Note this is a NAUTICAL LOG article only. To prepare an actual Voyage or Passage Plan the navigator MUST refer to "GUIDELINES FOR VOYAGE PLANNING" IMO RESOLUTION A.893 (21) Annex 25 of SOLAS V.

At the beginning of June 2009 Jeppesen Navigation (see our LINK LIST below) announced it had reached an agreement with the Chilean Naval Hydrographic Office to publish Jeppesen Marine Pilotage Charts covering Chilean waters. In our consulting capacity NAUTICAL LOG had cause to review voyage and passage planning generally. This in turn led to a complete review of IMO Resolution A.893 (21) Annex 25 of SOLAS V - Guidelines for Voyage Planning.

Recently there was a disgraceful, scathing, biased NTSB Report on the MS. "Cosco Busan" incident in which that vessel, under Compulsory Pilotage, rammed a bridge support in San Francisco Harbor. The NTSB Report was saved only by the dissent attachment by Member Deborah A. P. Hersman. One of the issues discussed was the responsibility of the vessel to plan the entire voyage from berth to berth. It occurred to NAUTICAL LOG that the IMO requirement might be improved upon and so here is the first Post of a series followed by a Proposal. We shall address the subject in two parts, "Guidelines for Voyage Planning" and "Ship Passage Planning".

Some background, IMO Resolution A. 285 (VIII) states:

"Despite the duties and obligations of a pilot, his presence on board does not relieve the officer of the watch from his duties and obligations for the safety of the vessel. He should co-operate closely with the pilot and maintain an accurate check on the vessel's position and movements. If he is in any doubt as to the pilot's actions or intentions, he should seek clarification from the pilot and if doubt still exists he should notify the master immediately and take whatever action is necessary before the master arrives."

Now from the above wording this seems to presume two things, first the Master is not on the Bridge, and second only males are officer of the watch. One must therefore further presume that the IMO is using "he" as a generic term. Also in a Compulsory Pilotage situation this places the OOW in a very tricky and difficult position. My advice would be for the OOW to immediately call the Master to the Bridge as soon as he/she feels any unease with the Pilot.

Guidelines for Voyage Planning


The development of a plan for the voyage or passage as well as the close and continuous monitoring of the vessel's progress and position during the execution of the plan. The need for a plan applies to all vessels and the size and type of vessel must be considered when formulating the plan. All information must be assembled as the requirement is a plan covering from berth to berth it therefore includes the period a pilot will be on board.


The following items should be considered when formulating the plan,

  • the condition and state of the vessel, stability, equipment, permissible draft, maneuvering data
  • special characteristics of the cargo its stowage and securing
  • provision of competent and well rest crew
  • up-to-date certificate and documents concerning vessel, crew, passengers and cargo
  • corrected and up-to-date charts in appropriate scale, navigational warnings and notices to mariners
  • up-to-date sailing directions, light lists and radio aid lists
  • mariners routing guides and passage planning charts
  • tide tables and current atlases
  • climatological, hydrographical, oceanographic and meteorological data
  • existing ship's routing and reporting systems, vessel traffic services and marine environmental protection measures
  • volume of traffic in transit areas
  • compulsary pilotage information, port information including availability of shore-based emergency equipment
  • procedure for the embarkation and the disembarkation of a pilot
  • details of the 'exchange of information' between the Bridge Team and the Pilot
  • any additional information useful to the vessel type and voyage or passage track


On the basis of the fullest possible appraisal a detailed voyage or passage plan should be prepared which should cover the entire voyage or passage from berth to berth, including those ares where the services of a pilot will be used,

  • this plan should include the plotting of the intended track on appropriate charts
  • the true course of the planned track should be marked
  • areas of danger, ship reporting systems, vessel traffic services and marine environment protection areas indicated
  • safe speed with regard to navigational hazards and draft limitations in relation to the available water depth should also be marked
  • limitations due to night passage, draft increases due to squat and heel on turns must be indicated
  • plot all course alterations with 'wheel over' points, speed and draft data
  • nearest ports of refuge and safe anchorages should also be listed

The Plan should be recorded in a notebook or computer disk available to the OOW's and Bridge Team at all times. It should be updated if and as more recent information becomes available. The Plan must be approved by the Master and signed off on prior to commencement of the voyage or passage. The Master will have to consider whether any particular circumstances introduces an unacceptable hazard to the safe conduct of the passage. The Master must further consider at which points of the voyage or passage there may be a need to utilize additional deck or engine personnel.


Having finalized the voyage or passage plan as soon as time of departure and estimated time of arrival can be determined with reasonable accuracy the voyage or passage plan should be executed in accordance with the plan including update changes made.


  • times of tide heights and flow
  • daytime versus nighttime passing of danger points
  • traffic conditions particularly at navigational focal points
  • meteorological conditions, speed reductions in poor visibility


  • the plan must be available at all times on the Bridge for reference
  • the progress of the vessel in accordance with the voyage or passage plan should be closely and continuously monitored.

Any changes made in the Plan should be made consistent with these 'Guidelines' and clearly marked and recorded

Several times during the year NAUTICAL LOG has had visitors searching for lifejacket instructions. With two just over Christmas we decided to publish something for everybody to see and read.
Choose a Coast Guard approved life-jacket and make sure it is undamaged. Make sure life-jackets are readily accessible, never locked away. Check the fit, there are adult, child and infant sizes, the correct one MUST be used. Choose bright colour life-jackets so as to be seen easily by Search and Rescue (SAR).Put your life-jacket ON BEFORE you leave the berth. Make sure you have a light and whistle attached AND they BOTH WORK.

Ships now operate under the International Management Code for Safe Operation of Ships and for Pollution Prevention (ISM Code).  Since this is a Post on Auditing NAUTICAL LOG, who is a Trained Auditor, will not go through the requirements as these can be found on the Internet and in your local nautical bookshop - you do have a bookshop hopefully as they are a dying breed.  There are two types of Audit an External Audit and an Internal Audit.

The External Audit consists of the Flag State or an outside Auditing Firm coming into the Company and going through all the Protocols, Procedures and associated Manuals.  They may also hold a drill simulating a situation in one of the Company's vessels and observe the results of the Shore Staff dealing with it.  NAUTICAL LOG has been through this experience with two very different Companies and believe me it is a long, difficult, trying day not made any easier by the subsequent debrief.  The External Auditor then prepares a Report which causes a…


Voyage Charter:

A contract (C/P) for hire of the use of a vessel to make a specific voyage between two identified terminal ports. The vessel will be carrying cargo or passengers for and on behalf of the Charterer's. The Charterer's pay for the the use of the ship either on the basis of a lump sum or in the case of cargo at a 'Freight Rate'. This freight rate is so much per tonne carried and delivered. This would not be the form of charter normally used in the business of yacht chartering.

Time Charter:

A contract (C/P) for the hire of the use of a vessel for a specified period of time and can take one of two basic forms,

* Basic Time Charter
* Demise or Bareboat Charter

The Basic Time Charter;

An agreement between the owner of a vessel, or if allowed the disponent owner, and a charterer who wishes to use the vessel for his own purposes without being responsible for the operation of neither the vessel or its day-to-day management.
Throughout the period of the charter the owner/…
