25 SECTION 10.—MORSE SYMBOLS—PHONETIC TABLES—PROCEDURE SIGNALS Notes: 1. The signal “K”– • – by sound or light may be used by an icebreaker to remind ships of their obligation to listen continuously on their radio. 2. If more than one vessel is assisted, the distances between vessels should be as constant as possible. Watch speed of your own vessel and vessel ahead; should speed of your own vessel go down, give attention signal to the following vessel. 3. The use of these does not relieve any vessel from complying with the International Regulations for Preventing Collisions at Sea. 4. • • – • • Stop your headway (given only to a ship in an ice-channel ahead of and approaching or going away from icebreaker). I am stopping headway. Note: This signal should not be made by radiotelephone. Single-letter signals which may be used during icebreaking operations: * E • I am altering my course to starboard. * I • • I am altering my course to port. * S • • • I am operating astern propulsion. M – – My vessel is stopped and making no way through the water. Notes: 1. Signals of letters marked by an asterisk*, when made by sound, may only be made in compliance with the requirements of the International Regulations for Preventing Collisions at Sea. 2. Additional signals for icebreaking support can be found in Chapter 2, Section 6, Page 93 and 94
