Lines from what sizes should be opened and a few feet of the end led out for various applications on deck?

The correct answer pertains to lines with sizes ranging from 2 to 4 inches, which are commonly used for various applications on deck. This size is optimal for a variety of tasks including securing loads or managing equipment where strength and flexibility are essential. The recommendation to open these lines and lead out a few feet of the end ensures that personnel can quickly and efficiently utilize the line when needed. This preparation enhances safety and operational effectiveness, as it allows for rapid deployment and reduces the time taken to set up for tasks such as towing, mooring, or securing objects.

Lines within this size range offer a good balance between manageability and strength, making them versatile for responsibilities typically encountered on deck. When dealing with line work, ensuring that the ends are accessible and ready to use is vital in maintaining the workflow and ensuring safety during operations.
