Offering flexibility in vessel design and machinery layout

Mermaid pods offer flexibility in vessel design and machinery layout. They combine the functions of a propulsion motor, main propeller, rudder and stern thruster in a single unit. The integrated electric motor drives the shaft, saving space on board and eliminates the need for a gearbox. The propeller is a fixed pitch high skew design for low noise and vibration. It can be supplied as a monobloc or with separately bolted blades, that can be simply changed in the event of damage. All seals are environmentally friendly, with no oil release in the event of a failure.
