“Points of sail” describes a sailboat’s course in relation to the wind direction:
A: Into the wind -- Sailing as close toward the wind as possible without having the sails flap (“luffing”).
B: Close-hauled -- Any sailing direction between the beam reach and the close-hauled where the wind is still blowing from ahead.
C: Beam reach -- Sailing at a 90-degree angle from the wind; the wind is blowing from the side (“abeam”).
D: Broad reach -- Any sailing direction between the beam reach and the run where the wind is blowing more from behind (“astern”).
E: Running -- Sailing with the wind pushing from astern.
