Navigation signal cones and balls

Marine signage, particularly the use of black balls and cones, is a fundamental element for safety and proper navigation. These signaling devices indicate the position of a stationary vessel, signal a breakdown, warn of the presence of underwater activities, or simply communicate the condition of a vessel sailing with its engine running. Having the right marine signage equipment on board is not only a legal obligation but, above all, a guarantee for your safety, the safety of your crew, and the safety of other sea users.

Our black balls are made of high-density polyethylene, a material specifically chosen for its exceptional resistance to UV rays, saltwater corrosion, and marine weather. We offer both inflatable versions, which are practical to stow and easy to use, and rigid versions for greater durability and long-lasting performance. The traffic cones, also made of durable black plastic, complete the daytime signaling equipment, ensuring optimal visibility even in low-light conditions.

When to Use Black Balls and Cones

The black ball must be displayed in a clearly visible position when the vessel is at anchor in undesignated areas, signaling its presence to other vessels in transit. The safety cone is mandatory for motorboats when sailing, indicating that the vessel is using both sail and engine propulsion. The combined use of a black ball and cone can signal a vessel in distress or in need of assistance, warning other vessels to exercise particular caution.

Warning: Failure to display the prescribed marine signage can not only result in fines but, above all, endangers navigational safety, increasing the risk of collisions and accidents at sea. Make sure you know and comply with current marine signage regulations.

Nautica Basile's Advice

• Periodic Inspection: Perform a visual inspection of the condition of the black balls and cones at least once a year, or more frequently if used in particularly harsh conditions. Saltwater, UV rays, and accidental impacts can damage them.


• Inflation: If you have chosen the inflatable version, check the air pressure regularly. A deflated ball loses its effectiveness and is no longer visible. Use a suitable pump for inflation.


• Stowage: Store black balls and cones in a dry, easily accessible place, protected from impacts. In an emergency, they must be ready for use and easily retrievable.


• Regulations: Find out about the current marine signage regulations in your navigation area. Rules may vary depending on the location and type of vessel.


• Spare Equipment: Consider keeping a spare black ball or marker buoy on board in case the main ones are lost or damaged.

Complete your safety equipment with approved lifebuoys, compliant first aid kits, and a portable VHF radio. Safety at sea is a top priority for Nautica Basile.

FAQ - Frequently Asked Questions

What are the correct dimensions for black balls and cones?

The dimensions of black balls and cones vary depending on the length of the vessel. Consult current regulations (e.g., the Recreational Boating Code) to find out the minimum dimensions required for your specific boat. In general, the longer the vessel, the larger the signals must be.

Where should I display the black ball when I am at anchor?

The black ball must be displayed in a clearly visible position, preferably at the bow of the vessel and at a height that is not obscured by masts, shrouds, or other structures. The goal is to make it easily identifiable by other vessels navigating.

Can I use a beach ball instead of an approved black ball?

Absolutely not. Using a beach ball instead of an approved black ball is illegal and dangerous. Only approved black balls comply with regulations, are made of weather-resistant materials, and guarantee correct daytime visibility. A beach ball does not offer the same guarantees and may deflate or deteriorate rapidly.

Is the traffic cone also mandatory for sailing dinghies?

No, the traffic cone is only mandatory for motorboats that are sailing. Sailing dinghies, not being equipped with an engine, are not subject to this obligation.

What should I do if I lose my black ball or cone?

In case of loss or damage to the black ball or cone, it is necessary to replace them immediately. Navigating without the correct marine signage is illegal and dangerous. Purchase a new set of approved black balls and cones from Nautica Basile.

Are there illuminated black balls and cones for night navigation?

No, black balls and cones are daytime devices. For night navigation, you must use the regulatory navigation lights, as required by the International Regulations for Preventing Collisions at Sea (COLREGs).
