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. At just under $1 million base, the 42 Coupe undercuts comparable flybridge cruisers by $200,000-$400,000 while delivering similar interior volume and better performance. Resale should hold strong given Aquila's track record and the growing demand for owner-operated catamarans in the 40-45 foot range. Maintenance costs are 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.
Base price is around $980,000, pushing past $1.2 million with options and the inboard power package. Running costs stay predictable with the standard outboards: budget $2,000 to $3,000 per engine for annual Mercury Verado service, and 40 to 50 gallons per hour at cruise, so an aggressive weekend runs $800 to $1,200 in fuel. The optional Volvo Penta D6 440 inboards add complexity and cost, but buy you redundancy and a more traditional feel. Sea trials run out of Fort Lauderdale.
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, burning around 1.5 to 1.6 miles per gallon 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 those numbers possible at speed. Burn at cruise runs 40 to 50 gallons per hour depending on load, so a hard weekend of running is real money.
