This is the B flag for the B course.
Yesterday in a light air race, the old guy was carefully picking out the ares of pressure to work toward on the first beat. He linked up a group of patches leading up to the mark and it looked like the others could not get to it before he did. Good work! We will get to that mark before them. Take another look. They are going around the other windward mark (we have two windward marks to handle major wind shifts). Oh! Oh! I am sailing the wrong course. Ouch!
So now I need to add another note to the "before start list": 1. Check for up wind end of line. 2. Get a range. 3. Time the line. 4. Check for current. 5. CHECK THE COURSE SIGNAL.
