Raymarine T70161 EV-400 Large Sail Autopilot Kit

Cruise - An Evolution Autopilot will take command

No fuss, easy to install and robust - the EV400 Evolution Sail Autopilot Kit combines Raymarine's autopilot expertise, FLIR Systems' R&D, and advanced aerospace guidance technology to create Evolution Ai control algorithms that deliver a new level of accurate autopilot control.

Key Features:

  • AutomagicTM - No lengthy calibration procedures to perform. No compass calibration required. Plug and play connections
  • Easy to install - Freedom from the restrictions of conventional heading sensors. EV sensor core can be installed above or below deck. Install upside-down or off the vessel's centre line.
  • Aerospace technology - 9-axis precision monitoring of pitch, roll, yaw and heading
  • Fuel efficient - Evolution autopilots steer so accurately they will save fuel and get you to your destination faster
SeaTalkng networking enables a single cable connection for power and data to the Evolution ACU (actuator control unit) and extended SeaTalkng and NMEA2000 networks.

Engineered for simplicity, Evolution AI Autopilots eliminate the need for complicated setup and calibration.

Once Evolution is installed, getting started is as easy as switching the autopilot on.

Thanks to the intelligent EV sensor core, the autopilot automatically evolves and adapts to your vessel's steering characteristics without any user adjustments.

This innovative breakthrough in autopilot intelligence enables Evolution autopilots to perceive their environment and then instantly calculate and evolve steering commands to maximize performance.

The result is precise and confident course keeping, regardless of vessel speed or sea conditions.
