The original boats had sails made by the owners preferred sailmakers, so they were all different. The Dashew specified main was 74m² and the job was 45m². I will try and dig out the original rug dimensions, though they made the mast in three sizes, and had various foreteiangle arrangements. The boats were more a semi-custom than a full production boat, so there are small differences between all of them.
And to be clear: the Sundeer 56 rig is exactly the same as the 60, as is everything except a 0.9 mlengthening of the hull at the aft end in the 60.
