This document provides information about maritime signs, SOLAS conventions, and international distress signals. It discusses the purpose of maritime signs on vessels to identify hazards and equipment. It then outlines several visual distress signals agreed upon internationally, including signals to request assistance, medical assistance, or to answer yes/no questions from rescuers. Finally, it mentions the use of panels or cloth to make visual signals from liferafts and provides sources for further information.

2. This maritime sign is used by mariners to provide adequate
signage on board vessels. Furthermore, some flag states and
regulatory organizations require maritime signs on board to be
in compliance with the maritime governing regulations.
Maritime signs are critical in keeping a vessel's crew safe of
any possible hazards, all safety equipment easy to mark, and
provide directions on board a vessel.
SOLAS Life Saving Signals and Rescue
Methods

3. OBJECTIVE OF SOLAS
•The main objective of the SOLAS convention is
to specify minimum standars for the
construction, equipment and operation of ships,
compatible with their safety.

6. The signals illustrated in this leaflet are those to be used by any ship
or person in distress when communicating with search and rescue
units. They have been agreed internationally for this purpose and it
is important that you are familiar with them to ensure they are
correctly used in distress situations.

7. • Require Assistance: V
A V-shaped signal communicates that you need assistance, in general, but it doesn’t imply that you or
someone in your party is injured.
• Require Medical Assistance: X
Use the letter X to communicate that you or someone in your party needs medical attention. Whereas the V
symbol communicates a call for help, the X symbol communicates a more urgent request for assistance.
• No or Negative: N
The N symbol can be used to communicate your negative response to a question that the aircraft or rescue
organization has asked.
Yes or Affirmative: Y
The Y symbol can be used to communicate your affirmative response to a question that the aircraft or rescue
organization has asked.
• Proceed in this Direction: Arrow, pointing towards the location
Place an arrow-shaped symbol with the head, or point, of the arrow indicating the direction of your location.
This symbol is a good one to use when rescuers may need additional information about how to reach your
location after they have identified another ground-to-air signal, such as a group of X symbols in an open area
indicating a need for medical assistance.

8. PANEL SIGNAS
Survivors use liferaft sails to convey signals but any square
piece of clothe or canvas with each side of contransing color
can be used.

10. RECEPTION OF SAFETY MESSAGES
Any message which you hear prefixed by one of the
following words concerns SAFETY: If you hear these
words, pay particular attention to the message and call
the master or the officer on watch.

11. Air to ground visual signals

12. Surface to Air visual body signals.
