Stan Hugill, in one of his 'Bosun's Locker' articles in Spin magazine, stated that ships with large crews had little or no use for shanties for hauling and that whalers tended to have large crews. Nevertheless, even on such ships, shanties were still sung at the capstan and windlass. In his book 'Eighteen Months on a Greenland Whaler', published in New York in 1878 but relating to a whaling voyage in the late-1860s, Joseph P. Faulkner begins his narrative by describing his joining in the singing of a shanty but his ship was small and the shanty was sung at the capstan, so that does not carry the matter any further. I do not know if there are any other references to shantying later in the book.
