Just thinking of how people on this board might be interested in transferring their snowboarding skills into another summer boardsport. This summer I started to longboard, and also got more serious about kiteboarding. It's been fascinating seeing how these sports relate (or don't relate) to each other.
I've found that longboarding downhill is really similar to snowboarding. It seems that the same 5 skills from snowboarding (stance&balance, edging, pivoting, pressure control, timing&coordination) continue to be relevant to longboarding, although to different degrees. Also, it's probably fair to say that snowboarders will have a quick learning progression on a longboard. Here's an example of longboarding slalom turns:
In contrast, while learning to kiteboard, I've felt almost no benefit from being a snowboarder. It's like a French+Spanish speaker trying to learn Japanese: some of the parts exist between the two, but the structure is competely different and some of your existing knowledge can actually create roadblocks. While the same skills from snowboarding continue to exist in kiteboarding, their application is significantly different. E.g. if you kiteboard with a snowboarding stance, you are going into the drink! I get the impression that wakeboarding is much more similar to kiteboarding.
Does anyone else have other boardsports experiences, similar or different?
