The HamiltonJet parent company, CWF Hamilton & Co Ltd, was formed in 1939, centred on the workshop at Irishman Creek Station. For the next 50 years the company pursued a policy of planned diversification, a natural progression from the effective innovation and expertise initiated by the founder Sir William Hamilton.
It has only been in the last 25 years that CWF Hamilton & Co has focussed solely on the waterjet side of its business through HamiltonJet and Hamilton Marine.
HamiltonJet grew out of a combination of CWF Hamilton Engineering and CWF Hamilton Marine, the two main subsidiary companies in the Hamilton Group.
