The Merlin Rocket is a 14 foot (4.3 m) dinghy sailed in the United Kingdom.
Most have a high batten allowing for a large roach in the sail.
The 'Merlin' was originally designed in 1945/6 by Jack Holt as a result of discussions among and commissioning by a syndicate of members, including Holt, of Ranelagh Sailing Club, on the Thames in London.
[3] The second Merlin and first production boat is now in the collection of the National Maritime Museum Cornwall having been presented to the museum by Beecher Moore, a sailing and business partner of Jack Holt and another member of the original commissioning syndicate.
[4] The 'Rocket' class was formed in 1949 when a group of Tynemouth sailors commissioned Wyche & Coppock of Nottingham, also known for their building of the Norfolk Punt, to design a half deck 14 ft. dinghy which had more sail area, narrower decks and was lighter than the Merlin.
