Little remains of the wreck of the requisitioned trawler, the Sevra (HMT or HMS). There is some discussion as to which wreckage belongs to the Sevra and that of the AN2, both were very similar ships and both used as mine sweepers. They sank within a few hundred metres of each other, within two days or each other and were both flattened at the same time in 1949 by HMS Caldy. After the levelling, the records got mixed up.
Not an easy site to find, it can be easily missed underwater too, it is quite flat.
