Arrived at 9 am after driving down from swindon, looked good with white caps accross the harbour.  Decided on 6.2 and 94L JP slalom, but after two runs the wind dropped down to 20 knots and struggled to get going. At about 1 O'clock the wind freshened and the speed starting going up to 32knots. the session was cut short as my son Will  span out at 33 knots and twisted his ankle. Mark (Swagger) was near him and helped him, as he was dazzed. Thanks Swagger. We packed up and went back to Swindon A&E, fortunately the x ray  didnot show any break, so he'll be hoping around for a couple weeks before getting back on the water.
