Arneson Surface Drive

Ultimate Speed and Fuel Efficiency

No other marine surface drives match the speed, efficiency and dependability of Twin Disc Arneson Surface Drives. Their surface-piercing propeller design cuts underwater drag 50% over conventional submerged propeller systems, cutting fuel use and costs. Only the propeller blades and a protective skeg contact the water—for quicker acceleration, higher speed and a better payload-to-power ratio.

Rolla Propeller

Top Technology for Top Performance

Computational fluid dynamic (CFD) hull analysis, along with countless trials and thousands of successful applications, gives Rolla an unmatched technology database for designing world-renowned propellers. A dedicated pattern for each application assures reliability, performance and longevity. Rolla propellers can be designed to meet any classification register, including Lloyd’s Register, ABS, RINA and others.

Rolla fully submerged propellers start with software analysis of all possible shapes and inputs, including diameter, number of blades, skew, rake and more. We determine the best possible design for the application, then use CFD to fine-tune the propeller load and detect any potential cavitation or flow problems.

Rolla surface-piercing propellers are designed through systematic tunnel testing. We consider the lateral, vertical and horizontal thrusts combined with different diameter and pitch options to determine the optimum propeller for each application.
