I will be away for a while so before I go here is the critique of Alice's gybing style taking specific frames one by one.
At second 48 Alice begins her carve. Her knees are pointed into the turn and are in front of her heels. Her hips are forward of her knees and shoulders in front of hips. The board is nicely banked.
At second 50 she has swivelled her hips to turn the body and has stepped, keeping the weight bearing on the inside of the turn and forward on the board. All good
At 51 she is looking out of the turn (good) and at 52 she flips the sail but allows the front hand to slide up to the mast as the sail is flipping. This is not good as she cannot maintain mast foot pressure doing this. Her hand should have been placed onto the boom by the mast earlier and downward pressure resumed simultaneously
At 53 she looks at her hands. Not good. She should continue looking out of the gybe.
At 1.01 (another gybe) she has banked the board nicely and at 1.02 she is looking through the window to where she is going. At 1.03 she has flared the sail and is flipping, keeping her weight inside the turn but then the tail of the board sinks because she is leaning back a bit and not pulling down on the boom properly. If she had been going a bit slower this could have stalled the move.
At 1.04 she recovers the situation by stepping forward pushing the board back onto the water. Good
She flips the sail and looks at her hands once again. Not good
At 1.23 she is looking through the window at where she is going. Good
Her front arm is reasonably straight and she is pulling the rig over for the flare. Good
At 1.24 she flares but is not leaning forward enough. She pulls the rig towards herself.
At 1.25 the nose of the board lifts but luckily she has the speed to keep planing.
At 1.27 she steps nicely and has now brought her weight forward and to the inside of the turn. The board is level once again and she looks out of the gybe. All good
At 1.32 she flips the sail but looks at the rig again as the sail comes round. This causes her to lean back a bit sinking the tail of the board.
At 1.40 (another gybe) she has flared the sail and is stepping. She pulls down nicely on the boom.
At 1.41 she is flipping having placed her front hand on the boom maintaining mast foot pressure. She looks forward out of the gybe. Well done
At 1.49 she is looking out of the gybe, has stepped and her backside is hanging out on the new side to maintain pressure on the inside rail. All good
At 1.50 she flips but once again looks at her hands (this is just a habit I think).
At 1.57 she exits a gybe looking forward. Her backside is well out over the edge on the new tack to counter the force of the rig as it powers up. This also allows her to pump the sail if required
Thats all for now. I hope you manage to download Alice's video and examine the above frames. Quite interesting.
Talk to you soon. Stay sheeted in
