Very Large scale wgs 84 electronic charts

Latest news


New Antares Charts for 2024: there are 69 new charts and 29 updated or expanded charts, making 693 in total, for the 2024 season.


Memory-Map ‘Marine’ charts (effectively UKHO charts) have also been updated for 2024. There are always many changes, even in Scottish waters —you should always update on your devices.


Shoal-draught boats, typically trailer-sailers. We are putting more emphasis on really sheltered and exciting locations that could be used by shoal-draught boats, especially those that can dry out. See OUR CHARTS Recent Developments

Please email ideas for such locations.


Setting up our charts in the new Memory-Map for All  navigating app is very simple on reasonably recent tablets, phones and computers. It is available for all platforms and makes things extremely straightforward






Most of those who choose not to use Memory-Map navigating software tend to be confident with technology.


If you are not confident with IT and would like someone to do everything for you then Steve Davis, who trades as London Chart Plotters may be your man. We have no formal relationship with Steve but he has helped a number of users in the past and his services are very inexpensive. He uses Marine Navigator apps and can set everything up for you remotely. He can also sell you a very nice reconditioned ruggedised 8” Samsung tablet, complete with all 850 UK and Ireland ‘UKHO’ charts, for £150 (see below left)!

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.

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 2024 edition is now available. It contains 69 new charts and 29 updated or expanded charts making 693 charts in total covering more than 685 locations.

Our charts run seamlessly with UKHO-type charts on PCs, Macs, iPads, iPhones and Android tablets and phones. There is a wide range of free apps/software available while ‘the best’ setup costs less than £50, including our charts and all UKHO-type charts for the UK and Ireland. Add in the Ordnance Survey walking maps too, if you wish!

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.
