Here's a picture series from a boom cam video where Andy demonstrates the push tack in light winds: Start sailing switch stance. Note that the front foot is pointing forward.
The first part of the sail move is done only with the mast hand, so let go of the clew hand.
Push the sail towards the back of the board with the mast hand.
On a big board like here, the front foot steps before the mast. On small boards, the front foot can remain behind the mast.
When the sail is all the way back, switch hands: grab the boom with the clew hand, and let go of the mast hand.
Push the sail further back with the clew hand. The sail remains neutral, so the mast will swing to the leeward side.
When the sail is all the way back, push gently with the mast hand.
Look forward and keep pushing with the mast hand. You are backwinded, so you heels are on the center line, and the windward rail is dug in by putting pressure on the toes.
Almost done with the turn.
Stabilize and sail away clew first.
Or, use the short version:
Push with the mast hand.
Push with the clew hand.
Push with the mast hand.
Pushing with just one hand is the key (just like in the heli tack). If you push with both hands, chances are pretty good that the sail with load up with power and throw you off.
Here's the video that the pictures were taken from:
Here is a video from Andy's lecture about (light-wind) downwind 360s, aptly named "pile drivers". The lecture explains the easiest one, the clew-first pie driver.
I uploaded two movies from Andy's body drag lecture in Hatteras, October 2010. The first movie is a pre-exercise that teaches how to get back onto the board:
Andy teaches the getting back on by curling both legs to your chest. The Tricktionary describes a slightly different technique, where the back foot goes onto the board first. I think it's a bit easier the Tricktionary way, but you can do the pre-exercise either way, so judge for yourself.
Here's the part of the lecture that describes the whole body drag:
If you are taking an ABK camp, you should not try to learn the body drag on the first or second day of camp! This move can be really hard on your arms and hands, since you'll be hanging most of your body weight off the boom.
Below is a video from a duck upwind 360 lecture at the ABK camp in Hatteras, October 2010. The duck version of the upwind 360 is actually the easiest version of the upwind 360s.
Here's a question for the really advanced trick surfers: since the duck version of the upwind 360 is easier than the regular version, and the Flaka is basically a pop-and-slide upwind 360, it would seem logical that the Flaka Diabolo (a Flaka with a sail duck at the end) should be easier than a regular Flaka. Is that so?
