Grandezza 30

Name: Grandezza 30
Brand: Grandezza

In production 2023–present

The Grandezza 30 is the current 9.4-metre model from Oy Finn-Marin Ltd of Kokkola, launched at the Helsinki Vene 23 Bat boat show in 2023 and still in production. It is sold in two inboard forms on a common hull — the 30 CA with a sliding aft door closing the saloon and the 30 OC with an open cockpit and canopy — and, since the Cannes Yachting Festival in September 2025, as the twin-outboard 30 Outboard on a related but distinct hull. The inboard boats take a single Volvo Penta D4-320 or D6-380 on a DPI leg, or a Yanmar 8LV-370 Z-drive package. Accommodation is two cabins and four berths with a separate shower compartment, and the boat is certified for ten people in CE category C. There is no earlier Grandezza 30: the number was unused until 2023.

The 30 replaced nothing directly — it is a new size for Grandezza, slotting between the 28 DC/OC and the 34 OC, and it introduced the yard's current design language of a low, glazed superstructure, large fixed hull windows and a full-width sliding sunroof over the helm. The saloon and cockpit are on one level with sofas fore and aft of a powered-pedestal table, and the difference between the two inboard versions is at the back: the 30 CA closes the saloon with a sliding aft door and wall, while the 30 OC leaves the cockpit open and covers it with a canopy. Below decks are two proper cabins — a forward cabin with scissors berths that make up either as a double or as two singles, and a mid cabin with a fixed double — plus a bathroom with a sea-water toilet, electric flush and a shower.

The hull is GRP built by vacuum infusion, which the yard cites for stiffness and low weight, and the boat comes out at 4138 kg dry in inboard form. Standard equipment is comprehensive: 12-inch Garmin or Simrad plotter, Side-Power bow thruster with joystick switch, hydraulic steering, trim tabs, Wallas ceramic hob, 70-litre fridge, 22-litre hot water and a 140-litre holding tank. The option list runs to Seakeeper RIDE, air conditioning, solar panels on the roof, grey-water plumbing and a choice of Garmin or Simrad electronics suites.

Inboard power is a single sterndrive: Volvo Penta D4-320 or D6-380 on the DPI leg, or a Yanmar 8LV-370 with its ZT370 Z-drive. Maximum installed power on the inboard boat is therefore 380 hp. The 30 Outboard, unveiled as a world premiere at Cannes in September 2025, is a different proposition and a different set of numbers — 9.35 m LOA, 4505 kg, a 760-litre fuel tank against the inboard boat's 420, and twin outboards from 2 x Yamaha F200 up to 2 x Yamaha F300 or 2 x Mercury V300, so up to 600 hp. Those figures are described here rather than merged into the specification block, because they belong to a different variant.

Two caveats. The specification block above is the inboard 30 OC/CA only; a listing for a 30 Outboard will not match it. And the draft basis differs between the yard's two sheets: the inboard sheet gives "0,70/1,20 M", of which 1.20 m is the leg-down figure used here, while the outboard sheet gives only "DRAFT (HULL) 0,56 M", which is not a comparable measurement.
