Regulation 28 - Records of navigational activities and daily reporting


  • Key navigational activities to be logged.
  • A complete record of the voyage must be able to be restored.
  • Daily reports to be sent to the company.
Regulation 28

1. All ships engaged on international voyages shall keep on board a record of navigational activities and incidents which are of importance to safety of navigation and which must contain sufficient detail to restore a complete record of the voyage, taking into account the recommendations adopted by the Organization*. When such information is not maintained in the ship's log-book, it shall be maintained in another form approved by the Administration.

2 Each ship of 500 gross tonnage and above, engaged on international voyages exceeding 48 hours, shall submit a daily report to its company, as defined in regulation IX/1, which shall retain it and all subsequent daily reports for the duration of the voyage. Daily reports may be transmitted by any means, provided that they are transmitted to the company as soon as practicable after determination of the position named in the report. Automated reporting systems may be used, provided that they include a recording function of their transmission and that those functions and interfaces with position-fixing equipment are subjected to regular verification by the ship's master. The report shall contain the following:

.1 ship's position;

.2 ship's course and speed; and

.3 details of any external or internal conditions that are affecting the ship's voyage or the normal safe operation of the ship.

* Refer to A.916(22) IMO Guidelines for the recording of events relating to navigation - Contained in Annex 22 - Recording of Navigational Events

MCA Guidance
1. Reg. 28.1 applies to all ships on international voyages except for UK-flagged pleasure vessels of less than 150 gt.

Reg. 28.2, requiring daily reporting for ships of 500 GT and above on international voyages exceeding 48 hours, came into force on 1 July 2006
[IMO Resolution MSC.142(77)]

3. The IMO Guidelines for Recording Navigational Events are contained in ANNEX 22. All bridge orders requiring changes in direction or speed of the main propulsion unit must be recorded. In addition other key navigational events should be recorded including changes of course, passing of way points, weather and sea conditions, incidents and events including pilot embarkation / disembarkation, tugs, hazardous occurrences and accidents.
4. Time-marked electronic or mechanical records are acceptable including those from echo sounders, course recorders, engine telegraphs and NAVTEX receivers.
5. It must be possible to reconstruct the ship's track throughout the voyage. The IMO Guidelines state that navigational records (whether paper, electronic or mechanical) should be retained on board for a period not less than 12 months. The MCA's interpretation of this requirement is that records retained for 12 months should provide sufficient detail to reconstruct any voyage during that period. The MCA recognises that it is impractical to retain voyage details on paper charts for longer than the duration of the voyage. Therefore sufficient details of waypoints, courses, times of alteration of course and or speed and other relevant details must be entered in the log book and courses and positions on all navigational charts should be retained until the voyage is completed. This information should be saved electronically when ECDIS is used to fulfil the requirements of Regulation 19 (para. 2.1.4)

The requirement for daily reports to be sent to the Company by ships of 500 GT and over on international voyages exceeding 48 hours can be met by any method of reporting. Automated reporting of position, course and speed must include a record of their transmission. The Master must regularly verify such transmissions against the position fixing equipment with which they are interfaced.

The "external or internal conditions" which must be reported as required by para 2.3 will include abnormal weather or sea conditions and any structural or mechanical defects affecting the voyage or safe operation of the ship.

7. Further guidance is contained in the notes following the IMO Guidelines in Annex 22.
