Look for some chop slightly upwind. On flatter water, head across the wind or slightly off the wind. Unhook and (this is very important) slide the front hand way forward on the boom toward the boom head. Speed is generally your friend so charge like Madd-Maxx into this move. If you're uncomfortable with the speed then head upwind a little to kill the wind.
Crouch your body down while also leaning slightly forward so you can explode off the water. This is an aggressive move so Jump really hard by pushing down with the back foot and lifting the front foot and front arm up to the sky. Remember to jump off your toes like when you jump rope and to keep your body centered and close to the mast. On flat water you will even have to jump harder. Initially Sheet-in the sail on the jump so you have enough power and lift to jump the board around. Your eyes are best focused somewhere near the mast foot.
This is the most important part of the move and must be integrated seemlesssly with the previous step: Pull the heel of the back foot up toward your buttocks so the board is completely out of the water while simultaneously releasing the back hand and swinging the rear shoulder (so you body opens up to the new direction).Look back in the other direction, or, as I prefer, look down at the board to the area just in front of the mast base.
Reach the open hand toward the other side of the boom and pull the mast toward your body, across the wind. Try to make the hand movement super fast. Look in the other direction, or, as I prefer, focus your eyes down and vertical over the water so your body weight is centered properly to land on the front section of the board. You are jumping in a way so your body is positioned over the center of the board.
Grab the other side of the boom with the open hand. Notice your arms will cross here.Kick your legs behind you while leaning your body slightly forward over the nose of the board. Focus your eyes down on the front part of the board deck, just in front of the mast base. Notice my weight is over my front leg and my back leg is extended like a brace with the toes down. Also, the nose of the board is on the water and sliding backward. The nose lands first. Some sailors like to Swivel (twist) the body up and around the mast.
Maintain your body weight over the board by leaning slightly forward over the center of the board and a little on your toes. In other words, your weight is over your front foot. This keeps the board's tail and rails clear of the water, so you can maintain a slide. Your body remains somewhat twisted. Remember to stay close to the mast.
Let go of the trailing hand and lean the mast windward. Your weight is still forward so the tail stays out of the water and the board slides backward because the back rails do not catch the water.
Reach back and grab the boom as fast as you can while still leaning the mast windward. Notice my body stays erect and centered over the board.
Sheet in very hard to lock in the sail and regain the board-body-sail connection. You also must shift your weight windward so you have now regained any lost stability. The key to gaining stability in a Vulcan is to get to this position quickly.
Let the board slide to a stop.
Start sailing switch-stance until you feel like you have control. The trick to sailing switch stance is to keep the body twisted with the sail sheeted-in and your body weight windward. Slowly bear off wind.
Now lean on the front foot a bit and push the heel of your back foot down and out away from the strap. This is tricky to learn at first because the natural tendency is to pull up with the back foot -- not! Switch your feet to a regular stance. Live long and prosper my Vulcan brother.
