PROPULSION



Complete Solutions for Better-Running Boats

Twin Disc propulsion products are engineered to increase efficiency and ease of operation. Accessories and options make it easy to customize solutions for your vessel.


ARNESON SURFACE DRIVES

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 PROPELLERS

Top Technology for Top Performance

Twin Disc propulsion products are engineered to increase efficiency and ease of operation. Accessories and options make it easy to customize solutions for your vessel.

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.


SAILDRIVESSmooth, Versatile Propulsion

The SeaProp60 propulsion system, for sailboats with engines rated up to 56 kW (75 hp) @ 3600 rpm, benefits sailboat manufacturers and operators.

Boat builders can say goodbye to the propeller shaft, its mechanisms and related alignment issues. The SeaProp60's smaller footprint and mounting flexibility--facing forward or aft, with no shaft angle or aperture constraints--expand engine placement options.

Boat operators can say hello to quieter, smoother propulsion. Thrust is parallel to the boat's waterline, unlike the downward angle of a conventional shaft, increasing propeller efficiency. The SeaProp60 can be matched with fixed or folding propellers.
