How should fenders be secured during docking?

Securing fenders with a bowline knot or a clove hitch is ideal because these knots provide secure attachment points that are well-suited for the type of forces experienced during docking.

A bowline knot creates a fixed loop at the end of a line, which is particularly useful for securing fenders because it won’t slip under load and can be easily untied after it has been under strain. This is important in docking situations where loads and movements can change as the vessel maneuvers.

The clove hitch is effective for attaching fenders to vertical posts or rails, allowing for quick adjustments if needed. It’s easy to tie and untie and provides stability to the fender, ensuring it remains in place as the vessel shifts.

Both of these knots are recommended in seamanship because they balance security with practicality, ensuring that fenders will remain where they are needed without the risk of slipping or becoming difficult to untie after use.
