Surf ski normally uses low bracing. However, there have been times that using it just dont quite save you from getting a dip. 

Here's a link to high bracing drills.  http://www.seakayakermag.com/2005/Feb05/highbracing5.htm 

Can you guys comment if this is applicable to Surf Ski? I assume its best to leave your foot in the straps while attempting to high brace and rotate.

Just be aware that if you're going to dislocate a shoulder it'll usually be while doing a high brace! Bear this in mind when paddling a long way from the shore.

Thanks for the tip Shaun.  I did however dislocate my shoulder one time from doing a low brace.  But the wave came from an outgoing Catamaran and the force was just too great. I was on an icf k1 back then. 

Can you guys post me a picture of how a high brace looks like? I just want to confirm if what Im doing is right.

The low brace, done with knuckles down, "punching the water,"  varies in effectiveness with a wing paddle.  With a right feather, it is easier to low brace on the left, and high brace, "palms up," on the right. When you watch video of someone surfing, they may skid their paddle along out to the side for stability. This works well on the non- power face, knuckles down. If you are stopped and wallowing, the low brace on the non-power side with a wing, tends to sink more than with a flat paddle. Not only that, but it is difficult to pull back up, as then the scooped power face grabs as it is designed to do. If you are in this situation with the left blade submerged, jerk the paddle to the right in line with the shaft to exit the blade.
