Course diagrams

Clear communication is important to give sailors the best experience and many will rely on simple, easy to understand course diagrams.

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
