This unit involves the skills and knowledge required to maintain safe navigation of a vessel through the use of radar, automatic radar plotting aids (ARPAs) and other bridge equipment to determine vessel position.

This unit applies to people working in the maritime industry in the capacity of:

  • Master of a commercial vessel less than 80 metres in length within the exclusive economic zone (EEZ)
  • Master of a commercial vessel less than 500 gross tonnage (GT)
  • Master of a commercial vessel Unlimited
  • Watchkeeper Deck.

Licensing/Regulatory Information 

Legislative and regulatory requirements are applicable to this unit.

  • Regulatory requirements include STCW International Maritime Organization (IMO) model course competencies and areas of knowledge, understanding and proficiency, together with the estimated total hours required for lectures and practical exercises. Teaching staff should note that timings are suggestions only and should be adapted to suit individual groups of trainees depending on their experience, ability, equipment and staff available for training

Near Coastal Qualifications:

  • This unit is one of the requirements to obtain Australian Maritime Safety Authority (AMSA) certification as a Master less than 80 metres Near Coastal as defined in the Marine Order 505 (Certificates of competency - National Law) 2013.

Blue Waters Qualifications:

  • This unit is one of the requirements to obtain AMSA certification as a Master of a commercial vessel less than 500 gross tonnage (GT), Master Unlimited or Watchkeeper Deck and to meet regulatory requirements this unit must be delivered consistent with Marine Orders and with the relevant sections of the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW).

3.5 

Manoeuvring signals are made at appropriate time according to regulations

3.6 

Bridge equipment is used and maintained according to manufacturer requirements and organisational procedures

4 

Maintain navigational records 

4.1 

Navigational data produced by bridge equipment that should be retained to conform with organisational procedures and regulatory requirements is identified

4.2 

Navigational data is stored electronically or in hard copy as required by organisational procedures and regulatory requirements

4.3 

Security and access requirements for data are adhered to according to organisational procedures

Foundation Skills

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range of Conditions

Range is restricted to essential operating conditions and any other variables essential to the work environment.
