USE AND MAINTENANCE OF CHARTS.

A Mariner navigating on an uncorrected chart is courting disaster. The chart’s date reflects the latest Notice to Mariners used to update the chart; responsibility for maintaining it after this date lies with the user. The weekly Notice to Mariners contains information needed for maintaining charts. Radio broadcasts give advance notice of urgent corrections.

Local Notice to Mariners should be consulted for inshore areas. The navigator must develop a system to keep track of chart corrections and to ensure that the chart he/she is using is updated with the latest correction. A Summary of Corrections ,containing a cumulative listing ( Published bi-annually) of previously published Notice to Mariners corrections. Thus, to fully correct a chart whose edition date is several years old, the navigator needs only the Summary of Corrections for that region and the notices from that Summary forward; he/she does not need to obtain notices all the way back to the edition date. The mariner bears the responsibility for ensuring that his/her charts are the current edition. The fact that a new edition has been compiled and published often indicates that there have been extensive changes that cannot be made by hand corrections.

Using and Stowing Charts:- Use and stow charts carefully. Make permanent corrections to paper charts in ink so that they will not be inadvertently erased. Pencil in all other markings so that they can be easily erased without damaging the chart. When a voyage is completed, carefully erase the charts unless there has been a grounding or collision. In this case, preserve the charts without change because they will play a critical role in the investigation. When not in use, stow charts flat in their proper portfolio. Minimize their folding and properly index them for easy retrieval.

The index usually consists of a folio list of all the charts in each particular folio in sequential order. The list should include the full chart title, the chart number, including any designations i.e. Latticed charts or International charts, and date the chart was published.

e.g.

A separate index will be kept which lists the charts held on board in order of Chart Number. This is for use in chart correction. Against each entry of a chart number there should be the corresponding and sequential  number.

This allows the navigating officer to find charts, which require correcting, quickly and is also a good way of checking that no chart, requiring correction, is overlooked. When new charts or new editions of existing charts are published or charts are withdrawn, both lists should be amended accordingly.

Periodically the navigating officer should physically check the index actually agrees with what he/she has in each folio as charts can sometimes be put back in the wrong folio and a relieving officer may assume that the chart has been withdrawn.( This is very dangerous but has been known to happen (MIAB) and ignore any charts corrections for that chart, with disastrous results.

The index should also contain an up to date list of all the publications the vessel carries. The accuracy of this list can usually be checked by consulting the quarterly editions of Notice to Mariners, which list the latest editions of all Admiralty publications.

Chart Correction:- If a vessel is to be navigated safely for the duration of a voyage it is vital that the navigator has the most recent charts of the particular area and that these charts are fully corrected and up to date.

Charts may be identified by the following information.

(1)   The number of the chart (usually found, in heavy black type, at the top left and bottom right hand corners of a chart and on the outside cover)

(2)   The title of the chart (will be found in large bold type some where on the chart where it does not cover up important features on the chart, it is also found on the outside cover of the chart.

(3)   The date of publication of the chart (the date of original publication of the chart will be found at the bottom of the chart directly below the centre)

(4)   The date of publication of the latest edition of the chart if different from the above publication date (usually found on the outside of the chart above the title)

The Hydrographic Office publish a list of all charts and the latest editions annually in

The Catalogue of Admiralty Charts (NP 131)

New Charts:- These will be correct at the time of publication but the ship may receive the chart several weeks after this date. Upon receipt of the chart the navigator should check back through the weekly notices and find any corrections which apply to the chart since publication date. He /She should then enter these corrections on the chart starting with the one with the lowest number and proceed in numerical order to the latest correction applicable.

Once each correction has been done the notice number should be inserted, in ink, in the bottom left corner of the chart after the year. Subsequent notices should follow in numerical order.

e.g. 2010:- 139, 146, 197, 346, 501.

You should always remember to insert the notice after you have done a correction. The reason for this is simple- if you had forgotten to put down notice No.501 in the bottom left hand corner and gone on leave the new officer when it came to correcting this chart the next time a correction has been issued would not know if No 501 had been done or not.

New Editions:- Carry out the same procedure as above but when you have the chart corrected up to date of the latest weekly notices held onboard you must cancel the old edition.

This is usually done by writing in bold print across the front cover of the chart,

Cancelled Chart – Not to be used for navigation.

Most Masters now insist that old cancelled charts are removed from the bridge so that they cannot be used accidentally for navigation.

Both new charts and New Editions must be corrected for any temporary and preliminary notices which affect them and also any radio navigational warnings.

These may either be drawn on the chart in pencil or the relevant notice number pencilled in on the front cover of the chart to draw attention of anyone who uses the chart to the fact that there are other notices they must consult.

Chart Correction:- These days most large companies provide chart tracings when they send Weekly Notice to Mariners out to their vessels and there is no doubt that these make the job of correcting charts much easier as you can see exactly what you are doing.

However you should always use the tracings in conjunction with the actual text in the notice as it is definitive information.

Corrections should be made neatly as possible in magenta waterproof ink.

Symbols and abbreviations should conform to those indicated in Admiralty Chart 5011.

The notice No. ( and year if necessary) must be inserted in waterproof ink at the bottom left hand corner of the chart.

Before doing any correction make sure that the last notice No. in the bottom left hand corner agrees with the previous correction given in the text of the new notice being corrected.

Erasure should never be made however information which is no longer relevant should have crosses put through in water proof ink. The use of tippex is frowned upon because you may inadvertently cover the information on the chart.

When writing is to inserted on the chart great care must be taken the other information is not oblite...
