I dont agree with that, if you get to the mark on the port layline you can tack and go straight onto the reach or run. If you underlay while on port tack to arrive outside the two boat length zone you have at least two boat lengths of slow sailing as you build speed out of the tack.
The trick is to find a gap in the traffic <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
