Had a great time on the Formula again today and good that Jonny Turned up for a sail too. Sadly there was not enough wind for my Father and Simon as they only had Medium Slalom boards. Wind was ok and a few patches of sun in places. Jonny did comment on the shape of the sail and this confirmed that the rig certainly needs something to work better, since it was all out of shape heading downwind. Only managed to get the board really loose once and pleased to get over 27knot 10sec. Plenty more to come from this set and certainly on the right day a 28knot av ahould be obtainable. Session ended badly with me jumping off the board right at the end, getting one foot stuck in the strap and my knee making an ominous popping sound. Don't really want to go to hospital but will see how it is in the morning :-(
