| 07-10-1941 | AB Arthur Hall D/JX 208267 died. The circumstances of his death are not yet known but the Submarine Museum records indicate that he was a ‘buoy jumper’. He may have been drowned after falling in whilst either the Submarine was mooring to a buoy or slipping a mooring. He is noted as being buried in Londonderry, thus the Submarine may have been operating from that Port. |

In the immediate post-war period, ships were fitted with basic gyro compasses (typically AP5005) plus a transmitting magnetic or gyro-magnetic compass (ATMC5/AGMC6) for emergencies. Vertical attitude reference data came from wholly separate stabilisers (Gyro Stabiliser Type 1-12). Radio navaids were limited to the early Decca sets (QM10) and MF DF (FM12), with widespread use of astro navigation (by hand-held sextant), plus a 1930's vintage ARL table.
A selection of eclectic poetry and prose on various topics which will hopefully entertain, inspire and stimulate the mind.
