Admirality or Imray would be what you used on your course I expect.
Admiralty Chart 1424 Ports On The South And West Coasts Of Corse (Corsica) - Admiralty - Mediterranean - Paper charts - Charts, Books & DVDs
Not sure what the scale on that is like compared to what you'd have used in Poole. There is a 1:12500, the link above is 1:60000
There is an Imray chart for Corsica but looks like its 1:255,000 which might lack the detail you want...
Possible there is a local Corsican chart which may or may not be more accurate or larger?Smaller? scale.
Imray basic symbols are mostly the same, but beware the colours of land are different! On admiralty charts land is yellow, 'beach' is green. Thats reversed on Imray (which actually makes sense as sand is yellow and land is sometimes green!) . Colours for water depth are also reversed on Imray.
Admiralty follows an international standard... but preumably there are Imray equivalents elsewhere too...?
