Also known as a 'Spinnaker Boom'. The spinnaker pole is a lightweight aluminium tube about 2.5m long, one end of it is attached to a ring on the forward edge of the mast, the other to a corner of the spinnaker. It is used to control and add stability to the spinnaker, and allows the foot of the sail to be held open. The spinnaker pole is normally stowed alongside the boom when not in use.
A spar used to help control a spinnaker or other headsail.
a structure which is used for the purpose of supporting the tack of the spinnaker in a substantially horizontal manner away from the mast
A pole that is attached to the lower front of the mast to hold one corner of a spinnaker out from the yacht. On high-performance yachts, spinnaker poles are usually made of strong but lightweight carbon fiber composite material. When a spinnaker is not being flown, the pole is tethered to the deck.
Sometimes called a spinnaker boom. A pole used to extend the foot of the spinnaker beyond the edge of the boat, and to secure the corner of the sail.
A pole used to extend the spinnaker away from the boat
A spinnaker pole is a spar used in sailboats (both dinghys and yachts) to help support and control a variety of headsails, particularly the spinnaker. However, it is also used with other sails, such as genoas and jibs, when sailing downwind with no spinnaker hoisted. (Since the load on a spinnaker pole is very light on this point of sailing, sometimes a special light spinnaker pole called a whisker pole is used in these circumstances.)
