SOUTHERN POWER FAVOURITES

KOMPAKT SERIES

DOEN’s latest impeller and compact hydrodynamic designed intake duct are used across these models to underpin excellent performance and load-carrying capacity. These models all use the transom-mount method that was pioneered by Doen Waterjets. This is a bespoke feature across the range. The transom mounting provides a high-strength, simple, precise and low-cost installation for all types of hull design and construction.

A hull insert is used to form the initial part of the intake tunnel. It also provides a strong and leak- proof mounting face for the waterjet so that it can be quickly and simply bolted onto the hull. The hull insert also provides a great deal of flexibility for the longitudinal position of waterjet in the hull, which is invaluable to designers who have to deal with confined inboard space.

optima

OPTIMA SERIES

This group of waterjets all use an optimised design intake duct which is made entirely from hull-matching material. This results in an extremely strong and lightweight structure.  The installation method provides a high-strength, simple and precise integration of the intake duct into all types of hull design and construction.

Optima Series waterjets use Doen’s latest impeller technology to deliver mixed flow type, high-speed performance, within an axial build.  This approach – together with hydrodynamically advanced intake geometry – combines the key benefits of exceptional high-speed performance with superior cavitation margins and excellent efficiency at lower speeds and cruise conditions together with extended component life and simple maintenance. This means that hence the cost of ongoing ownership is lower.

ELECTRONIC CONTROL SYSTEM

From RCS, ECS Lite to ECS400 and eDock

Combining the reverse and steering functions into one rugged system, waterjet propulsion provides for excellent manoeuvrability at high speeds in jet boats as well as low speeds. Waterjet propulsion  provides for full manoeuvrability even when the boat is stationary.

Doen Waterjets offers a complete range of dedicated waterjet controls. These range from simple hydro-mechanical to sophisticated fully integrated electronic systems. Each waterjet model has several options to best suit different application and budget requirements.
