Many years ago I decided to choose the elite path towards becoming a skimmer, so never did the deep thing. However, as I was based at Dolphin for a prolonged period in FMT (eq) I became an 'honoury' bubble-ed. One night out I once called the tall black superstructure on a boat '...the fin' 8O This prompted a short/sharp lesson for me, and I remember the lad telling me; 'IT'S A CONNING TOWER, not a fin...! Its' sole use to house the scopes. Yanks call it a fin, WE call it a Conning Tower' This was during the P&O era. Now, my lad is currently on his 'launcher' course at Fas and yesterday referred to this tall black superstructure as a 'Fin'. So, have we gone Yank..?
