The ‘Storm’ has set the benchmark for all-round performance in high winds and chop since Tushingham were the first to recognise that not all high wind sailors were wave sailors.

The Storm Force 10 represents a major upgrade for 2009 . Ken Black’s design brief was to retain the forgiving nature, yet deliver a lighter, crisper feel in transitions, whether in a simple gybe, on a wave face or through the latest new-school freestyle trick. The actual character of the sail varies with size:-

6.0m – 6.5m - The larger Storm F10’s are now oriented towards earlier planing, crisp power delivery and easy manoeuvring. Speed and straight-line performance remain, but those seeking ultimate no-cam freeride speed are well served by the Thunderbird in these sizes. Lessons learned when developing the Wedge (freestyle sail) have introduced subtle adjustments in outline, seam shape and luff curve to increase low end power and to deliver a particularly light feel in transitions.


4.75m – 5.75m - The mid range sizes are the true Storm all-rounders, they have to work in all sea and wind states from flat and marginal through to rough and gusty. These sizes are often used as a ‘small’ sail on larger freeride hulls or a ‘large’ sail on wave crossover boards. It’s crucial that the power delivery is adaptable for both locked-in freeride sailing and a more upright manoeuvre oriented stance. The tuning range has been maximised so that the sails will work in virtually any windsurfing environment.

3.5m – 4.5m - When you’re using a sail this small, the water and wind conditions demand a sail that’s cut for ultimate control. Whilst the reasonably high foot and easy rotation keep the Storm F10 out of trouble in waves; the ‘Rock’ (wave sail) has the leading role when it comes to manoeuvre based sailing. Consequently, in these sizes the Storm F10 is cut with a twist profile that will hold the board on the water in gusts. A ‘locked in’ feel is achieved by retaining reasonable boom lengths and shaping the power in low down which, makes high-wind freeride a pleasure; even in choppy or rough water.
