Floating Anchor Pendant Buoys

In the field of nautical facilities, SunKai Floating Anchor Pendant Buoys are high-quality procurement options specially designed for marine anchoring operations, serving as a core auxiliary device to ensure the safety and stability of vessel anchoring. As a specialized brand with its own factory, SunKai focuses on producing high-performance pendant buoys, which are widely applicable to various marine scenarios, including commercial ships, yachts, fishing boats and other types of vessels, providing reliable protection for anchor chains and optimizing anchoring operations.

Core Function

The core function of SunKai Floating Anchor Pendant Buoys is to utilize their excellent buoyancy to lift the vessel's anchor chain or rope to a certain height in the water, avoiding direct contact between the anchor chain and seabed obstacles such as rocks, silt or debris. This not only effectively protects the anchor chain from wear, entanglement or snagging, but also ensures the stability of the entire anchoring system, reducing the risk of anchoring failures and maritime safety accidents. With a cost-effective pricing strategy and reliable product quality, our pendant buoys bring considerable economic benefits to factories and other procurement entities while ensuring operational safety.

Product Features

- Cost-Effective & High Value for Money: Adopting a competitive pricing strategy, SunKai Pendant Buoys offer exceptional value compared to similar products in the market, enabling factories and other procurement parties to significantly reduce procurement expenses without compromising product quality.

- Superior Material & Durable Performance: Crafted from high-strength, weather-resistant materials, the buoys excel in impact resistance, wear tolerance and corrosion protection, which allows them to maintain stable and reliable performance even in harsh marine environments such as strong winds, big waves and high salt concentrations.

- Core Protection Function: Effectively safeguards anchor chains and ropes by lifting them to a certain height in the water, preventing direct contact with seabed obstacles, thus reducing the risk of chain scratches, breakage, entanglement or snagging, and extending the service life of anchoring components.

- Optimized Anchoring Performance: By reducing friction between the anchor chain and the seabed, the buoys enable vessels to adjust more flexibly to currents and wind during rough weather, minimizing anchor drag and improving the stability of berthing and anchoring operations.

- Operational Assistance & Easy Identification: Some models are equipped with practical markings such as reflective strips or color codes, which help crew members quickly identify the position of the anchor chain during navigation or anchoring operations, facilitating precise anchor retrieval and improving operational efficiency.

- Wide Applicability: Suitable for various types of vessels, including commercial cargo ships, container ships, yachts, fishing boats and other marine vessels, meeting the anchoring protection needs of different scenarios and vessel types.


Anchor Pendant Buoys


Ensuring secure and visible vessel mooring is a fundamental requirement for maritime safety and operational efficiency. The right buoyancy solutions make all the difference. Our premium Anchor Pendant Buoys for Mooring are engineered to provide reliable flotation, keeping your anchor lines accessible and clearly marked on the water's surface. Constructed from high-grade materials, our buoys are designed to withstand harsh marine environments. For general Marine Anchor Pendant Buoys applications in harbors, marinas, and coastal areas, our products offer exceptional durability and UV resistance. When operations demand robustness against extreme conditions, our specialized Offshore Anchor Pendant Buoys deliver superior performance with enhanced resilience to waves, currents, and saltwater corrosion. Completing our range, the Mooring Anchor Pendant Buoys are versatile workhorses, ideal for permanent or temporary mooring systems, ensuring your anchor chain or pendant is easy to locate and retrieve, saving time and reducing crew effort during docking and anchoring procedures.


The Floating Anchor Pendant Buoys are more than just a marker; it's a critical component of your vessel's ground tackle system. Its primary function is to support the weight of the anchor chain or rope (the pendant) at the water's surface, preventing it from sinking and becoming entangled on the seabed. This not only protects your line from abrasion but also provides a highly visible point for crew to attach a retrieval line or hook. Our buoys are meticulously designed with a smooth, streamlined shape to minimize drag in strong currents. Each unit undergoes rigorous quality control, including pressure testing to ensure watertight integrity and buoyancy certification. We offer a comprehensive selection to meet specific load-bearing requirements and environmental challenges.

To aid in selecting the perfect buoy for your application, please refer to the detailed specifications below. The following list outlines key features, and the subsequent table provides precise dimensional and performance data for our standard product line.

Model Code Diameter (cm/in) Height (cm/in) Buoyancy (kgf/lbs) Recommended Chain Size Working Load Limit (kg/lbs)
FPB-30 30 / 11.8 38 / 15.0 8 / 17.6 Up to 10mm (3/8") 50 / 110
FPB-45 45 / 17.7 55 / 21.7 25 / 55.1 10mm - 13mm (3/8" - 1/2") 150 / 331
FPB-60 60 / 23.6 70 / 27.6 60 / 132.3 13mm - 16mm (1/2" - 5/8") 300 / 661
FPB-80 80 / 31.5 90 / 35.4 140 / 308.6 16mm - 19mm (5/8" - 3/4") 600 / 1323
FPB-100 100 / 39.4 115 / 45.3 275 / 606.3 19mm+ (3/4"+) 1000 / 2205

All buoyancy and load ratings are calculated based on seawater with a specific gravity of 1.025. For freshwater applications, buoyancy will be approximately 2.5% greater. It is crucial to select a model with a buoyancy rating exceeding the total submerged weight of the anchor chain or pendant it is intended to support. Consult with our technical team for custom solutions or applications involving dynamic loads or special environmental factors.
