The Pacer class of sailing dinghy, formerly known as the Puffin Pacer, was designed in the United Kingdom by Jack Holt. It was commissioned by Puffin Paints and Glues to be designed as yacht for use by families. It has since become a popular learning and racing dinghy in Australia, Canada, the Netherlands, India and the UK. The name was changed in the UK early 1970s, although Australia continued to use the name until 1989, when they followed the UK in dropping the "puffin" and chose the wedge-tailed shearwater as the boat's symbol.
