INTEGRATED RUDDER & PROPULSION SYSTEMINTEGRATED RUDDER & PROPULSION SYSTEM

Promas integrates the propeller, a hub cap, a rudder bulb and the rudder itself into one hydrodynamically efficient entityefficient entity.

Propeller and rudder are designed together as a single unit. No hub vortex losses Better load distribution on propeller Better load distribution on propeller. Propulsive efficiency is increased by typically 4-8%.

Less fuel consumption Less environmental impact

L l t d h ll / l i ll d ib ti Less pressure pulse towards hull / low noise propeller and vibration. Improved low speed maneuverability. Simple and robust design. Almost as easy to install as a conventional propeller-rudder system. PROMAS LITE – Retrofit Existing Vessels
