Grandezza has been one of Finland’s top-quality boat brands for many years. The shipyard offers models ranging from 25 to 37 feet. From 28 feet upwards, the boats become fully-fledged travelling companions. A solid standard specification, well-thought-out layout concepts and the typical Nordic design characterise the model range: bright, spacious and with impressive build quality.
With the new Grandezza 34 Outboard, the shipyard’s second-largest boat is now available in an outboard version for the first time. This is intended to simplify maintenance and servicing and, above all, to enhance the enjoyment of sailing. We can definitely confirm the latter following our test in the Swedish archipelago. There, we had the opportunity to compare both the inboard and outboard versions side by side.
The Grandezza 34 features modern, clean lines and a good dose of Scandinavian understated elegance. The forward-sloping bow not only improves visibility from the helm but also gives the boat a dynamic silhouette. The high railing follows the deck line and provides a secure handhold at all times on the way to the bow. The wide side decks also ensure a safe passage to the bow. A generous sun lounger is fitted at the bow. About two-thirds of the way along the boat’s length, the windscreen – which extends well forward – begins; it rises at a shallow angle, lending the boat a sporty character. The hull itself is deliberately simple. A decorative strip, the hull windows and clean surfaces define its appearance. No extravagant shapes, no fanciful frills. A wraparound rubber rubbing strake protects the hull side during harbour manoeuvres.
Another striking feature is the spacious bathing platform at the stern. High-quality stainless steel details, recessed fittings and the optional teak surfaces underline the shipyard’s commitment to premium quality. The boat is fitted with two 300 PS Mercury outboard engines. These are the only engines currently available. From the swim platform, we step directly into the saloon. This has an exceptionally open layout. There is no fixed rear window or door to close off the space; only a rear canopy provides protection from wind and rain when needed. This creates an airy, spacious feel, but also makes it clear that a powerful heating system on board is essential for use on cold days or in winter. A simple fan heater won’t be enough here. The four-kilowatt heater is on the optional extras list.
The sun lounger at the stern can be extended by folding down the backrest. This creates a lounging area for two. Cup holders have also been provided. On the starboard side, there is a raised seating area with space for up to eight people. The table can be folded out and lowered, creating an additional sleeping space here if required. Opposite is the galley. It offers everything you’d expect on a holiday boat of this size: a sink with hot and cold water, a two-burner hob and a generously sized fridge, which provides ample storage space even for longer cruises. Right next to it is a single seat with good lateral support.
The helm is also seamlessly integrated into the saloon. It makes a favourable impression, both visually and ergonomically. All the switches are easily accessible and feature a classic toggle design. Whilst this may seem somewhat conservative, it proves to be thoroughly practical at sea. Particularly in choppy conditions, toggle switches are often easier to operate than modern push-button switches.
A bow thruster is fitted as standard. The control unit is situated right next to the three-spoke steering wheel bearing the Grandezza logo. Behind it sits a generously sized 16-inch chartplotter, which clearly displays all relevant navigation data. A classic magnetic compass has also found its place in the cockpit – a feature we’re always pleased to see.
The large sliding roof above the seats can be opened. This provides pleasant ventilation whilst driving. Thanks to the slender roof pillars, you can enjoy an almost unrestricted all-round view from the driver’s seat.
Below deck, the Grandezza is surprisingly spacious for a 34-foot boat. In addition to the owner’s cabin in the bow, there is a mid-cabin and a separate bathroom. Both cabins offer ample storage space for longer voyages. The berths in the bow measure 1.46 by 2.00 metres. In the mid-cabin, the width is around ten centimetres narrower, whilst the length remains the same. There is little cause for complaint regarding headroom either. The mid-cabin offers 1.87 metres of headroom, whilst the forward cabin and the bathroom each offer 1.85 metres. In the saloon, there is even a comfortable 1.97 metres of headroom. Only people significantly taller than 1.90 metres will need to duck their heads slightly here and there.
The mattresses are comfortable and are also suitable for longer stays on board. The cupboards are large enough to accommodate luggage for a holiday cruise. Fresh air enters the interior through several hatches.
The light-coloured interior wood in a modern oak shade creates a particularly welcoming atmosphere. Those who prefer a more classic look can opt for a mahogany-coloured finish instead. In fact, the Grandezza offers extensive customisation options. Carpets are available in two colours, whilst upholstery, side panelling and bed surrounds come in three different variants. Headboards, blackout blinds and numerous other details can also be customised. This personalisation concept is consistently applied throughout the entire boat. Virtually any colour combination can be tailored to suit your own preferences.
But however beautiful a boat may look in the harbour, it was built to be sailed. That’s why the Grandezza also had to prove itself on our test course. And let’s get one thing straight from the outset: compared with the inboard version, it does one thing very differently.
We leave the harbour at Tanum Strand and head out into the Swedish archipelago. Why Sweden, when the shipyard is actually based in Finland? The answer given by those in charge is simple: there is no comparable location for sea trials in Finland, which is why the international sea trials have been taking place in the neighbouring country for years.
At idle, the Grandezza glides smoothly and without any jarring movements out of the sheltered harbour basin. Once out at sea, we increase the revs slightly and chug along at around 6 knots at approximately 1,250 revolutions per minute, cutting through the light swell. The wave height is around 30 centimetres. As speed increases, the boat transitions smoothly into planing. At 3,500 revolutions per minute, the log is already showing around 17 knots. The first turns and evasive manoeuvres immediately reveal the differences compared to the inboard version. The Grandezza feels significantly more agile and lively. Although the overall weight remains almost identical, the outboard engines deliver around 100 PS more than the most powerful inboard variant. In addition, the centre of gravity shifts slightly further aft. This gives the boat noticeably more dynamism.

* This is the most fuel-efficient range during a steady cruise. Measured during our test with five people on board, light swell and a 3-knot wind. 95 per cent petrol in the tank, 12 per cent water.
As the engine speed continues to rise, the Grandezza quickly reaches the cruising speed of 27 knots specified by the shipyard. The fuel-efficient range we measured is 31.5 knots, 4,500 rpm and a fuel consumption of 110 litres per hour. The Grandezza completes the subsequent test run with confidence and a sporty flair. At times, it feels more like a large sports boat than a classic family cruiser. This is precisely where its special appeal lies: plenty of comfort and space for the family, combined with handling that offers far more enjoyment than one might expect at first glance.
Back in the harbour, the joystick system makes mooring considerably easier. A stern thruster is also available as an option. However, we do not consider this essential for the outboard version. Modern joystick controls already allow for precise turns in confined spaces and controlled sideways movements without the need for additional assistance.

The boat is built from glass-fibre-reinforced plastic. A Divinycell foam core is used for the sandwich construction. Polyester resin is used, which is typical for this class of boat.
The bow thruster is fitted as standard on the Grandezza 34. A Side Power SE40/125S is installed, powered by a separate 95 Ah 12-volt battery. The battery is fitted in the bow.
Many features that would incur an extra charge at other shipyards are already included as standard on the 34. It is particularly striking that no corners have been cut when it comes to the technical specifications. A 16-inch plotter, joystick, autopilot, electric steering gear and trim tabs are all standard.
There is also a fire extinguisher. That is by no means the norm these days.
The Bavaria SR33 places greater emphasis on lifestyle. Lounge areas, modern design and a versatile deck layout make it an attractive all-rounder boat. It is now called the Bavaria SR35. Price: €311,780
Like the Grandezza, this French yacht is aimed at cruising and family crews. With its generous space and several cabins, it is an interesting alternative. Price: €242,760
