Marine Navigation Equipment Inspection Checklist [FREE PDF]

Navigation equipment inspections are mandated under SOLAS Chapter V Regulation 19 and USCG 46 CFR Part 80, requiring vessels to maintain fully operational navigational aids at all times. Failure to comply may result in port state control detention, fines, or vessel unseaworthiness rulings. This checklist guides Marine Surveyors and Chief Officers through a comprehensive assessment of all primary and backup navigation systems.

  • Industry: Maritime
  • Frequency: Monthly
  • Estimated Time: 45-60 minutes
  • Role: Chief Officer
  • Total Items: 36
  • Compliance: SOLAS Chapter V Regulation 19 - Carriage Requirements for Shipborne Navigational Systems, USCG 46 CFR Part 80 - Navigation Equipment, IMO Resolution MSC.302(87) - AIS Performance Standards, ISM Code Section 10 - Maintenance of the Ship and Equipment, IMO Resolution A.694(17) - General Requirements for Shipborne Radio Equipment

Radar Systems

Verify operational status and performance of primary and secondary radar installations.

  • Is the primary radar system operational and displaying accurate returns?
  • Is the secondary (backup) radar system operational and tested?
  • Are radar scanner housings and antenna mounts free from visible damage or corrosion?
  • Is ARPA (Automatic Radar Plotting Aid) functioning correctly with accurate tracking?
  • Have radar performance tests been conducted and logged within the required interval?

GPS / GNSS Systems

Assess the accuracy, integrity, and redundancy of satellite-based positioning systems.

  • Is the primary GPS/GNSS receiver displaying a valid position fix with sufficient satellite acquisition?
  • Is a secondary independent GPS or GNSS backup unit installed and operational?
  • Is the GPS position being compared and cross-checked against chart plotter and radar overlay?
  • Are GPS antenna cables, connectors, and mounting positions secure and undamaged?
  • Is the GPS alarm for loss of fix or position jump enabled and audible?

AIS (Automatic Identification System)

Confirm AIS Class A transponder operation, data accuracy, and transmission integrity.

  • Is the AIS Class A transponder powered on and transmitting vessel data correctly?
  • Are all static data fields (MMSI, IMO number, vessel type, dimensions) correctly programmed?
  • Is the AIS receiving and displaying targets from nearby vessels correctly?
  • Is the AIS antenna properly installed and verified free from interference sources?
  • Has the AIS unit been serviced or tested by a qualified technician within the certification period?

Magnetic & Gyro Compass Systems

Inspect gyrocompass, magnetic compass, and rate-of-turn indicators for accuracy and regulatory compliance.

  • Is the gyrocompass operational, settled, and displaying accurate heading?
  • Is the standard magnetic compass properly mounted, illuminated, and free from deviation errors?
  • Has the magnetic compass deviation card been updated within the required period?
  • Is the rate-of-turn indicator operational and reading zero when the vessel is steady on course?
  • Are gyrocompass repeaters in steering positions and engine room displaying accurate and consistent headings?

ECDIS & Chart Systems

Verify Electronic Chart Display and Information System compliance, data currency, and backup arrangements.

  • Is the ECDIS system type-approved and operating with current, up-to-date ENCs?
  • Has the ECDIS operator received type-specific training as required?
  • Is a backup navigation system (paper charts or second ECDIS) available and current?
  • Are ECDIS alarms (anti-grounding, off-track, depth contour) enabled and tested?
  • Is the voyage plan loaded, reviewed, and approved by the Master in the ECDIS?

VHF & GMDSS Communications

Test VHF radio, DSC controller, and GMDSS equipment for navigational safety communications.

  • Is VHF Channel 16 being monitored continuously on the bridge?
  • Is the DSC (Digital Selective Calling) controller correctly programmed with the vessel's MMSI?
  • Are NAVTEX receiver and weather fax equipment operational and receiving current broadcasts?
  • Are all GMDSS batteries tested and showing adequate charge levels for the required 6-hour reserve?
  • Is the voyage data recorder (VDR) or simplified VDR operational and annual capsule test current?

Bridge Equipment & Documentation

Assess general bridge equipment condition, logbooks, and calibration records.

  • Are all navigational lights operational and tested within the required inspection interval?
  • Is the echo sounder (depth finder) operational and calibrated for the current water conditions?
  • Are bridge logbooks (deck log, compass error log, radar log) current and properly maintained?
  • Are all navigation equipment certificates and type approvals valid and accessible on board?
  • Has a bridge equipment familiarization record been completed for all officers standing navigational watch?
  • Are any deficiencies, malfunctions, or near-miss events related to navigation equipment documented and reported?
