Why buy Allen?
The Allen brothers, Tony and Glenn, started their business back in 1956 with a vision of performance sailing hardware driven by their passion for sailing and their love of engineering, innovation and technology. The first fittings, which they designed and made for their own race boats, were such an improvement on everything then in use, that they were persuaded to set up full production to meet the demand of the growing dinghy sailing market. The principle of concept to completion still holds true and the company has grown in the past 60 plus years to become a major exporter, selling high-performance sailing hardware to the World. R&D, design, prototyping, toolmaking and production takes place at the Allen factory in Southminster, Essex, UK, which is now run by Tony Allen’s daughter Liz Adams along with a highly skilled and dedicated Management Team.
