Hugh Agnew Yacht Instruments

Founders Richard Tinley and Hugh Agnew, have over 60 years combined experience in race navigation, marine instrument design, troubleshooting, fitting, and repair.

Richard served his apprenticeship at B&G before going on to run the service department there. Then, after 7 years in the Caribbean installing electronics on large yachts, he founded Tinley Electronics, and the independent, B&G service, running this for 20 years and rebuilding many thousands of instrument systems. He is also a gifted electronics and software designer and has made many custom products used in America’s Cup projects and on Superyachts worldwide.

Hugh, a Cambridge mathematician, and oceanographer spent his career building navigation systems for the offshore, military, and yachting industries. He developed the first TV tracking used for America’s Cup in Fremantle in 1987, was the inventor of the Yeoman plotter, and developed the first telephone-based car navigation system. Throughout he has sailed professionally as a navigator and continues to do this on some of the world’s largest and fastest yachts.





All A+T yacht instruments are made with uncompromised attention to detail and an obsession with testing. Every instrument made is submerged in 1m of water for 24 hours and run in the oven at 75 Deg C before shipping.

Design, assembly, and testing are all done in Lymington, UK where clients are welcome to visit, give feedback and new ideas on future directions.
