premium quality, innovative technology, and dynamic performance into a range of Scandinavian weekenders that deserve far greater recognition.
