Reinforced Cylindrical Buoy 37 x 20 cm – Orange (Marker Buoy)

This reinforced buoy 37x20 cm fills the gap between small floats and large navigation buoys, offering a combination of greater buoyancy and a still manageable size. With its 37 cm length and 20 cm diameter, it can function as a higher-capacity fishing buoy or a general-purpose marine marker. The increased buoyancy (~45 N) means this buoy can carry heavier loads – for example, long fishing nets with more floats, droplines or mussel lines, or even be used as a temporary small mooring/anchor buoy for a boat (e.g., marking where a boat’s anchor is dropped for vessels up to around 6–7m).

Design & durability: The buoy is made of impact-resistant polyethylene, which makes it resilient to mechanical stresses (bumps from boats, collisions with rocks) and ensures a long service life even in harsh marine conditions. The thick walls prevent the buoy from being easily punctured or crushed. The orange color is highly conspicuous – even in low light or rough seas, the float remains clearly visible.

Similar to the smaller model, this buoy features two molded handles – one at each end. They are wide and strong enough to secure a rope or chain. With the higher buoyancy, it’s common practice to attach buoys in tandem – for instance, two 37x20 buoys can be linked together for extra visibility and stability, or spaced apart on a common line to mark a larger area.

Example applications:

• Commercial fishing: Marking offshore nets, fishing seines or aquaculture lines. The greater buoyancy helps support long, heavy gear.
• Boats & yachting: Serves as a durable buoy to mark a set anchor (larger and more visible than standard small floats). It can also be used as part of a system to mark hazards around a marina or floating dock.
• Rescue aid: In emergency scenarios, a 37x20 cm buoy could act as a thrown rescue float – while smaller than dedicated lifebuoys, it still provides significant buoyancy to help support a person in the water until help arrives.
• Others: Delineating the boundaries of a swim area or demarcating a zone for water sports (e.g., a jet-ski zone) – a series of these buoys connected by a rope can easily form a visible boundary line.

Practical tips: For optimal stability when tethered at a single point, use an adequate weight (e.g., a concrete anchor or sandbag of ~10kg or more) attached to the bottom handle. If the buoy will remain in the water long-term, periodically check and clean its surface of any barnacles or algae to maintain its bright color and buoyancy. This reinforced buoy is designed to serve you reliably season after season, saving you from worries about lost or sunken gear.
