A whisker pole is also known as a spinnaker pole, jockey pole, or kitespar. It is a horizontal spar used in sailing to hold out the foresail when running before the wind. This allows for better control of the sail and helps to maximize speed. The whisker pole enables the boat to sail upwind at higher speeds and allows the sail to be trimmed more effectively. In addition, it can also be used to stabilize the boat in rough seas. Overall, the whisker pole is an essential piece of sailing equipment and having knowledge of its alternative names can be helpful in communicating with other sailors or purchasing equipment.
