What is the visibility in navigation?

Knowing how far you can see a navigational light—or when it will fade from view—is crucial, especially when approaching land. Here’s how visibility is categorized:

Luminous Range: This is the max distance where you can spot a light based on current weather conditions. It’s like the light’s “stage presence,” but it doesn’t factor in elevation, your eye level, or Earth’s curve.
Atmospheric Influence: Ever wonder why some lights seem to vanish or appear out of the blue? Blame it on the atmosphere—it’s the ultimate light filter, affecting how far a light can travel.

So, when you’re navigating, remember that light visibility isn’t just about the light itself; it’s a performance featuring the light, the weather, and the atmosphere.

Meteorological Optical Range Table
Code No.	Weather	Distance (m)	Code No.	Weather	Distance (NM)
0	Dense fog	Less than 50	5	Haze	1 – 2
1	Thick fog	50 – 200	6	Light haze	2 – 5½
2	Moderate	200 – 500	7	Clear	5½ – 11
3	Light fog	500 – 1000	8	Very clear	11 – 27
4	Thin fog	1000 – 2000	9	Exceptionally clear	Over 27

The international standards for describing reduced visibility in marine forecasts are as follows:
Very Poor: <0.5 NM
Poor: 0.5 – 2 NM
Moderate: 2 – 5 NM
Good: >5 NM

Can You Read the Language of Flashing Lights?

The language of flashing lights is a specialized form of communication used primarily in maritime and aviation settings. These specific flash patterns help to identify the type and purpose of lights, serving as a crucial element for navigation and safety.

IALA Words

Navigational aids, or “navaids,” are your go-to landmarks at sea, like lighthouses and buoys, making your maritime journey safer by giving you more ways to find your Lines of Position (LOPs). Don’t confuse these with gadgets like GPS or compasses; they’re in a league of their own. Thanks to the International Association of Lighthouse Authorities (IALA), the world is divided into two buoyage playgrounds: Region A for Europe and most places, and Region B for the Americas and some parts of Asia. The good news? The rules are almost the same, with just a twist in the buoyage direction.

By day, you’ll spot navigational aids by their location, shape, color scheme, and any extra bells and whistles like sound signals or RACON.
Come nightfall, to identify an Aid to Navigation (AtoN) and figure out what it’s telling you, focus on three key light features.

Colors in navaid lights range from white, red, and green to yellow, orange, and blue.
The “period” refers to the time for one full cycle of light changes, usually between 3-10 seconds. For example, a “Fl (2) 10s” light means two flashes in a 10-second period, including 8 seconds of darkness.
The “phase characteristic” describes the light’s pattern within one cycle. Generally, faster changes signal greater danger.

Abbreviation	Class of light	Illustration / description
F	Fixed	This light is the strong, silent type—always on, never blinking, and steady as a rock. Take a yellow fixed light, often labeled as “F Y,” for instance
Occulting: total duration of light longer than total duration of darkness.
Oc	Single-occulting	Occulting is the opposite of flashing; the light is more on than off.
Oc (x)	Group-occulting	This example shows Oc (2).
Oc (x+y)	Composite group-occulting	This example shows Oc (2+3).
Isophase: duration of light and darkness equal.
Iso	Isophase
Flashing: less than 50 per minute, and total duration of light shorter than total duration of darkness.
Fl	Single-flashing
Fl (x)	Group-flashing	This example has three flashes grouped per period: Fl (3)
Fl (x+y)	Composite group-flashing	A combination of two patterns in one period. In this example the first 2 flashes followed by the pattern of 3 flashes result in: Fl (2+1)
LFl	Long-flashing	This light has one long flash (2 seconds or longer) in a period.
Quick: repetition rate of 50 to 79 – usually either 50 or 60 – flashes per minute.
Q	Continuous quick
Q (x)	Group quick	This example shows a Q (3) light.
IQ	Interrupted quick
Very quick: repetition rate of 80 to 159 – usually either 100 or 120 – flashes per minute.
VQ	Continuous very quick
VQ (x)	Group very quick	This example shows a VQ (3) light.
IVQ	Interrupted very quick
Ultra quick: repetition rate of 160 or more – usually either 240 to 300 – flashes per minute.
UQ	Continuous ultra quick
IUQ	Interrupted ultra quick
Mo (x)	Morse code	A combination of flashes and long-flashes equivalent to Morse code, in this example the letter “A”: Mo (A), which is often used to indicate safe water.
F Fl	Fixed and flashing
Al xy	Alternating	In this example Al WG is shown, alternating between green and white. This special purpose light is typically used for special applications requiring the exercise of great caution.

Typical lights with colour, period and phase characteristics:

LFL 10s

Q(3) G 9s

Iso 6s

F Fl Y 5s

Oc 5s

Al WR 4s

Mo (U) 8s

How to set up navigation lights for different applications?

Navigating the maritime world requires a keen understanding of various buoy types and their corresponding lights.

Here’s a quick guide to help you sail through:

Type 1 - Lateral marks – direction of buoyage

Light Color: Red or Green
Purpose: To indicate the port (left) and starboard (right) sides of navigable channels.

Red buoys sport red lights, and green ones go with green lights—no mix-and-match here. But keep an eye out for the unique “group flashing FL (2+1)” pattern; that’s the VIP signal exclusive to preferred channel buoys.

Type 2 - Cardinal marks

Light Color: White, with a specific flashing sequence (North, South, East, West)
Purpose: To indicate the safest direction to pass an obstacle.

Type 3 - Isolated Danger Buoys

Light Color: White, with a group flashing pattern (Fl (2))
Purpose: To mark small, isolated hazards.

Light: white Fl(2).

e.g. Fl (2) 8s
can be any period, yet always white.

Type 4 - Safe Water Buoys

Light Color: White, with a long flash every 10 seconds (L Fl 10s)
Purpose: To indicate safe, navigable waters.

Type 5 - New danger mark

Purpose: To mark new wrecks that pose a navigational risk.
Light Color: Yellow and blue, with a yellow light flashing once every 4 seconds (Fl Y 4s)

Topmark: a standing / upright yellow cross.

Light: Al Oc Bu Y 3s
Blue 1.0s + 0.5s + Yellow 1.0s + 0.5s = 3.0s

If multiple buoys are deployed then the lights will be synchronized.
A racon Morse Code “D” and / or AIS transponder can be used.

Type 6 - Special mark

Light Color: Yellow,for instance Fl Y or Fl(4) Y but any rhythm other than those used for white lights on cardinal, isolated danger or safe water marks.
Purpose: To indicate a special area or feature, such as fishing zones or diving areas.
