Where it sitsAbandon opens Chapter I — Distress – emergency. Two general-purpose repeat instructions come first; then the whole range of intention around leaving a vessel: the master's own decision, a request lacking the means, and the orders and questions aimed at another vessel.
The ordering rule of the block: it runs from what I am doing (AC–AE), through what I intend or refuse (AF), to what you should do (AG–AH), closing with a vessel spoken of in the third person (AI). The subject moves from me, to you, to her.
GroupMeaning
AARepeat all after . . .
ABRepeat all before . . .
ACI am abandoning my vessel.
ADI am abandoning my vessel which has suffered a nuclear accident and is a possible source of radiation danger.
AEI must abandon my vessel.
AE 1I (or crew of vessel indicated) wish to abandon my (or their) vessel, but have not the means.
AE 2I shall abandon my vessel unless you will remain by me, ready to assist.
AFI do not intend to abandon my vessel.
AF 1Do you intend to abandon your vessel?
AGYou should abandon your vessel as quickly as possible.
AHYou should not abandon your vessel.
AIVessel (indicated by position and/or name or identity signal if necessary) will have to be abandoned.
Three pairs that differ by one word. AG = you should abandon against AH = you should not; AF is my statement and AF 1 the same sentence turned into a question; AE is compulsion ("I must"), AE 1 a wish with no means, AE 2 a condition placed on you.
Two nuclear groups are missing here on purpose. AJ and AK belong to this family of ideas, but the source prints them only later, as cross-references inside the Radiation danger table. AD is the one nuclear group the Abandon table itself carries. Do not complete AJ/AK from memory — the only wording available is the one printed there.
The Code organises Assistance into four movements, always in this order: requirednot required or declinedgiven or not givenproceeding to assistance. A group's place in that march is half its meaning.
The three ways of askingNC = I am in distress and require immediate assistance — distress itself · CB = I require immediate assistance — bare, no distress declared · CC = I am (or vessel indicated is) in distress in lat . . . long . . . (or bearing . . . from place indicated, distance . . .) and require immediate assistance — the one that carries the position.
GroupCB and its eight complements — "I require immediate assistance; . . ."
CB 1I have a dangerous list.
CB 2I have damaged steering gear.
CB 3I have a serious disturbance on board.
CB 4I am aground.
CB 5I am drifting.
CB 6I am on fire.
CB 7I have sprung a leak.
CB 8Propeller shaft is broken.
GroupAssistance required — the rest of the block
VI require assistance.
WI require medical assistance.
CDI require assistance in the nature of . . . (Complements Table II).
TYI request assistance from fishery protection (or fishery assistance) vessel . . .
CEI will attempt to obtain for you the assistance required.
BFAircraft is ditched in position indicated and requires immediate assistance.
CFSignals from vessel/aircraft requesting assistance are coming from bearing . . . from me (lat . . . long . . . if necessary).
CGStand by to assist me (or vessel indicated).
CG 1I will stand by to assist you (or vessel indicated).
CHVessel indicated is reported as requiring assistance in lat . . . long . . .
CH 1Lightvessel (or lighthouse) indicated requires assistance.
CH 2Spaceship is down in lat . . . long . . . and requires immediate assistance.
CIVessel aground in lat . . . long . . . requires assistance.
GroupThe CJ questions · assistance not required or declined
CJDo you require assistance?
CJ 1Do you require immediate assistance?
CJ 2Do you require any further assistance?
CJ 3What assistance do you require?
CJ 4Can you proceed without assistance?
CKAssistance is not (or is no longer) required by me (or vessel indicated).
CLI offered assistance but it was declined.
GroupGiven / not given · proceeding to assistance
CMOne or more vessels are assisting the vessel in distress.
CM 1Vessel/aircraft reported in distress is receiving assistance.
CNYou should give all possible assistance.
CN 1You should give immediate assistance to pick up survivors.
CN 2You should send survival craft to assist vessel indicated.
COAssistance cannot be given to you (or vessel/aircraft indicated).
CO 1I cannot give the assistance required.
CPI am (or vessel indicated is) proceeding to your assistance.
CP 1SAR aircraft is coming to your assistance.
CRI am proceeding to the assistance of vessel/aircraft in distress in lat . . . long . . .
CTI (or vessel indicated) expect to reach you at time indicated.
CUAssistance will come at time indicated.
CU 1I can assist you.
CVI am unable to give assistance.
CV 1Will you go to the assistance of vessel indicated (in lat . . . long . . .)?
CV 2May I assist you?
CV 3Can you assist me (or vessel indicated)?
CV 4Can you assist?
The CV block is where marks are lost. CV = I cannot · CU 1 = I can · CV 2 = may I assist you · CV 3 / CV 4 = can you assist me. Same verb, opposite direction, one numeral apart.
Two of these are procedure signals, not assistance signals. The footnote marks CQ (Call for unknown station(s) or general call to all stations) and CS (What is the name or identity signal of your vessel (or station)?) with an asterisk: "* Procedure signal." They sit inside the sequence only by alphabetical order.
And the page closes with borrowed groups (CW–CX) whose home is elsewhere, gathered because each turns on whether assistance is needed: TZ (Can you offer assistance? — Complements Table II), AE 2, IX 1, IY, IY 1, KA 1, KN 1 and PK (I cannot steer without assistance).
Four movements again, and the rule is who holds the information: the vessel in distress (NC, CC, EC), the vessel that saw or heard it (DZ, EA, FF, EK), the position of it (EL–FI), and the vessel trying to reach it (EN–GF).
GroupVessel/aircraft in distress
DZVessel (or aircraft) indicated appears to be in distress.
DZ 1Is vessel (or aircraft) indicated in distress?
DZ 2What is the name (or identity signal) of vessel in distress?
EAHave you sighted or heard of a vessel in distress? (Approximate position lat . . . long . . . or bearing . . . from place indicated, distance . . .).
EA 1Have you any news of vessel/aircraft reported missing or in distress in this area?
EBThere is a vessel (or aircraft) in distress in lat . . . long . . . (or bearing . . . distance . . . from me, or Complements Table III).
ECA vessel which has suffered a nuclear accident is in distress in lat . . . long . . .
GroupDistress signals — understood, cancelled, intercepted
EDYour distress signals are understood.
ED 1Your distress signals are understood; the nearest life-saving station is being informed.
EFSOS/MAYDAY has been cancelled.
EF 1Has the SOS/MAYDAY been cancelled?
FFI have intercepted SOS/MAYDAY from vessel (name or identity signal) (or aircraft) in position lat . . . long . . . at time indicated.
EGDid you hear SOS/MAYDAY given at time indicated?
EJI have received distress signal transmitted by coast station indicated.
EJ 1Have you received distress signal transmitted by coast station indicated?
EKI have sighted distress signal in lat . . . long . . .
EK 1An explosion was seen or heard (position or direction and time to be indicated).
EK 2Have you heard or seen distress signal from survival craft?
The EPIRB block runs as a square, and the numeral tells you the corner. EG 1–EG 4 are the 2182 kHz set; EG 5–EG 8 repeat the identical four sentences for . . . MHz — will you listen / I am listening / have you received / I have received, in that fixed order.
2182 kHz. . . MHzSentence (emergency position-indicating radio beacons)
EG 1EG 5Will you listen on . . . for signals of emergency position-indicating radio beacons?
EG 2EG 6I am listening on . . . for signals of emergency position-indicating radio beacons.
EG 3EG 7Have you received the signal of an emergency position-indicating radio beacon on . . . ?
EG 4EG 8I have received the signal of an emergency position-indicating radio beacon on . . .
GroupPosition of distress · contact or locate
ELRepeat the distress position.
EL 1What is the position of vessel in distress?
FGPosition given with SOS/MAYDAY from vessel (or aircraft) was lat . . . long . . . (or bearing . . . from place indicated, distance . . .).
FG 1What was the position given with SOS/MAYDAY from vessel (or aircraft)?
FHPosition given with SOS/MAYDAY is wrong. The correct position is lat . . . long . . .
FIPosition given with SOS/MAYDAY by vessel is wrong. I have her bearing by radio direction-finder and can exchange bearings with any other vessel.
EMAre there other vessels/aircraft in the vicinity of vessel/aircraft in distress?
ENYou should try to contact vessel/aircraft in distress.
EOI am unable to locate vessel/aircraft in distress because of poor visibility.
EPI have lost sight of you.
EQI expect to be at the position of vessel/aircraft in distress at time indicated.
EQ 1Indicate estimated time of your arrival at position of vessel/aircraft in distress.
BII am flying to likely position of vessel in distress.
GFI have found vessel/aircraft in distress in lat . . . long . . .
GLI have located (or found) wreckage from the vessel/aircraft in distress (position to be indicated if necessary by lat . . . and long . . . or by bearing . . . from specified place and distance . . .).
Found the vessel, or found only wreckage? GF = I have found the vessel/aircraft in distress · GL = I have located (or found) wreckage from it. EP ("I have lost sight of you") is not a distress group at heart — it serves again as an instruction inside Search.
A footnote on this block points outside the Code: "* Reference is made to signals prescribed by the International Convention for the Safety of Life at Sea, 1974, as replies from life-saving stations or maritime rescue units to distress signals made by a ship or person. See appendix 3."
The longest block in the cutIt moves in a fixed sequence, and the Code keeps every internal subheading.
Proceeding to assistance → position of the accident → marking it → information and instructions → the search itself → results of search → rescue → results of rescue
GroupProceeding to the accident
FEI am proceeding to the position of accident at full speed. Expect to arrive at time indicated.
FE 1Are you proceeding to the position of accident? If so, when do you expect to arrive?
FF 1I have intercepted SOS/MAYDAY . . . at time indicated; I have heard nothing since.
Marking the accident is one group with five means, numbered FJ 1 to FJ 5 in a fixed order; bare FJ says only that the position is marked, and FK asks whether it is.
GroupPosition of accident (or survival craft) is marked . . .
FJ. . . is marked. (no means stated)
FJ 1. . . by flame or smoke float.
FJ 2. . . by sea marker.

GroupThe search itself
FRI am (or vessel indicated is) in charge of co-ordinating search.
FR 1Carry out search pattern . . . starting at . . . hours. Initial course . . ., search speed . . . knots.
FR 2Carry out radar search, ships proceeding in loose line abreast at intervals between ships . . . miles. Initial course . . . search speed . . . knots.

FUThe search area of the aircraft is between lat . . . and . . . and long . . . and . . .
FVSearch by aircraft/helicopter will be discontinued because of unfavourable conditions.
FWYou should search in the vicinity of lat . . . long . . .
FXShall I search in the vicinity of lat . . . long . . . ?
FYI am in the search area.
FY 1Are you in the search area?
BPAircraft is coming to participate in search. Expected arrive over the area of accident at time indicated.
FZYou should continue search according to instructions and until further notice.
FZ 1I am continuing to search.
FZ 2Are you continuing to search?
FZ 3Do you want me to continue to search?
GAI cannot continue to search.
GBYou should stop search and return to base or continue your voyage.
FW / FX and the FZ trio are the classic traps. FW orders, FX asks permission; FZ 1 states, FZ 2 asks about you, FZ 3 asks about me. The verb never changes — only who speaks about whom.
Six of the search groups carry an asterisk. The footnote reads: "* These signals are intended for use in connection with the International Aeronautical and Maritime Search and Rescue Manual (IAMSAR Manual) Volume III – Mobile Facilities." They are exactly FR 2 to FR 7 — not FR and not FR 1.
Two "report" groups frame this half and mirror each other: GC = Report results of search · GX = Report results of rescue. Everything between them is the operation itself.
GroupResults of search
GC 1Results of search negative. I am continuing to search.
GC 2I have searched area of accident but have found no trace of derelict or survivors.
GC 3I have noted patches of oil at likely position of accident.
GDVessel/aircraft missing or being looked for has not been heard of since.
GD 1Have you anything to report on vessel/aircraft missing or being looked for?

GroupRescue — taking people off, and the line-throwing apparatus
GMI cannot save my vessel.
GM 1I cannot save my vessel; keep as close as possible.
GNYou should take off persons.
GN 1I wish some persons taken off. Skeleton crew will remain on board.
GN 2I will take off persons.
GN 3Can you take off persons?
GOI cannot take off persons.
GPYou should proceed to the rescue of vessel (or ditched aircraft) in lat . . . long . . .
GQI cannot proceed to the rescue owing to weather. You should do all you can.
GRVessel coming to your rescue (or to the rescue of vessel or aircraft indicated) is steering course . . . , speed . . . knots.
GR 1You should indicate course and speed of vessel coming to my rescue (or to the rescue of vessel or aircraft indicated).
GSI will attempt rescue with whip and breeches buoy.
GTI will endeavour to connect with line-throwing apparatus.
GT 1Look out for rocket-line.
GUIt is not safe to fire a rocket.
GVYou should endeavour to send me a line.
GV 1Have you a line-throwing apparatus?
GV 2Can you connect with line-throwing apparatus?
GV 3I have not a line-throwing apparatus.
GWMan overboard. Please take action to pick him up (position to be indicated if necessary).
OMan overboard.
GroupResults of rescue — who was picked up, and in what state
GX 1What have you (or rescue vessel/aircraft) picked up?
GYI (or rescue vessel/aircraft) have picked up wreckage.
GZAll persons saved.
GZ 1All persons lost.
HAI (or rescue vessel/aircraft) have rescued . . . (number) injured persons.
HBI (or rescue vessel/aircraft) have rescued . . . (number) survivors.
HCI (or rescue vessel/aircraft) have picked up . . . (number) bodies.
HDCan I transfer rescued persons to you?
GZ and GZ 1 are one numeral apart and opposite in fact: all persons saved against all persons lost. In the HA–HC run the verb changes with the object: one rescues injured persons and survivors, but one picks up bodies.
The asterisk on GT points to the same 1974 SOLAS reference, this time "in connection with the use of shore life-saving apparatus. See appendix 3." GU sits in this block and is repeated later among the Warnings.
Where Search and rescue tracks the operation, this block tracks the people. HF–HK locate them, HL says they are not located, HM grades their condition, HN–HQ act on them.
Group"I have located . . ." — the object is the whole difference
HFI have located survivors in water, lat . . . long . . . (or bearing . . . from place indicated, distance . . .).
HGI have located survivors in survival craft lat . . . long . . . (or bearing . . . from place indicated, distance . . .).
HJI have located survivors on drifting ice, lat . . . long . . .
HKI have located bodies in lat . . . long . . . (or bearing . . . from place indicated, distance . . .).
HLSurvivors not yet located.
HL 1I am still looking for survivors.
HL 2Have you located survivors? If so, in what position?
GroupCondition of survivors — a four-step scale plus the question
HMSurvivors are in bad condition. Medical assistance is urgently required.
HM 1Survivors are in bad condition.
HM 2Survivors are in good condition.
HM 3Condition of survivors not ascertained.
HM 4What is condition of survivors?
GroupPick up · transfer · obtain information
HNYou should proceed to lat . . . long . . . to pick up survivors.
HOPick up survivors from drifting ice, lat . . . long . . .
HO 1Pick up survivors from sinking vessel/aircraft.
HPSurvivors have not yet been picked up.
HP 1Have survivors been picked up?
HQTransfer survivors to my vessel (or vessel indicated).
HQ 1Have you any survivors on board?
HRYou should try to obtain from survivors all possible information
HTYou should indicate position of survivors by throwing pyrotechnic signals.
The same words, two families. HM is the only one of the HM run that also requests medical assistance — which is why the source prints it inside Assistance as well; HM 1 states the identical bad condition and asks for nothing. Note also the missing letters: the block jumps HG → HJ; there is no HH or HI here.
CN 1 (You should give immediate assistance to pick up survivors) is printed inside this block too, as a cross-reference from the Assistance chapter — its home wording is the one already learned there.
Opening Chapter II — Casualties – damages, the block is built out of three numbered fans: HW 1–7 names what was struck, HX 1–4 grades the damage, HY 1–6 asks after the other vessel.
Group"I have (or vessel indicated has) collided with . . ."
HVHave you been in collision?
HW. . . surface craft.
HW 1. . . lightvessel.
HW 2. . . submarine.
HW 3. . . unknown vessel.
HW 4. . . underwater object.
HW 5. . . navigation buoy.
HW 6. . . iceberg.
HW 7. . . floating ice.
I have received . . .Above the waterlineBelow the waterline
serious damageHX 1HX 2
minor damageHX 3HX 4
The question that opens the damage fan is HX — "Have you received any damage in collision?". Read the square by pairs: odd numbers (HX 1, HX 3) are above, even numbers (HX 2, HX 4) are below; 1–2 serious, 3–4 minor.
GroupThe other vessel, the mat, the report
HYThe vessel (name or identity signal) with which I have been in collision has sunk.
HY 1. . . has resumed her voyage.
HY 2I do not know what has happened to the vessel with which I collided.
HY 3Has the vessel with which you have been in collision resumed her voyage?
HY 4What is the name (or identity signal) of the vessel with which you collided?
HY 5What is the name (or identity signal) of vessel which collided with me? My name (or identity signal) is . . .
HY 6Where is the vessel with which you collided?
HZThere has been a collision between vessels indicated (names or identity signals).
KAI urgently require a collision mat.
KA 1I have placed the collision mat. I can proceed without assistance.
KA 2Can you place the collision mat?
HY 5 is the only group in the fan spoken from the other side of the collision — the vessel struck asks the name and gives its own in the same breath. HZ is the third-party report: neither vessel is "I".
The fire block is a story in five beats: I am on fire (IT) → where (IV) → gaining or under control (IW–IY) → is it out (IZ) → what I need to fight it (JA).
GroupDeclaring the fire · locating it
ITI am on fire.
IT 1 · JI am on fire and have dangerous cargo on board; keep well clear of me.
IT 2Vessel (name or identity signal) is on fire.
IT 3Are you on fire?
IUVessel (name or identity signal) on fire is located at lat . . . long . . .
IVWhere is the fire?
IV 1I am on fire in the engine-room.
IV 2I am on fire in the boiler-room.
IV 3I am on fire in hold or cargo.
IV 4I am on fire in passenger's or crew's quarters.
IV 5Oil is on fire.
GroupGaining, controlled, extinguished
IWFire is under control
IXFire is gaining.
IX 1I cannot get the fire under control without assistance.
IX 2Fire has not been extinguished.
IYI can get the fire under control without assistance.
IY 1Can you get the fire under control without assistance?
IZFire has been extinguished.
IZ 1I am flooding compartment to extinguish fire.
IZ 2Is fire extinguished?
The trio that decides the question. IX 1 = I cannot, without assistance · IY = I can, without assistance · IY 1 turns the same sentence on you. And IX 2 ("not been extinguished") is a different fact from IX ("gaining"): a fire can be neither out nor gaining.
GroupJA — "I require . . ." : the appliance first, then the material for it
JA. . . fire-fighting appliances.
JA 1. . . foam fire extinguishers.
JA 2. . . CO2 fire extinguishers.
JA 3. . . carbon tetrachloride fire extinguishers.
JA 4. . . material for foam fire extinguishers.
JA 5. . . material for CO2 fire extinguishers.
JA 6. . . material for carbon tetrachloride fire extinguishers.
JA 7. . . water pumps.
The JA fan is a clean 1-2-3 / 4-5-6 mirror: the extinguishers in the order foam – CO2 – carbon tetrachloride, then the material for the same three in the same order, with JA 7 (water pumps) outside the mirror.
GroupExplosion
JBThere is danger of explosion.
JCThere is no danger of explosion.
JC 1Is there any danger of explosion?
JDExplosion has occurred in boiler.
JD 1Explosion has occurred in tank.
JD 2Explosion has occurred in cargo.
JD 3Further explosions are possible.
JD 4There is danger of toxic effects.
JEHave you any casualties owing to explosion?
Two groups reach this block from elsewhere: CB 6 (I require immediate assistance; I am on fire) from Assistance, and EK 1 (An explosion was seen or heard) from Distress signals. The single letter J repeats IT 1 word for word — the Code's own practice, not a duplicate entry.
The largest family in the cutIt is learned as an operation, not as a list.
Tug required (KF–KI) → can we tow at all (KJ–KL) → who tows whom (KM–KO) → prepare and commence (KP–KR) → the line and the hawser (KS–LA) → make fast and veer (LB–LF) → cast off (LG) → speed in tow (LH–LJ)
GroupTug

KPYou should tow me to the nearest port or anchorage (or place indicated).
KP 1I will tow you to the nearest port or anchorage (or place indicated).
KP 2I must get shelter or anchorage as soon as possible.
From KQ onwards the block becomes a strict "prepare → ready → commence" drill, and the rhythm holds: the even KQ numbers order you to prepare, the odd ones announce that I am ready.

Across KW, KX and KZ the odd numeral answers the even order. "You should . . ." carries the plain or even number; "I am / I have . . ." carries the next number up — KW 1 (towing hawser/cable is ready), KW 4 (spare is ready), KW 6 (wire hawser is ready), KX 1 (I am ready to receive), KX 3 (I am coming closer), KZ 1, KZ 3, KZ 5, LA 4. Lose the rhythm and you invert the speaker.

Where the LG fan is completed: LG 1 and LG 2 are my preparation and my readiness, LG 4 and LG 6 report the starboard and port hawsers cast off, LG 7 orders "cast off hawser(s)" without a side. And at the end of the cast-off table the source prints an "Engine manoeuvres" cross-reference (the whole of QD–QM plus RL, RL 1, RM, RM 1) — all of it belongs to Chapter IV Manoeuvres and is learned there, not here.
Chapter III opens with the things that mark the water and the waters that are marked: a buoy or beacon is established (LK) or removed (LL); a light is extinguished (LN); a lightvessel is out of position (LO).

LN 1All lights are out along this coast (or the coast of . . .).
LOI am not in my correct position (to be used by a lightvessel).
LO 1Lightvessel (name follows) is out of position.
LO 2Lightvessel (name follows) has been removed from her station.
LO is the one group the Code reserves to a kind of vessel. "I am not in my correct position" is annotated to be used by a lightvessel, and is spoken in the first person, while LO 1 reports a lightvessel out of position and LO 2 says she has been removed from her station: adrift is not withdrawn.
GroupBar — only depth and safety
LPThere is not less than . . . (number) feet or metres of water over the bar.
LQThere will be . . . (number) feet or metres of water over the bar at time indicated.
LRBar is not dangerous.
LR 1What is the depth of water over the bar?
LR 2Can I cross the bar?
LSBar is dangerous.
GroupCanal · channel/fairway
LXThe canal is clear.
LX 1The canal will be clear at time indicated.
LX 2You can enter the canal at time indicated.
LX 3Is the canal clear?
LX 4When can I enter the canal?
LYThe canal is not clear
LZThe channel/fairway is navigable.
LZ 1I intend to pass through the channel/fairway.
LZ 3What is the state of the channel/fairway?
LZ 4What is the least depth of water in the channel/fairway?
MAThe least depth of water in the channel/fairway is . . . (number) feet or metres.
MBYou should keep in the centre of the channel/fairway.
MB 1You should keep on the starboard side of the channel/fairway.
MB 2You should keep on the port side of the channel/fairway.
MB 3You should leave the channel/fairway free.
MCThere is an uncharted obstruction in the channel/fairway. You should proceed with caution.
MC 1The channel/fairway is not navigable.
MC 2The (-) lane of the traffic separation scheme is not navigable. (The direction of the traffic flow is to be indicated).
LZ 2 asks "Is the channel/fairway navigable?" and closes the LZ question run. YG — "You appear not to be complying with the traffic separation scheme" — is printed inside this table as a cross-reference; in this cut it never has a table of its own.
Three layers, and the grammar changes with each: an object is dangerous (MJ–MP), my vessel is the danger (MQ–MX, radiation), an act is dangerous (MY . . .), and finally you are the one in danger (NF–NH).
GroupDerelict – wreck – shoal
MJDerelict dangerous to navigation reported in lat . . . long . . . (or Complements Table III).
MKI have seen derelict (in lat . . . long . . . at time indicated).
MK 1Have you seen derelict (or wreckage)?
MLDerelict is drifting near lat . . . long . . . (or bearing . . . from place indicated, distance . . .).
ML 1Hull of derelict is awash.
ML 2Hull of derelict is well out of the water.
MMThere is a wreck in lat . . . long . . .
MM 1Wreck is buoyed.
MM 2Wreck is awash.
MNWreck (in lat . . . long . . .) is not buoyed.
MOI have struck a shoal or submerged object (lat . . . long . . .).
MPI am in shallow water. Please direct me how to navigate.
Buoyed or not buoyed is the pair the examiner reaches for. MM 1 = wreck is buoyed · MN = wreck is not buoyed — a different letter, not a numeral. "Awash" appears twice: the derelict's hull (ML 1) and the wreck (MM 2).
GroupRadiation danger — the area, then my own vessel
MQThere is risk of contamination due to excessive release of radioactive material in this area (or in area around lat . . . long . . .). Keep radio watch. Relay the message to vessels in your vicinity.
MQ 1The radioactive material is airborne.
MQ 2The radioactive material is waterborne.
MRThere is no, or no more, risk of contamination . . . in this area.
MR 1Is there risk of contamination . . . in this area?
MSMy vessel is a dangerous source of radiation.
MS 1. . . you may approach from my starboard side.
MS 2. . . you may approach from my port side.
MS 3. . . you may approach from forward.
MS 4. . . you may approach from aft.
MTMy vessel is a dangerous source of radiation. You may approach from . . . (Complements Table III).
MUMy vessel is a dangerous source of radiation. Do not approach within . . . (number) cables.
MVMy vessel is releasing radioactive material and presents a hazard.
MWMy vessel is releasing radioactive material and presents a hazard. Do not approach within . . . (number) cables.
MXThe radioactive material is airborne. Do not approach from leeward.
The radiation table is where the nuclear cross-references live. AD (abandoning after a nuclear accident) and EC (a vessel that has suffered a nuclear accident is in distress) are repeated here, and AJ ("I have had a serious nuclear accident and you should approach with caution") and AK ("I have had a nuclear accident on board") exist in this cut only as these two lines. MS is a source of radiation; MV is actively releasing material — do not merge them.

NA 2Navigation is possible only with pilot assistance.
NA 3Navigation is prohibited within 500 m of this platform.
NA 5You have been detected navigating within a 500 m safety zone (about the platform bearing (-) from me) and will be reported.
NA 6Anchors with buoys extend up to one mile from this vessel/rig – you should keep clear.
NBThere is fishing gear in the direction you are heading (or in direction indicated – Complements Table III).
NDTsunami (phenomenal wave) is expected. You should take appropriate precautions
VLTropical storm (cyclone, hurricane, typhoon) is approaching. You should take appropriate precautions.
NF · UYou are running into danger.

NGYou are in a dangerous position.
NG 1You are in a dangerous position; there is a radiation hazard.
NHYou are clear of all danger.
NH 1Are you clear of all danger?
NII have (or vessel indicated has) a list of . . . (number) degrees to starboard.
NJI have (or vessel indicated has) a list of . . . (number) degrees to port.
The NE run says the same seven words and changes only the reason: "You should proceed with great caution" — bare (NE), the coast is dangerous (1), submarines are exercising (2), there is a boom across (3), keep clear of firing range (4), hostile vessel (5), hostile submarine (6), hostile aircraft (7): the hostile trio always closes the fan in that order.
This table also gathers groups whose home is elsewhere: GU (It is not safe to fire a rocket), MC, RE (You should change your anchorage/berth. It is not safe.), UL (All vessels should proceed to sea as soon as possible owing to danger in port), TH, TI and TJ (navigate with caution — small fishing boats within . . . miles of me, drifting towards my set of nets, nets with a buoy in this area), and YG twice more. NA 4 mirrors NA 3 for "the platform bearing (-) from me".
Chapter IV is the most regular part of the Code, and one rule carries most of it: the Q letters run in twin blocks — ahead (QD–QH), then astern (QI–QM) — with the same sentences in the same order in each.
Ahead – headwayAstern – sternwaySentence
QDQII am going ahead / astern.
QD 1QI 1 · SMy engines are going ahead / astern.
QD 2QI 2I will keep going ahead / astern.
QD 3QI 3I will go ahead / astern.
QD 4QI 4I will go ahead / astern dead slow.
QEQJI have headway / sternway.
QFQKI cannot go ahead / astern.
QGQLYou should go ahead / astern.
QG 1QL 1You should go slow ahead / astern.
QG 2QL 2You should go full speed ahead / astern.
QG 3QL 3You should keep going ahead / astern.
QG 4QL 4You should keep your engines going ahead / astern.
QHQMYou should not go ahead / astern any more.
Learn the ahead column and the astern column comes free — if the offset is right: QD↔QI, QE↔QJ, QF↔QK, QG↔QL, QH↔QMa constant jump of five letters. Slip one letter and "you should go astern" becomes "I cannot go astern".
GroupAlongside
QNYou should come alongside my starboard side.
QN 1You should come alongside my port side.
QN 2You should drop an anchor before coming alongside.
QOYou should not come alongside.
QPI will come alongside.
QP 1I will try to come alongside.

QRI cannot come alongside.
QR 1Can I come alongside?
GroupTo anchor · anchor(s) · anchorage
QSYou should anchor at time indicated.
QS 2You should anchor to await tug.
QS 3You should anchor with both anchors.
QS 4You should anchor as convenient.
QTYou should not anchor. You are going to foul my anchor.
QUAnchoring is prohibited.
QVI am anchoring in position indicated.
QWI shall not anchor.
QW 1I cannot anchor.
QXI request permission to anchor.
QX 1You have permission to anchor.
QYI wish to anchor at once.
QY 1Where shall I anchor?

RB 2Where you have anchored (or intend to anchor) you are likely to drag.
RCI am (or vessel indicated is) breaking adrift.
RC 1I have broken adrift.
RDYou should weigh (cut or slip) anchor immediately.
RD 2I am unable to weigh my anchor.
REYou should change your anchorage/berth. It is not safe.
RFWill you lead me into a safe anchorage?
RGYou should send a boat to where I am to anchor or moor.
RHThere is no good holding ground in my area (or around lat . . . long . . .).
RIThere is good holding ground in my area (or around lat . . . long . . .).
Three near-identical refusals to anchor. QW = I shall not (my decision) · QW 1 = I cannot (impossibility) · QU = anchoring is prohibited (the rule). And in the holding-ground pair the negative comes first: RH is the bad ground, RI the good one, RI 1 the question.
QS 1 ("You should anchor", position if necessary) and QS 5 ("Are you going to anchor?") close the QS fan; QV 1 reports both anchors down; RD 1 sets the time for weighing; RG 1 asks at what time to come into anchorage. UB (heave to or anchor until pilot arrives), KP / KP 1 / KP 2, RW and RZ 1 are printed inside the Anchorage table as cross-references from Towing, Pilot and Proceed.
GroupEngines · propeller
RJYou should keep your engines ready.
RJ 2You should report when your engines are ready.
RJ 3You should leave when your engines are ready.
RK 1My engines are ready.
RLYou should stop your engines immediately.

RM 2I am obliged to stop my engines.
RNMy engines are out of action.
ROPropeller shaft is broken.
RO 1My propeller is fouled by hawser or rope.
RO 2I have lost my propeller.
The two stopping pairs sit one letter apart and mean opposite things. RL / RL 1 order you to stop your engines · RM / RM 1 report that mine are stopped or stopping. RM 2 adds compulsion; RN is breakdown, not a manoeuvre.
GroupLanding · boarding · manoeuvre
RPLanding here is highly dangerous.
RP 1Landing here is highly dangerous. A more favourable location for landing is at position indicated.
RQInterrogative or "the significance of the previous group should be read as a question".
RRThis is the best place to land.
RR 1Lights will be shown or flag waved at the best landing place.
DCBoat should endeavour to land where flag is waved or light is shown.
DD 1Boats are not allowed to land (after time indicated).

RT · XStop carrying out your intentions and watch for my signals.
RT 1What manoeuvres do you intend to carry out?
RU · DKeep clear of me; I am manoeuvring with difficulty.
RU 1I am carrying out manoeuvring trials.
The asterisks in the Landing block point outside the Code. RP, RP 1, RR and RR 1 carry: "* Reference is made to landing signals prescribed by the International Convention for the Safety of Life at Sea, 1974, for the guidance of small boats with crews or persons in distress. See appendix 3." RQ carries a double asterisk: "** Procedure signal." — it is no landing signal at all, only an alphabetical neighbour. SQ 3 is printed in the Boarding table as well as under Stop – heave to.

GroupV · Cargo – ballast
STWhat is your cargo?
SUSU 8My cargo is: agricultural products (SU) · coal (1) · dairy products (2) · fruit products (3) · heavy equipment/machinery (4) · livestock (5) · lumber (6) · oil/petroleum products (7) · I have a general cargo (8).

SW · BI am taking in, or discharging, or carrying dangerous goods.
SXYou should not discharge oil or oily mixture.
SYThe discharge of oil or oily mixture in this area is prohibited within . . . (number) miles from the nearest land.
The SU fan is alphabetical by cargo — agricultural, coal, dairy, fruit, heavy equipment, livestock, lumber, oil — and only SU 8 breaks the pattern, saying "I have a general cargo" instead of "My cargo is . . .".
