Ile de Sein location
ACLS65:
I fully agree with you that MarineTraffic gives usualy much more information but the site I found is dedicated to cable ships and seems to have data from yesterday (25/4/2011 9:57:28 UTC) with a location close to LKP.
The only problem is that they do not give a precise location.
I could only find pixel coordinates on a global world map by looking at the source code of the web page.
