Part of the Aquila Coupe series — see how owners step up through the lineup.
The 42 Coupe represents Aquila's most refined execution of the owner-operator power catamaran concept. The build quality is solid, the carbon fiber foil system works as advertised, and the outboard configuration eliminates the engine room maintenance headaches that plague traditional powercats in this size range. Aquila's own figures put it at roughly 40 knots top and a 30-33 knot cruise, and the efficiency at that cruise is what makes extended runs practical without constant fuel stops.
This boat is for the experienced boater who wants to run their own vessel without sacrificing comfort or capability. It's not for first-time buyers who need hand-holding or owners who prefer the traditional flybridge layout. The single-level design is brilliant for couples or small groups, but if you're regularly hosting six or eight guests, the lack of a flybridge entertaining space will feel limiting. The two-cabin layout is perfect for owner use or one additional couple, but families with multiple kids will find it tight.
Market positioning is smart. The 42 Coupe undercuts comparable flybridge cruisers while delivering similar interior volume and better performance — you are buying beam and usable single-level space rather than a second deck. Demand for owner-operated catamarans in the 40-45 foot range keeps growing. Maintenance is predictable with outboards, and the shallow draft opens up cruising grounds that traditional deep-V hulls can't access. This is a boat that will age well if maintained properly.

Four adults in two private cabins, each with an en-suite head and a separate shower, plus a convertible dinette if you are running with kids. The forward VIP is a true queen berth, not a V-berth with filler cushions, and the aft cabin is nearly the same size, so nobody draws the short straw. The honest limit is water: 52 gallons. That is a long weekend for four rather than a full week, unless everyone is disciplined at the shower.
Two things set it: which power package you choose and how hard you run. The standard twin Mercury Verado V10 400 outboards are the simpler boat to own — outboard service is routine work, and repowering years from now is a bolt-off job rather than a refit. The optional twin Volvo Penta D6 440 inboards cost more to buy and more to keep, and they buy you redundancy and a more traditional feel underway. After that it is the ordinary line items: fuel from a 410-gallon tank, insurance, a slip that takes a 15-foot 11-inch beam, and annual engine service. Ask for the build sheet with every option priced line by line, and for observed fuel burn at cruise in writing rather than a brochure figure — we will get you both, and set up the sea trial, before you commit.
Two feet ten inches with the motors trimmed up — shallower than plenty of center consoles half its length. That opens up sandbars, back-country anchorages, and Bahamian flats that a deep-V of this size has to admire from the channel. It is also why most buyers choose the standard Mercury outboard package over the optional Volvo Penta D6 440 inboards. Combine it with roughly 40 knots of top speed and you reach the skinny water well before the crowd does.
Yes. Joystick docking is part of the helm package alongside twin 16-inch Garmin displays and a single-lever throttle for the outboards, and the 15-foot 11-inch beam fits standard slips. Visibility from the helm is clear in every direction, and the hardtop shades you without blocking sightlines. Twin Mercury Verado V10 400s mean you always have independent thrust at both corners. This is a boat you can bring into a tight marina solo without an audience forming on the dock.
Power and reach. The 42 Coupe is 42 feet 10 inches with twin Mercury Verado V10 400s, 410 gallons of fuel, roughly 40 knots top and a 30-to-33-knot cruise. The Aquila 46 Coupe is 47 feet 4 inches with twin Verado V12 600s, 616 gallons, about 44 knots top and a 35-knot cruise. Both sleep four in two en-suite cabins. The 42 is the shallower boat at 2 feet 10 inches with motors up; the 46 draws 3 feet 7 inches.
Approximately 545 nautical miles at 30 knots from a 410-gallon tank. That is Miami to Bimini and back with fuel to spare, or the Keys to the Dry Tortugas without a stop. The carbon-fiber Hydro Glide foil and double-stepped hulls are what make that reach possible at speed. Load, sea state and how hard you push all move the real number, so plan a long crossing on what your boat actually burns on the day rather than on a published figure — ask us and we will get you observed numbers from a hull running your power package.
