|Since there appears to be online interest, here are a few more tidbits from article:
"Since these boats (C&C 27, Catalina 27, Ericson 27) are designed to show a good turn of speed around a racecourse, it's worth looking at the performance ratios. In terms of displacement/length (D/L) ratio, which measures the relative weight of the boat, the C&C at 265 and the Catalina at 297 have a distinct edge over the Ericson at a fairly high 342. For acceleration in a puff or out of a tack, the C&C would have the edge over the other two.
The C&C also has an advantage with its high sail area/displacement ratio (SA/D) of 17.6 compared the Catalina's 15.3. Even though their sail areas are almost equal, the Catalina's heavier displacement (by more than a 1,000 pounds) is a distinct disadvantage, especially in light air."
The author, Rob Mazza, used to work at C&C. I'm sure that does not bias his view in favor of C&C. He is just smart.
