Course diagrams and flags

Clear communication is important to give sailors the best experience and many will rely on simple, easy to understand course diagrams. These should give you a good idea of the ingredients needed for happy sailors.
 

World Sailing uses a system of assigning symbols to courses (course signals) which consist of letters and numbers. The number always relates to the number of beats that a competitor is to sail to complete that course.

Course designations

  • L - windward/leeward course with a leeward finish
  • I - an inner loop trapezoid
  • O - an outer loop trapezoid

  • M - a windward / leeward with a leeward finish with starboard mark roundings ( commonly used for match racing)

  • A - course with an offset mark at the windward end

  • R - course with a reaching finish at the leeward end

  • X - course with non-standard finish

So an LRA2 course would be a windward / leeward course with an offset mark at the windward end and a reaching finish with two windward legs

Flags are useful for teaching, creating timekeeping sheets and writing sailing instructions for children, youths and some club racing.
