Race Marks & Courses
The following information is from the 2026 Racing Handbook, Part IV,
Marks and Courses (Pg. 29)
IV-A Courses
Color coded placards will be displayed on the Race Committee (RC) boat for each mark (buoy) 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 (in relation to the boat), and green if the mark is to be left to starboard.
Example 1: KLAK 2
Start between the RC boat and the K mark, passing marks K, then L, then A, then back to finish at K, passing all marks to port, and go around the course twice.
Example 2: KLAK 2
In this example, you would follow the same course, only you would round the A mark leaving it on your starboard side.
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.
Example 1:
SP A A L I A 2
SP B A L I A
SP C A K H A 2
Example 2:
SP A / SP B A L H A 2
SP C A L H A
