Mainsail

A5Mi

Alien has kept the girth on most boat types, but has a different sail shaping concept, different corner construction, and an all new DS part to give you better shape control. The result is much better acceleration and higher speed. An even more versatile sail that gives power to light things and can release power when you pick it up. The special pentex reinforcements for the leech around the clew area help to control the leech at a higher level.

Even the appearance of the sail has been updated.

It comes with a rocket tensioning system with new, upgraded battens.

Jib

We made two jibs with two different features.

A5JP

Easier to handle jib, fits perfectly with the A5Mi. It gives perfect flow to the mainsail with a more variable twist that helps a non-pro sailor not kill the flow between the two sails and find the sweet spot much easier. We have also achieved for those who like to sail at a lower angle and seek upwind speed to generate amazing speeds and VMG numbers. This sail is a multi-round sail without being too full on top above 25+kt, but still has amazingly low end power.

A5JC

The A5JC is a conventional jib with a larger back draft position, similar to pro and premium line sails, and it’s for sailors who like to sail upwind, in a more traditional style, pointing high

Gennaker

A5K

The A5k kite is the ultimate downwind weapon. The Alien gennaker is only available in polyester material, much more stable, higher performance with light sheeting load. The shape of the sail can easily change between strong and weak wind mode, it is easy to find the right places.

Due to its material, the sail requires extra care on land in order to maximize its lifespan.

The set of Alien sails fully proved its capabilities in Clearwater, even without a World Champion title.

Alien sails are only available as a complete set as they work perfectly together. We can even customize the shape of the sail based on personal preferences.
