Slow lights on the boat: how to stand by the rules and GOST

The safety of navigation on a small vessel depends on its visibility to other participants in the movement, especially in the dark or with limited visibility. Side lights They are not just decorative tuning, but critical navigation equipment that allows you to determine the course, size and status of the vessel. Incorrect installation can lead not only to a fine from the GIMS, but also to an emergency situation on the water.

In this article, we will discuss in detail how running lights should stand on a boat according to the current regulations, what are the requirements for their height and visibility angles. You will learn about the differences in the equipment of boats less than 7 meters long and larger boats, as well as the technical nuances of installation of LED systems. Rules for navigation on inland waterways (VVWP) The rules clearly regulate every aspect, the neglect of which is unacceptable for the responsible boat owner.

The correct positioning of the light sources provides a clear understanding of your situation by other captains, if the lights are random or have the wrong color, it disorients others and increases the risk of collision. lighting It should be approached with the utmost care even at the stage of designing or upgrading the boat.

Regulatory framework and classification of boats

The main document regulating the equipment of navigation lights in Russia are: PVDPV (Inland waterways regulations) For small craft, which include PVC boats, boats and yachts, requirements may vary depending on the length of the hull and engine type. It is important to understand that the law divides boats into categories, and there are exceptions and mandatory rules for each.

Vessels less than 7 metres long and with a speed of no more than 7 knots have simplified requirements, but even for small boats, having at least one white light of circular visibility is mandatory when driving at night. sidelight and top-of-the-line fire.

⚠️ Attention: The absence of navigation lights or their improper operation is equivalent to a failure of the steering and is the basis for the prohibition of the operation of the vessel by the inspector of the GIMS.

When determining the category of your vessel, it is not only the length of the documents that counts, but also the actual load capacity and engine power. If you have installed a motor that is more powerful than the design, the requirements for lights may change. small-boat and the current version of the rules.

Lamp layout for boats up to 7 meters

For most owners of inflatable boats and small boats, the scheme for vessels less than 7 meters long is relevant, in which case a combined installation is allowed, which simplifies installation and reduces equipment costs. The basic principle is to ensure the visibility of the vessel from the front, rear and from the sides.

A combined light is usually installed on the bow of a boat, which combines red (left side) and green (right side) colors, as well as a white masthead light. However, for small craft, an alternative is often used: one white light of circular visibility, located so that it is visible from all directions, which simplifies the task, but requires compliance with the height of the installation.

If you use separate side lights, they should be closer to the bow than the stern light, the red light should always be placed on the left side, the green light should be placed on the right side, and this arrangement is universal for all types of boats and allows other captains to instantly read your course relative to their own position.

• 🔴 A red light should be installed on the port side and illuminate the sector from the nose to 22.5 degrees behind the traversal.
• 🟢 A green light shall be placed on the starboard side with a similar sector of illumination to the right of the diametric plane.
• ⚪ The white aft light should illuminate a sector of 135 degrees, directed back from the stern.
• 🔦 The top light (if required separately) is placed in the diametric plane and shines 225 degrees in the front sector.

Height of fire above water should be sufficient for visibility, but not excessive, so as not to disturb the stability and dimensions.

Requirements for vessels longer than 7 metres

For larger boats and yachts that are longer than 7 meters, or vessels that are faster than 7 knots, the scheme becomes more complex and closer to the requirements for larger boats, and it is no longer acceptable to use a single combined light if it does not provide the required lighting sectors without shading the vessel's structures.

Top fire If the vessel has two masthead lights, the rear light shall be at least 1 meter above the front light, and the horizontal distance between them shall also be regulated and shall be at least half the length of the vessel, but not less than 2 meters.

The onboard lights on large vessels shall be installed at least 1 metre from the diametric plane, if possible structurally, so that when viewed from another vessel at an acute angle, one side does not obstruct the other, creating a false impression of the course.

Type of fire	Colour	Sector of visibility	Minimum range (mile)
Top-of-the-line	White	225° (front)	2 (for boats < 12m)
board-board	Red/Green	112.5° (board)	1 (for boats < 12m)
Aft-handed	White	135° (back)	2 (for boats < 12m)
Circular	White	360°	2 (for boats < 12m)

Particular attention should be paid to the height of the lights above the hull, the top light should rise above the hull by at least 1 meter, and if there are two, the rear should be higher than the front one, which ensures the visibility of fire above the superstructures, cabins and passengers' heads.

Visibility angles and lighting sectors

Understanding the lighting sectors is a key to proper installation: each light should be visible only in a certain sector of the horizon, and breaking these boundaries, for example when a red light is visible on the starboard side, is a grave mistake that misleads other boatmasters.

The lights on the side of the plane must have shields that prevent light from reaching the opposite side, and if you use a navigation light, they already have built-in screens. custom-set from LED modules, you need to independently manufacture and install opaque partitions.

How to check the lighting sector at home?

Place the boat on a flat surface. Stand straight on the bow of the boat at a distance of 5-10 meters. You should see both red and green lights (or white top lights). Move to the right 45 degrees - the red light should disappear, only green will remain. Move to the left - vice versa. Behind the boat, the side lights should not be visible at all.

The aft light illuminates a sector of 135 degrees symmetrically distributed on either side of the stern diametrical plane, which means it must be visible from the perpendicular traversal position to 22.5 degrees per traversal position on each side. Accurately adjusting the direction of the light is critical.

Technical requirements for light sources

The modern market offers many solutions, from classic incandescent lamps to powerful ones. LED modulesFor boats, LEDs are preferable, as they consume less energy, which is important for autonomous batteries, and have high vibration resistance.

All lights must meet chromaticity requirements: white light must not be yellowish or bluish, red and green must be saturated and comply with the CIE (International Commission on Lighting) standard. Using cheap Chinese diodes can lead to the color being misidentified.

• 💡 LEDs should have a Protection rating not lower than IP67better. IP68Because water is constantly exposed to moisture and splashes.
• 🔋 When choosing power, consider battery capacity; LED lights consume 5-10 times less energy than incandescent lamps.
• 🛡️ Lamp cases should be made of materials: stainless steel, brass or high-quality plastic.

An important aspect is the lack of flickering. Cheap LED drivers can give a ripple that tires the eyes and may be misunderstood by other observers as an alarm. Choose proven brands of sea light, such as: Hella, AquaSignal or MarineLED.

⚠️ Warning: Never use colorful RGB tapes with remote control as the primary lights for navigation lights, and their color can be changed by accident, which will lead to violation of the rules and create a dangerous situation.

Installation and connection of electrical equipment

Putting lights on a boat requires a smart approach to wiring. Water and electricity are a dangerous combination, so all connections must be sealed. Use shrink tubes with adhesive layers and special sea terminals coated with tin or silver to protect against corrosion.

Wiring should be laid inside the housing or under protective boxes to prevent mechanical damage and exposure to ultraviolet lights, a dedicated line with a separate fuse located in an accessible place at the control panel is recommended to power the lights.

If the boat is metal, make sure that the luminaire housings do not create a galvanic pair with the hull, which can accelerate corrosion. In such cases, the installation of dielectric gaskets is mandatory. For wooden and PVC boats, this risk is minimal, but moisture protection remains the #1 priority.

After installation, be sure to test the system with the outside lights off. Check the operation of each light separately, make sure that there are no closures on the body and the polarity of the connection is correct. Electrical reliability It is a guarantee that you will not be left in the dark at a critical moment.

Frequent Installation Errors and How to Avoid Them

One of the most common mistakes is to set the lights too low, so when passengers are in the boat, their heads and backs block the lights, making the boat invisible to others, and the lights must be raised to a sufficient height, as required by the rules.

Another mistake is the wrong centering, and if the top light is sideways shifted rather than diametrically, it distorts the view of the vessel's course for the observer in front, and it's also common to confuse left and right when mounting the side lights, which is a fatal mistake.

Some owners neglect glare protection, light reflected from the inner surfaces of the boat, glass or water, can blind the helmsman, reducing his night vision, lights should be directed strictly outwards and have visors to prevent light from entering the eyes of the crew.

Can a single combined fire be used for a boat up to 7 meters?

Yes, for boats less than 7 metres long, the rules allow for the use of a single combined light that combines the functions of the side and top lights, or the installation of a single white light of circular visibility in combination with the side lights if the vessel is on the move.

How high should a top fire be?

For vessels less than 12 metres in length, the masthead light must be at least 1 metre above the hull. If the vessel has two masthead lights, the rear light must be at least 1 metre above the front. The exact values may depend on the width of the vessel, but the 1 metre rule is the base minimum.

Do I need to register the installed lights in GIMS?

Navigation lights do not require separate registration by themselves, but when undergoing an annual technical inspection, the GIMS inspector will check their availability, serviceability and correctness of installation, and the failure of the lights to comply with the rules will cause a remedial order to be issued.

What to do if the LED fire burns out on the water?

The rules require that there be spare light sources on board or the ability to quickly replace a burnt out element. For LED systems, it is recommended to carry a ready-made spare light or a set of LEDs with connectors for quick replacement, so as not to violate the rules of swimming at night.

Is it allowed to use flashing lights?

No, the use of flashing navigation lights for ordinary boats is strictly prohibited, as it can be perceived as a distress signal or a special signal. Navigation lights must be lit with a constant, even light. Only special signal lights, the use of which is strictly regulated, can flash.
