Hump Jumping – It’s hard to “get air” going off a big slanting drop. However, you can use irregularities on the face of the drop (humps, bumps) as mini ski ramps to launch from. When contemplating a hump jump
ALWAYS inspect your launch hump carefully…an upstream-pointing face irregularity can pin you or literally rip the bottom out of your boat (and you)! By studying aeriation (or lack of aeriation) on or near the hump you can make a number of safety oriented decisions.
