Description
Remote Mechanical Drive and Torque Analysis
Standard steering linkages on high-displacement yachts frequently experience cable stretch and manual helm slippage during autopilot engagement. The Octopus 12-Stroke Remote Linear Drive delivers 1000 pounds of thrust via a 38mm piston. This unit bypasses the primary helm for direct rudder control.
The drive integrates with 12V autopilot computers via a dedicated high-current clutch circuit for manual override. A 12-inch stroke length ensures full rudder travel for vessels up to 33000 pounds displacement. Heavy-duty internal gears provide long-term durability against mechanical fatigue in heavy following seas.
Strategic Vessel Application
Mandatory for sailing vessels and powerboats up to 33000 pounds requiring a remote-mounted linear drive.
