Admiral Collingwood (of Trafalgar fame - 1805?) wrote in his diaries of having bagpipes & fiddles on board - and a pipemaker (but the rats ate the bags). They had a "band" which played for the sailors to dance hornpipes to, for about an hour - 6-7 in the evening (can't remember which watch that is).
Yes it was supposed to help scurvy.

Though we don't know exactly, they were probably what is known today as Border or Lowland pipes.
