My grandfather took command of the Arctic Trapper in between the two events you cronicle. He was Louis Harvey, and he was one of three killed, but recovered, when it was lost off Ramsgate. The names of the unrecovered crew are listed on the memorial at Lowestoft, for seamen lost who crewed RNR vessels. You are welcome to contact me by email in the first instance,
timbertricks@btinternet.com I would be interested in having pictures or plans even of the vessel, her position when lost, etc. Regards Julian Saunders
