Thanks so much for this info! Seat time is what I need before doing what I did last time out. Boat was stable on water like glass but have never ridden in an 80+ (gps) boat before like the one I have now. I only held it there for a few moments before easing off the throttle. No oscillation/chine walk I just became a chicken! LoL! Glad for this well thought out post. At least I'll know what it is and what to do if it happens. 45-59 is fast enough until I get more seat time in her. :cheers:
