At nearly 18 metres long and more than 7.5 metres across the beam, the Prestige M7 arrives as a substantial presence in the motor yacht market. Yet, its emphasis isn’t just on size. Prestige has made a deliberate move here — designing a multihull from scratch, not by adapting a sailing cat, but by drawing clean lines and new plans based solely on the idea of what a multihull motor yacht could be.
That distinction matters. Rather than compromise between sail and engine, the M7 is engineered for efficient displacement cruising. The wide stance gives it a level ride at sea. The twin hulls reduce drag. And the onboard experience is said to be more akin to a villa than a boat.
What makes it a true multihull motor yacht?
Jean-François Lair, Prestige’s brand director, says the M7 reflects the company’s “DNA” — life at sea marked by understated luxury, seamless flow, and a gentle rhythm. It’s not about chasing performance, he adds. Instead, “the M7 represents a bold step forward… where comfort, elegance and innovation come together in perfect harmony.”
Put simply, it’s about less wake-chasing, more anchorage-watching.
The M7 has been shaped by Garroni Design and Marc Lombard Yacht Design with a focus on balance and practicality. The bows are nicely raked, the flybridge sits neatly over the saloon, and the hulls carry their volume without looking boxy or overblown.
112 square metres of living space on the main deck
Prestige reports 112 square metres of living space on the main deck — a figure that’s hard to picture until you walk it. That’s about twice the volume of a monohull of similar length. The main deck is split into three zones: a protected forward area with sun pads and a saloon, side decks with continuous handrails, and a recessed aft cockpit made for lounging or entertaining.
The flybridge sees the helm station pushed slightly aft, leaving more forward sun-lounging space. A hardtop keeps things shaded without dominating the lines. Inside, the use of light tones and noble materials lends a calm, beach-house aesthetic.
Prestige also offers a range of layout options. While the default is an 8-berth guest configuration with two crew, an extra skipper’s berth can be added depending on how the owner wants to run the boat. Given its displacement and range, the M7 is just as likely to be privately owned as professionally managed.
Performance and range
The Prestige M7 runs twin Volvo D8-550 V-drive diesels, delivering 550hp each. That gives her a cruising speed of 17 knots and a maximum of around 20 knots — respectable numbers for a yacht that tips the scales at over 39 tonnes light and 51 tonnes fully loaded.
The fuel tank holds 2900 litres, and at cruising speed, the M7 can cover approximately 290 nautical miles. That figure reflects Prestige’s focus on efficient hull design and lower fuel burn — a trait consistent across the M-Line.
The draft is just 1.55 metres, meaning the M7 can comfortably anchor in shallower harbours or behind coral reef shelves, adding to her go-anywhere nature.
The Prestige M-Line: now three-strong
The M7 joins Prestige’s M48 and M8 as the third model in the builder’s multihull line-up. It’s not the largest of the trio to date and comes just shy of the M8’s 60-foot length.
If there’s a recurring theme in Prestige’s approach to the M7, it’s the idea of “home.” Everything about the layout, the materials, the lighting, and the flow of movement on board suggests a place to live — not just to travel.
“We haven’t innovated to impress,” says product marketing manager Alessandro Tollini. “We’ve innovated to enhance the onboard experience.”
Whether moored in the Bay of Islands or cruising the Marlborough Sounds, the Prestige M7 offers something quietly compelling. It doesn’t shout its credentials — it invites you aboard and lets you breathe.
