the Designer

Gary Mitchell

The youngest son of G Percy Mitchell. Percy was a famous builder of beautiful wooden boats of which he built over three hundred and sixty. They ranged from classic yachts to ferries and fishing boats. After his retirement in 1968 Gary took over the running of the yard in Portmellon, Cornwall and this led to me designing both wood and glass fibre vessels. Gary became the principal designer of the GM range of glass fibre heavy displacement fishing boats for Cygnus Marine of Falmouth, Cornwall and also many other yards. His designs are now in many parts of the UK and the world over.
