Sound signals must be used when needed and in restricted visibility.

There are only three types of sound-signal equipment mentioned in the Rules – whistle, bell and gong, with the latter only required on vessels 100 meters or more in length. As with everything else, the specifications of the equipment are prescribed in the rules. The whistle and gong are used by larger vessels when anchored in poor visibility in addition to the normal sound signals.

· A “short blast” is a signal on the foghorn (or whistle) of about one second duration.

· A “long blast” is of four to six second duration.

When moving, a ship may use the following basic signals to “contact” other ships:

· One short blast – I am altering my course to starboard.

· Two short blasts – I am altering my course to port.

· Three short blasts – I am operating astern propulsion.

VI. Different types of lights must be used aboard the ship. Read and translate Rule 21 of the International Regulations for Preventing Collisions at Sea 1972. Match types of lights with their definitions before:

1. “Masthead light”   2. “Sidelights”     3. “Stern light”     4. “Towing light”     5. “All-round light”   6. “Flashing light” a) means a light showing an unbroken light over an arc of the horizon of 360 degrees. b) means a yellow light placed as nearly as practicable at the stern showing an unbroken light over an arc of the horizon of 135 degrees and so fixed as to show the light 67.5 degrees from right aft on each side of the vessel. c) means a white light placed over the fore and aft centerline of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on either side of the vessel. d) means a light flashing at regular intervals at a frequency of 120 flashes or more per minute. e) means a white light placed as nearly as practicable at the stern showing an unbroken light over an arc of the horizon of 135 degrees and so fixed as to show the light 67.5 degrees from right aft on each side of the vessel. f) means a green light on the starboard side and a red light on the port side each showing light over an arc of the horizon of 112.5 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on its respective side.

VII. Find in the exercise above the English equivalents for the following words and expressions:

VIII. Self-assessment questions:

1. What is the minimum range of a masthead light on vessels of different lengths to be visible?

2. What colour should the masthead light be?

3. What colours should the sidelights be?

4. Should we use light and shape signals all the time?

5. When must shape signals be shown?

6. When must light signals be shown?
