in my ho, the group of four boats about to round are screwed. the inside boat with rights is so close to the mark that it will carry the other three in her group wide during the rounding. the 'last boat' appears to have an inside overlap on the boat to her outside. a gybe by the outside boat looks risky, she needs to give the 'last boat' room and opportunity to keep clear. looks to me that the 'last boat' should be able to do a 'seamanlike rounding' and come away from the mark well to windward of the other boats (not including the first two) and at least pick up some positions...whaddya think?
