the moreon twins looped in their first week (apparently.....)
everyone knows windsurfing is all about practice, and lots of it. so talent combined with a lot of practice is the key. there is a reason most of the UK pros have spent a lot of time abroad... its pretty difficult to get enough time on the water in the uk compared with 8 hours and day in some places. although at the moment in the UK this might not be true??
in terms of sponsorship its a bit of a misconception that its all down to rider skill, although this plays a big part what most sponsors a looking for are ambassadors. people who are fully involved in the sport, get a lot of coverage, go to events, write articles make videos etc etc. potentially you someone could be a sponsored beginner board rider promoting starboard gos and be crap at windsurfing....
likewise there are loads of kids who sail to a high level in remote desitinations around the world who struggle to find sponsors becuase its hard for them to promote products
