So my 12 year old son is a beginner B2 3 event skier. I have really only ever been a rec skier, but I have been pulling him for jump on our public lake (which actually has a ramp). We are moving his training to a private lake setting and I need to get serious about jump paths. He attended Bennetts this summer and we were told his current jump parameters are RTB-C, "in-course narrow," but honestly I have no idea what that means for the boat path. I understand the ZO settings.
I have looked far and wide for information about various jump paths for the boat, but I haven't found much. Does anyone have a resource to help me understand the various paths, or widths from the ramp? Collegiate split, in-course, in-course narrow vs wide, etc?
