Cannes, France · world premiere at the Cannes Yachting Festival.

A 10.15-metre day cruiser on twin 300hp outboards, with two cabins below and seating for eight.

Speed by day, space by evening

Grandezza pitches the 34 Outboard at sun-drenched days and adrenaline-fuelled adventures. The yard says the outboards offer thrill and speed during the day, while generous indoor and outdoor spaces are there to relax in as the sun goes down.

A U-shaped cockpit and a worktop that extends

The large cockpit is meant for entertaining and sunbathing, with a U-shaped lounge seating everyone aboard. Large sunbeds sit aft and at the bow. The galley is well equipped, including a worktop extension and generous storage.

Grandezza says the 34 Outboard was selected as a finalist in the Best for Family category of the Best of Boats Awards 2026. The finalists were announced at the Cannes Yachting Festival on 9 September 2026.
