This is all about angles. A rig is easiest to control clew first off the wind. The earlier we open the rig the more violent the flip will be. Getting this right is often about patience in the midpoint.
• Wait until the board is pointing off the wind on a new broad reach, then the next part happen at once.
• Throw the head from one shoulder to the other, to oppose the rig.
• Shift your weight back as you slice the rig over the nose to clew first.
• As you do this switch your feet, bringing the front foot to the back foot and throwing your weight to the inside as you complete the switch.
• You should now be able to hold this clew first until you decide to flip.
