Lightweight and stable, the Hydra is perfect for foiling. Sheet in and the Hydra generates the right amount of power to fly the foil. Sheet out and the Hydra's power gently subsides, lowering the height of the foil to reduce foil-outs. These smooth power transitions are a result of the Hydra's unique 3/4 batten above the boom. Because the batten stops short of the mast, the Hydra's deep forward shape "goes away" (luffs) when the sail is sheeted out.

We designed the Hydra to have a low foot in order to reduce unwanted turbulence that occurs between the board and the foot of the sail, making the Hydra more stable and easier to foil on than a sail with a higher foot, like a wave sail.

The Hydra's foot is not so low that it gets in the way while doing traditional freeride and bump-n-jump.

The large, Dyneema-reinforced X-ply window allows excellent visibility, which is critical for making foil jibes. The main body of the Hydra is built with reinforced scrim.

Like all of our sails, we rig, check, and calibrate each Hydra Sport in our factory.

The Hydra is a great choice for anyone wanting a lightweight and balanced foiling sail that can also be used for regular windsurfing.

WHY CHOOSE THE HYDRA?

The Hydra is a foiling sail that works on a traditional freeride board.

Because the foil can fly through the water with so little drag, the wind angles are different, which means that the apparent wind (the wind created by your movement) shifts forward. Second, you need a powerful sail to pump up onto the foil, but once you’re on the foil, you want a very easy to control, light sail.

FOOT AREA

The foot panel on the Hydra is large enough to be efficient and get quickly up on the foil in light winds but not so large as to interfere when freeriding on a fin.

The extra foot area provides the needed low-end power to get up on the foil without using cambers, saving close to a kilo in weight. Being able to ride a smaller, lightweight sail makes foiling more fun by giving you the sensation of flying with nothing in your hands.

Foot area also makes the sail more stable. This means that you are less vulnerable to gusts throwing you off balance when you’re flying on the foil, which makes foiling a lot easier. By keeping the sail's area low, the pull of the sail remains forward for a more comfortable sailing experience.

3/4 BATTEN

The Hydra borrows the 3/4 batten concept from our hardcore wave sail, the Taka. A 3/4 batten allows the sail to luff, which means that it can easily go from full to flat. This is important for many aspects of foiling. This helps the Hydra to be extra powerful when you’re pumping it but flat and responsive when flying on the foil. And, the Hydra’s 3/4 batten is the reason it can de-power so easily and change its shape for the needs of the foil. When you sail up wind, you want a flat sail, and when you sail downwind, you want a full sail. The 3/4 batten allows both to occur without having to adjust the outhaul.

The depowering also makes transitions easier when freeriding on a traditional fin.
