Disclaimer:
Please Note, during the lengthy production runs of the A27 (8.2) and A28 (8.5), Ouyang Boatworks used a number of different mast and sail suppliers and specifications with differing mast and boom lengths. We are not aware of similar variations in the A30 and A32 models, but it is always possible. With this in mind, please do not rely on the measurements provided if you have to pass under an overhead obstruction (eg bridge or powerlines) where clearance will be limited, when ordering sails or establishing a racing handicap. If you require accurate numbers for any of these purposes we strongly recommend you measure your actual boat and we accept no responsibility for the consequences of any inaccuracies in the quoted figures, or in variations applying to your boat.
