Stingher 34 GT – 2 x 300hp Verado 4.6L V8
The brand new Stingher 34 GT, now the flagship of the GT series, can be considered the starting point in the evolution of a new range of luxury Rib-cruisers by Italboats. This model combines bold and aggressive design with cutting-edge technology, elevating the sea experience to high levels.
The design of the 34 GT is an excellent example of elegance, ergonomics, and functionality. Its sharp aerodynamic lines reflect aesthetic care while seamlessly integrating with hydrodynamic performance. The raised bow and the particularly sharp design interventions in the hull attract attention and optimize cruising levels, ensuring high performance even in challenging sea conditions.
By adopting a gradual elevation of the air chambers from the cockpit area forward, the 34 GT ensures a spacious cabin, providing the utmost comfort for onboard living. The hull is characterized by a steep vertical bow and a pronounced entry angle, with a deep V extending throughout its length. Three spray rails start from the stem and end at the large step formed at the height of the console. From there, only the two upper spray rails continue toward the stern, with the outermost reaching the transom while the second stops one meter before it.
The chine follows an arched course from the bow to the step, reaching a maximum width of 36 cm midway and measuring 11 cm at the stern. Just behind the step, the edge of the dihedral gives way to a gradually increasing pad that reaches a maximum width of 20 cm at the transom area. From the transom and extending 5 cm higher, the integrated bracket starts and stretches 95 cm in length, playing a crucial role in the vessel’s navigation at both low and high speeds.
On Deck
Stingher 34 GT has been designed to offer ultimate comfort, setting the benchmark for those seeking an elevated sea-living experience. Its deck layout merges ergonomics with functionality, paying great attention to detail to ensure excellent freedom of movement for all passengers.
At the bow, a large sunbed measuring 2.70 meters in length and 1.95 meters in width at the feet area provides the perfect space to enjoy the sun and sea in absolute relaxation. Additionally, 15 cm above the front cushions, the console features a very comfortable double seat, ideal for relaxation even during travel as long as weather conditions permit.
Beneath the front cushions of the bow sundeck, two large independent lockers are housed. The forward one provides access to the windlass, while the second, boasting a massive volume and a height of 1.18 meters, can accommodate all the vessel’s equipment and multiple passengers’ luggage.
The width of the free deck between the helm station and the helm seats reaches an impressive 1.95 meters, ensuring ample freedom of movement for passengers. The double helm seat is positioned on the front surface of the high polyester structure, which constitutes the vessel’s external kitchen.
Lifting the kitchen lid reveals a gas stove and a sink, while underneath lies the stainless-steel refrigerator and a large storage space. Wide passages, 44 cm in width, on both sides ensure smooth fore-and-aft movement.
One of the Stingher 34 GT’s most striking features is its exceptionally large and beautifully designed console, measuring 1.69 meters in width and perfectly complementing the vessel’s overall aesthetics. Centrally located, it allows for 20 cm-wide walkways on either side, which are slightly lower than the upper surface of the air chambers.
The view towards the bow and horizon is stunning whether driving in a seated or standing position. The instrument panel accommodates two large navigation screens, angled for easy monitoring from any driving position. Below them, a row of high-quality switches enables control of all the vessel’s electrical equipment.
Special mention must be made of the spacious and bright cabin interior, offering a warm and comfortable environment, ideal for extended getaways to secluded and idyllic coves. Opening the sliding door reveals three steps leading inside, where a large bed measuring 1.93 meters in length and 2.22 meters in width is located, with ample storage space beneath the cushions.
The highest cabin point measures 1.81 meters, while the lowest, at the headboard area, is 57 cm high. The separate bathroom space is relatively compact, with dimensions of 0.83m x 0.85m x 1.81m, equipped with a toilet, sink, and a highly practical storage area.
At the stern, the lounge area is impressively spacious, with a centrally positioned table measuring 1.22m x 0.85m. This table can be lowered to the height of the sofas, transforming the space into a generous sunbed for relaxation and sunbathing.
Two long, narrow hatches on either side provide access to the interior of the side gunwales, measuring 0.27m x 2.15m. These serve as particularly useful storage spaces for long equipment such as flippers, paddles, and spearguns.
Additionally, two small doors at the backrest of the stern sofa lead to the expansive swim platform, which measures 2.97 meters in width and 0.93 meters in length. This ensures ample free surface area for all sea-related activities.
On either side of the platform, discreet hatches conceal cleverly designed ladders, while at the center, two compartments provide access to another large storage area corresponding to the interior of the boat’s bracket.
At Sea
Our test boat was fitted with two V8 4.6L Verado 300 hp engines, with a reduction ratio of 1.85:1, spinning 21-inch pitch 4-blade Revolution stainless steel propellers.
With 150 liters of fuel and a two-person crew, we navigated into the waters of the Thermaicos Gulf, maintaining a steady speed of just 26 knots at 4000 rpm for an extended period.
A light swell reaching one meter offshore immediately revealed the boat’s offshore character. It traveled smoothly, staying well above the waterline, with its large air chambers limiting the inclinations during sharp maneuvers.
Although weather conditions did not allow us to fully assess the quality of the 34 GT’s ride, it was evident that damping levels were excellent, while the throttle response was impressive given the vessel’s volume and engine configuration. However, the selected propellers were clearly unsuitable.
Nevertheless, the Revolution propellers kept us on plane at just 2000 rpm at a speed of 11 knots, achieved planning in 4 seconds, and accelerated to 30 and 40 knots in 7 and 11 seconds, respectively.
At 3000 rpm, we cruised at 17 knots with a fuel consumption of 2.3 liters per nautical mile, while at 3500 rpm, we reached 22 knots, maintaining the same fuel consumption. These speeds represented the most economical cruising options, maximizing range.
At 4000 rpm, we recorded 26 knots burning 2.6 liters per mile, and at 4500 rpm, we gained additional 6 knots with consumption increasing to 2.9 liters per mile.
At WOT, we achieved a top speed of 48.8 knots, with the engines exceeding their maximum rpm limit.
You can see our measurements in the table below:
Taking a good look at the measurement chart, we noticed high slip values across the whole rpm range, indicating the unsuitability of the propellers used
Switching to ECO Enertia propellers with the same pitch would significantly reduce slip, resulting in increased cruising speeds at low and mid rpm ranges and consequently reducing fuel consumption. Additionally, throttle response and maneuverability in rough conditions would be further enhanced.
