In like new condition. This sail needs an RDM mast which is why it's being sold as a package.
The Hydra Pro is a light-weight, low-drag sail designed for high-speed freeride foiling. The Hydra Pro excels in the extreme upwind and downwind angles that make free-ride foiling so much fun.
The unique foot of the Hydra Pro reduces the unwanted turbulent airflow that occurs below the foot of a traditional sail. This extended foot gives the Hydra Pro a smooth and predictable feel when foiling.
To match the higher speeds and forward apparent wind angle that a foil generates, the new Hydra Pro has a flatter, more defined profile. Flatter allows the Hydra Pro to go faster and achieve tighter apparent wind angles.
With approximately a 15 cm range of outhaul tuning, each size of Hydra Pro spans a large wind range, meaning fewer sails are needed in your quiver.
The Hydra Pro is a dramatic look for a dramatic new form of windsurfing.
WHAT IS DIFFERENT IN A FOIL SAIL? FOILING V.S. NORMAL WINDSURFING
First off, 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. And third, your board is above the surface of the water when you’re flying on the foil.
EXTENDED FOOT BATTEN
The elongated foot on the Hydra Pro takes advantage of the board’s height off the water to create a hyper efficient sail. On a normal windsurfing sail, a long foot like this would hit the water when cruising and simply not work, but when foiling, we can take advantage of this “free” space created by flying above the water. The extra long foot forms an end-plate with the board. This is very similar to how winglets work on a jet wing, and aerodynamic theory tells us that an end-plate like this greatly improves the efficiency of the sail.
The extra long foot provides the needed low-end power to get up on the foil without using cambers or an extra batten below the boom, 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. You want a sail that “goes away.”
The extra long foot 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. But at the same time, because only the foot is extended and not the entire sail, the pull of the sail remains forward for a more comfortable sailing experience.
NEW BOOM CUTOUT
Instead of a traditional boom cut-out, the new Hydra Pro features a cut-out that consists of multiple short compartments, which reduces sail distortion caused when the mast bends. This makes the sail more stable when powered.
