Courses

All marks are rounding marks except those in a box, which are passing marks. Red marks are rounded or passed to port, green to starboard. Select a course to draw it on the chart: its legs are numbered in sailing order, a leg sailed again is drawn beside the first, and a ring shows the side each mark is left on.
