The city of Plymouth, Devon, England is bounded by Dartmoor to the north, the Hamoaze to the west, the open expanse of water called Plymouth Sound to the south and the river Plym to the east. The Cattewater is that stretch of water where the mouth of the river Plym merges with Plymouth Sound, just to the east of Sutton Pool. It is around this Pool that the manor of Sutton started, which grew to form the present day city. On the northern shore of this confluence of waters there was a rock outcrop, which it was claimed, had the appearance of a cat. This gave its name to this stretch of water and eventually the name of Cattedown to the adjoining wharves and commercial area. Apart from an occasional small oil tanker the area is now used mostly by fishing trawlers, yachts, and smaller pleasure
