Incidentally, do you know that the meaning of a helm instruction changed direction? On the Titanic the instruction 'Hard a starboard' meant to turn *left* ASAP
Despite being ex Merch (eng, so bit of an excuse), I didn't know that, and assumed there had been a little error in the 1997 Titanic film when, in fact, the film maker had it correct (almost typed 'right' there and we all know how confusing that could be).
Senior BA trainer & Pruner pointed it out to me.
