Antares charts

Very Large scale wgs 84 electronic charts

Latest news


The 2020 edition remains the current edition. We expect it will be replaced in January by the 2022 edition with some 577 charts, 55 of which will be of new locations.


The 2021 surveying season is now over and we have some great new charts in the pipeline for next year (see illustration), as well as some important cautions—see below


Corrections to 2020 set:

· Cancellation of a correction! A professional survey at Lochcarron  identified an isolated 1.9m rock in an area we show as over 3m. We have been there since and confirmed that our depths were correct.

· Some serious fish farm debris has been reported in Loch Drumbuie

· A mussel farm is now blocking a channel in Loch Ailort

· Castle Bay, Loch Dunvegan. A cartographic error gives the impression that a rock drying 3.5m dries only 0.4m

Cautions arising from 2021 surveys:

· We have found a 1.2m rock in the centre of the entrance channel to the inner anchorage in Loch Risay, East Loch Roag, Lewis, where the UKHO charts shows 6.4m

· The rocky area marked by a beacon in the N entrance to Kirkibost Harbour, East Loch Roag, Lewis is significantly different in extent and shape from the UKHO chart and the CCC Imray Sailing Directions

· Loch Salainn in Enard Bay is described in the CCC Imray directions as probably the only swell free anchorage in Enard Bay—but it contains some serious uncharted rocks!

· We have found various other uncharted rocks in the minor Summer Isles

See corrections tab for details.


Our 2020 charts: There are 523 charts in the set: 62 new charts and many updates to older charts. There have been other big changes :

· our ‘Commentary’ is now on the face of each chart rather than in a separate document

· Memory-Map users can now download direct to the correct locations on their devices, greatly simplifying the setting up process


Setting up our charts in Memory-Map navigating software is now proving very simple on new tablets, phones and computers. On old ones you must first remove any old Antares Charts and ensure you have kept your software updated.


If anyone is really struggling to set up the charts despite having read the detailed instructions carefully they should get in touch. But please ensure you have read them carefully first! .



Most of those who choose not to use Memory-Map navigating software tend to be confident with technology but those who are not can seek help from Steve Davis, who trades as London Chart Plotters. We have no formal relationship with Steve but he has helped a number of users in the past and his services are very inexpensive.

Below is an image of part of our chart of the main channel at Arisaig, at low zoom, alongside the UKHO-type chart at maximum zoom. The charts are displayed on a PC with Memory-Map plotting software. The UKHO-type chart gives you the basics but our chart shows all the detail we found when we went exploring! Our chart can be zoomed a lot further and is complemented by charts of the north channel, the inner part of the loch and an even larger scale chart of the constriction in the main channel.

Ever been in a situation like the one above?  You found your way in when the sun was shining but how will you get out?  This is just one example where Antares large scale electronic charts might have made a real difference.

Memory-Map. We find the free Memory-Map plotting software coupled with UKHO-type charts to be the ideal platform for our charts. It costs £25 for a one year licence for the  UKHO-type UK and Ireland chart package (Marine Charts), which is excellent value.  You can run our charts seamlessly with the UKHO-type charts; and with side-by-side windows you can see your position on both. And you can run them all on iPhones, iPads and Android devices as well as PCs and Macs. See example of Arisaig below: all you need is the free Memory-Map app. You can also add in OS walking maps.



ANTARES CHARTS is a source of 'unofficial' very large scale electronic charts and related pilotage information created by yachtsmen for yachtsmen.

Focusing on the West Coast of Scotland it is aimed at experienced navigators, to supplement information available from more authoritative providers.

The UK’s official surveying and charting authorities have not resurveyed many of the more interesting channels and anchorages of the West of Scotland since the advent of satellite positioning and often do not publish charts to a sufficiently large scale to meet the needs of the more adventurous yachtsman.

Our 523 charts can run seamlessly with UKHO-type charts on PCs, Macs, iPads, iPhones and Android tablets and phones. There is a wide range of free software available while ‘the best’ setup costs c. £40, including our charts and all UKHO-type charts for the UK and Ireland.

WARNING:  All information described in this website has been obtained by enthusiasts without formal training.  It must be used with great care and entirely at your own risk. See the risk factors outlined under ‘Making the charts’ and ‘Using the charts’.

We welcome contact from users of the charts.  Please let us know of any errors or inaccuracies you find.  Please also let us have your thoughts on presentational issues, locations for future surveys and other material you think we could provide that you would find useful.  As this is an unpaid, part time activity we do not undertake to respond to all correspondence on a timely basis but will endeavour to do so.
