Gunkholing ?1995

[Baker, John]

        Well, www.gunkhole.org says that gunkhole as a noun means "a small, sheltered cove for anchoring small watercraft" and as an intransitive verb means "to make a series of short pleasure trips by boat, as from island to island."  There was a 1984 book by Al and Jo B. Cummings called Gunkholing in the San Juans, but I bet the term goes back earlier than that.  I had never heard it before.
