Portsmouth Dockyard, Devonport Dockyard, Rosyth Dockyard, Gibraltar Dockyard, Lloyd Werft in Bremmerhaven, Marseille shipyard, they all have their own 'unique charm' about them, which i know from having done refits & maintenance periods in all of them over the last 56 years.
4 months in dry dock in Pompey certainly taught me how to 'skive' to an Olympic Standard. The crww didn't want ot be onboard and the 'dockies' certainly didn't want the crew around, so you sepnt most of the working day wandering around the dockyard, and Pompey Dcokyard is HUGE, going from 1 Fleet canteen to another. Most people used to carry some odd piece ship's of equipment with them as an 'excuse' for being around the Dockyard if anybody enquired!
Mind you, you certainly made up for all that time 'wasted' when you got to sea as it was more than 24/7, more like 48/7!
But would i change anything, no way Hosea, it taught me to live life for today and never to regret things you did, you can't change them afterwards but do learn from them.
