It's Friday afternoon. You're leaving the office early, heading to the marina with your wife and another couple. The plan is simple: anchor, swim, eat well, and wake up Sunday without an alarm. No crew. No stress. Just four adults who want space, comfort, and a boat that doesn't require a professional to enjoy.
This is the exact scenario the Prestige M48 was designed for.
The M48 opened the M-Line, Prestige's power-catamaran range, and it is not a sailing cat with engines bolted on. It is a power catamaran built by people who understand how monohull owners actually use their boats — a 48-footer with the main-deck volume of a much longer monohull and a specification a same-length monohull cannot match.
Who It's For
The M48 is for the owner-operator who wants to cruise the Bahamas or the Keys without hiring a captain. It's for the couple who sold their express cruiser and realised they don't miss the speed, but they do miss the weekends. It's for the family that wants three real cabins, not a V-berth and two guest spaces that feel like afterthoughts.
This is not a boat for someone chasing 40 knots. The M48 tops out at 19 knots and cruises at 16, and Prestige describes the usable cruising band as eight to eighteen. If that sounds slow, you're not the buyer. If it sounds like freedom, keep reading.
The ideal owner values layout over speed and understands that a 48-foot cat on a 19' 7" beam spends its space very differently from a monohull of the same length.
Design and Layout: Where the M48 Wins
The beam is the whole point. Nineteen feet seven inches on a 48-foot hull produces a main deck Prestige uses for an exterior saloon that runs more than nineteen feet across, with several seating configurations for different parts of the day: lounge in the afternoon, dining in the evening. Forward on the deck there's a second, more sheltered saloon for a quieter conversation; above, the flybridge; aft, a mobile swim platform for diving and for getting a tender in and out.
Prestige draws the boat in three-stateroom / three-bathroom and four-stateroom / four-bathroom versions, and on this beam both are real rooms rather than compromises. The owner's cabin is forward and full-beam, with a king berth framed by a desk and a sofa. The two guest cabins have full standing headroom and their own view of the water, and each cabin in the standard layout has a separate shower — a specification that at 48 feet on a monohull is essentially unavailable.
Large windows light the cabins, and the galley is specified to feed everyone aboard rather than to make coffee. Fresh water is 159 US gallons, the calorifier 16, and the holding tank 46. At anchor with six or eight people aboard, water is the number that runs out first — plan the week around it.
Philippe Briand drew the hulls and Garroni Design the boat.
Performance: Slow is the New Fast
Prestige quotes a 16-knot cruise and a 19-knot maximum at full load, and describes the usable cruising band as eight to eighteen knots. That band is the honest description of the boat: it is not a fast yacht, and the speeds are quoted in the condition you will actually run it in.
Power is twin Volvo Penta D4-320 on V-drives. Six hundred and forty horsepower total on a 48-footer is the number to sit with. The monohull flybridge boats of similar length in Prestige's own range carry considerably more — the 420 takes twin Cummins QSB 6.7s at 380 or 425 hp a side, and the F4.3 twin Volvo D6-440s. The M48 does the same job on smaller engines because two slender hulls take less pushing than one wide one. Prestige's own material puts the fuel saving against a monohull of equal living space at 25 percent, and the CO2 reduction at 30 percent against a motor yacht of equivalent length.
Draft is 3' 11", which for a boat this wide is genuinely shallow-water access. Maximum air draft is 19' 4". Light displacement is 41,092 lbs and full load 57,242 lbs.
Fuel is 317 US gallons. On sea trial run the boat at 16 knots, then again at 10, and have observed burn recorded in writing at both. A catamaran's consumption curve is the reason people buy them, and it is worth documenting on your own hull with your own load.
The Ownership Conversation
The M48 sits at the entry point of a four-boat range alongside the M6 and below the M7 and the M8 EVO. It exists to answer a question the F-Line cannot: how to get four cabins and four bathrooms, or three of each with separate showers, onto a hull short enough for an ordinary marina slip.
The nearest comparison is inside the range. Prestige publishes the M6 on the same footprint — 48' 6" overall, the same beam, 3' 11" draft, 317 gallons of fuel, 159 of water, the same CE categories and the same six-or-eight-plus-one accommodation. The difference is the engine package and the generation of the interior: the M48 runs Volvo D4-320s and the M6 D6-380s. Same footprint, different presentation.
Outside the brand, the Aquila 46 Yacht at 47' 2" and the Aquila 46 Coupe at 47' 4" are the closest American cross-shops, and the Horizon PC52 at 53' 2" is the step up in size. What separates the Prestige is the interior programme and the finish level Garroni brings to it — a French motor-yacht interior on a catamaran platform rather than a charter cat with a nicer galley.
The practical constraint is beam. Nineteen feet seven inches is a wide boat, and slip availability and the rate card are a real part of the ownership decision. Confirm both before you sign anything.
Where to Start
The Prestige M48 is not for everyone. It's slow and it's wide. But for the right owner it is one of the best-argued boats in its class: separate showers for every cabin, a full-beam owner's suite, and a 3' 11" draft that opens the anchorages a monohull of this accommodation has to admire from outside.
Settle the three- versus four-cabin layout, confirm the marina will take the beam and at what rate, and get observed consumption recorded in writing at sea trial.
