72 COLREGS

• An acronym for COLLISION REGULATIONS.
• TWO sets International and Inland
• Inland separated from International by
  DEMARCATION lines printed right on the navigation
  charts.
• WHERE THEY APPLY
• International rules apply To ALL vessels on the
  high seas and in all waters connected therewith
  NAVIGABLE BY SEAGOING VESSELS.
• The COLREGS were set by convention in 1972,
  subject to continual amendments.

3
COLREGS, Contd
Further, these rules shall NOT interfere with
special rules made by an appropriate authority. A
proper authority in the U.S. would be the
USCG. NOTE There is one other such set of
rules, called the INLAND Rules act of 1980.
4
DEFINITIONSSHALL and MAY
The naval services, including the U.S. Coast
Guard have agreed by convention and documentation
on the following interpretation(s) SHALL is a
COMMAND. There is no alternative. MAY is a
SUGGESTION and alternatives are available. These
interpretations and definitions are made a part
of the laws governing vessels on the seas of all
signing countries.
5
Rule 1 Application

• International These Rules shall apply to all
  vessels upon the high seas and in all waters
  connected therewith navigable by seagoing
  vessels.
• Inland These Rules apply to all vessels upon
  the inland waters of the United States, and to
  the vessels of the United States on the Canadian
  waters of the Great Lakes to the extent that
  there is no conflict with Canadian law.

Rule 2 - RESPONSIBILITY

• KNOWN AS THE RULE OF GOOD SEAMANSHIP AND THE
• GENERAL PRUDENTIAL RULE
• Nothing in these rules shall exonerate any
  vessel, owner, captain or crew from penalty for
  the neglect of complying with the rules, or by
  the ordinary practice of good seamanship or by
  the SPECIAL CIRCUMSTANCES of the case
• In following the rules, due regard SHALL be given
  to all dangers of navigation and collision and to
  any SPECIAL CIRCUMSTANCES,WHICH MAY MAKE A
  DEPARTURE FROM THESE RULES NECESSARY TO AVOID
  IMMEDIATE DANGER.

7
SPECIAL CIRCUMSTANCES
Special Circumstances are considered situations
NOT COVERED BY THE RULES. Since MEETING, CROSSING
and OVERTAKING rules are designed for ONLY TWO
vessels interacting, THREE VESSELS COMING
TOGETHER IS CONSIDERED A SPECIAL
CIRCUMSTANCE. When more than two vessels
interact, it becomes a SPECIAL CIRCUMSTANCE
8
PURPOSE OF THE RULES
The sole purpose of this set of rules is TO
PREVENT COLLISIONS! Period. COLLISIONS WITH
ANYTHING! If your actions in any situation
produce a collision between your vessel, and
ANYTHING, INCLUDING THE BOTTOM, you have broken
the rules and are subject to punishment! ADMIRALIT
Y LAW Some cases are tried in Admiralty Court
where the justice system, unlike our civil and
criminal courts which allow for a pleaDOES NOT
PROVIDE FOR A PLEA. In Admiralty Court, you are
presumed guilty as charged. The only reason you
are there is to find out what the punishment will
be. Mitigating circumstances are allowed to be
argued but you are still GUILTY AS CHARGED.

Rules 3, 4, 5

• Rule 3 Definition of Terms
• Rule 4 Rules in this subpart (Steering and
  Sailing Rules) apply in any condition of
  visibility.
• Rule 5 Look-Out, Every vessel shall at all
  times maintain a proper look-out by sight and
  hearing as well as by all available means
  appropriate in the prevailing circumstances and
  conditions so as to make a full appraisal of the
  situation and of the risk of collision.

10
DEFINITIONS

1. POWER DRIVEN VESSEL Propelled by MACHINERY.
2. UNDERWAY Not anchored, aground or made fast to
   shore.
3. SHORT BLAST 1 second symbol ?
4. PROLONGED BLAST 4 - 6 seconds symbol

1. SAILING VESSEL Propelled by SAIL ONLY
2. SAFE SPEED Depends on a number of ingredients
   visibility, traffic, your maneuverability, wind,
   sea, current, etc.

11
DEFINITIONS CONTd

1. VESSEL Includes every description of water craft
   used as a means of transportation on the water,
   including Hovercraft, Hydrofoils, Seaplanes and
   barges.
2. POWER DRIVEN VESSEL Any vessel propelled by
   machinery.
3. COMPOSITE UNIT Special built two-part hull, when
   joined by hydraulic rams, is considered a motor
   vessel rather than a towing vessel. Acts unto
   the waves as one.
4. SAILBOAT Any vessel under sail provided that
   propelling machinery, if fitted, is NOT being
   used.

12
LOOKOUT RULE
DEFINITION A person assigned to do NOTHING
except be an extra set of eyes for the captain.(
NO EXCEPTIONS) RULE Every vessel is required to
maintain a PROPER lookout at all times using
eyes/ears and any other means available. If a
collision occurs, the Lookout was IMPROPER! No
exceptions!
13
Rules 6 Safe Speed

• Rule 6, Safe Speed, Every Vessel shall at all
  times proceed at a safe speed so that she can
  take proper and effective action to avoid
  collision and be stopped within a distance
  appropriate to the prevailing circumstances and
  conditions. In determining a safe speed, the
  following factors shall be among those taken into
  account By all vessels the state of
  visibility, the traffic density, the
  maneuverability of the vessel with special
  reference to stopping distance and turning
  ability, at night, the presence of background
  lights (shore lights), the state of the wind,
  sea, and current, and the proximity of
  navigational hazards, and the draft in relation
  to the available depth of water. (b)
  additionally, by vessels with operational radar
  the characteristics, efficiency and limitations
  of the radar equipment any constraints imposed
  by the radar range scale usedand more.

14
Rule 7, RISK OF COLLISION
EVERY vessel SHALL use all available means,
including radar and lookout, to help in
determining if there is a risk of collision. IF
THERE IS ANY DOUBT, SUCH RISK SHALL BE DEEMED TO
EXIST. (If there was a collision, there must
have been a risk!) A risk exists if the bearing
of an approaching vessel does not appreciably
change. In cases of large vessels or vessels
close by even a large bearing change does NOT
guarantee that there is no risk of collision.
15
Rule 8 ACTION TO AVOID COLLISION
Action SHALL be positive and made in AMPLE TIME.
Any alteration of course or speed to avoid
collision SHALL be large enough to be understood
by another vessel observing visually or by radar.
Small course and speed changes should be avoided
for that reason. Any action to avoid a collision
MUST NOT result in another close quarters
situation.Close quarter situations should always
be avoided. Perhaps a course change alone will
do. This rule allows a stand-on vessel to
consider the hazards of holding course and speed.
However, if the SO departs, they are still liable
for breaking the rule of NOT holding course and
speed. You get to explain what happened! If
necessary to avoid collision or allow more time
to assess the situation, a vessel shall slacken
her speed or take all way off by stopping or
reversing her means of propulsion.
16
Rule 9, Narrow Channels

• A vessel proceeding along the course of a narrow
  channel or fairway shall keep as near to the
  outer limit of the channel or fairway which lies
  on her starboard side as is safe and practicable.
  
• Notwithstanding paragraph (a)(i) and Rule 14 (a),
  a power-driven vessel operating in narrow
  channels or fairways on the Great Lakes, Western
  Rivers, or waters specified by the Secretary, and
  proceeding downbound with a following current
  shall have right-of-way over an upbound vessel.
• A vessel shall not cross a narrow channel or
  fairway if such crossing impedes the passage of a
  vessel which can safely navigate only within that
  channel or fairway. The latter vessel shall use
  the danger signal prescribed in Rule 34d if in
  doubt as to the intention of the crossing vessel.
  Note (shall for inland, may for international).
  
• Must use sound signals when overtaking in narrow
  channels
• Must use the bend signal when rounding tight
  bends
• Every vessel shall, if the circumstances of the
  case admit, avoid anchoring in a narrow channel.

17
Rule 10 Traffic Separation Schemes

• (a) This Rule applies to traffic separation
  schemes and does not relieve any vessel of her
  obligation under any other Rule. (b) A vessel
  using a traffic separation scheme shall proceed
  in the appropriate traffic lane in the general
  direction of traffic flow for that lane (ii) so
  far as practicable keep clear of a traffic
  separation line or separation zone (iii)
  normally join or leave a traffic lane at the
  termination of the lane, but when joining or
  leaving from either side shall do so at as small
  an angle to the general direction of traffic flow
  as practicable.
• (c) A vessel shall, so far as practicable, avoid
  crossing traffic lanes but if obliged to do so
  shall cross on a heading as nearly as practicable
  at right angles to the general direction of
  traffic flow.

18
Rules 11-19

• Rule 11 (Application), Rules in this section
  apply to vessels in sight of one another.
• Rule 12, Sailing Vessels, Starboard tack over
  port, leeward over windward.
• Rule 13, Overtaking
• Rule 14, Head-On Situation
• Rule 15, Crossing Situation
• Rule 16, Action by Give-way Vessel
• Rule 17, Action by Stand-on Vessel

  Visibility

19
MEETING CROSSING - OVERTAKING
Underway, a vessel is ALWAYS in one of three
configurations MEETING, CROSSING or
OVERTAKING MEETING BOW TO BOW.At night Both
side lights of the other vessel are
visible. CROSSING Only one side of other vessel
is in view. Nighttime, only one sidelight is in
view. OVERTAKING Approaching from more than 2
points abaft the beam, either side. Night lights
of the running lights, only the stern light of
the other vessel will be visible.
20
OVERTAKINGAny vessel overtaking any other shall
keep out of the way of the vessel being
overtaken. (b) A vessel shall be deemed to be
overtaking when coming up with another vessel
from a direction more than 22.5 degrees abaft her
beam, that is, in such a position with reference
to the vessel she is overtaking, that at night
she would be able to see only the sternlight of
that vessel but neither of her sidelights. (c)
When a vessel is in any doubt as to whether she
is overtaking another, she shall assume that this
is the case and act accordingly.
GIVE WAY VESSEL
21
LIGHT DEFINITIONS Rule 21MASTHEAD LIGHT
A segmented white light, visible from dead ahead
to 2 points abaft the beam on each side or for
112.5 degrees on each side, from dead ahead, for
a total of 225 deg. It is always displayed
foreword and as high as practical, preferably on
a mast . The dark portion is ALWAYS FACING AFT.
22
MEETING
23
MEETINGPASSING PORT TO PORT
One short blast each
24
NORMAL PASSING
25
CROSSINGWhen two power-driven vessels are
crossing so as to involve risk of collision, the
vessel which has the other on her starboard side
shall keep out of the way and shall, if the
circumstances of the case admit, avoid crossing
ahead of the other vessel.
26
GIVE WAY VESSEL
NOTE THERE IS NO SUCH THING AS RIGHT OF
WAY ANYMORE. ONLY STAND-ON AND GIVE-WAY! Some
older texts continue to occasionally use the tem
right of way. The designated GIVE - WAY vessel
SHALL take early and substantial action to KEEP
CLEAR. She should NOT cross the bow of the Stand
ON vessel, nor create another close quarters
situation by turning towards the S.O. vessel.
27
GIVE WAY VESSELS DANGER ZONE
28
DANGER ZONE

1. EVERY VESSEL HAS A DANGER ZONE WHICH EXTENDS FROM
   DEAD AHEAD TO 2 POINTS ABAFT THE BEAM ON THE
   STARBOARD SIDE ONLY.
2. ANY VESSEL ENTERING YOUR DANGER ZONE, no matter
   how, AUTOMATICALLY BECOMES THE STANDON VESSEL..
   While such, he must hold his course and speed at
   all times.
3. At the same time, your vessel automatically
   becomes the GIVEWAY VESSEL and must stay out of
   the way of the STAND ON vessel at all times.
4. The STAND ON GIVE WAY situation results from
   VESSEL INTERACTION with other
   vessels only.

29
STAND - ON VESSEL
When one vessel must give way, the other vessel
MUST HOLD COURSE and SPEED( unless operating
under Rule 8) The S.O. Vessel may take action to
avoid collision as soon as it is apparent to her
that the give-way vessel is not taking proper
action to do so. When vessels are so close that
action by the give-way vessel alone will not
avoid a collision, the other vessel must act to
do so. Action by the stand-on vessel to avoid a
collision does not relieve the give-way vessel of
her obligation to keep out of the way.
30
DEFINITIONS CONTdSEVEN CLASSES OF VESSELS

• NUC Vessel Not Under Command. Due to some
  exceptional circumstance, cannot maneuver
  according to the rules. Unable
• to keep out of the way. Highest priority of
  AVOID.
• RAM Restricted in Ability to Maneuver due to
  nature of her work. Unable to keep out of way of
  other vessels. Next highest order of AVOID.
• CBD Constrained By Draft. Cannot maneuver out of
  the way because of insufficient water Needs their
  half of channel in the middle! This designation
  exists ONLY in Inland rules. NOT in International
  rules,

lines, trawling, or other apparatus restricting
her maneuvering ability. 5. SAILBOAT Sail only
no power on. 6. POWER BOAT Propelled by
machinery 7. SEAPLANES, HOVERCRAFT in the
displacement mode, Just remember New Reels

32
Rule 19 Restricted Visibility

• (a) This Rule applies to vessels not in sight of
  one another when navigating in or near an area of
  restricted visibility.
• (b) Every vessel shall proceed at a safe speed
  adapted to the prevailing circumstances and
  conditions of restricted visibility. A
  power-driven vessel shall have her engines ready
  for immediate maneuver.
• (e) Except where it has been determined that a
  risk of collision does not exist, every vessel
  which hears apparently forward of her beam the
  fog signal of another vessel, or which cannot
  avoid a close-quarters situation with another
  vessel forward of her beam, shall reduce her
  speed to the minimum at which she can be kept on
  her course. She shall if necessary take all her
  way off and in any event navigate with extreme
  caution until danger of collision is over.

33
Rule 20 Application for Part C (Lights and Shapes)

• (a) Rules in this Part shall be complied with in
  all weathers.
• (b) The Rules concerning lights shall be complied
  with from sunset to sunrise, and during such
  times no other lights shall be exhibited, except
  such lights as cannot be mistaken for the lights
  specified in these Rules or do not impair their
  visibility or distinctive character, or interfere
  with the keeping of a proper look-out.
• (c) The lights prescribed by these Rules shall,
  if carried, also be exhibited from sunrise to
  sunset in restricted visibility and may be
  exhibited in all other circumstances when it is
  deemed necessary.
• (d) The Rules concerning shapes shall be complied
  with by day.

34
LIGHT DEFINITIONS RULE 21SIDE LIGHTS
COLORED RED OR Green. RED is for PORT (Port
Wine) side GREEN is for starboard. Visible from
dead ahead to 112.5 degrees only each
light. Vessels of less than 20 meters may combine
the two into one lantern on the centerline such
as on the bow or breasthook of the boat. They are
displayed on the bow when combined or generally
near the forward quarter on each side.
35

short tow. Example 120M tow boat with a 250M tow
behind 4 MH vertically Two MH lights for power
vessels more than 50M in length, 1 MH light for
working as a tow boat and 1 for towing a tow in
excess of 200 meters. Four is the maximum number

43
TOWING/PUSHING LIGHTS
In addition to the Masthead and side lights,
power vessels towing on a hawser will show the
YELLOW TOWING LIGHT above the white stern light.
YELLOW OVER WHITE, MY HAWSERs TIGHT! or Yellow
over white, towing at night! When PUSHING ahead
or towing alongside, the white sternlight is out
and TWO YELLOW TOWING LIGHTS will be shown, one
over the other. YELLOW OVER YELLOW, IM A
PUSHING MY INLAND FELLOW! (INLAND RULE ONLY).
44
KINDS OF LIGHTS

• THERE ARE THREE KINDS OF NIGHT LIGHTS

  and running side lights, stern light and
  masthead light.
• Working lights Tells the world how big you are
  and how you are working Masthead lights, towing
  lights
• Identification lights Tells the world who you
  are NUC, RAM, FISH, SAIL, etc.

46
SOUND SIGNALS
Whenever it becomes necessary to signal another
vessel of your intended course changes or that
you are going to make them, they are communicated
by a WHISTLE, HORN OR LIGHT in a series of dots
and dashes. DOT one short blast by whistle or
light of one second duration DASH one PROLONGED
BLAST by whistle or light OF 4-6 SECOND
DURATION. NOTE there is no such thing as a
LONG BLAST! No matter where you hear it or who
says it!
47
SOUND and LIGHT SIGNALS
Vessels less than 12 meters do NOT REQUIRE either
a whistle or a bell, but this does NOT relieve
the vessel from having this equipment or some
other means of making an efficient sound
signal.
48
ACTION/WARNING SIGNALS

• One short blast You are going to
  turn your boat to your right
• ? ? Two short blastsYou are going to turn
  your boat to the left
• ? ? ? Three short blasts I AM
  OPERATING ASTERN PROPULSION
• ? ? ? ? ? Five or more short blasts The
  International DANGER or DOUBT signal.
• ??? Four Shorts Reserved for the PILOT BOAT
  ONLY! It says I am a PILOT BOAT Stay away!

?
49
HOW THEY ARE INTERPRETED
ONE SHORT BLAST (In sight of other vessel)
Inland Rules I INTEND TO LEAVE YOU ON MY PORT
SIDE. Requires CONSENT and REPLY. Same signal as
sent. International Rules ( OPEN WATER) I AM
ALTERING COURSE TO STARBOARD. No Reply or
consent required in open water. Clear the area
and GO! Note Draw a diagram of this maneuver.
Look at the maneuver relative to another boat and
the literal interpretation. Its just common
sense.
50
INTERPRETATION OF SOUND SIGNALS
SIGNAL TWO SHORT BLASTS INLAND WATERS I
INTEND TO LEAVE YOU ON MY STARBOARD SIDE. CONSENT
AND REPLY Same signal sent. INTERNATIONAL
WATERS I am altering course to Port. CONSENT AND
REPLY (None in open water) None Clear the area
and GO!
51
INTERPRETATION
THREE SHORTS I am operating ASTERN
PROPULSION. This is NOT an action signal and
requires no consent or reply. NOTICE Do not read
anything into this statement.This does NOT say he
is backing down or that he has specific motion of
any kind. Small boats react almost immediately to
power applications. Large vessels must overcome
inertia before they actually begin to move. It is
more apparent when a large vessel is in normal
cruise and then needs to stop. It may take
several to many hours of max power in astern
propulsion, for the large vessel to even begin to
slow down, much less stop.
52
ASTERN PROPULSION
53
ANCHORED SIGNALS IN FOG

1. Vessels less than 100 meters Rapid ringing of
   the Bell for 5 seconds.
2. Vessels 100 meters or more Rapid ringing of the
   Bell forward, then rapid sounding of the GONG
   from the aft. Each for 5 seconds.
3. Signals to be repeated in intervals of NOT LESS
   THAN one minute.
4. Can supplement regular sound signal with SHORT
   PROLONGED SHORT BLASTS Which say..ships
   position stationary!
5. For the PILOT BOAT four shorts AFTER THE BELL
   SIGNALS.

54
AGROUND SIGNALS IN FOG
SAME SIGNALS AS ANCHORED, EXCEPT ADD THREE STRONG
CLAPS ON THE BELL BEFORE AND AFTER THE RAPID
RINGING OF THE BELL. The three strong claps on
the bell DO NOT go with the GONGOnly on the
Bell! Sound the GONG the same as if you were
anchored. Repeat interval is also NOT LESS THAN
one minute. SPECIAL NOTE Care must be taken NOT
to sound a bell too frequently, so as to make it
sound like a continuous signal. ANY CONTINUOUS
SOUND SIGNAL IS CONSIDERED TO BE AN INTERNATIONAL
DISTRESS SIGNAL.
55
DAY SHAPES
Day shapes are BLACK in color and vary in size.
They are either Balls, Diamonds or Triangles
except for one Basket and one Cylinder. They are
flown when needed from the highest point or yard
where they can be readily seen. ANCHORED One
