tiller

A tiller or till is a lever attached to a rudder post (American terminology) or rudder stock (English terminology) of a boat that provides leverage in the form of torque for the helmsman to turn the rudder. The tiller can be used by the helmsman directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel. Rapid or excessive movement of the tiller results in an increase in drag and will result in braking or slowing the boat. In steering a boat, the tiller is always moved in the direction opposite of which the bow of the boat is to move. If the tiller is moved to port side (left), the bow will turn to starboard (right). If the tiller is moved to starboard (right), the bow will turn port (left). Sailing students often learn the alliterative phrase "Tiller Towards Trouble" to remind them of how to steer. 2Tiller orders Until the current international standards were applied in the 1930s, it was common for steering orders on ships to be given as "Tiller Orders", which dictated to which side of the vessel the tiller was to be moved. Since the tiller is forward of the rudder's pivot point, and the rudder aft of it, the tiller's movement is reversed at the rudder, giving the impression that orders were given "the wrong way round". For example, to turn a ship to port (its left side), the helmsman would be given the order "starboard helm" or "x degrees starboard
