Chris:

It is not sheeting it is the traveller. Here is the deal, as good as you can gybe you will not be able to keep ALL the boat speed through to the new direction. You will slow down a bit. By travelling out you will keep the sails from stalling for the initial couple of seconds. As you get back up to speed, travel in. It all happens so quickly you may wonder about the advantage, but think about the speeds of these boats. Two seconds stalling a sail is about 3 boat lengths in wind. How many races have you lost or won by three boat lengths? That is for one gybe, now multiply by the number of gybes you perform in a race. This also aids in getting the hull out of the water, like a big birds wing on takeoff. Hopefully you will be travelling the main in at the same time the spinnaker is getting in and there will be the GREAT GYBE feeling!

This may not be exactly right for everyone. I have tried it several ways and settled into this one. It gives me the most consistant results in a gybe.
