Thanks a lot for answering, Leo and Laurent.
Is the loss area same as the area which the British pilot Sgt. Vandewater gave? I don’t know, the grid system he/the keeper of the Leuchars ORB used wasn’t the same as that the (Royal) Observer Corps used at least during the BoB, which might have bene in general use in RAF, see http://www.echodelta.net/mbs/eng-grids.php, at least on first look The British Cassini Grid seemed to be the one used by Observer Corps during the BoB. Maybe Coastal Command used system similar to that of RN.

In fact I had supposed that the combat had taken place a bit more north and nearer to the Norwegian coast but that was only a pure guess. The area of loss is plausible, especially if the vessel was on the way to/from Southernmost Norway.

A bit more background info:
The vessel was Norwegian and there must have been something special in it because 235Sqn flew 11 sorties to find it on 1 March. Also one Hanpden/455 Sqn carried special patrol to find the vessel. And of course more planes may have been participated from other stations. Pilot of the O/235 Sqn was Sgt. Vandewater. If the claim was accepted, it was his only one, because he isn’t mentioned in Shores’ Aces High, AH Vol 2 or Those Other Eagles.

Thanks again
