I have recently acquired a '99 TR-21 and I put my '02 Honda on it with a 6" jackplate. My WOT is at 63 medium load. So far I have only encountered minimal Chine Walk at 62 mph so I don't think I have to really worry about it. My question is this about the Chine Walk- I have looked at the bottom of the hull and notice a flat "pad" that starts just forward of the center of the boat on the keel and extends to the back. This is a FLAT pad. It would seem that the boat would be stable on this flat surface vs. a conventional Keel extending all the way to the back. I would assume that chine walking would be MORE with a keel boat than a Triton with the flat pad. Just curious if the other Triton models have this flat pad or is it just my TR-21 and maybe that is why I am NOT getting any Chine Walk OR maybe my Tug Boat speed is not fast enough for Chine Walking?
