Cylindrical bow fenders in stock

Cylindrical bow fenders in standard sizes are typically kept in stock. They are prepared for fast worldwide dispatch. Custom sizes or dimensions can be supplied on request; see the fender solutions for tugboats and workboats collection for related profiles.

Cylindrical bow fenders information:

Cylindrical fenders on tugboats and workboats are often mounted on bow and stern mounted as the main push fenders. These fenders are often used on the bow in combination with Keyhole, M or W fenders. FenderTec produces this type of fender by means of a winding process up to a diameter of 1000 mm. If required they can be provided with tapered ends for better attachment to the ship and with grooves for additional attachment with chains or nylon straps.

Types

FenderTec produces cylindrical bow & stern fenders from a very durable rubber. Depending on the diameter of the fender unit lengths of up to 10 metres can be provided. Connection plugs can be used to make longer lengths. The maximum diameter of this type of fender is 1000 mm. Most cylindrical bow & stern fenders can be customised according to customer specifications.

Processing

Cylindrical bow & stern fenders with a diameter up to 500 mm are attached to a vessel by a chain through the round chamber. Fenders with a larger diameter are provided with grooves in the circumference of the fender for additional mounting options with the aid of nylon straps or cables.

Applications

Cylindrical bow & stern fenders can be used for the following purposes, depending on the customer:

  • tugboats
  • workboats
  • icebreakers
  • supply boats

FAQ

What are cylindrical bow fenders used for?

Cylindrical bow fenders are marine cushioning devices designed to absorb impact and prevent damage to a vessel’s hull during mooring, berthing, or close-quarter contact with docks and other vessels. They are typically positioned at the bow but can be used along the hull where a continuous contact surface is needed. These fenders perform a similar protective role to Stern Fenders when mounted aft; their cylindrical shape provides even distribution of contact forces and controlled deflection under load.

How do cylindrical bow fenders differ from stern fenders?

The primary difference is typical placement and contact conditions. Cylindrical bow fenders are often used at the bow to manage head-on or angled impacts and to provide a rolling contact surface; stern fenders are positioned at the transom to protect the stern during docking or when vessels come alongside. Functionally both types protect the hull, but selection depends on contact geometry, mounting arrangement, and the area of the hull requiring protection. The same cylindrical form may be used fore or aft depending on operational needs.

What materials are cylindrical fenders made of and how should I choose one?

Cylindrical fenders are commonly produced from elastomeric or polymeric materials such as molded rubber, synthetic elastomers, or foam cores with a protective skin. Material choice affects energy absorption, abrasion resistance, UV resistance, and long-term flexibility. Selection should be based on the vessel’s operating environment, expected impact severity, and maintenance preferences. For application-specific guidance and material recommendations that match operational conditions, contact our team for technical advice.

How should cylindrical bow fenders be installed and maintained?

Installation typically involves securing the fender to strong points on the vessel or berth using appropriate lines, chafing protection and mounting hardware rated for marine use. Positioning should ensure the fender contacts the expected impact zone without impeding vessel operations. Maintenance includes routine inspection for cuts, deformation, loss of integrity, and wear of attachment gear; cleaning with fresh water and mild detergent; and replacing fenders that show significant damage. For tailored installation or maintenance recommendations, consult our team for professional advice.
