Vementry is also the name of a small farm on Mainland, Shetland, immediately south of the island. For this reason, it is sometimes referred to as the "Isle of Vementry". There is no ferry service to the island, although the shepherd on the mainland farm occasionally makes the short trip to work with stock on the island.
The Isle of Vementry is separated from the mainland Vementry by a narrow channel or "sound", consisting of Uyea Sound to the east and Cribba Sound to the west. Cribba Sound is famed for the quality of mussels produced at the mussel farms located there.
