What an assessment for MARH017 must cover

66 assessable components: 4 elements (17 performance criteria), 14 performance evidence and 35 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Set up wheelhouse navigation equipment

  • 1.1Wheelhouse navigation equipment is initialised and displays are set up and maintained
  • 1.2Operational performance and accuracy of wheelhouse equipment is confirmed and appropriate actions are taken when performance is out of limits
  • 1.3Misrepresentation of information is detected and corrected or allowed for

2 Use radar to navigate safely

  • 2.1Radar is operated according to manufacturer instructions to produce data on position and speed of vessel, other vessels and fixed objects
  • 2.2Radar plot is constructed on a radar plotting sheet or automatic plotting devices are initialised
  • 2.3Systematic radar observations of vessels in the vicinity are made where there is a risk of collision
  • 2.4Radar data is used to obtain a position fix for vessel using electronic bearing lines and variable range markers
  • 2.5Radar bearings are corrected for vessel heading and compass error as appropriate
  • 2.6Radar plotting data is analysed to anticipate potential collisions
  • 2.7Analysis is used to make informed command decisions on actions needed to avoid collisions

3 Use wheelhouse navigation equipment

  • 3.1Wheelhouse navigation equipment is safely and efficiently used to conduct navigation of the vessel
  • 3.2Position of vessel is monitored during voyage to ensure planned passage is followed
  • 3.3Movement of vessels in the vicinity is monitored to ensure collision situations do not occur
  • 3.4Wheelhouse navigation equipment is maintained according to manufacturer requirements and organisational procedures

4 Maintain navigational records

  • 4.1Navigational data produced by wheelhouse navigation equipment that should be retained to conform with organisational procedures and regulatory requirements is identified
  • 4.2Navigational data is stored electronically or in hard copy as required by organisational procedures and regulatory requirements
  • 4.3Security and access requirements for data are adhered to according to organisational procedures

Performance evidence

  • constructing a radar plot
  • interpreting radar displays
  • reading and interpreting service manuals and instructions for radar and other electronic navigational aids
  • recognising faulty radar equipment and taking appropriate actions
  • recognising problems when using radar and other navigational aids, to maintain safe navigation, and taking appropriate actions
  • incorrect radar settings for heading marker and range marker
  • incorrect set up of electronic chart system (ECS)
  • incorrect set up of global navigation satellite system (GNSS) receiver
  • rain clutter
  • sea clutter
  • setting up and operating an automatic radar plotting aid (ARPA)
  • setting up and operating marine radar equipment on a vessel
  • setting up and operating or using other navigational instruments and equipment on a vessel
  • using radar to determine actions to avoid a close-quarters situation or collision with another vessel in accordance with the International Regulations for the Prevention of Collision at Sea

Knowledge evidence

  • different types of navigational aids, including their features, key applications and operational characteristics
  • alarm devices, including off-course and watch alarms
  • automatic identification system (AIS)
  • automatic pilot
  • azimuth mirrors or pelorus
  • coverage areas
  • echo sounders
  • electronic charting systems (ECS)

  • procedures for the use of data generated by radar and other navigational instruments
  • process for identifying and storing navigation data
  • radar plotting, including
  • course and speed of other vessels
  • detecting course changes of other ships
  • effects of changes in own ships course and/or speed
  • target’s closest point of approach and time of closest point of approach
  • recognising problems when using radar and other navigational aids to maintain safe navigation, and taking appropriate actions, including
  • false echoes
  • global positioning system (GPS) or differential global positioning system (DGPS) errors
  • recognising radar display of search and rescue transponders (SART) and racon signals
  • recording courses steered
  • relevant sections of state and territory regulations and Marine Order 505 dealing with navigational equipment and the responsibilities of a Master or deck officer
  • techniques for the use of radar and other navigational instruments
  • terminology and principles of operation of radar and other navigation aids typically used on vessels
  • using radar to assist in collision avoidance in accordance with International Regulations for the Prevention of Collision at Sea
  • weather and oceanographic reports
  • work health and safety (WHS)/occupational health and safety (OHS) requirements and work practices

Questions about assessing MARH017

What does an assessment tool for MARH017 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MARH017 needs to address all 66 unit components: 4 elements with 17 performance criteria, 14 performance evidence requirements, 35 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for MARH017?

Auditori pulls the current release of MARH017 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MARH017 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MARH017 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MARH017, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
