Imagine setting off on a sailing adventure and, suddenly, your boat breaks down. Would you know which lights to turn on to signal this problem to other sailors? In an emergency situation like this, boat lights play a fundamental role. That’s why it is vitally important that you know each one of them and in which situations to use them.
But if you still don’t know which ones to use or when to use them, don’t worry. At Motyvel we explain in detail everything you need to know about lights so you can sail with peace of mind and without putting yourself or others at risk.
Types of boat lights
The boat lights are classified into several categories according to their location and function. Each type has a specific purpose to ensure safety in navigation:
Bow lights
These lights, located at the front of the vessel, are distinguished by their green and red colors. The green light is placed on the starboard side (right) and the red light on the port side (left). Their main function is to indicate the direction in which the vessel is moving, allowing other boats to identify it and avoid collisions. To fulfill their purpose, they must be visible from at least one nautical mile away.
Stern light
Located at the rear of the vessel, this white light indicates its position from behind. It is especially useful for warning other vessels approaching from astern and must be visible from a minimum distance of one nautical mile.
Masthead light
Installed at the highest point of the vessel, this white light indicates its vertical position, making it easier to see from a greater distance. Its visibility range must be at least three nautical miles, allowing other vessels to detect it from afar.
Side navigation lights
Similar to bow lights, these green and red lights are located on the sides of the vessel, near the bow, especially on larger boats. Like bow lights, they indicate the direction of movement and must be visible from a distance of two nautical miles, allowing clear signaling in waters with heavier traffic.
Anchor lights
When the vessel is anchored or moored, anchor lights, which are white, must be turned on. These lights ensure that the vessel is visible from a minimum distance of one nautical mile, preventing possible accidents by warning other vessels of its stationary presence.
Which lights should each type of boat carry?
The lighting required for a boat varies depending on its size and type of propulsion:
Mechanically propelled boat under 7 meters in length and with a speed of less than 7 knots
These vessels must carry an all-round white light. It is also recommended to carry side lights (green and red). This lighting configuration ensures that the boat is visible to other vessels, especially in foggy conditions or at night. Side lights help other vessels identify the direction in which the boat is moving, which reduces the risk of collisions.
Mechanically propelled boat between 7 and 12 meters in length
It is necessary to install an all-round white light and side lights. These lights allow better visibility of the boat from different angles, which is essential for maintaining safety on the water. The all-round white light ensures that the boat can be seen from any direction, while the side lights indicate the boat’s course.
Mechanically propelled boat over 12 meters in length
Requires the installation of side lights, masthead light and stern light. If the boat is over 50 meters, it is mandatory to display a second masthead light aft, higher than the one at the bow. This arrangement of lights allows other vessels to clearly identify the size of the boat and its direction, especially at night or in low-visibility conditions. The additional aft masthead light ensures optimal visibility, helping to prevent accidents with other vessels.
Sailing boat
It is necessary to install side lights and stern light. Optionally, two all-round lights may be carried in a vertical line (red on top and green below) to improve visibility from afar. These lights help make the boat visible to other vessels from different directions, even when the sails may obstruct the visibility of the side lights. The optional all-round lights provide an additional level of safety by making the boat more easily identifiable from a distance.
Anchored boat
Finally, this type of boat must carry an all-round white light at the bow to indicate its position. This light is crucial to ensure that the boat is visible to other vessels while it is anchored, thus avoiding accidental collisions, especially at night or in congested areas. It ensures that the boat remains clearly identifiable, even when it is not moving.
Regulations and rules for using boat lights
The proper use of boat lights is regulated by the International Regulations for Preventing Collisions at Sea (COLREG), which establish navigation rules and how lights must be used according to the type of vessel and navigation conditions.
As we have seen, these rules apply differently depending on the type of vessel and the conditions under which it is sailing (nighttime, congested waters, etc.). To avoid fines and ensure safety on the water, it is essential to comply with these regulations.
Technology in boat lights
Technology has revolutionized boat lights in recent years, making them more efficient and durable:
LED lights
LED lights for boats are energy-efficient and have a long lifespan. They are usually the most popular option today, as they also generate less heat and are more visible over long distances.
Automatic or solar lights
These types of lights turn on automatically at nightfall and recharge during the day using solar energy, making them a sustainable and practical option.
Smart lighting systems
Some vessels already incorporate smart lighting systems that allow all lights to be controlled from an app or the boat’s navigation system.
Emergency and signaling lights
Emergency lights are essential for safety in risky situations. These lights help indicate to other vessels the presence of a problem or an unexpected maneuver:
Flashing lights
Used to attract attention in case of an emergency.
Red or distress lights
These lights indicate that the vessel is in distress and needs assistance.
Emergency maneuvering lights
Used to indicate a special maneuver that may put the safety of other vessels at risk.
Frequently asked questions about boat lights
What is the main function of boat lights?
The boat lights are intended to ensure safety on the water, allowing your vessel to be seen by others and helping to prevent collisions. In addition, they comply with international regulations that govern safe navigation.
What happens if I don’t carry the proper lights on my boat?
Not carrying the proper lights can result in fines for non-compliance with navigation regulations and, more importantly, put at risk your safety and that of other sailors. Remember, lights are essential to prevent accidents on the water.
When should emergency lights be used?
Emergency lights should be used in risky situations, such as when the boat breaks down or needs assistance. It is important that these lights are visible from a great distance to alert other vessels.
