Re: [Paddlewise] Outside vs. Inside Edge for Turning in Surf

I've stayed out of this, mainly because guys like Duane and Doug have tons 
more experience surfing waves than I do.

I gotta say, though, that Doug's first sentence makes no sense to me.  His 
description of what he does when surfing a standing wave (second sentence) 
makes perfect sense, however.

[What Doug said:

Getting back to Duane's question:  When surfing a wave breaking in a surf 
zone, orbital motion takes a back seat to gravity and waveslope, I think, 
complicated by the fact the water mass of a breaking wave is moving toward 
the beach (I think).  Surfing a standing wave is a somewhat different 
kettle of fish, from the point of view of motion of the water mass (I think).

My bet is that Duane is both skidding _and_ carving, depending on the 
steepness of the waveface, and that when "down wave edging" he is tipped so 
far down-wave he thinks he is using the down-wave edge to carve, but he is 
really skidding. (I think)

If it seems I am hedging here, that's good.  I am so far past my 
board-surfing days and such an infrequent kayak-surfer, I do not have much 
competence to stand on.  But, maybe some of this will give Duane grist for 
sorting out the dynamics.  Doug, he's got more grist than any seven people 
I know, so he does not need any more from me.
