It is astonishing to think that it’s getting on 10 years since Invictus first bounced on to the scene with a puppyish little 37-footer, jewel-like in the Cannes show sunshine with its leather trim and shining chrome. It wasn’t the yard’s first boat, but it was the first with that radical retroussé snout. Its distinctive profile was easily explained: all part of its pugnacious appeal, a mark of character and individuality. And to be fair, it wasn’t as wet upwind of that bow as it looked.

A wide, head-on shot from the water looking directly at the unique, inverted bow snout of an Invictus ST550 yacht cruising at speed. The dark-hulled luxury boat pushes up crisp white wake wings on both sides as it heads toward the camera. In the background, a warm sunset glows intensely over a calm, open ocean, casting a soft pink and orange hue across the sky and creating a glistening light path on the water's surface next to a distant mountain silhouette.

A fair few Invictus snouts have ventured into the limelight since then, each one larger than the last, until at the most recent Festival de Plaisance last September we found that the once adorable puppy has grown into a 25-ton, 55-foot beast that would give a lion-tamer pause. And there were two of them: The new 550 comes in both hardtop and wheelhouse versions, on the same hull and engines—and the same lower-deck layout too. It’s arranged around a spacious master cabin forward, with head and shower compartment right up in the bow, and a double guest cabin amidships, which has sliding single berths that come together. Between them, you can opt for a galley on the port side, or a twin-bunk guest cabin.

A woman in a swimsuit and cover-up lies sunbathing on a massive, triangular grey sunpad built into the bow section. Just behind her, a spacious U-shaped grey lounge seating area features white accent pillows and two small, polished wooden dining tables facing the glass windshield of the enclosed white cabin.

There is something almost admirable in the hull’s wholly unapologetic absence of aesthetic charm. Two bold black stripes make a gallant effort to disguise its height and bulk, but are defeated.

Still, you would hope that such an imposing edifice would at least be roomy inside, and so it proves to be. Headroom ranges from a gargantuan 6 feet, 10 inches in the master to 6 feet, 4 inches in the second guest cabin, and the beds are all a decent size—even the bunks, which although a mere 26 inches wide are by some margin the longest on board at 6 feet, 7 inches. The shower in the master is big enough for two, and the guest head is perfectly adequate. Stowage space abounds. Attention to detail is everything we have learned to expect from this brand—there is even a very useful camera in the chain locker. Numerous access hatches in the sole provide plenty of opportunity for those of a beady-eyed bent to find fault with the finish. Good luck with that.

In the foreground, a premium light grey textured helm chair with an embroidered Invictus logo sits to starboard, while a matching double passenger bench is positioned to port. The sleek helm console is equipped with two large black glass multi-function displays, steering wheel, and throttle controls. Teak-planked flooring runs underfoot beneath a sculpted, dark-paneled ceiling, and large wrap-around glass windshields look out onto a calm, sunny blue ocean with a distant island hill.

Up on deck is where the model differences lie. With its carbon hardtop, the TT version will feel more familiar to Invictus aficionados, thanks to its sociable helm seating, bar, and versatile dining and sunbathing spaces aft. It’s a tried-and-true arrangement, and hard to beat. It works so well because it feels connected, whether you’re at the helm or topping up your tan. The ST550’s main deck layout is more conventional, and if you want its enclosed saloon and galley, the price you pay, not counting a one-ton weight penalty, is a definite separation between inside and outside spaces.

On the left, a grey upholstered L-shaped dining lounge features two rectangular wood-topped tables on polished stainless steel pedestals beneath a sleek hardtop canopy extension. To the right, a massive, flat sunpad lounger extends toward the stern, lined with cylindrical headrest bolsters and built-in cup holders. The open deck faces a calm, wide blue ocean under a hazy sky with a single hilly island on the horizon.

However, the foredeck arrangements on both versions of the 550 are exceptionally well appointed, so ST owners have plenty of alfresco options. And like the earlier 460, the Invictus 550 also has gunwales that fold down aft to increase deck space at anchor.

We took the ST version out of the boat show and into the Baie de Cannes for a spin, with fuel and water tanks half full, and nine crew on board. Our 550 had the more powerful of the two engine options, 725-horsepower Volvo Penta IPS950s. Invictus’s big new flagship cannot compete with its smaller sisters for zip and panache, we learned, it being altogether heavier and more ponderous. In both helm and throttle response it felt steady rather than startling. But a top speed of 33.4 knots is more than respectable, the steering felt light but positive, and the leather-clad wheel itself was a tactile treat.

To the left, a cozy light grey sofa rests against dark wood paneling below a horizontal window with soft ambient lighting. A large, floor-to-ceiling smoked mirror wall divides the room, reflecting the seating area and a beige leather duffel bag on the light oak floor. To the right, a plush double bed with a geometric patterned coverlet and an orange accent pillow sits under integrated LED ceiling strips, positioned next to a matching wood-grain cabin door.

We only had a 1- to 2-foot chop to contend with, but the way the hull’s full bow sections thumped through it suggested that in more challenging conditions you would be throttling back a little to keep your guests comfortable. We also found the ST’s windshield mullions very bulky, and the aft side windows so low that checking to port and starboard before winding on any helm was necessarily a team effort. For its superior helm visibility as well as for its lighter weight, the TT model will probably be more fun to drive.

Two twin beds with geometric-patterned coverlets and brown pillows sit side-by-side on a light oak floor, enhanced by soft under-bed LED lighting. A large mirror wall behind the far bed reflects the room, adding to the sense of space. The left wall features a horizontal window with a soft white shade, while a floating vanity desk with a backlit mirror is visible on the right next to fine wood-grain paneling.
