People need to be reminded not to park on the finish line, though...
Yes... that turns out to be tough to remember to remind the fleet at the skippers meeting.... Instantly clear to the PRO on the water after the fact.
(assuming no wild course changes are needed)
John Macilag, the PRO, handled the 30 degree shifts this way. All starts were independent.... no rolling the start sequence. Big wind shift on the course but the 16's and 18's were still rounding A mark and you could not move it. Rather then wait and hold up the 17's who were ready to go again.
He flew the gather round the boat flag for the Hobie 17's. He then flew change of course flag and notified the fleet that they were now on the change mark... which was yellow. and we posted the new change mark heading on the compass board.
He then started and finished the 17 sequence. No flags on the RC boat. Meanwhile, He then had the pin boat relocate the pink A mark inside the now dropped Yellow mark. The 16's and 18's continued to sail around Pink all weekend. It was just relocated prior to their starts. It certainly kept things moving and everyone sailed to their proper mark.
First time I have seen it done this way and it worked well.
