Thanks to Dazza for the idea.

The two Brians have identified lots of ships names in their posts - I know many companies had a theme for their names, but what were the themes? I did all but two trips with the one company, Harrison Line. Their ships were named after professions - Historian, Strategist, Custodian, Politician (the ship that foundered while full of whisky and the origin of the story for Whisky Galore), Linguist etc. But what was the theme at other companies?
Daley and Aspinall (and others) step to the fore.
