Can someone explain to me the differences between these 2 boats? From what I can see, they are identical in dimensions (Length, Beam, Ballast, Disc., SA, PHRF, etc.). The interior
lay out and tankage appears to be the same. Was the change just a name designation change, or is there an actual difference in the boats? I looked on the Tartan owners website, but there's not a lot of info on the 3100.
