Malc Posted March 6, 2023 Share Posted March 6, 2023 Looking at navi Web app and I see abbreviations such as S, M and R and that's easy enough, sand mud and rock. However I am confused with two locations one is MS.G.SH and the other M.S.G/R (mud sand gravel/rock perhaps)? Quote Link to comment Share on other sites More sharing options...

Andy135 Posted March 6, 2023 Share Posted March 6, 2023 On the Navionics web app you can click the letters, then click the blue ? icon to the right of the cross-hairs, then expand the Seabed Area line to reveal the details. It won't give a full description of each of the words in the abbreviation, but will list the major component. JDP 1 Quote Link to comment Share on other sites More sharing options...

I like to carry several different brands of charts on board to cross reference against each other when navigating in and out of the same river.

You need Chart 5011, which is the full list of annotations and abbreviation used on admiralty charts. The PDF is too large to attach here, the sea bed abbreviations start on page 25, and the pdf is available for download here, Chart 5011 8th Edition Quote Link to comment Share on other sites More sharing options...

I did that, however I was using our tablet and I now realise I haven't logged in on it 🤪 Quote Link to comment Share on other sites More sharing options...
