What Does a Diver Down Flag Look Like?

Safety is the top concern when engaging in scuba diving. Boat traffic above the water’s surface while divers are present is one of the dangers to be aware of.

Boat traffic can also be noisy if it isn’t going too deep, but if it is coming to the surface, it could be an issue and lead to a collision.

You run the risk of being run over by the boat. The diver down flags are used to alert passing boats that divers are in the area as a solution.

You must be familiar with the many sorts of diver down flags as well as how they appear.

Diver down flag types:

Two different types of flags are employed to indicate when diving is occurring.

As a general guideline, I advise flying both flags to make sure you have all of your bases covered. Both flags have essentially the same significance and may therefore be used interchangeably.

1.The Traditional Red and White Flag

The accepted recreational dive flag is the traditional flag, and it is primarily recognized in the US, Canada, and any other countries that follow US diving traditions, such as the Caribbean countries.

It is crimson with a white line running across it diagonally. In the water, it is used to signify nearby snorkeling and scuba diving activity. A well-known scuba diving flag is the red and white dive down flag.

It was developed in 1956 by a Navy officer named Denzel James Dockery, and it rose to reputation as a result of the US Navy’s widespread use of it.

2.International Maritime Signal Alpha Flag (Alfa)

The blue and white flag is another diver down flag to be aware of. This alpha flag is frequently used around the world to denote that a boat or other vessels has divers on board.

This indicates that the boat’s mobility is limited and that other boats should maintain a safe distance and slow down. While the red and white diver flag is primarily used to protect the real divers, this alpha flag serves to safeguard the boat from collisions.

The Alpha flag’s primary purpose is to stop other vessels from colliding with the divers’ vessel or other adjacent ships, even if it also helps warn ships of the presence of divers below.

Considering that they would have slowed down, collisions are more likely.

A well-known flag is the Alpha flag, which also stands for the letter A in the flag alphabet. The mast side is composed of a white rectangle with a blue rectangle outside that is notched.

All countries fly this blue and white flag; the USA and Canada are the notable exceptions.

Surface Marker Buoy (SMB)

A surface marking buoy is a third, more particular usage marker (commonly referred to as an SMB). Another name is Surface Location Marker.

It is a marker intended to help precisely pinpoint a diver’s location for pickup, not a dive “flag” meant to communicate with outside parties.

Actually, a dive flag is more of a generic signal for nearby boat traffic, whereas an SMB is a more precise pinpoint of where a specific diver is.

Divers bring deflated surface markers with them on their dive and inflate them when it’s time to be picked up in order to communicate their location to the diving boat.

Since you often don’t return to where you left off to join the boat, drift diving is the greatest circumstance in which to employ this type of marker.

SMBs are often long, narrow, cylindrical objects that are neon yellow or orange in color.

These are the features that you need to pay attention to when choosing a diver’s flag:

1. Size

If the flag is going to be flown from a buoy or floating platform, it must be at least 12 by 12 inches in size. On the other hand, if you want to display it on a vessel or any larger design, the minimum size required is 20 inches by 24 inches.

This applies to the red, white, and blue, as well as the white and blue flags.

The flag must be large enough for someone to observe it from a safe distance before moving after seeing it.

2. Materials’ quality

The fabric of your scuba flag, along with any additional items to which it is connected, must be strong enough to withstand both the weather and the choppy water.

In order to prevent corrosion, the other components, especially the metal ones, should be corrosion resistant, and the nylon should be at least 200D.

The colors of the buoy and flag must also be durable enough to last throughout the flag’s use and attractive enough to be seen from a distance. Nylon and other colored materials should be used for this instead of dyed ones.

The flag must remain stiff at all times. This necessitates a stiffener that is impervious to weather-related cracking or buckling.

3. Stability

If you have a decent diver’s flag and float mechanism with an unstable base, the flag’s purpose is eliminated because it can collapse over and put you in danger from other water users.

As required by law, the flag must always be flown upright. The point of attachment must be strong since the flag needs to be able to remain fastened to the buoy even during a storm.

4. Ease of use

Numerous flag and float combinations are conceivable. Whatever you decide, the layout should be usable. In this context, the terms “gear setup” and “gear storage” are used interchangeably.

It was easy to work with the vast majority of designs that used collapsible typefaces. They should be small and lightweight so that they are even simpler to carry and move around.

5. Accessories

The flag and float procedure might be improved, for example, by adding a provision allowing the flying of a new flag in the event that the current one breaks or becomes too large in accordance with the law.

Additionally, it should be able to connect to your diving gear so you can securely float while keeping it aloft.

What does a diver down flag look like, FAQ

When should the diver down flags be raised?

divers flag

Dive down flags are used to signal to passing vessels that you have a diver down. That a diver is present underwater is not implied.
Furthermore, it signifies that the dive boat has restricted maneuverability and that other vessels must make way.

How far should boats stay away from a diver downing flags?

Boats that aren’t diving should keep a safe 60 meters or more away from the diving area where the flag is flown.

What to do if a diver down flag Is flying while you are boating?

Maintain a distance of at least 25 meters from any visible diver-down flag if you are boating and you notice one.

What is the appearance of a diver down flag?

divers flag 2

An undersea diver is down when there is a Diver Down Flag. This alerts boaters to avoid getting too close, protecting the diver from the boat and propeller as they descend or as they ascend from a dive.
When divers are in the water, the diver down flag needs to be flown from a boat or a buoy.
The flag should be flown from the highest point of a vessel and should measure at least 20 inches by 24 inches. The diver down flag should be at least 12 inches by 12 inches when it is tied to a buoy.

What is required of scuba divers in their dive location?

alfa flag

When there are divers present, they should only fly the diver down flag. You must presume that boaters and others on the surface are unaware that you are underwater when you are a scuba diver.
Using a diver down flag requires scuba divers to follow certain guidelines.
Divers must keep within a hundred feet (thirty meters) of the flag when diving in rivers, inlets, or navigation channels, or within three hundred feet (ninety meters) of the flag when diving in open water, according to the Diver’s Alert Network (DAN).
The diver down flag should be within one hundred fifty feet (forty-five meters) of the diver ascent target.
But always double-check your local laws because they can be different.
A diver should keep within fifty feet (fifteen meters) of your flag and shouldn’t ascend higher than twenty-five feet (almost seven meters) from the flag, according to the usual rule of thumb.
A diver down flag should only ever be flown when there is genuine scuba diving or snorkeling activity taking place in the water.
Additionally, be careful not to dive or fly the flag in a channel or area with a lot of boat activity.

When is snorkeling or scuba diving indicated?

These two distinct diver down flags designate locations where both scuba diving and snorkeling are allowed.
This is important because it stands to reason that a place that is great for snorkeling or scuba diving will likely also be great for another activities such as wakeboarding, jet skiing, or parasailing.
Due to their rapid movement, they sometimes missed the typical indicators of scuba diving or snorkeling. This necessitates the use of a dive flag.
Other signs of scuba diving include lights glowing underwater, water with bubbles, or the use of a surface marker buoy.

Is a dive flag required for snorkeling?

Don’t assume that just because you’re snorkeling on the surface, boats and other watercraft can see you. A boat’s captain may frequently become blinded by the sun bouncing off the sea.
The surface may also have waves or ripples that can conceal a snorkeler. When they want to check out anything underwater while remaining hidden from view, snorkelers will occasionally duck dive down a few meters or feet.
This is why it’s crucial to use a diver down flag while snorkeling, both in the sea and on the boat/vessel.
For snorkeling, the same flags that are used for scuba diving can also be utilized.
In Florida, for instance, the law defines “diver” as “a person who is totally or partially immersed in the waters of the State and is equipped with a face mask and snorkel or underwater breathing apparatus.” Swimmers are excluded from this.

What makes a dive flag essential?

You might argue that because divers can go deeper than boats, it doesn’t matter if waterway traffic runs over you.
You will probably still hear the boats if you are in mid-dive or deep underwater. At this time, they might be able to safely drive over you.
Although it is noisy, this is absolutely safe if you are deep enough.You are most vulnerable while you are at a shallower depth, starting a dive, or coming back to the surface after a dive.
This is due to the fact that you will be entering the water at the same level as larger boats.

Exactly what does this do for other ships?

If either of these dive flags is flying while you are at sea, you should probably change your course.
You must give the area a wide margin of at least 100 yards if you observe a diver’s down flag. Passing should also be done slowly.

There are two dive-down flags, one of which is recognized globally and the other of which is specific to North America.

The purpose of the flags is to safeguard the diver. They warn and alert passing boats that there are divers in the water, preventing collisions. The diver must also take care to rise slowly and as closely as possible to the diving flag or dive boat.

Divers should never assume that every boat driver is aware of how to utilize diving flags.

These flags should be recognized by all divers and water sports enthusiasts as they protect people and vessels. If one dives without flying one of these flags or another sign, they may be subject to a fine.

One of these flags shouldn’t be placed near a busy intersection. This will be a huge annoyance if you are too close to other divers or in the way of water traffic. By using common sense, you can look for a dive site that is safer and less likely to cause mayhem.
