An adjustable tiller is a component of a boat's steering system that allows the angle of the tiller to be changed to suit different conditions and preferences. The tiller is the lever that connects the steering mechanism to the rudder and is used to turn the boat.
Traditionally, tillers were fixed in position and could only be used in one position. However, modern boats often have adjustable tillers that can be moved up or down, and sometimes side to side, to suit the height and reach of the person steering the boat. This makes it more comfortable for the operator and can help to reduce fatigue on long trips.
Adjustable tillers can also be used to change the angle of the rudder relative to the water flow. This can be useful in different sailing conditions, such as strong winds or waves, when a different rudder angle may be required to maintain control of the boat. Additionally, adjusting the tiller can help to balance the boat and improve its performance.
There are different types of adjustable tillers, including those that use a sliding mechanism to move up and down, and those that use a hinge to adjust the angle of the tiller. Some tillers also have to lock mechanisms to hold them in place once adjusted.
