Bruntons Propellers Ltd has been at the forefront of propeller design and manufacture for over one hundred years. The company, which is now part of the Stone Marine Group, produces propellers for commercial and naval vessels as well as yachts.

Autoprop was designed over twenty years ago and remains unique in being the world’s only auto-pitching feathering propeller, fitted to yachts by some of the worlds best known yachtsmen, including Sir Chay Blyth and Tom Cunliffe. As you can read on the ‘Latest News’ page Autoprop obviously has a very bright future, providing as it does the best possible all round performance for ‘green’ vessels as well as conventionally driven ones.
