Corrections
When a mistake is made in a message, say: "Mistake ..." - followed by the word: "Correction ... " plus the corrected part of the message.

9.1 If any part of the message are considered sufficiently important to need safeguarding, say: "Repeat ... " - followed by the corresponding part of the message.
Example: "My draft is 12.6 repeat one-two decimal 6 metres." "Do not overtake - repeat - do not overtake."
9.2 When a message is not properly heard, say: "Say again (please)."
Numbers
Numbers are to be spoken in separate digits: "One-five-zero" for 150 "Two decimal five" or "Two point five" for 2.5
Note: Attention! When rudder angles e.g. in wheel orders are given, say: "Fifteen" for 15 or "Twenty" for 20 etc..
Positions
11.1 When latitude and longitude are used, these shall be expressed in degrees and minutes (and decimals of a minute if necessary), North or South of the Equator and East or West of Greenwich.
Example: "WARNING. Dangerous wreck in position 15 degrees 34 minutes North 061 degrees 29 minutes West."
11.2 When the position is related to a mark, the mark shall be a well-defined charted object. The bearing shall be in the 360 degrees notation from true north and shall be that of the position FROM the mark.
Example: "Your position bearing 137 degrees from Big Head lighthouse distance 2.4 nautical miles."
Bearings
The bearing of the mark or vessel concerned, is the bearing in the 360 degree notation from north (true north unless otherwise stated), except in the case of relative bearings. Bearings may be either FROM the mark or FROM the vessel.
Example: "Pilot boat is bearing 215 degrees from you."
Note: Vessels reporting their position should always quote their bearing FROM the mark, as described in paragraph 11.2 of this section.
12.1 Relative bearings Relative bearings can be expressed in degrees relative to the vessel's head. More frequently this is in relation to the port or starboard bow.
Example: "Buoy 030 degrees on your port bow." (Relative D/F bearings are more commonly expressed in the 360 degree notation.)
Courses
Always to be expressed in 360 degree notation from north (true north unless otherwise stated). Whether this is to TO or FROM a mark can be stated.
Distances
Preferably to be expressed in nautical miles or cables (tenths of a mile) otherwise in kilometres or metres, the unit always to be stated.
Speed
To be expressed in knots:
without further notation meaning speed through the water; or, "ground speed" meaning speed over the ground.
Times
Times should be expressed in the 24 hour UTC notation; if local time will be used in ports or harbours it should clearly be stated.
Geographical names
Place names used should be those on the chart or in Sailing Directions in use. Should these not be understood, latitude and longitude should be given.
Ambiguous words
Some words in English have meanings depending on the context in which they appear. Misunderstandings frequently occur, especially in VTS communications, and have produced accidents. Such words are:
1. The Conditionals "May", "Might", "Should" and "Could".
May: Do not say: "May I enter the fairway?"
Say: "QUESTION. Do I have permission to enter the fairway?"
Do not say: "You may enter the fairway."
Say: "ANSWER. You have permission to enter the fairway."
Might Do not say: "I might enter the fairway."
Say: "INTENTION. I will enter the fairway."
Should: Do not say: "You should anchor in anchorage B 3."
Say: "ADVICE. Anchor in anchorage B 3."
Could: Do not say: "You could be running into danger."
Say: "WARNING. You are running into danger."
The word "Can" either describes the possibility or the capability of doing something. In the SMCP the situations where phrases using the word "Can" appear make it clear whether a possibility is referred to. In an ambiguous context, however, say, for example:
"QUESTION. Do I have permission to use the shallow draft fairway at this time?", do not say: "Can I use the shallow draft fairway at this time?", if you ask for a permission. (The same applies to the word "May")
Note: In all cases the radiotelephone procedures as set out in the ITU - Radio Regulations have to be observed.
