DOEN or Twin Disc waterjets are currently in operation in over 25 countries throughout the Americas, Europe, and Asia, having gained a worldwide reputation for reliability, simplicity, performance, service, and support.
Today in the marine industry, waterjets are the preferred option for a wide range of commercial and pleasure craft, where high efficiency, superior manoeuvrability, shallow draft, low maintenance, total safety, and environmental issues are key requirements.
Globally, waterjets are now accepted as the preferred propulsion system for a wide variety of work boats, high speed patrol boats, fast passenger ferries, water taxis, dive boats, fishing vessels, landing craft, fire fighting vessels, oil spill recovery vessels, rescue vessels, crew boats, tenders, R.I.B's, pilot boats, survey vessels, parasailing boats, pleasure craft, and others.
