In the verison I know the last bit of the first verse goes -The shipping master sez to me get on your blue DB's, We'll have none of your lime-juice touches in the Champion of the Seas.
Blue DB's refers to the blue double-breasted (DB) jacket worn by sailors. Why would a ships master ask a recruit to get on his knees??? Lime juice touches makes sense - English sailors were called 'Limeys', by the Americans in particular. Lime juice touches would be refering to what this shipping master thought was the 'malingering' way the English got a daily lime ration. I have never heard 'loungers' used in this context and suspect it is a more modern expression.
Makes even more sense when you read the following about the Blackball line -
"The ships were famous for their fast passage and excellent seamanship. However, they were also famed for their fighting mates and the brutal treatment of seamen. (Western Ocean seamen were called "Packet Rats"). Many ships bore the name "bloodboat". Most of the seamen hailed from New York or were Liverpool-Irish."
