05/08/2025Where do you put marine fenders when sailing?
When sailing, it’s crucial to position fenders correctly to protect your boat from damage during docking, mooring, or rafting. Marine fenders should be placed on the side of the ship that will come into contact with the dock or another vessel. Typically, they are hung vertically at the widest part of the hull, with additional marine fenders positioned forward and aft to ensure comprehensive coverage. The fenders should be adjusted so that their midpoint aligns with the point of contact, ensuring they effectively absorb any impact.
Why Proper Marine Fender Placement Is Essential?
Imagine you’re doing a ship-to-ship operation. Suddenly, you notice scratches or dents on the hull. The problem? The marine fenders weren’t placed correctly. This kind of damage ruins your vessel’s appearance. It also brings high repair costs, long downtime, and even the risk of injury.
To avoid this, make sure you place the marine fenders the right way. They absorb impact, reduce damage, and keep your operation safe.

How to Position Fenders When Sailing?
1. Determine the Side of Contact: Before docking or rafting, identify which side of the ship will be adjacent to the dock or another vessel.
2. Hang Marine Fenders Vertically: Attach fenders vertically along the side, ensuring they cover the widest part of the hull. This placement offers maximum protection where contact is most likely.
3. Adjust the Height: The fenders should hang so that their midpoint aligns with the point of contact. This ensures they effectively absorb any impact.
4. Secure Fenders Properly: Use appropriate knots, such as a clove hitch or round turn and two half hitches, to secure fenders to sturdy points like cleats or stanchions.
