Hi Rainer
The Inshore campaign was an entirely different ball game to the Atlantic, but Meyer in U486 showed that success could be achieved in the Channel by determination - or was it luck ?
The T5 was known as Gnat ( an acronym of German Naval Acoustic Torpedo) and it had much early success. Two of my fellow officers had been victims. One to the first ever attack on HMS Lagan and the other on HMS Tweed. The towed noisemaker known as \"Foxer\", later superceded by \"Cat\" were not popular due to interference with Asdic and were seldom used. Anti-gnat tactics were used rather than acoustic decoys - a subject in itself.
Seraph\'s motors were upgraded and the battery power was increased, the gun was removed and the hull faired off. Most hull apertures were closed off and the free flood openings were reduced. One periscope,the radar and the periscope standards were removed and the conning tower was reduced to a minimum. The control surfaces were reduced and the propellers were changed to the T class which had a coarser pitch. The drag was reduced to less than half.
We seemto have wandered from the subject topic but it is all of interest. Incidently, you have not specified what you found incorrect in my origional contribution. Regards, RC
