4.6 - Look-out

4.6.1 - A proper look-out shall be maintained in compliance with rule 5 of the International Regulations for

Preventing Collisions at Sea, 1972. It shall serve the purpose of:

.l - Maintaining a continuous state of vigilance by sight and hearing as well as by all other available means,

with regard to any significant changes in the operating environment;

.2 - Fully appraising the situation and the risk of collision, stranding and other dangers to navigation; and

.3 - Detecting ships or aircraft in distress, shipwrecked persons, wrecks and debris.

4.6.2 - In determining that the composition of the navigational watch is adequate to ensure that a proper look-

out can continuously be maintained, the skipper shall take into account all relevant factors, including those

described under paragraph 4.1 of this regulation, as well as the following factors:

.1 - Visibility, state of weather and sea;

.2 - Traffic density, and other activities occurring in the area in which the vessel is navigating;

.3 - The attention necessary when navigating in or near traffic separation schemes and other routeing

measures;

.4 - The additional workload caused by the nature of the vessel’s functions, immediate operating requirements

and anticipated manoeuvres;

.5 - Rudder and propeller control and vessel manoeuvring characteristics;

.6 - The fitness for duty of any crew members on call who may be assigned as members of the watch;

.7 - Knowledge of and confidence in the professional competence of the vessel’s officers and crew;

.8 - The experience of the officer of the navigational watch and the familiarity of that officer with the vessel’s

equipment, procedures, and manoeuvring capability;

.9 - Activities taking place on board the vessel at any particular time, and the availability of assistance to be

summoned immediately to the wheelhouse when necessary;

.10 - The operational status of instrumentation in the wheelhouse and controls, including alarm systems;

.11 - The size of the vessel and the field of vision available from the conning position;

.12 - The configuration of the wheelhouse, to the extent such configuration might inhibit a member of the

watch from detecting by sight or hearing any external developments; and

.13 - Any relevant standards, procedures and guidelines relating to watchkeeping arrangements and fitness

for duty which have been adopted by the Organization.

4.7 - Protection of the marine environment

The skipper and the officer in charge of the watch shall be aware of the serious effects of operational or

accidental pollution of the marine environment, and shall take all possible precautions to prevent such pollution,

particularly within the framework of relevant international and port regulations.

4.8 - Weather conditions

The officer in charge of the watch shall take relevant measures and notify the skipper when adverse changes

in weather could affect the safety of the vessel, including conditions leading to ice accretion.

5 – Navigation with pilot embarked

The presence of a pilot on board does not relieve the skipper or officer in charge of the watch from their duties

and obligations for the safety of the vessel. The skipper and the pilot shall exchange information regarding

navigation procedures, local conditions and the vessel’s characteristics. The skipper and the officer in charge of

the watch shall co-operate closely with the pilot and maintain an accurate check of the vessel’s position and

movement.

stopping distance and the diameter of turning circle at sailing speed and with the fishing gear overboard;
