IV-A Courses


Color coded placards will be displayed on the Committee boat for each mark to be rounded, beginning with the starting line and ending with the number of laps to be raced (if greater than 1). The placards will be red if the mark is to be left to port and green if the mark is to be left to starboard.

IV-B Multiple Courses


In the event two or more courses are to be used, a placard indicating individual classes will precede each of the posted courses.
