Grubbies

An aerial downwind 360 using the scoop on the front of the board for sliding and rotating the board.  The Grubby is a nickname for Greg Allaway of Australia -- the inventor of this maneuver, who accidentally stuck this move by spinning out on a downwind 360.

This maneuver is best performed in underpowered conditions. The initial challenge is learning to jump the tail around while heading downwind and to avoid the painful pseudo-loop scenerio by training the body to sheet out the sail and lean back agains the sail upon catching the nose of the board on the water. Some sailors have described the maneuver as leaving the sail behind as they jump the tail downwind.

Bear almost dead down wind but not quite.
Spread you hands and try moving them a little back on the booms
perform a quick jump, sheet in, and extend mast hand out
Focus on kicking the tail of the board downwind and extending back leg
Extend the clew arm out and bend the mast arm with sliding backward

The Standard Grubby has three natural variations: The Grubby 540, the Grubby into a Carving 360, and the Grubby Diablo. I have also seen Web Pedrick do amazing one-handed Grubbies.

The switch stance variation is called an ESLIDER which also has the 540, 1-handed, and Diablo variations.
