The Dolphin 31 is a robust, British-built masthead sloop that emerged in the late 1970s as a sturdy alternative to the more ubiquitous mass-market cruisers of the era. Designed by John Sharp and primarily built by Carlisle & Williams, with later production associated with Offshore Yachts, the vessel was initially conceived with the charter market in mind. Although only approximately 55 units were produced, the model has garnered a reputation as a "powerful seaboat" according to Yachting Monthly, offering a level of build quality and interior volume that was highly competitive for its 31-foot length. With its traditional lines and heavy-duty construction, the Dolphin 31 remains a popular choice for coastal cruisers seeking a reliable, all-weather platform.
