Do I Need Flares for My Boat?

Boating Flares and Distress Signals

Flare TypesAll boat owners are legally required to meet minimum safety standards, even if they only use it for recreation.

If your boat is less than 16 feet you only need distress signals between sunset and sunrise. This can be one electric distress light or three combination day/night red flares. If your boat is longer than 16 feet, you are required to have one electric distress light and one orange distress flag – OR – one electric distress light and three hand-held or  floating orange smoke signals – OR – three combination day/night red flares.

As a boat owner, you may be too excited to get out on the water to think much about the hazards you might encounter, but those hazards are very real. In some cases, they can be deadly. While government oversight can be a pain, those safety requirements exist for for our own good. Whenever we do anything outdoors and especially around water, it’s best to remember the following motto: Be prepared! So, what exactly are we required to carry on board of our recreational boat? Well, it depends on a few things. Here is a list of what you need to consider before your boat is ready to hit the waves.

The Requirements

Visual distress signals (VDSs) are designed so that boaters can signal for help if they are in distress and unable to save themselves. Under U.S. law, all boats must be equipped with VDSs while operating on coastal waters, the Great Lakes, the territorial or high seas, and any other connecting body of water that is more than two miles wide. Your state might have additional laws, so you should always double-check to make sure you are in compliance with every law that applies to you and your boat. The federal requirements are as follows:

For boats under 16′ in length: Distress signals are only required if the boat is operating between sunset and sunrise. During this time, one electric distress light or three combination day/night red flares are required.

For boats 16′ in length or greater:

  • One orange distress flag and one electric distress light OR
  • Three hand-held or floating orange smoke signals and one electric distress light OR
  • Three red flares for combined day/night use, which can be handheld, meteor or parachute type

If your boat is over 16 feet, you must carry VDSs. The exceptions to this requirement are:

  • Vessels on lakes (except the Great Lakes)
  • Sailboats under 26 feet that do NOT have propulsion machinery
  • Manually propelled boats
  • Boats participating in organized events

For the above vessels, VDSs aren’t required. Non-pyrotechnic devices and electric distress lights may also be acceptable under certain situations.

Types of Visual Distress Signals

Marine Flare VDSA diverse range of signaling devices can be carried onboard to meet the legal requirement for VDSs. There are two general types: pyrotechnic and non-pyrotechnic. Besides recreational boats less than 16 feet, all other boats must carry both night and day signaling devices. Any combination can be carried as long as they add up to three signals for day use and three signals for night use. Having three VDSs designed for both day and night use meets both requirements.

The following combinations of distress signals can be used to satisfy the VDS law:

  • Three hand-held red flares (for dual daytime and nighttime use)
  • One hand-held red flare and two parachute flares (daytime and nightime use)
  • One hand-held orange smoke signal (daytime use)l, two floating orange smoke signals (daytime use) and one electric distress light (nighttime use only)

Note: If you opt for a pyrotechnic VDS, a minimum of three have to be carried onboard. Pyrotechnic devices come with an expiration date. Usually, it’s 42 months from the date of manufacture. To meet carriage requirements, you must have at least three un-expired flares aboard. You can choose to carry expired flares as backup, but they won’t count towards the legal requirement.

Pyrotechnic Visual Distress Signaling Devices

These types must be Coast Guard-approved, in good working condition, and stowed in an accessible place. If they are marked with an expiration date, this date must not have passed. Launchers produced before Jan. 1, 1981, intended for use with approved signals aren’t required to be Coast Guard Approved.

USCG Approved Pyrotechnic Visual Distress Signals and Associated Devices include:

  • Pyrotechnic red flares, handheld or aerial
  • Pyrotechnic orange smoke, hand held or floating
  • Launchers for aerial red meteors or parachute flares

The purpose of this rule is to make sure that boaters have a way of attracting attention and getting help if they ever find themselves in an emergency. When used the right way, VDSs will also help reduce the time it takes to find a boat during a search. This lessens the possibility of a minor emergency becoming a tragedy.

Non-pyrotechnic Visual Distress Signaling Devices

This type must carry the manufacturer’s certification that they meet Coast Guard requirements. They must be in good working order and stowed to be readily accessible. This group includes:

  • Orange distress flag
  • Electronic distress light

Types of VDSs for Daytime Use Only

Handheld orange smoke distress signals:

Hand held distress signals are very common. Make sure to hold the flare with a glove, and make sure to keep the smoke downwind of your boat.

Floating Orange Smoke Distress Signals

These come in two varieties. There is one that last 5 minutes and another that lasts 15 minutes.

Orange Distress Signal Flag for Boats

The distress flag must be at least 3 x 3 feet with a black square and ball on an orange background. It is accepted as a day signal only and is especially effective in bright sunlight. The flag is most distinctive when waved on something such as a paddle or a boat hook or flown from a mast.

Sea-marker Dye

Sea-marker DyeThis is useful when air search is underway. The dye is available in several different colors and should be used when chances of being spotted are high.

Signal Mirror

Although not recognized by USCG as a carriage requirement, a well-handled signal mirror can be very effective in calling attention to oneself. It is low in cost and has an unlimited shelf life.

The handheld and the floating orange smoke signaling devices are excellent (if not the best) day signals, especially on clear days. Both signals are most effective with light to moderate winds. However, in higher winds the winds tend to disperse the orange signal cloud which makes it harder to see.

Types of VDSs for Nighttime Use Only

SOS Electric Distress Light for Boats

The electric distress light must automatically flash the international SOS distress signal, which is known to most boaters all over the world. The SOS Distress Light meets U.S. Coast Guard requirements and can replace traditional pyrotechnic flares. Unlike traditional flares, this electronic flare never expires, eliminating any worries you might have related to disposing expired flares. The LED light flashes only the SOS sequence which is in accordance with USCG requirements. It can be visible up to 10 nautical miles away for up to 60 hours, compared to a traditional flare that can last for a minute or less.

NOTE: An ordinary flashlight is not acceptable as a distress light. The flashes have to be operated by hand, and their power is comparatively weak.

Anytime Use

Some of the following may need to be used in combination with a suitable launching device:

  • Handheld Flare Distress Signal
  • Parachute Red Flare Distress Signals (25 mm or larger)
  • Handheld Rocket-Propelled Parachute Red Flare Distress Signals
  • Red Aerial Distress Signal for Boats
  • Pyrotechnic Flare (either meteor or parachute-assisted)

No one single signaling device is ideal under all conditions and for all purposes. Therefore, you might want to think about carrying a few different types. For example, an aerial flare can be seen over a long distance on a clear night. But for closer work, a handheld flare might be better.

Flare FAQs

What type of flares do I need?

There are many types of flares that you can choose from depending on your boating habits.

Inland Boating:

If you seldom leave sight of land, you should carry:

  • Handheld red flares AND/OR
  • Aerial Flares, such as 12-gauge HP or Skyblazer XLT Signals

Coastal Boating:

If you travel offshore occasionally and you don’t stay out overnight, you should carry:

  • Handheld red flares AND
  • Aerial Flares, such as 12-gauge HP or Skyblazer XLT Signals AND
  • Smoke Flares, such as an orange handheld

Offshore Boating:

If you travel offshore occasionally and you don’t stay out overnight, you should carry:

  • Handheld Flares: SOLAS Approved AND
  • Aerial Flares: 25MM or SOLAS Approved AND
  • Smoke Flares: Floating SOLAS Approved

How do I know if a flare meets the Coast Guard requirements?

Only visual signals marked with a U.S. Coast Guard approval or certification number meet the Coast Guard requirements.

Since I am covered by the requirement, how many signals do I need to carry?

If you decide to use pyrotechnic signals to meet the Coast Guard VDS requirements, a minimum of three must be carried. Any combination of the signals can be carried as long as they add up to three signals for day use and three signals for night use. Remember that while three signals are the legal minimum, search and rescue experts recommend carrying at least six signals onboard.

Will my flares expire?

Pyrotechnic signaling devices (including aerial flares and hand held signals) expire 42 months after the date of manufacture, which complies with Coast Guard guidelines. Typically, this means that you must replace your flares every three boating seasons. Remember to check your fire extinguishers because they have a limited shelf life too.

Which flare is right for me?

All distress signaling devices have both advantages and disadvantages. The most popular are probably the smaller pyrotechnic devices because of their relatively low cost. They make excellent distress signals because of their visibility, but they can be used only once. Additionally, they can be hazardous if not properly handled. Pyrotechnics devices have a very hot flame which can cause burns and ignite flammable material, such as clothing. Projected devices are very similar to traditional firearms and should be handled with the same caution. The very best flares available in terms of brightness and duration are labeled SOLAS. SOLAS-marked flares go above and beyond US Coast Guard minimums.
