Mast – the main and highest spar in the center of the boat.  The mainsail and jib are attached to this.

Boom – the horizontal pole or spar that extends back, or aft off the bottom of the mast, where the foot of the mainsail is hooked.

Standing rigging – supports the mast.

A.  halyard – line used to raise the sail and control luff tension.  main halyard & jib halyard.

B.  sheet – main line that is used to adjust the sail against the force of the wind.  The mainsail has one sheet.  The jib has two sheets; a working  or leeward sheet and a lazy or windward sheet.  Angle of attack with respect to the apparent wind and/or the amount of leech “twist” near the head of the sail.

C.  boom vang – line that places leech or downward tension on the boom.

D.  outhaul – puts backward tension on the clew of the mainsail.  When tightened it flattens the lower one-third of the mainsail.

E.  reefing line – a line used to shorten the sail.

F.  cunninghams – tighten the luff of a boom-footed sail by pulling downward at the point on the boom closest to the mast.

G.  guys – control spar angle with respect to the apparent wind.
