SMW follows the Computer Aided Design System that provides detail design to every Propeller.

The system gives more selections and flexibility and provisions in propulsion system design. The design of each Propeller is carefully made according to commonly available data of Propeller like Diameter of Propeller, Pitch, and D.A.R (Disc Area Ratio) with respective to engine specification and vessel dimensions. All Propellers go through a rigorous inspection procedure prior to dispatch and detailed records are kept for the material specification and dimensions for future reference.
