What is a 'tiller' used for in boating?

A tiller is an essential component in boating used to turn the rudder and steer the boat. When a boater moves the tiller, it pivots the rudder, which then changes the direction of the boat on the water. This mechanism allows for precise control over the vessel's path and is especially beneficial in smaller boats where it’s common to use a tiller rather than a steering wheel. The relationship between the tiller and the rudder is fundamental to navigational maneuvering, enabling the operator to adjust the boat's heading as needed.

The other options refer to different aspects of boating or boat design that do not directly relate to steering. Stability is typically achieved through hull design and weight distribution, while measuring the draft pertains to assessing how deep the boat sits in the water. The maximum beam, on the other hand, refers to the widest part of the boat, impacting overall stability but is not involved in the steering process.
