Points of sail are one of the most important aspects of sailing. They help to direct and steer the boat by working with the dirsectio and strength of the wind. The points of sail refer to the position of your main sail, as well as the jib. No sailboat can sail directly into the wind; attempting to do so leads to the sails luffing. There are 5 main points of sail. In order from the edge of the no-go zone to directly downwind they are:
Close Hauled often about 45° to the apparent wind - the least angle that the boat and its rig can manage
Close Reach between close hauled and a beam reach
Beam Reach 90° to the apparent wind
Broad Reach between a beam reach and running
Running close to directly downwind
