Unhook, flip the sail, and head downwind on an acute beem reach.
Perform the standard chop hop for this genre of moves: a quick hop with the body somewhat vertical and a waist swivel so the tail swings around. Your Vulcan was the training for this skill
Stick the nose in the water with your feet extended so the board can slide the bottom while pulling the mast through the wind to get backwinded. Lean back into the sail so the board will slide on the nose and not catch the back rails.
Keep your weight forward over the nose as you slide backward down wind.
Extend your front arm as the tail catches and the board spins.
Lean slightly back to counterbalance the sail as the clew passes through the eye of the wind and powers up on the other side. Keep pulling the mast around.
Shift your weight over the other rails into the switch stance position. You body will follow your head.
Sheet out to depower the momentum so you can stabilize the rig in a switch stance position.
