How does the VARA® Foil system improve fuel efficiency?
The VARA® Foil system improves fuel efficiency by generating dynamic lift that raises the hull partially out of the water. This significantly reduces wetted surface area and drag, allowing the engine to maintain speed with much less effort. On average, this streamlined performance generally leads to fuel savings of 30%-40%.
Can I install a hydrofoil kit on an existing power catamaran??
Yes, custom-built VARA® Foil kits are specifically designed for installation on both new and existing used power catamarans. These DIY-friendly kits utilize a “plug and play” four-bolt design that allows you to mount the system while the boat is in the water, on a trailer, or on a lift. The assembly is also fully adjustable, giving you the flexibility to fine-tune the foil’s position and angle to match your specific hull’s performance.
What speed increases can I expect with a VARA® Foil Installation?
All power catamaran platforms are built different. However, Installing a VARA® Foil kit typically results in a guaranteed minimum speed increase of 10% for power catamaran applications. While most installations achieve real-world gains between 15% and 30%, the specific improvement depends on your boat’s hull design, weight, and tunnel width. This boost in top-end speed is achieved by lifting the hull higher in the water to drastically reduce drag.
What kind of fuel consumption savings increase can I expect?
The VARA® Foil system typically offers fuel savings between 20% and 30% by significantly reducing hull drag. Some customers have even reported exceptional gains of up to 50% while maintaining higher cruising speeds. This efficiency is achieved by lifting roughly 40% of the hull’s weight out of the water, allowing your engine to work much less, which will increase life expectancy and decrease maintenance req’d.
What happens if I hit something with the VARA® Foil?
The VARA® Foil is designed to be extremely durable, easily handling beaching, slow-speed impacts, and debris like small limbs without issue. Like a boat’s hull or lower unit, it remains susceptible to damage from significant obstacles such as large logs or tree stumps. Should a major impact occur, the system is designed to be serviceable so you can get back on the water.
Can I trailer a hydrofoil catamaran
Yes, you can trailer a hydrofoil catamaran, but you must remove any internal trailer guides or rails to provide necessary clearance for the foil. Removing these guides not only allows for the initial installation but also ensures you have easy access to “dial in” and adjust your ride characteristics later. This modification typically makes trailering straightforward without requiring any other major changes to your setup. We highly recommend external guides on your trailer for launching and hauling that usually cost betweeen 100-200.00.
How does a VARA® Foil handle rough water?
While everyone’s definition of “rough water” differs, a VARA® Foil provides a much smoother ride than a standard power cat by offering a cushioning effect as you move through chop and waves. This upgrade increases your operational limits and comfort, though it doesn’t turn your boat into a “battleship,” so you must remain aware of your personal and vessel limits. The system essentially acts as a shock absorber, significantly reducing the jarring impacts typically felt in choppy conditions.
Is a VARA® foil hard to drive?
Actually, the VARA® Foil makes driving easier and typically takes only 15 minutes to learn once it is “dialed in” to your specific boat. You can expect to reach a “beginning master” level of understanding regarding the theory and use in approximately eight hours of operation. While it simplifies handling, becoming fully proficient allows you to maximize the system’s performance and efficiency benefits.
Why choose a hydrofoil cat over a traditional power catamaran platform?
Choosing a VARA® Foil-equipped cat transforms your boating experience by delivering a 20-30% fuel savings alongside a thrilling 15-20% boost in speed. You gain an ultra-smooth, “cushioned” ride that glides over chop while others are slamming, essentially turning the ocean into a paved highway. It’s the ultimate upgrade—giving you a drier, faster, and more economical vessel that keeps the stability you love while performing like a total beast.
Does the foil impact shallow water operation?
The VARA® Foil is specifically designed to sit above the shaft centerline of your engines, meaning if your motors can clear the bottom, your foil can too. Since the system lifts your boat higher while moving, you actually gain the ability to glide over shallows that would ground a traditional hull. It’s the ultimate “have your cake and eat it too” upgrade—maximum performance in the deep with zero to short inches of sacrifice in the skinny water.
How do I maintain my VARA® Foil system?
The system is virtually maintenance-free, requiring maintained sacrificial zinc anodes a simple fresh-water rinse or smooth sprayed bottom paint application for in salt water to prevent mineral buildup. Just keep it clean, while checking for damage periodically and it will efficiently perform season after season.
Will the foil affect how my boat handles at the dock?
Not at all—the VARA® Foil is designed to be completely unobtrusive during low-speed maneuvering and docking. Since the foil is positioned between the hulls and sits above the lowest point of your engines, your catamaran will retain its signature twin-engine pivot and control. You get all the high-speed performance benefits without sacrificing any of the low-speed agility you expect from a cat.
Does the VARA® Foil come with a warranty?
Absolutely, we stand behind our engineering with a robust warranty that covers defects in materials and workmanship ( See term and Conditions). This gives you total peace of mind that your investment is protected as you push your boat to new speeds and efficiencies. We’re committed to making sure every VARA® Foil owner is a customer for life.
Do I need trim tabs with the VARA® Foil system?
NO! The twin engine VARA® Plates don’t just replace trim tabs—they completely evolve them by giving you surgical precision over your boat’s “flight” and attitude. With a simple flick of the switch, the captain can instantly correct for side-to-side list or heel, and front to back “Pitch” keeping the deck perfectly level regardless of wind or passenger movement. It’s the ultimate “command center” upgrade, turning a once-clunky manual balancing act into a seamless, high-performance gliding experience.
