Maui Fin Company’s Hydros surf foil is the result of their strategic partnership with Kai Lenny’s The Hydrofoil Company. 

Together, these brands have designed a top-rated performance foil designed to deliver under advanced riders.

The first wings born of this collaboration were introduced in early 2018, but only in limited quantities. 

With a lot of hype surrounding this initial wing, and each iteration after, riders report having to wait months after they place their order for the Hydros. 

If you’re interested in an MFC Hydros review and considering placing your own order, read on for our product highlights. 

We’ll talk through this foil’s technical aspects and offer our thoughts on the ride this foil is capable of delivering.

Size of the MFC Hydros

The Hydros is a full carbon construction performance foil.  It features a 70-cm carbon mast with a pedestal-style mount.

Two wing options make the Hydros an appealing option for both high and low energy days on the water and accommodate a wider range of riders. 

The Medium 1075 foil is best for riding big waves, while the Large 1250 is designed for smaller wave days. 

The Medium 1075 is also best for riders who weigh less than 170-pounds, but the large Large 1250 is perfectly suited for riders weighing more than 170-pounds.

If you’re a beginner or you weigh more than 180-pounds, you might want to consider a third option in the Hydros line. 

The Hydros FW1400 is designed to generate gradual lift and to maximize control for beginners and heavier riders. 

With the FW1400, you’ll enjoy plenty of continual glide and put less than ideal wave conditions to work.  This version is best for small wave days.

The 1250 and 1075 wing sizes are available in single wing packs or a double wing pack.

When you purchase the Hydros foil, you’ll also receive all the necessary board mounting hardware and tools, 3 back wing shims – all in a high quality padded foil bag meant to keep your foil safe between rides and when traveling in search of the perfect wave.

Tech specs

The Hydros is a full carbon foil and all of its component parts are made of carbon with the exception of the bolts. 

It comes in two fuselage options, a standard 63 and a shorter 58cm fuselage. 

The keel measures 28.5-inches from board to fuselage and featured an integrated base plate that helps to lighten the foil.

The wing design of the Hydros MFS is engineered for speed.  This design includes trailing edges that taper to a fine line. 

The Hydros is a lightweight foil and the design incorporates a good deal of flex. 

Because of the degree to which the Hydros wing flexes, you’ll want to keep an eye on your keel. 

If it’s going to crack, the crack will likely be at the baseplate area as a result of flex and movement. 

Heavier riders are more likely to see flex-type damage and they are also less likely to enjoy the way the flex of the Hydros alters the foils ride on high energy wave days. 

Though the larger size foil will accommodate riders weighing more than 170 pounds,  you’ll want to make sure you are well-skilled and experienced with performance foils if you’re  a heavier rider on the Hydros. 

Hydros wing design

The wings on the Hydros are a double anhedral type.  This design is paired with a thinner foil to chord ratio. 

This is one of the thinnest wings on the market and that thinness makes the Hydros very fast while maintaining a subtle lift profile.  

Taking off is easy with the Hydros because of its angle of attack. 

On the Hydros, this angle is small and creates a fast linear lift profile to allow riders to make steeper take-offs with more security. 

Even the larger foils are very fast because of these thin wings and seem to just keep accelerating once you find the sweet spot in a swell. 

For less experienced riders, this constant acceleration can mean less control, but the tradeoff is favorable for advanced riders.

A closer look at the Hydros lift profile

Lift is an important characteristic in a foil.  It determines how much energy you’ll need to invest to get up and moving to top speed and it can also factor into the stability of the ride. 

Though a rider’s experience level and training factor in, too, aspect ratio and lift profile are key to a foil’s maneuverability and ability to carve.

The linear lift profile of the Hydros wings and the lower angle of attack mean the Hydros need more speed to lift off the water and wings will lift more slowly. 

The thinness of the Hydros’s wings generates speed that helps to compensate for the double anhedral-style lift, making this a highly efficient wing capable of incredible top speeds. 

This design will give you an immediate feeling of acceleration and you’ll notice you reach top end speeds faster.

Stability challenges with the MFC Hydros 

The Hydros is rated consistently high for its capacity to generate a lot of speed but it sacrifices some stability to provide such acceleration. 

For straight down-the-line riding, the Hydros wing style is very stable. 

When you start working in turns and maneuvers, though, you may notice the pitch and sensitivity of this foil mean you definitely have to be at the top of your game.

One reason the Hydros isn’t the most stable wing on the market can actually work in a performance rider’s favor. 

This is a super sensitive foil setup.  It is highly responsive to rider input and responds to even subtle rider cues. 

It requires a good deal of speed to get going and a lot of commitment but it offers a Ferrari-like performance on the water. 

Just as you wouldn’t put a new driver behind the wheel of a Ferrari and expect them to really enjoy the car’s capabilities, the Hydros is a foil best ridden by advanced riders who know how to make instability become an asset.

The pitch on the Hydros fuselage is another aspect that minimizes overall stability and can challenge less experienced riders. 

It is moderate in difficulty and will challenge your balance skills without changing the lateral stability of the wing. 

For slalom-style riders, this short fuselage means tighter turns.   

Turn power 

We’ve already mentioned that the Hydros is a highly sensitive and responsive foil. 

Though the turning style of the Hydros may challenge newer riders, the overall design of the Hydros makes it a turning machine.

The Hydros will eagerly lay over on edge, by this effect is multiplied with the Hydros’s smaller wing size, creating a smaller turning radius. 

The shorter fuselage of this foil setup, too, promotes its turn ability, adding the sort of speed you need to turn on a dime at what feels like G-force.  

This isn’t a traditional wing design, though, so you will notice it isn’t as stable through the turns. 

If you’re looking to maintain a turn, you’ll need to make an investment to stay upright, adjusting both fore an aft pressure. 

Unlike some wing designs, the Hydros won’t lose speed in a turn – in fact, if you lay into a turn you’ll notice this foil only accelerates.

Traveling with the MFC Hydros

The Hydros comes with a padded foil bag meant to provide a safe place to store your foil. 

This bag is key and can protect your foil for travel as long as you pack it carefully. 

Some riders report packing the wrapped foil within their luggage, surrounding the foil with their clothes and towels to ensure it makes the trip to and from the beach safely.

Another feature that makes the Hydros a good foil for traveling is it’s construction. 

Unlike some performance foils, the Hydros breaks down completely to allow for more compact packing. 

Just grab the hardware kit and tools it came with and you’re good to go on just about any adventure.

MFC Hydros Review: Right for you?

Trying a foil out is the best way to gauge its feel and fit for your style of riding, but that’s not always possible.
