Hi Phil. Back to source - Sharp/Short only had one verse and chorus, so yes, 'deep-water ship' does appear to be another I borrowed way back in '79. I did nick it as a floater and not make it up, but the source now eludes me. Sorry. (Now we've done it, I much prefer the reconstructed set that came from an amalgam of Short, Scott and McPherson as recorded on vol.3 of Short Sharp Shanties - thanks to Lighter's work, it also firmly locates the ship and her times).
