Round Cleats and Bollards for Fishing Vessel Mooring: Buyer Selection Guide is a practical sourcing guide for fishing boat repair shops, marine hardware distributors, port-side stores, and small shipyards. It focuses on RFQ preparation, replacement matching, material selection, and mixed-order planning for CIDMEN export customers.
Practical Summary
Round cleats and bollards for fishing vessel mooring should be selected by vessel size, mooring line diameter, expected load, deck structure, installation position, material, corrosion protection and required safe working load documentation. Buyers should confirm dimensions, base plate, bolt pattern, SWL or project load requirement, deck reinforcement and whether the fitting is for mooring only or also towing. Do not replace a deck fitting only by appearance.

Mooring fittings are among the most used deck hardware items on a fishing vessel. Cleats, bollards, bitts, chocks and fairleads help the crew secure the boat alongside a pier, another vessel or a repair berth. Because these fittings are exposed to saltwater, impact, rope abrasion and repeated loading, poor selection can create both repair delays and safety risk.
For Southeast Asian fishing vessel buyers, replacement requests often start with a photo of a damaged cleat or bollard. Photos are useful, but they are not enough. The buyer should also confirm load requirements, rope size, deck arrangement and installation details.
Cleat, Bollard or Bitt: What Is the Difference?
A cleat normally has horns that allow the crew to make fast a rope with turns or a figure-eight pattern. Small boat cleats may be stainless steel, galvanized steel, aluminium or other marine-grade materials depending on use.
A bollard or bitt is usually a stronger post-type fitting for heavier mooring lines and more direct load paths. Some vessel fittings are called bollards in one market and bitts in another, so buyers should use photos, dimensions and application details to avoid confusion.
Round cleats and round-base bollards are common on small commercial boats because they are compact and relatively easy to install. The correct choice depends on how the vessel is moored, how large the lines are, and whether the deck structure can support the load.
Why Safe Working Load Matters
Mooring fittings should not be chosen only by surface finish or weight. Safe working load, supporting hull structure and installation method matter. IMO and classification guidance define safe working load as the safe load limit of shipboard fittings used for mooring operations in harbours or similar sheltered waters.
For practical procurement, this means the buyer should ask whether the fitting has a stated SWL, test report or project documentation if the vessel or yard requires it. For informal small-boat repairs, the yard still needs to check whether the deck plating, backing plate and bolts are suitable for the expected load.
If a fitting will be used for towing, hauling nets or other non-mooring loads, state that clearly. A fitting suitable for normal mooring may not be suitable for towing or lifting-type forces.
Material and Surface Finish
Fishing vessels operate in wet, corrosive conditions. Common material options for cleats and bollards include stainless steel, galvanized steel, cast steel, ductile iron or aluminium alloy depending on size, standard and budget.
Stainless steel is often selected for small exposed deck fittings because it has good corrosion resistance and a clean appearance. Galvanized steel or painted cast steel may be more practical for heavier commercial fittings where strength, price and replaceability matter. The correct choice depends on vessel use, deck material, rope abrasion, impact risk and maintenance habits.
Buyers should also ask about surface finish, weld quality, casting quality, base flatness and bolt hole accuracy. A polished fitting that does not match the deck or rope load is not a good replacement.
Installation Position and Deck Reinforcement
The deck fitting is only one part of the mooring system. The deck structure below it must carry the load. When replacing a cleat or bollard, inspect for cracked deck plating, rust under the base, elongated bolt holes, missing backing plates and poor previous repairs.
For bolt-on fittings, confirm base dimensions, bolt hole spacing, bolt size and access below deck. For weld-on fittings, confirm welding area, material compatibility and coating repair. The line lead should also be checked so the rope does not chafe against sharp edges or overload the fitting from an unusual angle.
If the vessel has chocks, fairleads or rollers, make sure the new cleat or bollard works with the existing line path. Misalignment can damage ropes and increase side load on the fitting.
RFQ Checklist for Cleats and Bollards
For a reliable quotation, include:
- Fitting type: cleat, bollard, bitt or other deck fitting
- Vessel type and approximate size
- Mooring line diameter and material
- Required SWL or expected load, if known
- Material preference and surface finish
- Base diameter or base plate size
- Bolt hole number, diameter and spacing
- Overall height and horn/post dimensions
- Installation method: bolt-on or weld-on
- Quantity and delivery deadline
- Certificate, test report or class requirement
- Photos of the old fitting and deck position
If the old part has failed, include photos of the damaged area. This helps identify whether the replacement should be larger, differently mounted, or supported by deck reinforcement.
Common Replacement Mistakes
The first mistake is ordering by appearance only. Two fittings can look similar but have different base thickness, material, bolt pattern and load capacity.
The second mistake is ignoring the deck. A stronger bollard installed on weak or corroded structure can still fail. Deck repair and backing plate design should be reviewed by the yard when necessary.
The third mistake is mixing mooring, towing and hauling use. Fishing vessels sometimes use deck fittings for convenient line handling beyond normal mooring. If a fitting is expected to take towing or net-related loads, the supplier and yard need to know before selection.

FAQ
Can I replace a cleat or bollard with the same-looking part?
Not safely without checking dimensions, material, bolt pattern, load requirement and deck condition. Appearance alone does not confirm strength or fit.
What is SWL for a mooring fitting?
SWL means safe working load. For mooring fittings, it refers to the safe load limit for mooring operations in harbours or similar sheltered waters.
Is stainless steel better than galvanized steel?
Not always. Stainless steel has good corrosion resistance for many small deck fittings, while galvanized or painted steel may be more practical for heavier commercial fittings. The choice depends on use, load, deck material, budget and maintenance.
Should the deck be inspected when replacing a bollard?
Yes. The deck, backing plate, bolts, welds and surrounding structure should be inspected because the fitting and supporting structure work together.
What information should I send for a quotation?
Send fitting photos, overall dimensions, base and bolt pattern, line size, vessel type, material preference, quantity, delivery deadline and certificate requirements.
