chine walk

its something that ive never really experienced though. ive been in 95mph in v-hulls, 135mph in cats and they will bounce from chine to chine, but still track straight. this gets squirrely going left to right, progressively more each time, and if you dont let off, it feels like the boat will dart to 1 direction, which would be very bad. i dont mind a little teeter from chine to chine, but the left to right stuff is scary...
