The crossover that crosses oceans
The GranSport 45 sits in the middle of the fast displacement line, above the 34 and 38 and below the 50 and 54. First delivered around 2021, it was one of the boats that defined the modern GranSport idea. At 45.3 metres and built in aluminium it steps up from the composite baby boats into genuine long range territory. Alberto Mancini shaped the exterior with the Overmarine office handling the interior.
The GranSport family exists to blend the reach of a displacement yacht with the style and turn of speed of a Mangusta. The 45 is where that blend really hits its stride. It can cross oceans at an easy pace and still lift its skirts for a fast run between anchorages. For owners who want to actually go places, this is a serious tool.
Aluminium hull, sporting profile
The 45 carries the low, muscular GranSport look on an aluminium hull that keeps weight in check at around 444 GT. A plumb bow and long clean superstructure give it real presence, while wide glazing floods the interior with light. Broad side decks and a generous aft cockpit make moving around the boat easy underway. A large sun deck up top gives the owner an outdoor helm and space to relax with a view.
The exterior detailing balances the sporting stance with the practicality a long range boat needs. Tender and toy stowage, good tankage and proper deck space for ocean passages are all worked into the design. The aluminium build also helps the boat shrug off the miles that a true crossover is meant to cover. Shaded aft areas and a broad sun deck give guests cool space to gather when the sun climbs high. Everything on deck points to a yacht built to be used hard and often.

Five cabins for the long haul
Below deck the 45 sleeps up to 12 guests in five cabins, with a full beam owner's suite taking the widest part of the hull. VIP and guest cabins are arranged for privacy, and hull windows keep the lower deck bright. The main deck saloon flows aft to the cockpit for open air living when the weather allows. Crew of seven live in four cabins, enough to run the boat properly on long trips.
Interiors are a semi custom commission through Alberto Mancini and the Overmarine design office. Owners set the materials and layout to suit long cruising, from warm timber schemes to lighter modern ones. Storage and comfort are worked to a standard that matters when a boat is lived aboard for weeks. The volume of a 45 metre aluminium hull gives the designers plenty to work with.
Three engines, shafts and a booster jet
The 45 uses a distinctive three engine setup. Two MTU 16V 2000 M96L engines drive conventional shaft lines with fixed pitch propellers, while a third central engine feeds a Kamewa booster waterjet. At displacement speeds the shafts do the work efficiently, stretching the range to around 4,200 nautical miles. When the owner wants pace, the central jet joins in and lifts top speed to about 26 knots.
That hybrid drive is the clever core of the boat. It means the 45 does not have to choose between long legs and a fast top end because it can do both. Fixed pitch shafts keep the cruising numbers economical, and the booster jet adds a real kick for shorter hops. The central jet also draws less water than a third propeller would, which suits the boat's shallow anchorage work. It is an unusual arrangement and it is exactly what makes the GranSport 45 such a flexible cruiser.
The owner it suits
The 45 suits the owner who genuinely wants to travel, not just move between the same few harbours. Its 4,000 mile range opens up long passages and remote cruising grounds far from home. When the mood changes, the booster jet delivers a fast run that a pure displacement boat could never match. Families settle easily into the five cabin layout for extended trips.
It also fits an owner moving up from a smaller crossover who now wants ocean ability. The aluminium build and proper crew accommodation make weeks aboard comfortable. Running the boat needs a modest professional crew, well within reach of a private owner. For a buyer who wants one yacht that can both cross an ocean and sprint between islands, the 45 is hard to beat.
Who it is for: The owner who wants one yacht that can cross an ocean at an easy pace and still sprint between islands at 26 knots.
