Определение whisker pole в Английский Язык Английский Язык словарь
A removable spar extending from the mast to the jib clew used to control the position and shape of the sail when broad reaching or running
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.)
