The race committee (thanks Nabeel and Francisco) smartly kept the marks in place for the second race but renamed the marks from leeward to windward, and windward to leeward, so you might call that a shifty day. In the second race i started on port on the right end of the line while the fleet sailed on starboard on the left end of the line, and in a very light wind once around the course, maintained a lead and won. On such a light shifty day the key for me to keeping the boat moving was watching the windward boats for indications of possible shifts, and sometimes powering up by bearing off on short term headers instead of tacking.
