not a good USM for me , did  not sail this spot for 3 years and lost my tuning . Took me about 3 hours to get sorted on the tuning and smacked my fin into a rock . So had to go back to the beach and missed the best gusts of the day . did get 3 gusts in the last 2 hours of the period when i found my tuning but it was to late and the wind dropped so no more runs . Better luck next time
