All Cautions and Amendments will be listed here but if significant errors are found in any of our charts we will make replacements available to registered users. For printable versions of each year’s Cautions and Corrections see below.


The following correction and cautions relate to our current 2020 charts (please let us know if/when you find more issues!): 


April 2020: Correction: Lochcarron: a recent professional survey has revealed a 1.9m rock in an area we show as over 3m and close to a 2.8m sounding. The position is 57deg 23.78N, 5deg 28.95W.


August 2020: New hazard: Loch Drumbuie: an Antares Charts subscriber recently reported the following serious underwater hazard:  a heavy pile of fish farm debris comprising nets, steel poles and ropes - all well enough secured to the bottom to hold our vessel on a vertical rode against 30knots! Location, roughly on the 15m contour to the north of the Loch: 56° 39.428' N  5° 55.733' W.


September 2020: Caution: Loch Ailort Entrance Channels:we understand that there is now a mussel farm to the NE of En Bairneach that blocks the  E end of the channel between En Bairneach and En nan Trom. It is therefore necessary to pass S of En Bairneach when entering or leaving the inner loch.


The following cautions arise from 2021 surveys that will result in new charts for 2022:


May 2021: Caution: Loch Risay, East Loch Roag, West Lewis: UKHO chart 2515 shows a 6.4m sounding in the entrance to the inner anchorage in Loch Risay. We found a rock of 1.2m exactly under this 6.4m sounding. Our new chart will be published next year but for now the only safe way of entering or leaving is to ensure enough height of tide to be able to pass over the rock, remembering that high atmospheric pressure can reduce the water level by 30cm or more.


May 2021: Caution: North entrance to Kirkibost Harbour, East Loch Roag, West Lewis: the rocky area around the perch in the channel extends significantly further to the N than indicated on UKHO chart 2515 or in the CCC Imray Sailing Directions: there is a 1m ledge 50m NW of the perch, roughly half way between the E and W HW lines. To enter the harbour it is necessary to steer a course due S, first passing 50m off the perch on the Bernera shore (W shore) and then passing 50m to the W of the perch in the channel, a little further on. The Bernera shore shelves steadily, without unpredictable hazards.

The 2018 set of 461 charts has been superseded by the 2020 set of 523 charts. We recommend that you no longer use the 2018 or earlier sets: many of the 2018 charts have been subject to minor changes that make continued use of the originals undesirable.


Many of our cautions have led to corrections to UKHO charts but in case you have older official charts the full lists are available below:

NB  Hydrographic surveying and cartography are not precise sciences. There will be errors and misrepresentations on our charts just as there are on others’ charts. Do read the sections on ’Making the charts’, ’Using the charts’ and the ’Conditions’. Take great care at all times but especially if away from the routes described by the pilot books.
