Basics seem to be...

Weight moves forward during tack. The crew has to hold the jib (backwinded) by hand and can let it fly on a moments notice as the boat may begin to back rapidly due to wave action and gusts. The rudders have to be reversed to back the boat around to the new tack. Main very loose. Jib re-sheeted to new tack as main begins to come in slowly get boat moving before sheeting main harder.
