Hi Nelle,
Guy Cribb international man of mystery, 13 times British champion, and one of the better international coaches going around is returning yet again to Inverloch in January 2017. Would be ideal for your skill level. PM me if you are interested. If not, join Inverloch Windsurfing Club and join in our training days. The club has a number of RYA accredited windsurf coaches.
