Aquila Power Catamarans 42 and 46 Coupes Make Debut at Miami International Boat Show CLEARWATER, FL (January 6, 2025)— Aquila Power Catamarans is...
The Aquila Hydro Glide® Foil System is transforming the boating experience by enhancing performance, fuel efficiency, and ride comfort across various Aquila power catamaran models. What began as an optional feature on the 36 Sport has evolved into a standard inclusion on the new 42 and 46 Coupe models, with optional availability on the 42 Yacht, 50 Yacht, and capability for the 70 Luxury.
The 36 Sport power catamaran is widely regarded as the leading production foiling boat in the world. After years of watching this technology deliver incredible results, we knew the new Coupe series deserved the same advantage from day one.
This evolution reflects our commitment to bringing proven technology to more owners.
"When we started developing the Coupe series, we knew we wanted to include foils as an option for owners," says Jean Raas, chief product officer & chief executive officer of Aquila USA. "We learned a lot from the experience of offering foils on our 36 Sport power catamarans. Getting the shape right was an extensive process of trial and experimentation, but the performance gains we saw on those boats were incredible—upwards of 35% improved fuel efficiency. Once we realized how much our foils improve fuel efficiency and ride comfort, we decided to make them standard on the Coupes."
"Foils are tricky to get right, and even the material matters," says Raas, referring to the superior qualities of carbon fiber. "We spent a lot of time and energy getting this right, and now we want to make sure our customers enjoy the benefits."
The result? Aquila Hydro Glide Foil System comes baked right in fort he 42 and 46 Coupe power catamarans.
Here's why this technology has become such a game-changer across our foil-equipped models:
The revolutionary Aquila Hydro Glide Foil System enhances the performance, consumption, and handling of our already spectacular power catamarans. For the Aquila 36 Sport, the hydro-glide foil improves miles per gallon by 40% when compared to a competitor's 36' power catamaran and decreases the fuel consumption rate by 37%.* As reviewed by Boating Magazine: "It's hard to believe that a piece of metal with no moving parts can be the approximate equivalent of adding 200 horsepower, 100 gallons of fuel, and 100 miles of extra range." But, that's what happens when the Aquila Hydro Glide Foil System is attached between the two hulls.

Standard equipment models:
Optional upgrade models:
The strategy makes sense: Standard on models where efficiency transforms the day-boat experience. Optional where customization and choice matter most. The key is matching the right boat to your boating dreams—and that's where a conversation with your dealer becomes essential, especially since engine packages matter for foil optimization.
Boating Magazine (they test a lot of boats): "It's hard to believe a piece of metal with no moving parts can be the approximate equivalent of adding 200 horsepower, 100 gallons of fuel and 100 miles of extra range. But when it's a hydrofoil attached between the hulls of an Aquila 36 Sport power catamaran, that's the net effect."

BoatTEST (the independent testing authority): "Our tests, when compared to Aquila test numbers of an identical boat without foils, improved top speed by 6 mph or 16%—44.1 MPH vs. 38 MPH w/o foils. At 4500 RPM the 36 with foils went 31.7 MPH, 8.7 MPH or 37% faster than the boat w/o foils."

Coupe Testing Coming Soon: BoatTEST reviews for the new 42 and 46 Coupe models are coming soon. Aquila ran some preliminary tests and they show promising results: At cruise speed of 30-45 mph, the Aquila 42 Coupe with outboards & foils achieves 1.0 to 0.8 mpg—a 30% improvement over the non-foil version and nearly double the efficiency of comparable monohull competitors. The larger 46 shows similar advantages, maintaining efficiency of 0.7 mpg at 33-45 mph with outboards, pair either boat with the Volvo Penta DPI inboards in lieu of outboard engines and efficiency increases to 1.1 to 1.3 mpg.*

Here's what Morelli & Melvin figured out: Gino Morrelli and Pete Melvin didn't just wake up one day and decide to stick wings on a catamaran. These are the same minds behind America's Cup foiling technology. Turns out, decades of making sailboats fly translates pretty well to making powerboats more efficient.
The setup is beautifully simple:
Why it works so well: Traditional hulls push through water like a linebacker through a crowd—lots of effort, lots of resistance. Hydrofoils are more like a ballet dancer—lift yourself above the chaos and glide through with grace. The result? A 25-to-1 lift-to-drag ratio compared to a regular hull's 4-to-1. That's not just better; that's "wait, run those numbers again" better.
The Aquila advantage: Most foil systems need computers and active control to keep you from becoming a very expensive submarine. Ours is set-and-forget. The dihedral V-shape naturally stabilizes itself, which means you get all the benefits without needing a physics degree to operate your boat.
Beyond fuel savings: The foil system also reduces engine wear and tear by lightening the load during operation. When the engines don't need to work as hard to maintain speed, they last longer and need less maintenance. It's efficiency that pays dividends beyond the fuel dock.
The Aquila Hydro Glide® Foil System uses structural integration built into the hull design from the factory. The foil spans between the two hulls and is bolted and bonded into pre-designed recesses with marine-grade fasteners, similar to how a sailboat keel is attached.
Always avoid lobster traps and crab pots whenever possible for safety and to respect fishing operations. However, if you find yourself in an unavoidable situation, the foil sometimes helps push down lobster trap lines, which can actually help prevent them from getting tangled with your engines—a much more serious and expensive problem.
According to Pete Melvin of Morelli & Melvin Design, who designed the Aquila foil system: "The foil is actually much tougher than a propeller is. It's much thicker and stronger. So you're likely to do a lot more damage to your drive gear than you would to the foil in that situation." At speeds over 20 mph, "the foil will just cut through most organic matter in the ocean."
The foil systems are built very robustly and will likely only suffer some rope burn or minor surface damage from unavoidable contact. After any contact, inspect the foil system for visible damage and monitor performance during your next outing. If you suspect damage, have your Aquila dealer inspect the system.
Yes, and the impact on your draft varies by model but is generally less significant than you might expect. The primary foil spans the width from port hull to starboard hull and is roughly positioned 2/3 of the way back from the bow. The foil does sit slightly below the keel of both hulls. For outboard powered foil boats, the skegs on your outboard engines sit lower than the foil when your engines are in the all the way down position. For our inboard power capable foil boats, the sacrificial skeg that protects your running gear sits lower than the primary foil. So whether you're on an outboard powered boat or inboard powered boat, the foil does not sit lower than the engines (unless you have your outboard motors trimmed up).
Most foil-equipped Aquila owners navigate the same shallow water areas they always have, with normal attention to depth. Testing has shown foil-equipped models can operate in your typical shallow conditions. It is always best to be mindful of your depth to protect the foil and your running gear (props & engines) as a matter of priority. Ultimately though, there is nothing precluding you from enjoying your boat as you normally would with the foil package. Draft and strength are critical to our foil designs so you can enjoy your time on the water as you normally would. We do not recommend beaching boats with foils, but you can certainly get into very shallow water.
In most cases, your existing boat lift planning will work fine with a foil-equipped Aquila. Since your engine skeg extends further than the foils when engines are down, your lift requirements are usually determined by your engines, not the foils. Most conventional boat lift systems have adequate clearance for foil-equipped models.
Adding aftermarket Aquila Hydro Glide® Foil System may be possible depending on your specific Aquila model, hull number, and often the type of engines installed.
The hull mold must include necessary structural reinforcements, as you need recesses in the hull plus reinforcements to attach the foils, much like a sailboat keel. This requires professional installation and specialized marine expertise. Reach out to your local Aquila dealership for evaluation, as they can determine compatibility based on your specific model, hull number, and engine configuration, and handle the installation process if your boat qualifies.
The decision comes down to your boating style, typical operating speeds, and priorities for efficiency versus simplicity. Foil systems generally start providing benefits in the mid-teens mph range and are optimized for higher cruise speeds, with efficiency gains varying by model—the 36 Sport typically sees 30-40% efficiency improvements, while our yacht models achieve closer to 15% efficiency gains.
Choose foils if you cruise at higher speeds regularly, value significant fuel efficiency improvements, take extended cruises where increased range matters, want cutting-edge technology, or plan to keep the boat long-term since efficiency savings compound over years. The technology has proven popular with many Aquila owners who appreciate the performance benefits.
Skip foils if you cruise leisurely at lower speeds (the standard Aquila hull should be all you need), primarily day-boat in local waters, frequently navigate very shallow waters, prefer maximum simplicity, or have budget considerations since the foil system represents a significant upfront investment.
The sweet spot for foils is if you enjoy running your boat at higher cruise speeds, plan on covering a lot of miles and value the efficiency and range gains that come with reducing drag and lifting a significant portion of the boat's weight out of the water. Your Aquila dealer can help analyze your specific boating patterns and determine whether foil benefits align with your usage profile and the capabilities of your specific model.
Nope. The beauty of fixed foils is that they're completely transparent to operate. You drive the boat exactly the same way. The foils just make everything you're already doing work better.
For weekend warriors who want efficiency baked in: 42 or 46 Coupe with standard foils. Zero decision fatigue, maximum fun per gallon.
For yacht owners who like to customize their experience: 50 Yacht or 42 Yacht with optional foil upgrade. Build your vessel exactly how you want it, with the option to add serious range when adventure calls.
For the performance enthusiasts: 36 Sport with optional foils. Very popular choice - run smaller engines while maintaining the same speed as larger engines, dramatically reducing fuel consumption. This is where the foil story began and continues to evolve.
For the luxury adventurers: 70 Luxury with foil capability. When your dreams require the ultimate in space and performance, the technology is ready when you are.
The bottom line: Talk to your dealer. Engine packages matter for foil optimization, and they'll help you find the perfect match for your waters and your adventures.
Talk to the experts: Your local Aquila dealer knows which configuration makes sense for your boating style, your waters, and your adventures.
