If you ever wondered just how hard a jetski can corner. I set up my 3 axis accelerometer and wrote software to do the filtering. This was written to get a way to analyze motorcycles on a track. It maxes out at 2.25 geez in smooth water. Accel maxes out at .8 geez out of the hole. This happens to be a 2000 XPL with vertical plate sponsons.

Top Graph is what is known as the friction circle in the car racing world
Horizontal geez compared to gas/brake

Center Graph:
Lt Blue Unfiltered vertical load
Black Filtered vertical load
Dark Blue Acceleration
Gold Horizontal Load
Red Total true horizontal geez

Bottom graph:
Black Lean angle of the ski
Pink Overall lean angle of bike and rider
Gold Rider hanging off angle for lack of a better name
