The Sterling Class dates from the late 1950s and is considered the cruising version of the famous Twister Class, although with a slightly larger volume interior. Both are legendary designs from the board of Kim Holman. The Sterling Class, of which ninteen were built in total were constructed by Jack Upham of Brixham, Devon.

Sterlet, built for Dr Thomas Stratton of Fordingbridge in 1961 by J W Upham, is one of the early examples and has been maintained in exemplary condition. She originally sailed under RORC sail number 15 from her home port of Poole. In the early 1970s Mr & Mrs D H Graham-Weall of Parsons Pool House, Shaftesbury became the second owners, and registered Sterlet, Port of Registry Poole, official number 340030. Sterlet remained in their ownership, stationed in Poole through the 1970s and 1980s. In the current ownership Sterlet has been extensively cruised mostly on the South Coast and Solent. In 1999 a comprehensive refit was undertaken by Dolphin Quay Boatyard at Emsworth resulting in one of the best examples in her class.
