I am not sure how much useful ''performance comparison'' data there is in those numbers, but the statistics are interesting. The thing that caught my eye was the significantly wider beam, weight and the minimally longer waterline of the 35 and the negative impact of that weight on the SA/D and on the L/D.
The missing numbers here are the ballast to weight ratios, proportions of the sail area in the main to headsails, and draft. Boats of the IOR period often had comparatively little sail area in their standing sailplans but carried most of their sail area in their headsails allowing huge genoas and spinnakers. In other words, as normally sailed the 35 may actually have a lot more sail area and the ability to carry it, making the SA/D less significant.
