Night navigation or movement in reduced visibility is not just romance, but a serious challenge for the boatmaster, where safety comes to the fore. navigational lights They are the only way to mark their boat to other traffic participants and avoid a catastrophic collision in the dark, and the lack of a working light alarm equates to driving without headlights on the dead of night, posing a direct threat to the lives of the crew and passengers.
The modern market offers many solutions, from budget Chinese lanterns to professional marine lamps certified to standards. IMO and CEThe owner of a small vessel should not only choose reliable equipment, but also properly install it, observing the angles of visibility and color marking rules. In this article, we will discuss all the nuances that will help you feel confident on the water after sunset.
Beyond the legal obligation to have proper lights according to the GIMS rules, it is a matter of basic navigational culture. top-end, flight and feed The lights allow the captains of other boats to instantly count your situation, whether you are going to meet, cross course or anchor, and a mistake in mounting or choosing a color can be misunderstood by another boatmaster, leading to an incorrect evasion maneuver.
Classification and assignment of running lamps
First, you need to be clear about what kind of lights are required for your type of vessel and what situations they should burn, and the main division is by glow colors and sectors of view, which are strictly regulated by international and domestic collision prevention regulations. Red. The fire is always on the left side, and green The right-hand language, which is a universal maritime language.
The central element of the system is often lamp It's white, visible from the front and from the stern. On small motorboats, it can be combined with a stern in one universal light mounted on a mast or transom, but for boats longer than 12 meters, the height and visibility requirements become more stringent. It's important not to confuse navigation lights with anchor lights, which have their own glowing specifications.
- 🔴 Onboard left: red light, a sector of visibility of 112.5 degrees from the diametric plane to the nose.
- 🟢 Onboard right: green light, sector of visibility 112.5 degrees from the diametric plane to the nose.
- ⚪ Top/Fringe: white light, illuminates the sector at 135 degrees (stern) or 225 degrees (top).
- 🟡 Anchor: White all-world fire, used only in the parking lot.
When choosing equipment, pay attention to the manufacturer's markings. Certified models have a clear separation in the angles of dispersion, which ensures compliance with the norms. Cheap counterparts often sin by having red light "phonet" in the green sector, which can disorient the oncoming boat.
⚠️ Attention: It is strictly forbidden to use homemade color filters (celophane, plastic) on ordinary lights, they quickly burn out, give uneven light and will not be accepted by the inspector of the GIMS when checking documents.
LED or halogen: Choosing a light source
The choice of lighting technology is a question that every boat owner has faced, and incandescent lights have long been the standard, but today they have taken over the absolute dominance of the boat. LEDs (LEDs) They consume minimal current, which is critical for autonomous voyages where battery capacity is limited.
Halogen lamps, although cheaper to buy, create high heat loads and consume significant current. In addition, the incandescent filament is extremely sensitive to vibration, which is abundant in water. LED modules They are vibration-resistant, have a life of tens of thousands of hours and are often equipped with built-in drivers that stabilize the voltage.
However, when buying LEDs, it is important to consider the build quality. Cheap Chinese diodes can quickly degrade under the influence of ultraviolet and salt water, losing brightness. Quality marine lamps have a sealed housing with a protection class of no lower than the lower. IP67 or IP68 And lenses made of polycarbonate that is resistant to clouding.
- 💡 Energy consumption: LEDs consume 5-8 times less energy than halogen.
- ⏳ Resource: LEDs last for years, incandescent lamps require a constant supply.
- 🌊 Leakproofness: High-quality LED lights are better protected from condensation inside the housing.
When replacing halogen lights with LEDs, make sure that there is no relay with a minimum current threshold in the circuit, otherwise the LEDs may not catch fire or start flickering, in which case you need to replace the relay or install trick resistors.
GIMS requirements and installation rules
Installation of navigation lights is not just a creative process, but a strictly regulated procedure.MPPSS-72) Not only do the lights have to be placed in the water, but they also have to be placed in the water, and if they are not, they can result in fines and, worse, in an emergency.
The height of the top light above the water must be at least 2.5 meters for boats less than 12 meters long. The onboard lights are set below the top light, but not less than 1 meter above the deck. The aft light also has its height restrictions. Ignoring these parameters can lead to your vessel being misidentified from a long distance.
The table below shows the basic requirements for motorized vessels less than 12 meters long, which are most popular among amateurs:
| Type of fire | Colour | Min. range of visibility | Viewing angle |
|---|---|---|---|
| Top-of-the-line | White | 2 miles | 225° |
| Onboard (left) | Red. | 1 mile | 112,5° |
| Onboard (right) | Green. | 1 mile | 112,5° |
| Aft-handed | White | 2 miles | 135° |
If you install a mast for a top-end fire, make sure it's rigidly fixed and won't tilt under the weight of the fixture when pitching. PVC There are special flexible masts that are safe in case of accidental impact.
⚠️ Attention: On boats less than 7 metres long and with a maximum speed of less than 7 knots, the rules can be relaxed: one white light is allowed, which must be visible from all sides.
Connection scheme and electrical part
Installation of wiring on a boat requires a different approach than the car. Moisture, salt mist and constant vibration are the main enemies of electric circuits. UL BC-5W2 or similar, specifically intended for marine use, with tinted copper veins.
All connections must be made with waterproof terminals, adhesive-layer heat shrinkage or soldering followed by insulation. Swings on water are guaranteed oxidation and loss of contact at the most inopportune time. switch-off or safety locks for each group of lamps not more than 45 cm from the power supply.
Connection diagram:[Battery (+)] --> [Main Mass Switch] --> [Distribution Panel]
[Distribution panel] --> [Fuse 5A] --> [Fuse switch for masthead light] --> [Fire]
[Distribution panel] --> [Fuse 5A] --> [Switch of side lights] --> [Lights]
Don't forget to ground (minus wire) it should be no less cross-sectional than the plus wire. Lay the cable in a corrugated tube if it passes through open areas to protect the insulation from rubbing against the sharp edges of fiberglass or aluminum.
☑️ Checking electrical wiring
Nuances for different types of housing
Installation of lights aluminum and fiberglass In the case of metal, it is critical to avoid electrochemical corrosion. If you use lamps with brass or bronze elements, direct contact with the aluminum side will cause rapid destruction of the metal. Use plastic sheaths and insulating pads.
For inflatable boats PVC The problem of installation is even more acute in catamarans, and a hard mast is not always appropriate here, often using magnetic base suction cups (for boats with metal bottom) or special inflatable holders, the main requirement is the stability of the structure in the wind and no risk of damage to the cylinders with the sharp part of the fastener.
If you own a hard top boat, the top light is often integrated into the roof of the cabin, in which case you need to ensure that the cable is tightly inserted through fiberglass using special input cables. cable glandsA simple hole filled with sealant will leak sooner or later.
How to protect contacts from salt?
Use a contact spray (e.g., silicone-based) after assembly, which displaces moisture and creates a protective film, preventing oxidation even in aggressive marine environments.
Service and preparation for the season
Navigation lights require minimal but regular maintenance. Before each navigational access, check all lights. Over time, the lenses may become covered with a coating of salt or oxides, which reduces their brightness. Rub them with a soft cloth moistened with fresh water, avoiding aggressive chemicals that can cloud the plastic.
Check the sealing rings on the lamp covers. The rubber tans and cracks over time, losing its tightness. If you notice condensation inside the lamp, immediately disassemble it, dry it and replace the seal. The water inside the LED housing will cause the driver to fail.
- 🧼 Cleanup: Wash the lights with fresh water after each outing.
- 🔧 Puff: Check the attachment of masts and brackets, vibration weakens the bolts.
- 🔋 Contact: Once a season, lubricate the terminals with protective lubricant.
It's also worth checking the status of the switches on the control panel. If they start to "spark" or stick, replace them. The reliability of the lighting system depends on the weakest link in the circuit, and a cheap switch can turn off your lights at the most critical moment.
⚠️ Attention: Never paint a dim lens with paint or paint to restore color, which will disrupt the light distribution and make the fire invisible from a distance, and the cloudy plastic must only be polished or changed.
Regular check of tightness and purity of lenses prolongs the life of lights by 2-3 times and guarantees your safety at night.
Frequently Asked Questions (FAQ)
Can you use one fire instead of three separate fires?
Yes, for motorized vessels less than 12 metres long, the rules allow for one combined (red-green-white) bow light and a separate white stern light, making it easier to install on small boats.
Which battery is best used to power the lights?
It's best to use a separate traction battery or have a backup battery. LEDs don't consume much, but if you leave the main battery empty after a night's parking, you can't start the engine. Deep discharge is bad for starter batteries.
Do I need to register the installed lights in GIMS?
The lights themselves do not need to be registered, but their availability and serviceability will be checked during the annual technical inspection of the vessel, and the absence of lights or their non-compliance with standards will be grounds for a ban on operation.
What to do if one of the lights is turned off?
According to the rules, if one of the side lights is out, the boat must immediately stop moving and try to correct the malfunction, if this is not possible, you need to give audible signals and to identify yourself as much as possible with other available means (lantern, flashes), giving way to all boats.
