Depends on how much of a stickler you are. The 8700 is(full sized as built) 6" longer, 6" wider and has a 10" deeper picklefork depth than the 8710. The 8700 has a 15" shorter afterplane meaning the 8710 has smaller sponsons. The tunnel width and hull depth are the same.
With that said, the 8700 had the sponsons changed to Jones types in 1989. This shortened the hull by 10", making it shorter than the 8710 by a few inches but the sponson change added an additional inch to the 8700's width. The picklefork depth was also decreased by 10" by the sponson change, making it still 2" deeper than the 8710. This changed in 1993 when the 8710 had the picklefork depth increased by a full foot and, in doing so, gave the hull a 10" deeper picklefork depth than the 8700.
