The Bluegame BGF45 has made its world debut at the Cannes Yachting Festival 2025 as the brand’s first multihull and the debut model of a new range. At 45ft (14.15m), it's a day-boat with a technical edge rarely seen in this sector.
The foil is the talking point, claimed to cut drag and lift efficiency by more than 30%, but the question is whether it makes a tangible difference at sea. In this review, we’ll look at how it performs underway and uncover the details that shape life on board to find out if Bluegame’s experiment lives up to its billing.
Test & Review Video
At Slow Speeds
At low speeds, the BGF45 is easy to manage. The IPS joystick takes the strain, with a light, accurate response that makes close-quarters work less stressful than you might expect from a 5m beam multihull. Visibility from the helm is good thanks to the big windscreen and open sides, so you can keep a close eye on the dock. The lack of higher cleats aft is a slight problem when mooring Med-style, but in terms of control, the boat feels nimble and predictable at displacement pace.
At Sea
Once clear of the marina, the character of the hulls and foil comes through. The BGF45 sits comfortably anywhere between 20 and 30 knots, with little penalty in fuel burn as you rise through that band. At 25 knots, the combined consumption is around 130 litres an hour, edging to 150-160 litres at 30 knots. Range remains in the 300nm bracket, even at that fast cruise.
The ride is strikingly soft for a boat of this size. Heading upwind into a chop at 22 knots, the hulls and foil together cushion the motion and keep spray well clear of the deck. Only in the wake of larger boats does it slam, and even then, it feels more cushioned than a comparable monohull.
It's difficult to decipher what is most effective between the slender hulls and the foils, but the combined package is impressive. Upwind, especially there's a cushioned sensation as the boat romps through the crests, and it's very quiet, even at the upper reaches of the rev range.
The Humphree trim system gives it an element of heel in the turn, so rather than sliding flat, it banks gently, avoiding that tabletop sensation that can sometimes throw the crew sideways on multihulls. The presence of the foil doesn't add any complication to the driving experience; it feels like any other IPS boat with light steering and a hint of heel that makes it a very rewarding machine to pilot through a chop.
Do The Claims Stack Up?
The question is, do the slender hull and foil mount to a boat that is more efficient than a regular monohull at a given speed?
Handily, Bluegame has one of those in its stable in the form of the BG42, the first model it ever launched, which is powered by an older version of the IPS5650 with 510hp per side (slightly more than the BGF45).
In our own sea trial of the BG42, at 25 knots, it consumed just over 100l/h, compared to the 130l/h of the BGF45. On the face of it, the folier doesn't seem as though its efficiency is anything to write home about. However, consider this: the 45 is nearly 2m longer than the 42 and 0.5m wider, with a displacement of 17 tonnes, compared to around 11 tonnes for a similarly specified 42.
Not only that, the BG45 has slightly less power and much more comfortable accommodation with two decent separate cabins with their own bathrooms. With this context, it appears that the design of the 45 does hold some efficiency benefits, though what's down to the foil and what's down to the shape of the hull is hard to decipher.
The BGF45 is the first of a new breed for Bluegame, the opening model in the BGF line and the brand’s first multihull, with the larger BGF55 already announced to follow. It takes direct inspiration from Bluegame’s America’s Cup work, where the team developed a hydrogen-powered foiling chase boat capable of running at 50 knots. Here, that same foil technology is adapted for leisure use, fixed between the hulls to lift, stabilise, and cut drag. Bluegame claims efficiency gains of more than 40%, though in practice it’s the overall package - the slim twin hulls and foil working together - that gives this boat its unusually soft, dry ride.
The project is the result of some heavyweight collaboration. Luca Santella, Bluegame’s founder and Head of Product Strategy, steered the concept, while Zuccon International Project shaped the design. Hydrodynamic specialists Mario Caponnetto and Francis Hueber, who were also behind the America’s Cup chase boat, helped refine the hull form. Add in Volvo Penta for propulsion, Humphree for trim control, and the Sanlorenzo parent group for build quality, and you have a craft that mixes race-bred tech with superyacht-level execution.
Construction reflects that dual focus on performance and quality. The hull and superstructure carry carbon fibre elements to trim weight, and honeycomb panels appear in the cabinetry to shave kilos wherever possible. Even the heads have carbon fibre toilets, a quirky but telling detail from a yard looking to save every gram. At around 17 tonnes fully loaded, the BGF45 isn’t light by day-boat standards, but every weight-saving measure helps when the aim is to semi-foil.
Alongside the two main cabins, there’s a third void in the starboard hull that can technically be fitted out as an extra cabin. It does feel oversized for simple stowage, but not entirely convincing as a guest or crew space. In practice, most owners will probably keep it as a generous storage bay for bulky kit, a pragmatic solution on a 45-footer where open deck space is so central to the design.
The finish is unmistakably Bluegame under Sanlorenzo’s wing. Teak lines the decks, curves are clean and carefully executed, and the fittings feel engineered rather than styled for show. The look is still bold and disruptive - all very much Bluegame.
Engine Room
Being a multihull, the BGF45 has a separate engine room in each hull. The starboard side is also home to the generator. Access is via deck hatches in the aft cockpit, and once inside, you find a neat, well-insulated space.
Headroom isn’t generous, especially over the engine, where it feels tight, but these are compact motors, so moving around them isn’t too difficult. Daily checks like dipsticks, filters, and sea strainers are all in reach, and access to the pods is particularly straightforward.
The installation looks tidy and well finished, with plenty of sound insulation. That goes some way to explaining how quiet the boat feels out on the water. For long stints of heavy maintenance, it won’t be the most comfortable space, but for an owner carrying out routine checks on a 45-footer, the layout makes sense.
Owner’s Cabin
The owner’s accommodation is based in the starboard hull, but part of it stretches across the bridge of the boat into the port side. That cross-hull arrangement gives it far more volume than the guest cabin opposite, and it feels a step up as soon as you slide back the roller-shutter style door and step down.
The ensuite bathroom is slightly bigger than the guest cabins in the other hull, still with a carbon-fibre toilet (part of the weight-saving measures), a separate shower cubicle, and excellent headroom. The décor is dark and moody, but it’s softened by extra lighting and a skylight overhead. With the ceiling spots on, the space feels deliberately atmospheric rather than simply gloomy.
Storage runs the length of the forward bulkhead, neatly finished in honeycomb panels – another of those weight-saving details that crop up throughout the boat. The bed is set into a raised platform. Once you’ve clambered in, it’s a comfortable spot, complete with bedside lighting and shelving, but it is a bit of a scramble to get down onto it.
It’s not a sprawling suite, but the clever use of both hulls means this cabin has genuine presence. For a boat of this size and purpose, it feels like a proper place to turn in at the end of the day.
Guest Cabin (Port Hull)
Drop down into the port hull, and you'll find the guest cabin. It’s a double, with its own ensuite, but you’re working within the confines of a slender hull. The bed is a decent size for the space, though not one you’d choose for long stretches aboard. For the odd overnight or weekend, it’s perfectly serviceable.
The bathroom is a good effort, with its own separate shower cubicle and a carbon-fibre toilet - part of the boat’s weight-saving measures? Headroom is surprisingly generous thanks to the high freeboard, so you don’t feel hemmed in.
Storage is fair: a hanging locker, a shelf, and charging points, though the person sleeping inboard will have to climb over their cabin-mate to get out at night. Natural light is limited. Instead of curtains or blinds, Bluegame uses external grilles that shade the glazing and keep the lines of the boat clean, but they do leave the interior on the dark side.
It’s not a space designed for weeks of cruising, but as a guest cabin on a big day boat, it does the job with reasonable comfort.
The helm is set up simply, with most controls run through a central multifunction display. Physical buttons are kept to a minimum, so the dash is kept fairly uncluttered. The steering wheel itself feels good in hand, light and easy, thanks to the IPS system.
The seat has plenty of style but isn’t perfect ergonomically. Sat down, it’s a comfortable driving position with a clear view ahead, but standing feels less natural as you don’t get the easy bracing you might expect.
Protection is strong, though. The large windscreen shields the skipper well, and even though there’s an open gap at the top, you only get a light breeze rather than being blasted. It keeps the cockpit airy without leaving you exposed.
The aft end of the BGF45 is built around a hydraulic transformer platform. It’s the one-stop solution for boarding, swimming, and tender launch. Dropped into the water, it creates a shallow set of steps that make climbing in and out straightforward, and it’s rated for 200kg, which is fine for an inflatable tender or toys, but not a heavy jet rib.
The link between this platform and the aft sunpad is well thought through. Beneath the pad sits a cavernous locker that swallows paddleboards, diving gear, or even a small inflatable. It’s a genuine boot space, easily big enough to take the clobber that comes with a long day at anchor. The mechanism itself is quick, which matters on a boat like this, as when the weather's good, you'll want the toys loaded, press the button, close the hatch fast, and be away.
When the platform is down, it doesn’t disrupt movement across the transom either. Teak decking continues right through the area, so it feels like a proper extension of the cockpit rather than a separate add-on. The whole aft section doubles as a generous sunbathing zone too, and three or four people can stretch out comfortably across the pad.
Cockpit
The cockpit is set up around a huge dining table, which folds or extends, spreading wide enough for a big group, exactly the sort of setup you’d expect on a day boat designed for long, lazy lunches.
Behind the dinette, tucked into the starboard side, is a big storage void. Technically, it can be specified as a small cabin, but in reality, it works best as deep, practical stowage. It keeps the lines clean while still giving you somewhere to throw bulky kit, which neatly captures Bluegame’s balance between style and function.
This is also where the outdoor galley sits, with the same teak fascias you see elsewhere. The lid splits and lifts to reveal a well-sized sink, a big chopping board, and an induction hob, though you could swap in a griddle if that suits your cooking better. Below are a fridge, an ice maker, and more storage. It’s a proper prep space, not just a token arrangement, with plenty of counter space to work on.
The hardtop provides good shade over the cockpit, though it isn’t especially high. Anyone well over 6ft may feel the headroom brushing close. Opposite the galley, there’s a useful open tray for phones, sunglasses, and the other small things that tend to end up scattered across a deck. Flat surfaces like this might not be glamorous, but they do make life easier.
Side Decks & Foredeck
From the cockpit, steps lead you up to the side decks, where some clever detailing becomes clear. The windscreen stretches a long way aft, so even those seated behind the helm benefit from extra shelter. Slim carbon-fibre poles with tensioned lines mark out the walkway. It’s a lightweight system, but it does the job, and it keeps the look clean.
As you climb forward, an integrated handrail sits neatly inside the moulding. It falls naturally to hand, making the step up onto the side deck feel secure. Once forward, more substantial rails run along the bulwarks. There’s even scope to treat this area with a bit of adventure gear – fit roof racks and you could stow paddleboards up here without fuss. The styling has a bit of that “expedition” flavour to it, and the foredeck can play along.
Right at the bow, the arrangement is simple but effective. A broad sunpad takes centre stage, a lightwell feeds daylight down into the owner’s cabin, and the anchor gear is neatly enclosed in its locker. The teak finishing across this area is beautifully done, and the curve of the coachroof is smooth and carefully shaped. That Sanlorenzo parentage is plain to see in the way the lines come together.
The BGF45 comes in at around €1.8 million before tax, though by the time you’ve added options, most boats will sit closer to €2 million. That’s a serious figure for a multihull of this size, even one carrying Sanlorenzo’s stamp of quality.
That said, the quality rings out in the construction technique, engineering, and the use of materials on board, and there's a fair bit of cost that goes into developing a concept like this.
It may be referred to as a day boat, but the BGF45 is much more than that, given the standard of the accommodation. In good weather, a couple could live on board for an extended period of time, though it's not that well set up for rainy days, given you want to be able to live on deck.
Our Verdict
The BGF45 is a clever link to the America’s Cup, and out on the water, the effect is hard to dismiss. With only a short sea trial, it’s impossible to separate foil effect from the natural efficiency of the slim twin hulls, but as a package, the ride is softer, the decks stay drier, and the efficiency figures are strong across a wide cruising band.
What that means in practice is a day boat, or a weekender, that really can cover ground quickly and comfortably. It also carries the build quality you’d expect from anything wearing the Sanlorenzo badge.

Rivals to Consider
The Solaris 44 Open is a monohull with two good cabins below and certification for up to 12 on board during the day. It can hit around 39 knots with IPS 650s and settle into a mid-20s cruise. What sets it apart is deck space: the folding bulwarks open into terraces, and there’s even an optional garage beneath the aft deck. Compared to the BGF45, it offers more of that classic “social platform” feel, but it lacks the foil and twin-hull efficiency that make the Bluegame such an unusual package.
Wajer’s 44 HT is more pared-back in its accommodation, with one main cabin and a roofed cockpit that slides open when the weather allows. It’s designed as a premium day boat first and foremost, running to the high 30-knot mark with IPS power and cruising comfortably in the 20s. The appeal is all about sleek looks, flawless finish, and the flexibility of that hardtop. Against the BGF45, it feels lighter and more elegant, but without the interior volume or the semi-foiling ambition.
The Aquila 47 Molokai is another multihull, though one with a very different focus. Twin 600-hp outboards push it towards 40 knots, and the wide decks are set up for adventure - with live wells, lockers, and big insulated boxes that can take fishing gear as easily as watersports kit. Cabins are minimal, tucked under the console rather than split across the hulls. Where the BGF45 leans into luxury and ride comfort, the Molokai trades that for rugged utility and open deck space.
