On Deck
The GranSport 45 is an interesting yacht because it doesn't force you to choose between a high-performance GT and a full-size superyacht. At 45 metres, you'd expect generous guest accommodation, proper crew facilities and plenty of places to spend time outside. You get all of that here. What perhaps comes as more of a surprise is that this aluminium yacht is also capable of 26 knots. It gives the whole boat a different character. Long, low and unmistakably sporty, she looks ready to move even when sitting quietly alongside the dock.
One thing that quickly becomes obvious is that there isn't a single headline deck space. Every time you think you've found it, another one appears. The cockpit opens naturally from the main saloon, the upper deck becomes an outdoor dining and entertaining area, the bow offers another destination entirely, while the beach club transforms the stern into a waterside retreat. Rather than repeating the same arrangement from deck to deck, each area has its own purpose and personality.
The upper aft deck will probably become the social heart of the yacht. A large dining table sits beneath the shelter of the deck above, with a proper bar close at hand, generous seating aft and a hot tub surrounded by sunpads. It's very easy to picture the day unfolding here. Breakfast outside, lunch after a swim, drinks as the sun starts to drop and dinner without anyone feeling the need to move very far. Despite everything that's packed into the space, it never feels crowded.
Move forward and the mood changes completely. The bow feels quieter and more relaxed, with broad sunpads wrapped around a compact pool. Then there's a lovely little detail that could easily go unnoticed. Beneath the water are opaque skylights that feed natural light into the owner's en suite below. As the water moves, soft ripples play across the ceiling of the bathroom. It's a clever touch, and exactly the sort of detail that tends to stay in the memory long after you've left the boat.
One obvious question comes to mind with so much of the stern dedicated to the beach club. Where does the tender go? Mangusta's answer is rather clever. Instead of sacrificing guest space aft, the tender garage sits beneath the foredeck with room for a substantial Williams tender and personal watercraft, all launched and recovered by crane. It keeps the working side of the yacht out of sight without compromising practicality.
The beach club is every bit as impressive as expected. The transom lowers to create easy access to the sea, while fold-down balconies on both sides open the whole area to the water. Suddenly it feels far larger than its footprint suggests, with light and fresh air arriving from three sides. A large daybed looks straight out across the stern, there's a sauna tucked neatly into the centre of the space, and a nearby day head means there's no need to head back into the accommodation after every swim. It's somewhere guests could happily spend an entire afternoon.
What works particularly well is that the outside spaces never compete with one another. Want somewhere lively? The upper deck has that covered. Looking for a quiet coffee in the morning or somewhere to stretch out with a book? The bow feels a world away. Fancy spending the day in and out of the water? The beach club becomes the obvious choice. Plenty of yachts this size offer generous deck space. The GranSport 45 simply gives each area its own identity, and that makes the yacht feel every bit as dynamic at anchor as it does underway.
Interior Accommodation
Floor-to-ceiling windows run right down both sides and they completely change the feel of the room. Alongside the dock they already make the space feel huge, but out at anchor the view would become part of the interior. It's absolutely beautiful and exactly the sort of space where you could happily sit for hours without ever switching the television on.
Talking of televisions, one nice detail is that you don't actually see one. The AV equipment disappears completely behind the mirrored panel when it's switched off, so instead of a big black screen dominating the saloon, all your attention stays on the view outside. There are lots of little touches like that throughout the yacht. Nothing shouts at you, but the more time you spend looking around, the more you notice.
One thing that is quite interesting is that there isn't a dining table in here. At first that feels a little unusual on a 45-metre yacht, but it quickly starts to make sense because the formal dining area sits on the upper deck instead. That leaves the whole of the main saloon to do one job, and it does it really well. It's somewhere to sit, relax, enjoy the view and spend time together without trying to be everything at once.
The finishes follow much the same thinking. Lovely dark timber runs throughout the interior, subtle lighting is worked into the shelving and cabinetry, and there are very few hard edges anywhere you look. Even the day head is tucked discreetly away behind a sliding door, so unless somebody points it out, you'd probably walk straight past it. It's all very clean, very contemporary and, despite the scale of the yacht, never feels overdone.
Keep looking and more clever details begin to appear. Storage disappears behind flush panels with just a gentle touch, sliding doors vanish neatly into the structure when they're open, and technology stays largely hidden until you actually need it. It gives the whole interior a calm feel because you're never looking at equipment or clutter. Instead, your eye naturally drifts towards the windows, the lighting or the craftsmanship in the joinery.
For a yacht that's capable of 26 knots, the interior has a surprisingly relaxed feel to it. There isn't anything loud or flashy about it. Instead, it's all about space, light and some really lovely detailing. It's a very easy interior to spend time in, and that's perhaps the biggest compliment that can be paid to it.
Owner's Cabin
The owner's suite occupies the forward section of the main deck and, before anything else, it has a huge amount of space. The walk-in wardrobe is enormous. In fact, it's about the size of a cabin on many smaller yachts. There is hanging space everywhere, plenty of room to move around, and even a full-height mirror. It's one of those spaces that immediately gives you a feel for the scale of the yacht.
From there the cabin opens out, and it's every bit as impressive. Floor-to-ceiling glazing fills the room with natural light, while the drop-down balcony on the starboard side completely changes the feel of the space. It's a brilliant feature. Sit out there with a coffee first thing in the morning, or a drink later in the day, and you've got an uninterrupted view right down the length of your own yacht. It's the sort of place that's very easy to imagine using because it feels connected to the sea rather than simply looking out at it.
There are some lovely details throughout the cabin as well. The television disappears completely behind a mirrored panel when it's not in use, keeping the room clean and uncluttered, while subtle lighting has been worked into the joinery without ever drawing attention to itself. Nothing feels overdone. The space is big, calm and very easy to spend time in.
The en suite is every bit as generous, and there's another interesting detail waiting inside. Look up and you'll notice soft reflections moving across the ceiling. That's the light coming down through the skylights beneath the foredeck pool. You can't see through them, but they allow the movement of the water above to filter into the room below. It's a very nice touch and something that's quite different from the usual approach.
Everything else is on the same scale. The shower is huge, with large windows bringing in plenty of natural light, and sliding doors allow the bathroom to remain completely open to the cabin or closed off for privacy. Even on the way out there are more little discoveries, with additional wardrobes, generous storage and neatly integrated lighting tucked into the shelving. Every time it feels as though you've seen everything, another detail appears.
It's very easy to focus on the size of this suite because it really is enormous, but that's not actually what stays in the memory. It's the balcony, the rippling light from the pool above, the hidden television and that astonishing wardrobe.
Guest Accommodation
Guest accommodation sits on the lower deck and, as configured, the GranSport 45 offers four guest cabins. Two full-beam VIP doubles occupy the aft section, while the forward guest area has been customised around family cruising. Here, one cabin has been arranged with four berths for children, alongside a separate nanny's cabin. It's a very specific layout for the current owner, but Mangusta has already developed alternative plans that allow this area to return to a more conventional arrangement with two independent guest cabins, each with its own en suite.
The two VIP cabins are particularly impressive. On many yachts they'd comfortably pass as owner's cabins, with large double beds, generous wardrobes and en suites that feel every bit as substantial as you'd expect on a yacht of this size. The cabins mirror one another on either side of the yacht, creating a nice balance, and there's no sense that either has been treated as the secondary option.
Storage is another thing that quickly stands out. Flush wardrobe doors open with just a gentle touch, revealing plenty of hanging space without interrupting the clean lines of the cabins. It's a small detail, but one that fits nicely with the rest of the yacht, where cupboards, televisions and technical equipment all seem happy to stay out of sight until they're needed.
The en suites continue that feeling of space. Large rainfall showers, wide vanity units and more subtle lighting give them the same calm atmosphere found elsewhere on board. One particularly nice touch is the concealed drain within the basin, another example of Mangusta paying attention to details that many people might never consciously notice but which all help create a very clean finish.
Forward, the children's cabin reflects the way this particular owner uses the yacht. Four berths allow brothers and sisters to share the space, while safety rails on the upper bunks make it suitable for younger guests. Next door, the nanny's cabin allows family accommodation to stay together, creating what is effectively a dedicated children's area. It's an interesting arrangement, and one that makes a great deal of sense for the current owners.
Of course, not every buyer will have the same requirements, and that's where the flexibility becomes important. Rather than creating a one-off layout that can never be altered, Mangusta engineered the space so it can be converted back into a more traditional guest arrangement without major difficulty.
Crew Accommodation
Crew accommodation is arranged for seven across four cabins, with a private captain's cabin and three twin crew cabins, all with en suites. The layout keeps the working side of the yacht together, while remaining well separated from the guest accommodation.
The crew area centres on a well-equipped galley with extensive refrigeration, supported by a pantry that links directly to the guest spaces above. Access to the side deck allows crew to move between the galley, cockpit and exterior decks without disturbing guests, while a dedicated crew mess and separate laundry complete the lower deck.
Performance & Engine Room
Up on deck she looks every inch the sporty superyacht, and in the engine room, you quickly discover how Mangusta has pulled it off.
Looking at the scale of it all, it's absolutely monstrous. Three MTU 16V2000 M96L V16 engines fill the space, each producing 2,600hp for a combined output of 7,800hp. Just standing down here gives you a real sense of what it takes to push a 45-metre aluminium superyacht to 26 knots.
Rather than fitting three conventional shaft drives, Mangusta uses two shaft-driven engines outboard and a central Rolls-Royce Kamewa waterjet. The obvious assumption is that the waterjet only comes into play when maximum speed is needed. In fact, the opposite is true. Extensive testing showed the yacht is actually more efficient with all three propulsion systems working together, creating a cleaner hydrodynamic flow than dragging an inactive waterjet through the water. It's a clever piece of engineering and one that sets the GranSport 45 apart from more conventional yachts of this size.
Open the throttles and she'll reach 26 knots, which is frankly astonishing for a yacht of these proportions. Ease back to around 20 knots and she'll settle into an effortless fast cruise. Pull the speed back further to an economical 11 knots and the range stretches to around 4,000 nautical miles, giving the GranSport 45 genuine long-distance capability to match her performance credentials.
Splitting the power between two shafts and a central waterjet allows Mangusta to keep the draft down to just 2.2m (7ft 3in), remarkably shallow for a 45-metre yacht. That opens up cruising grounds that might be less comfortable for a more conventional superyacht of similar length.
It's not all about outright performance either. For quiet harbour manoeuvres or late-night arrivals, the yacht can run on the central waterjet alone at around 8 knots, reducing noise while retaining excellent control. It's another example of the thought that's gone into the engineering.
Ownership Considerations
If the priority is crossing oceans at 12 knots with the engines barely ticking over, there are plenty of displacement yachts that will do that very well. The GranSport 45 is, instead, a yacht for owners who enjoy getting somewhere quickly, whether that's moving between islands in the Mediterranean or making the most of a weather window before settling into a favourite anchorage.
That performance comes from some very clever engineering, but it also means buying with your eyes open. The triple-engine installation, twin shaft drives and central Rolls-Royce Kamewa waterjet are unlike the propulsion systems found on most yachts of this size. It's a fascinating setup, but one that rewards owners with an experienced captain and chief engineer who understand both high-speed aluminium yachts and waterjet propulsion.
Service history is particularly important. Three 2,600hp MTUs represent a significant investment, so it's worth looking beyond routine servicing and understanding how the yacht has actually been operated. Engine ECU data can reveal how much time has been spent above 80% load, while the waterjet deserves its own specialist inspection to check for cavitation damage or impeller wear, particularly if the yacht has spent long periods cruising in shallow, sandy waters.
The all-aluminium hull and superstructure are fundamental to the GranSport 45's performance, but they also deserve careful attention during a pre-purchase survey. Ultrasonic hull thickness testing around the shaft brackets and waterjet tunnel, together with a close look at corrosion protection, insulation systems and anode replacement records, can reveal a great deal about how well the yacht has been maintained.
One other area worth spending time on is the beach club. The folding terraces, hydraulic transom and opening platforms are beautifully engineered, but they're also some of the hardest-working systems on board. Rather than simply cycling them alongside the dock, it's worth operating them in open water during a sea trial to make sure everything remains properly aligned under load.
None of that should put anyone off. Quite the opposite, in fact. The GranSport 45 rewards owners who understand exactly what she is. For a yacht like this, a good buyer's broker with access to YachtBuyerPRO can be invaluable. As well as negotiating the deal, they can help uncover upcoming maintenance costs, review survey history and coordinate the specialist inspections a yacht of this complexity deserves.

Rivals to Consider
If you're looking at a GranSport 45, there's a good chance the Sanlorenzo Alloy is already on your shortlist. On paper they're remarkably close. Both are all-aluminium Italian fast-displacement yachts with five-cabin layouts and a similar overall length. The Sanlorenzo takes a rather different approach, though. Instead of chasing outright speed, it settles for around 20 knots and puts the emphasis on volume, offering around 470GT compared with the Mangusta's roughly 310GT. The real talking point is the remarkable three-level owner's apartment, complete with its own private plunge pool, creating a genuine owner's retreat. It's a clever piece of design, although those split levels won't suit everyone when the yacht is moving.
The Azimut Grande 44M also deserves a close look, particularly if modern design and innovative layouts appeal. Rather than stretching the yacht horizontally, Azimut builds upwards, creating a four-deck arrangement with the owner's suite occupying an entirely private upper deck. That frees the whole forward section of the main deck for a huge social living space, giving the yacht a very different feel inside. Underway it's a different philosophy too. Twin MAN engines and Azimut's efficient Dual Mode hull focus on refinement, efficiency and lower emissions rather than outright pace, topping out at around 17 knots. It's a beautifully thought-out yacht, but if covering ground quickly is high on the priority list, the Mangusta's extra nine knots make a surprisingly big difference to the way you'll cruise.
Then there's the Custom Line 140, another yacht that leans much more towards the sporty end of the market. Like the Mangusta it has an aggressive profile, shallow draft and a real appetite for performance, although it achieves its 21.5-knot top speed with a far more conventional pair of MTU engines driving a lightweight planing hull. It's a wonderfully exciting yacht to drive and carries much of the same sporting character, but there's a trade-off. Range drops to around 1,850 nautical miles, making it far more suited to regional cruising than extended passages. If weekends in the Mediterranean or Caribbean are the priority, it's a superb alternative.
