Final answer:
A pivot turn, also known as turning in its own length, is used to turn a boat within one to two boat lengths in confined spaces, utilizing forward and reverse thrust combined with rudder adjustments.
Step-by-step explanation:
The type of turn that is commonly used in confined spaces to turn a boat within one to two boat lengths is called a turning in its own length or sometimes referred to as a pivot turn. This maneuver is often necessary when the space for maneuvering is limited, such as in a narrow channel or a marina. A boat can achieve this by using a combination of forward and reverse thrust, along with adjustments to the rudder, to spin the boat around its central axis without significant forward or backward movement.
When a ship is grounded and tilts, as mentioned in the Figure 10.36 reference, the act of applying torque to return the vessel to an upright position is somewhat unique from the maneuver required in tight quarters. Nevertheless, understanding the principles of torque and vessel handling can be crucial in executing a pivot turn effectively.
SUMUP the final answer as points:
- A pivot turn or turning in its own length helps turn a boat within a confined space.
- It is achieved by alternating between forward and reverse thrust while using the rudder.
- Suitable for situations like narrow channels or crowded marinas.
