When the call is made to jibe, I stand up, go forward, and as the boat starts to go through the wind, help the kite through the jibe by pulling aft and down. How hard and fast you need to pull is determined by the wind strength; slow and controlled in the light stuff, fast and furious in the breeze. Kite size also makes a difference because larger kites require more strength in the breeze. On a J/120, with its massive spinnaker, we've found that in more than 18 knots, the outside jibe is much easier than muscling the entire thing through an inside jibe. With either jibe, the rate at which the trimmer tails can make or break a good jibe. The trimmer should be tailing the sheet for all he's worth. The second trimmer simply eases the old sheet, and once the clew is past the headstay, lets the sheet run free (making sure he's not standing on the tail).
