    Designed by David Thomas in 1976 and built by Hunter Boats, the Sonata rapidly became a huge success. Dubbed as a pocket cruiser that could also race well, the direction of the Sonata Class has veered towards competitive one-design racing. The initial rules, developed in conjunction with the RYA, were designed to prevent “cheque-book” advantages and are, to this day, extremely strict regards measurement and permitted enhancements. The development of the class has been strictly monitored by the National Sonata Association, NSA, and the RYA to ensure that the boats are completely One Design.

    Although production of the National Sonata finished in 1990 with 479 boats being built, there is still a very active Class Association and keen racing and cruising fleets around the UK and abroad. At approximately 2 tonne all up, a Sonata is towable behind many of today’s vehicles relatively easily.

    Sadly, the Sonata is no longer built, but Hunter Boats made over 400 Sonatas during a period of 20 years. Many sailing clubs have adopted the Sonata as a one-design class and most of the major regattas have a Sonata start.
