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 relates to our current 2024 charts (please let us know if/when you find more issues!): 

 

Correction: AC 5636E Loch a’Choire, Loch Linnhe, edition 1. We understand that the Boathouse restaurant has reopened and have heard very good reviews! Opening hours vary through the season so check on their website and book as early as possible! We understand that there are also six new visitor buoys.

 

Correction: AC 5538A Ardbeg and Loch an t-Sailein, edition 3. A 1.3m rock has been identified within the 5m contour at 55deg 38.074’N, 006deg 05.277’W, 60m S of the inner end of the S route through the E reef referred to on our chart. An updated chart, with further additional detail, will be published in our 2025 set.

 

The following cautions arose from 2024 surveys that will result in new charts for 2025:

 

Correction and Caution: AC 5720E Churchton Bay, Raasay, edition 1. There are now pontoons suitable for yachts to lie alongside in the inner. The mooring buoys at the E end of the outer bay have been removed. We have had reports of a pipeline crossing the outer bay but have not yet been able to establish its position. Further information will be shown on an updated chart in our 2025 set.

 

Caution: South Shuna Bay, Shuna Sound. There is a 0.3m uncharted rock close to the middle of the entrance to this little bay. 56deg 12.345’N, 005deg 36.870’W.

 

Caution: Entrance channel to Balvicar. There is a 2.6m rocky patch in the centre of the channel, very close to where the UKHO chart shows a 3m spot depth at 56deg 17.414’N, 005deg 35.879’W. This will not affect most vessels but we had assumed that the seabed is predominantly mud in this area and it was a surprise to find a rock where a larger vessel might wish to anchor.

 

Caution: Eilean an Fheoir, Loch Scridain, W Mull. The anchor symbol on UKHO chart 2771 is over bare rock: a better place for it would be 100m SW. Sgeir na Rad dries only 1.7m and not 2.3m as shown on chart 2771. Whilst an error in the right direction, it was of some concern that the rock was not visible when it ‘should have been’.

 

Caution: Bendoran Anchorage, Loch na Lathaich, Bunessan. We think the wreck of the 90m vessel ‘Ostende’ should be depicted rather better on official charts. In particular, there are depth discrepancies between UKHO charts 2771 and 2617, both at 1:25,000. We think 2617 is better, although the wreck extends some 50m further to the SW than the dotted area with a 2m depth in it suggests. It should be noted that there was a massive explosion on the vessel and while we understand that efforts have been made to clear much of the debris there is a risk that some may remain so that use of a tripping line would be wise.

 

Caution: Tarbet Bay, Loch Nevis. There is a rock of 1.9m on the bar across the entrance to the bay that is not shown on UKHO chart 2541-5. It is at 56deg 58.417’N, 005deg 38.195’W. It is under the ‘9’ of the 4.9m depth on chart 2541-5. The 1.9m feature is very small but there are depths of 2.4m to 2.7m over a large area around it. There are also depths of less than indicated on BA2541-5 a little further to the W,lbeit all over 3m.

 

Caution: Bogha Don, Loch Nevis. A 0.9m rock, not shown on UKHO chart 2541, lies some 20m outside the dotted line of uncertainty on the official chart and almost on the 10m contour, to the SE of Bogha Don. This is almost 100m of the beacon, which seems like a very long way, but you must give it a significantly greater berth still!

 

Caution: Channels either side of Pladda Island in Loch na Mile, Craighouse. There is a 1.9m rock in the middle of what appears to be the channel E of Pladda on UKHO chart 2396. We recommend that this channel should not be used by deeper draught vessels without our chart, which will be included in the 2025 set. To the W of Pladda and to the E of Foul Point (named thus for very good reason!) all vessels should respect the dotted line of uncertainty on UKHO chart 2396! A N-S line through the 4.3m spot depth gives a good guide to where the deepest water is to be found.

 

Caution: Scarisdale Rocks, Loch na Keal, W Mull. Both UKHO charts 2652 and 2171 significantly overstate the depths between Gallie Rocks and Scarisdale Point. Adverse conditions prevented us from establishing depths with certainty but there is at least one patch of 2.2m. Close to LWS, deeper draught vessels should approach the anchorage from the N of Gallie Rocks.

 

Caution: Eorsa Island, Loch na Keal, W Mull. The isolated drying rock shown off the NE of Eorsa Island, also shown on 1:25,000 OS maps, does not exist! Instead, there are rocks and rocky patches of seabed further S. We advise waiting for our chart to be published in January 2025 before visiting.

 

Caution: Camas Chil Mhalieu, Loch Linnhe. There is a rather curious feature on UKHO chart 2379 on the W side of this bay: a 4.2m spot depth with a solid black contour around it. We could find no trace of anything untoward in this area: it seemed to be just smooth sediment suitable for anchoring. However, further N, running approx. ESE from the 0.9m spot depth, there is a spit of no more than about 0.4m extending well beyond the 2m contour.

 

Caution: Douran Rocks, Gruinard Bay, Ullapool. The rocks are shown as drying 2.9m but actually dry only 1.4m: if you can’t see them don’t be surprised! But running SE from the position marked on UKHO chart 2500 is a rocky reef running half way to the shore on which we found least depths of 2.5m. This is not a good place to anchor.

 

Caution: Balnahard Bay, N Colonsay. This information has been reported to us and not independently verified. UKHO chart 2169 shows a 1m permanently dry rock off the main reef to the N of the bay. Don’t be tempted to think you can pass close outside the outermost rock you can see: you can’t! This rock dries but is normally covered (we don’t have the exact depth) but, to compound the problem, there is a permanently dry rock towards the outer edge of the green drying reef that is not shown on the UKHO chart. This little trap was reported to have caught out at least one unsuspecting yacht.

 

 

The 2023 set of charts has been superseded by the 2024 set of 693 charts of more than 685 locations. We recommend that you no longer use the 2023 or earlier sets: many of the 2023 charts have been subject to changes that make continued use of the originals undesirable.

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.
