Dale is 185, but weight cancels out of the 1/2mv**2 = mh equation, so except when a big guys literally flattens a small ramp (e.g., chop hopping), weight doesn't matter.

Until they land.

"until they land" is the operative phrase.
What goes up, must come down. Going up, Dunks, Albeau, heck, DaveLeahrs (245lbs.) can hit sky shots better than most tykes, but landing, they break. They break their fins, their boards, their booms, their bases, their knees, ankles, hips, wrists.........

5 pages in to this thread and, unless I missed it, no one has talked about timing, compression or pre-jump in the trough? I've got some of my biggest air off of 2-3' chop. You know you hit it right because you feel like you've been shot out of a cannon and get that, "oh sh!t" thought in your head when you leave the top of the lip.

Clearly more analysis and discussion is needed. To wit, Celilo, the jumpers mecca, happened upon by a bored, and wind starved boy from Vancouver, USA.

(thanks Mark for the vid)

From the 1st page:

Pick a line that gives you plenty of power, yet gives you a good angle to launch off the swell... you may need to round up a bit to line up properly, but don't do so to the point you lose a lot power, you'll just crash. As you approach the ramp, unhook. As you hit the ramp, instead of trying to absorb it with your legs, do the opposite, push into it to get a good launch.

Ah there it is! I had to laugh when I saw that we both referenced "Holy Sh!t" and "Oh Sh!t" for that feeling. Very Happy

Thanks for the Celilo clip Dale.

Watch what happens when he hits a gust.

Im getting better in the straps and want to move onto some new things... Time to try some jumping Very Happy Ive messed around with it a little bit but want to get some various tips and suggestions on chop jumping, swell jumping and swell riding in general in the Gorge. Im sure plenty of you guys have some good techniques to share and just suggestions in general on what to do with all those bumps and swells when your cruising on the river Smile
Nice to hear you
ve mastered the footstraps Smile . Get up maximum speed with control and launch!!!!!! Riding swells and rollers are much easier on the body, go get it while your still young!!! Very Happy
