by the way, this isn't new, it is the safest way of jibing ANYTIME, as the centring of the boom ensures no crew has a "booming" headache, as the boom is moved slowly, also avoiding any shock loading on the sheet. ( this can also be made by a tight sheet, and crossing centreline by use of the track car, if monitored by ropes, so that is controlled, by the resistance of the rope on a winch); in either method the crew ALWAYS knows where the boom is, and any accident is less likely, or at least only a light tap. BUT anytime this is done, the words "GYBING" should be yelled, so any crew knows the boom is about to move!
