Just shy of 18 metres in length and stretching more than 7.5 metres across the beam, the Prestige M7 is an undeniable statement in the motor yacht world. But raw dimensions only tell part of the story. What sets this boat apart is the thinking behind it: Prestige designed the M7 as a dedicated multihull motor yacht from the ground up, drawing entirely fresh plans rather than adapting an existing sailing catamaran. That distinction is not a marketing footnote. It shapes everything from the hull lines to the way the boat moves through water.
Built purely around the concept of efficient displacement cruising, the M7 carries none of the compromises that come with repurposing a sailing platform. The wide stance delivers a stable, level ride in open water. The twin hulls are shaped to minimise drag rather than carry sail loads. And the experience on board, according to Prestige, feels less like being aboard a vessel and more like occupying a well-appointed villa at anchor.
Brand director Jean-François Lair describes the M7 as an expression of the company's "DNA," life at sea characterised by understated luxury, a natural flow between spaces, and an unhurried pace. Performance for its own sake was never the objective. In his words, "the M7 represents a bold step forward… where comfort, elegance and innovation come together in perfect harmony." The pitch is clear enough: less time chasing wakes, more time watching the anchorage settle into evening.
The exterior and structural design comes from a collaboration between Garroni Design and Marc Lombard Yacht Design, with balance and real-world practicality as the guiding principles. The bows carry a clean, raked profile. The flybridge sits proportionally above the saloon without overwhelming the overall form. Hull volume is generous without the design tipping into something heavy or ungainly.
Prestige puts the main deck living area at 112 square metres, a number that is difficult to internalise until you are actually moving through the space. In practical terms, it represents roughly double the interior volume of a comparable monohull. The deck is organised into three distinct zones: a sheltered forward area combining sun pads and a saloon, side decks fitted with continuous handrails for safe movement underway, and a recessed aft cockpit configured for relaxed entertaining or simply watching the world go by.
Up on the flybridge, the helm station has been pushed slightly towards the stern, freeing up more forward deck space for sunbathing. A hardtop provides shade without visually dominating the structure above. Inside, the design team has chosen light tones and quality materials throughout, the overall effect being calm and considered, somewhere between a beach house and a well-loved home.
Prestige offers flexibility in how the M7 is configured. The standard arrangement accommodates eight guests with two crew, though an additional skipper's berth is available to owners who prefer a more professionally managed operation. Given the boat's displacement credentials and cruising range, the M7 suits both private ownership and managed charter programmes with equal ease.
Power comes from twin Volvo D8-550 V-drive diesels, each producing 550 horsepower. Together they push the M7 to a cruising speed of 17 knots, with a top end of around 20 knots. Those are solid numbers for a yacht that weighs in at just over 39 tonnes light and 51 tonnes fully loaded. The 2900-litre fuel tank supports a cruising range of approximately 290 nautical miles, a figure that reflects the efficiency Prestige has prioritised across its M-Line rather than raw power output.
A draft of just 1.55 metres adds further versatility. The M7 can push into shallower anchorages and tuck behind reef shelves that would be off limits to deeper-keeled alternatives, broadening the range of destinations available to her owners.
The M7 joins the M48 and M8 as the third model in Prestige's dedicated multihull range. It does not claim the title of largest in that trio, sitting just below the M8's 60-foot length, but it occupies a meaningful position in the line-up and extends the programme in a logical direction.
Running through the entire design of the M7 is a consistent idea of home. The layout decisions, the material choices, the lighting, the way circulation works from one space to the next, all of it suggests a place to inhabit rather than simply a vessel to travel aboard. Product marketing manager Alessandro Tollini frames it directly. "We haven't innovated to impress," he says. "We've innovated to enhance the onboard experience."
The specifications that underpin the M7 bring that philosophy into concrete terms. Length overall is 17.94 metres. Beam is 7.54 metres. Draft sits at 1.55 metres. Cruising speed is 17 knots, maximum speed around 20 knots, and range at cruise is 290 nautical miles. Fuel capacity is 2900 litres, water capacity 760 litres, and displacement runs from 39,499 kilograms light to 51,457 kilograms fully loaded. Power is provided by two Volvo D8-550 V-drive engines, with design credited to Garroni Design and Marc Lombard.
The M7 will make its world premiere at the Cannes Yachting Festival 2025, having been previewed earlier at Beaulieu-sur-Mer.
