You leave the dock on Friday afternoon with three couples and enough provisions for a week. By Saturday morning you're anchored in clear water a long way from where you started, and nobody felt the crossing. The saloon is open to the cockpit. Coffee is brewing in the galley. Someone is reading on the flybridge. This is what the Prestige M6 was designed to do — turn extended cruising into something you actually want to repeat.
The M6 is the latest addition to the M-Line, Prestige's power-catamaran range: 48' 6" overall on a 47' 1" hull, 19' 8" of beam, drawing 3' 11". Prestige describes it as designed for long, comfortable cruising — a home on the water rather than a weekender — and the interior follows that brief.
Who It's For
The M6 is built for owner-operators who want to cruise longer and farther without hiring crew. If you've been running a 45-foot express and you're ready to stay out for a fortnight rather than a weekend, this is the conversation. The 3' 11" draft on a boat this beamy is real shallow-water access — the Bahamas bank, the thinner ICW cuts, the shoal-side anchorages.
This is also the boat for families who have outgrown the weekend cruiser but aren't ready to commit to a 60-footer with professional crew. Three cabins with three heads means real privacy, and the full-beam owner's suite is genuinely livable, with a desk, a sofa and enough hanging space that you can pack for two weeks.
The M6 appeals to the cruiser who values comfort over pace. Prestige positions the M-Line around gentle, efficient cruising rather than speed, and the engine choice reflects that. If you need to run 35 knots to feel satisfied, look elsewhere.
Design and Layout: Space That Actually Works
The full-beam owner's cabin is the room the boat is built around. Prestige has drawn it as a private haven with generous volume and an intimate feel, and specified it properly — additional hanging lockers, cleverly designed furniture, a comfortable sofa and a desk, all integrated into the layout rather than bolted around it.
The galley sits at the center of daily life, fully equipped and positioned so that cooking is part of the day rather than a task done out of sight. Prestige designed the whole interior for long cruises rather than weekends, and it shows in the storage: copious, and thought about.
Movement through the boat is the other thing to notice aboard. Each living space is laid out with an intuitive flow and a natural continuity between interior and exterior, so the saloon, the cockpit and the deck read as one area when the doors are open. Prestige publishes three layout plates: flybridge with hardtop, main deck and lower deck.
The finish is warm rather than clinical — soft tones, woodwork, rattan details, enveloping shapes. Fresh water is 159 US gallons and the calorifier 16; with six to eight aboard for a week, water is the tank that decides the schedule.

Performance: Efficiency Over Ego
Power is twin Volvo Penta D6-380 on V-drives — 380 hp a side, 760 hp total on a 48-foot catamaran. Prestige positions the M-Line around gentle, efficient cruising rather than speed, and the engine choice reflects that: two slender hulls need less pushing than one wide one, and the brand's own material puts the fuel saving against a monohull of equal living space at 25 percent.
Set against the M-Line's other 48-footer, the picture is clear. The M48 shares the same 48' 6" length, the same 3' 11" draft, the same 317 gallons of fuel and 159 of water, and the same CE categories, but runs Volvo D4-320s. The M6 carries 60 more horsepower a side on the identical footprint.
The catamaran platform delivers stability at anchor and underway. There is no rolling at rest, which matters when you're spending nights on the hook, and the wide beam and twin hulls damp motion that would send a monohull pitching. Handling is predictable; twin engines set well apart give genuine manoeuvrability in tight spaces.
Beam is 19' 8": confirm your marina will take it, and at what rate, before you sign anything, because multihull berth pricing is its own conversation.
Fuel is 317 US gallons. Take the trial seriously: hold the boat at the speed you intend to cruise, then again slower, and have observed consumption and sea state recorded in writing at both. On a catamaran the consumption curve is the reason to own one, and it is worth documenting on your own hull with your own load.
The Ownership Conversation
The M6 sits in Prestige's four-boat M-Line, alongside the M48 and below the M7 and the M8 EVO. Prestige runs the line as a separate proposition from the F-Line monohulls rather than as a variant of them.
The comparison that matters most is with the M48. Prestige publishes them on the same footprint: 48' 6" overall, the same beam, 3' 11" of draft, 317 US gallons of fuel, 159 of water, CE categories B12 / C14 / D16, and accommodation for six or eight plus one. What separates them is the engine package — D6-380s here against D4-320s on the M48 — and the generation of the design, which on the M6 is the newer, warmer interior programme with rattan and woodwork detailing.
Outside the brand, the Aquila 46 Yacht at 47' 2" is the closest American cross-shop on size, the Aquila 50 Yacht at 52' 2" the step up, and the Horizon PC52 at 53' 2" the bigger, more custom answer. The Prestige case against all of them is the interior: a French motor-yacht cabin programme on a catamaran platform.
The M6 is designed for owner operation, which is a real advantage at this size. You can handle the boat with two people, engine-room access is good, and the Volvo D6 is one of the better-supported diesels you can buy.
Where to Start
The Prestige M6 is a serious cruising platform for owners who prioritise comfort, space and time aboard over pace. If your cruising plans involve extended trips, shallow anchorages and nights away from the dock, it deserves a close look.
