Chapter 4: The Legal Requirements of Boating
Visual Distress Signals

Visual Distress Signals (VDSs) allow vessel operators to signal for help in the event of an emergency. VDSs are classified as day signals (visible in bright sunlight), night signals (visible at night), or both day and night signals. VDSs are either pyrotechnic (smoke and flames) or non-pyrotechnic (non-combustible).

VDSs are required to be carried on vessels when on Washington's coastal waters, the Strait of Juan de Fuca east to Puget Sound, and the northern tip of the Kitsap Peninsula at Foul Weather Bluff. All vessels on coastal waters, regardless of length or type, are required to carry night signals when operating between sunset and sunrise. Most vessels must carry day signals also; exceptions to the requirement for day signals are:

• Recreational vessels that are less than 16 feet in length
• Non-power-driven open sailboats that are less than 26 feet in length
• Manually propelled vessels

VDSs must be U.S. Coast Guard–approved, in serviceable condition, and readily accessible.

VDSs are not required to be carried on Washington's inland waters, but they are strongly recommended.

If pyrotechnic VDSs are used, a minimum of three must be carried in the vessel. Also, pyrotechnic VDSs must be dated and will not meet legal requirements past their expiration date.

The following combinations of signals are examples of VDSs that could be carried on board to satisfy U.S. Coast Guard requirements:

• Three handheld red flares (day and night)
• One handheld red flare and two red meteors (day and night)
• One handheld orange smoke signal (day), two floating orange smoke signals (day), and one electric light (night only)

It is prohibited to display visual distress signals while on the water unless assistance is required to prevent immediate or potential danger to persons on board a vessel.

Remember—Even though VDSs are not required on inland waters that are under state control only, they are strongly recommended to be carried on board your vessel. They can be used to alert others of the need for help if you become disabled in a remote area.

Pyrotechnic Devices

• Pyrotechnics are excellent distress signals. However, there is potential for injury and property damage if not handled properly. These devices produce a very hot flame, and the residue can cause burns and ignite flammable materials.
• Pistol-launched and handheld parachute flares and meteors have many characteristics of a firearm and must be handled with caution. In some states, they are considered a firearm and are prohibited from use.
• Pyrotechnic devices should be stored in a cool, dry, and prominently marked location.

Non-Pyrotechnic Visual Distress Signals

Electric Light Night Signal

Orange Flag Day Signal

Arm Signal Although this signal does not meet VDS equipment requirements, wave your arms to summon help if you do not have other distress signals on board.

Non-Pyrotechnic Devices

• The distress flag is a day signal only. It must be at least 3 x 3 feet with a black square and ball on an orange background.
• The electric distress light is accepted for night use only and must flash the international SOS distress signal automatically.

Coastal Waters

Vessels must observe federal requirements on these waters:

• The U.S. waters of the Great Lakes
• The territorial seas of the United States
• Waters (such as bays, sounds, harbors, rivers, inlets, etc.) which are more than two miles wide and are connected directly to one of the above

Sound-Producing Devices

In periods of reduced visibility or whenever a vessel operator needs to signal his or her intentions or position, a sound-producing device is essential. The navigation rules for meeting head-on, crossing, and overtaking situations described in Chapter 3 are examples of when sound signals are required.

• The sound-producing device must be audible for one-half mile.
  • Vessels less than 65.6 feet in length (including PWCs, sailboats, and manually powered vessels) are required to carry on board a mouth-, hand-, or power-operated whistle or horn, or some other means to make an efficient sound signal.
  • Vessels 65.6 feet or more in length are required to carry on board a whistle or horn, and a bell.
• No vessel may be equipped with a siren except vessels used by law enforcement officers.

Common Sound Signals

Some common sound signals that you should be familiar with as a recreational boater are as follows.

• A short blast lasts one second.
• A prolonged blast lasts 4-6 seconds.

Changing Direction

• One short blast tells other boaters "I intend to pass you on my port (left) side."
• Two short blasts tell other boaters "I intend to pass you on my starboard (right) side."
• Three short blasts tell other boaters "I am backing up."

Restricted Visibility

• One prolonged blast at intervals of not more than two minutes is the signal used by power-driven vessels when underway.
• One prolonged blast plus two short blasts at intervals of not more than two minutes is the signal used by sailing vessels.

Warning

• One prolonged blast is a warning signal (for example, used when coming around a blind bend or exiting a slip).
• Five (or more) short, rapid blasts signal danger or signal that you do not understand or that you disagree with the other boater's intentions.
