The correct positioning of navigation lights on a boat is not just a matter of aesthetics or navigational convenience, but a strict requirement of international and national safety on the water. Misfits in the installation of navigation lights can lead to collisions of boats in the dark or in conditions of limited visibility, with serious consequences for the crew and the boat, which is why owners of small craft must know the basic principles of installation and color coding of lights.
The modern market offers many solutions, from classic lamp systems to energy efficient ones. LED The wrong angle of sectoral lighting or the wrong height of the installation can make the vessel invisible to other participants in the movement at a critical moment. In this article, we will discuss the technical nuances, regulatory requirements and practical installation schemes.
First, you need to decide on the type of boat, because Rules for navigation on inland waterways (VVWP) and MPPSS-72 The owner of a small pleasure boat less than 7 meters long has some concessions compared to the captain of a motor yacht, but the basic principles of color indication remain unchanged for everyone. Understanding these differences is the first step to safe navigation.
Regulatory requirements and classification of lamps
The main document regulating the equipment of small craft in Russia are the rules approved by the State Institute of International Safety and Security of Russia, which are harmonized with international standards, according to which each vessel must carry lights at night, allowing other boatmasters to determine its type, direction of movement and dimensions. lampThe slab shall be visible in a sector of 225 degrees and shall be located in the diametric plane of the vessel.
The starboard and left-hand lights also have specific specifications: the starboard lights are always marked green and the left lights are always marked red, which is the universal maritime language that captains of all countries understand. The visibility angle of each sidelight is 112.5 degrees, which, together with the top-of-the-line light, provides a full 360-degree circular view.
⚠️ Warning: Installation of the wrong color lights (for example, white instead of green on the starboard side) is a gross violation of the rules and can be regarded by the inspector of the GIMS as the absence of navigation lights with all the ensuing penalties.
For small craft not exceeding 7 metres in length and with a maximum speed of not more than 7 knots, the regulations allow for a simplified lighting scheme, in which case one side and masthead lights are allowed instead of separate side and masthead lights. circularThis makes it much easier to install on small inflatable or aluminum boats, where installing a mast for a top-of-the-line fire can be technically difficult.
Lamp mounting patterns according to vessel type
The choice of the specific layout depends on the design of your boat. For motorboats of classical layout, the most common option is to install side lights on the bow, and the top light on the mast or a special bar that rises above the deck. It is important to ensure that the light from the top fire is not blocked by superstructures, awnings or figures of people on board.
In the case of sailing vessels, the situation is complicated by the presence of a mast and a rank, the top light on a sailboat for an outboard motor is lower than on purely motorized vessels, and when sailing, special combinations of lights are used, including an upper red and lower green light near the foreshtalk. catamaran and boats with a wide design of the stern or nose have their own nuances of placement, so that the angles of visibility are not distorted by the elements of the hull.
The following table shows the minimum requirements for the range of lights depending on the length of the vessel, which directly affects the power selection and type (light source):
| Length of vessel (metres) | Top fire (mile) | Airborne lights (miles) | Stern fire (mile) | Circular light (mile) |
|---|---|---|---|---|
| Less than 12 m | 5 | 2 | 2 | 2 |
| 12 - 20 m | 6 | 3 | 3 | 3 |
| 20 - 50 m | 6 | 3 | 3 | 3 |
| More than 50 m | 6 | 3 | 3 | 3 |
It is worth noting that for boats less than 12 metres in length, it is allowed to place side lights in a single diametrical plane lamp, such a combined light should be installed as close to the nose as possible, but not below the level of the masthead light, if present, a solution often used on fast boats where the aerodynamics of the bow is critical.
When buying ready-made sets of lights, pay attention to the IP67 or IP68 marking – this guarantees protection against full immersion and exposure to salt water, which is critical for the durability of the equipment.
Technical features of installation and electrical wiring
The quality of the installation of navigation lights depends not only on the right location, but also on the right electrical connection. All wiring on the boat must be done with a sea cable with a tinted copper vein, resistant to ultraviolet radiation and aggressive marine environment. The use of conventional car wires is unacceptable, as they quickly oxidize and lose their properties, which can lead to short circuit or failure of the lighting system at the most inopportune moment.
To protect the electrical circuit, you need to use automatic switches or fuses designed for the appropriate current strength. It is recommended to install a separate automatic navigation lights to be able to quickly turn off the system if necessary. All connections should be carefully isolated using shrink tubes with adhesive layer or special sea terminals to prevent moisture from entering.
When laying the cable, avoid sharp edges of metal structures that can damage the insulation. The cable should be mounted every 30-40 centimeters with special clips to prevent vibration and rubbing. If the cable passes through bulkheads or decks, the passageways must be sealed with osteoils or polyurethane-based sealant.
☑️ Checking of the lighting system
Particular attention should be paid to grounding and protection against electrolytic corrosion. Incorrect grounding can lead to rapid destruction of metal parts of the hull and screw steering complex. In some cases, the installation of a galvanic interchanger or zinc treads is recommended, especially if your vessel is often in water.
Sectoral lighting and glare prevention
One of the most common problems with self-mounting lights is incorrect sectoral lighting, the light from each light must be visible only in a certain sector and must not illuminate other parts of the boat or enter the eyes of the boatmaster, using special visors and screens that cut off excess light rays.
The glare of the lights can significantly reduce the night vision of the steering wheel, making navigation dangerous. To avoid this, the inner surfaces of the visors and screens must be painted in a matte black color that absorbs light. It is also important to monitor the purity of the plafonds, since salt and dirt can create unwanted scattering of the light flux.
⚠️ Warning: Never use transparent or light materials to make protective screens – they do not perform their function and can create dangerous glare that disorients the captain.
To check for sectoral lighting, you can use a simple method: when you're on the bridge or steering chair, ask the assistant to turn on the lights in turn. You should not see the light source on the port side while on the right side, and vice versa. The top light should be visible in the sector from the nose to 22.5 degrees per traves, but should not blind the observer.
How to make a screen yourself?
The screen can be made of sheet aluminum or solid plastic, painted with black matte paint. The shape of the screen must exactly follow the arc of the sector, cutting off the light outside.
Equipment selection: LEDs against incandescent lamps
The modern market of navigation equipment offers two main types of light sources: traditional incandescent lamps and LED (LED) lamps.LED) Modules: Incandescent lamps, although a thing of the past, are still found on older boats, with the advantage of being low cost and easy to replace, but they consume more energy, are highly heated and have a short lifespan.
LED lights are devoid of these drawbacks, they consume minimal energy, which is critical for autonomous swimming, where the count goes on battery ampere hours. LED cells have a lifespan of tens of thousands of hours, making them virtually unmaintainable, and they also reach full brightness instantly and are less sensitive to vibration.
However, when choosing LEDs, it is important to pay attention to the quality of execution and the availability of certificates of conformity. Cheap Chinese counterparts may not provide the declared range of visibility or have the wrong color hue, which is a violation of the rules. Certified lights undergo rigorous tests for color temperature and angle of dispersion.
The transition to LED navigation lighting is an investment in safety and energy efficiency, reducing the load on the vessel’s battery system.
When replacing lamp lights with LEDs, it is important to note that some older blinking relays or control systems may not work properly with low-voltage LED loads, in which case additional resistors may be required or relays may be replaced with LED-compatible ones.
Service and preparation for the season
The reliable operation of navigation lights requires regular maintenance, before each exit in the season, you must conduct a visual inspection of all elements of the system, check the housings of lights for cracks, chips or signs of clouding, which can reduce the intensity of the light signal.
Pay special attention to contacts and sockets. Even in sealed housings, moisture can condense over time, causing oxidation of contacts. It is recommended to periodically disassemble the plafons, clean the contacts with fine sandpaper or special spray for contacts and lubricate the threaded joints with silicone lubrication to prevent fretting.
Remember to check the lights not only visually, but also by measuring the voltage at the terminals. A voltage drop may indicate problems in wiring or battery discharge. Regularly check that in a critical situation your light alarm will work faultlessly.
The storage of lights in winter also has its own peculiarities: the removed lights are better stored in a dry room at room temperature, packing them in soft fabric or original packaging to avoid mechanical damage and exposure to temperature changes.
What is the minimum height of the top fire installation?
For vessels less than 12 metres in length, the minimum height of the masthead light above the hull is not strictly regulated, but it must be set above the side lights by at least 1 metre. For larger vessels, the height is calculated by the formula depending on the width of the vessel, but is usually at least 2.5 metres above the deck.
Can I use one light instead of two?
Yes, for vessels less than 12 metres in length, one combined diametrical lantern is allowed, which shines green to the right and red to the left, but the classic scheme with separate lights is preferable for better visibility from different angles.
What if one of the lights is burned out on the way?
According to the regulations, if a navigation light is out of order, the skipper must immediately restore it or replace it with a replacement one. If this is not possible, appropriate signs must be displayed during the day or alternative means of signalling (lanterns, torches) to indicate his presence and, if possible, stop movement or move with extreme caution.
Do I need to register the installed lights in GIMS?
Navigation lights as equipment do not require separate registration, however, changes in the design of the vessel related to the installation of masts or fixed structures for lights may require changes to the boat's ticket if this affects the dimensions or stability of the vessel. In most cases, replacing lamps with LEDs at the regular registration points does not require.
