The Skull is our radical 4 batten wave sail from the XO sails range.
With its 4-batten shape, the Skull is ultra-light in the arms and offers exceptional handling with perfect balance in the hands, even in the biggest gusts. It is a sail that will adapt to all conditions, from side-shore with powerful hollow waves to more imperfect on-shore conditions with less propulsive waves.

With a trough positioned in the front of the sail, it will deliver the power you need when you need it, but also cut it off in a fraction of a second.

With the use of Pentex at the head of the sail and work done on the outline and materials of the other panels, the Skull 2022 offers rock solid strength while bringing a gain in flexibility and range of use, with notably increased control in the high range of use.

The Skull remains the perfect sail for side-shore conditions. We recommend the use of an 80% carbon mast for the lighter sizes. By using a 100% carbon mast, the sail becomes more powerful, making it perfect for heavier sizes or side/on-shore conditions.

With its reduced boom length, the Skull will allow you to lengthen your bottom-turn while maintaining perfect control of your board, even in the most difficult conditions.

  5. #TEAM ADVICE#The SKUL is an excellent side shore wave sail.

    The recommended mast for light sailors will be 80% carbon.

    With a 100% carbon you will get more leach tension and draft locked forward, in this option the sail will offer better planning ability and more control for heavier sailors.
