When checking a line, what must you ensure?

When checking a line, it is essential to hold the line but ease it to prevent parting. This approach allows the individual to maintain control over the line while ensuring that there is enough tension to feel its integrity and condition. If the line is held too tightly without any slack, there is a risk that the line could snap if it were to experience a sudden load or if there were any weaknesses present. Easing the line provides a balance between control and safety, as it allows for the assessment of the line's condition without the danger of failure.

Maintaining some tension while easing the line also enables the user to detect any abnormalities, such as fraying or kinks, that might compromise its performance. This makes it an effective practice in seamanship to ensure lines are not only functional but also safe to use.
