    I would be grateful to receive for the help and advice of forum members regarding how I can confirm the longitude and latitude of the wreck of HMS Isis. The ship was sunk by a mine whilst it was on patrol in the English Channel.

    My Google searches have return two different locations.

    HMS Isis (D87) - Wikipedia
    Isis struck a mine and sank on 20 July 1944 at the position 49°27′N 0°41′W in channel 'T' off the western sector of the Normandy landing beaches.

    HMS Isis (D 87) of the Royal Navy - British Destroyer of the I class - Allied Warships of WWII - uboat.net
    The wreck is in 20 meters of water about 5 miles North-East of Courseulles-sur-Mer, Normandy in position 49.27.196N, 00.36.574W.

    Sadly neither cites a reference for their respective co-ordinates.

    Many thanks.

    Thank you Temujin.
    Any idea what an 'Oboe buoy' is?

    O Buoy must be a designation for a particular Buoy, others should have another letter of alphabet.

    UPDATE
    The wreck of the HMS Isis lies at 49° 27'N, 0° 37’W at a depth of approximately 29 metres was established definitively in July 2019 by members of the Southsea Sub-Aqua Club.
    See: Southsea Sub-Aqua Club - A Tale of Two Tugs in particular Section 7, p40 et seq.

    The two reports answer most of the questions I had about the sinking, location, anchorage plans, and buoy detail.
    The reports are well worth reading.
