Tuhia he haere tonu mō tēnei wāhanga - I tīmata a De Neumann ki te whakawhanake i ngā whakaaro mō tētahi pūnaha whakahaere tauranga i a ia e rangatira ana i te HMRC "Vigilant". I whai ake enei whakaaro mai i te whakaaro ki nga huihuinga penei i te tukinga ohorere o te kaipuke moana e HMS "Divina" i te 1950, te tukinga o te kaipuke Norwegian "Baalbek" ki te Nore Army Fort i te 1953, me te waipuke kino o te Moana Te Tai Tokerau
i hua ai te waipuke o Canvey Island, Foulness me te Tai Rāwhiti i 1953. I roto i enei me etahi atu ahuatanga, ko te whakaoranga me te kohikohi matauranga i tino raru na te kore o te whakahau me te whakahaere pokapū, na te kore o te mohio ki te ahuatanga.
