Thanks to Simon for a good call and thanks for the GPS.
Thanks Johnny for the sd card and for sorting the data.
Brilliant sail on the screamer what a lovely board. Forgot how lovely. 31k ave and 34.2k 2sec and comfortable all day long plus a 4k v max on the missile :-) just for comparison :-) 40k screamer is it possible ?? 40k jim on a screamer !!! is it the future of Cornish speed sailing :-) Well done to everyone else good day all round.
