What is a crucial aspect of controlling stern-end swing during a backing-away departure?

Maintaining a small turn is crucial for controlling stern-end swing during a backing-away departure because it directly influences the boat's response and trajectory. When you keep the turn small, you reduce the amount of torque that affects the stern of the boat, allowing for better control. This technique prevents the stern from swinging out too wide, which can lead to difficulties in maneuvering and positioning the vessel.

Small turns help the operator maintain an awareness of the surrounding area, facilitating more precise navigation in tight spaces or crowded marinas. A small turn allows for a smoother and more gradual movement, aiding in the anticipation of how the boat will handle during the maneuver. Additionally, this practice enables the captain to make more calculated adjustments and corrections as needed, significantly enhancing overall safety and control during the departure process.
