The Optima DUCT is a pre-swirl Energy Saving Device (ESD) designed to improve propeller performance and reduce fuel consumption. Mounted in front of the propeller, the Optima DUCT optimises the flow of the water before it reaches the blades of the propeller. This leads to smoother propulsion, lower energy losses, and measurable fuel savings.

Every vessel’s propeller operates in a non-uniform wake flow – water moves unevenly across the propeller disc. DMC’s Optima DUCT corrects this imbalance by redirecting the flow ahead of the propeller, ensuring that each blade operates under more uniform conditions.
This reduces rotational losses and increases thrust, allowing vessels to achieve the same speed with up to 6% less energy.

In short:
More thrust. Greater efficiency. Less fuel.
