At long last, and after much work on Graeme Harbour's Measuring side, and Paul Larsen's Technical Committee side, we finally have a full set of 'A' Class rules in one official World Sailing document. In addition, there is now a revised set of Measurers Guidelines that will now cover and record such things as foil size/position for Classic as well as Open division boats. Also, there is now a new Classic Hull measurement form with the foil radii, draught and tip separation to be noted on all newly measured boats.
Please read these documents to avoid any potential dispute. The claim of 'Well, I didn't know it had all changed!' is not admissable now as we are no longer in a 'trial period' any more....
The full list of measurement downloads, official association measurers forms and guides is on our new Class Rules section here.
