Wally and Omer Wing Sail introduce the WOW Sail, the wing sail technology for cruising yachts that offers unprecedented advantages: high performance in terms of boat speed and heading angles; ease of handling by one person only, whatever its dimension is; lowering and reefing characteristics; reducing and simplifying the boat structures thus improving the interiors; simple, safe and reliable.
The WOW Sail system is simple:  it includes a free-standing, rotating carbon fibre mast with carbon fibre frames that hold the fully battened 3DL sail cloth, and is manoeuvred by a hydraulic ram with push button control to change the profile of the wing, and by a sheet to trim the sail.

The WOW Sail increases the performance by 10-30 per cent in any condition, depending on the displacement of the yacht: the lighter the boat is, the more efficient the wing sail is.

The high performance is combined with easy sailing characteristics: one person can handle the huge wing of a yacht like the Wally 130.
The WOW Sail keeps its shape longer, and it lasts longer than traditional sails because it never slams.
