For the ultimate in speed, manoeuvrability, efficiency and dependability, nothing matches Twin Disc Arneson Surface Drives. Their surface-piercing propeller design reduces underwater drag by 50% compared to conventional submerged propeller drive systems. The only surfaces to contact the water are the propeller blades and a protective skeg. This results in higher overall speed, quicker acceleration and a better payload-to-power ratio. And 50% less drag significantly improves fuel economy while lowering operating costs.
For those seeking the ultimate in speed, manoeuvrability, efficiency and dependability, nothing matches the Arneson Surface Drive concept.
Thousands of these drives have been operating successfully for many years on pleasure craft, commercial and military applications throughout the world.
Trimmable Propeller Shaft
The propeller shaft is vertically adjustable, allowing selection of the optimum thrust angle for varying load and sea conditions.
Positive Thrust Steering
Unlike conventional systems that vector prop thrust off of a rudder, the Arneson Surface Drive angles in the direction of motion, maximizing steering control and response.
Propellers are located aft, behind the hull, increasing steering leverage and improving manoeuvrability at all speeds.
Shallow Water Capabilities
The drive has a trimmable propeller shaft and no fixed underwater appendages, requiring significantly less draft than conventionally powered hulls.
