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!): 


June 2021 cancellation of an April 2020 Correction: Lochcarron: a professional survey reported 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. We have since confirmed that our original depths were correct!


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.


June 2021: Correction: Chart 5726A, edition 2: Castle Bay, Loch Dunvegan: in the northern part of the bay there is a green drying area with a double black line around its perimeter (what the Ordnance Survey describes as ‘Ornament’!!!). This has a drying 0.4m depth beside it. This was a computer generated depth and, while it is correct, it is misleading as the centre of the rock, that we weren’t able to pass over, is estimated to be drying 3.5m. NB  OS ‘Ornament’ of this sort should always be avoided.



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.


June 2021: Caution: Loch Salainn, Enard Bay. There is a large rocky area with least depth of 1.1m adjacent to the prominent drying rock and partly obstructing the channel into the loch. There is also a rock with least depth of 2.2m exactly where yachts would be likely to anchor. An image of a draft chart is reproduced below.


June 2021: Caution: Minor Summer Isles. We have also sent H notices to the UKHO in connection with three rocks in anchorages off Priest Island, Carn Skerries (west side) and in the channel to the east of Carn Deas. These have least depths of 3.9m, 2.4m and 2.6m respectively, are not in the obvious anchoring spots and so are unlikely to trouble most yachts, very few of whom visit these remote anchorages. Full charts will be published in early 2022.


July 2021: Caution: Upper Loch Nevis. We have investigated the head of Loch Nevis and will be publishing charts of the South Head and ‘Pier Bay’ in 2022. The CCC Imray Sailing Directions suggest anchoring in either the N or S branches at the Head. The N branch looks very suitable—we have not done a detailed survey but it appears to have a large flat area but at 15m (+ tide) and not the lesser depths implied by other charts. The S head has very steeply shelving sides—in places 1m down for 2.5m horizontally! - and we suggest you should not use it other than in very settled conditions.

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.
