Raymarine debuted Evolution autopilots, available from June 2013. The Evolution combines aerospace guidance technology with Raymarine’s marine autopilot expertise to deliver accurate autopilot control. Evolution has no need for a set-up compass swing or calibration and does not need to be adjusted to the boat to which it is fitted. It uses Evolution AI control algorithms which enable Evolution autopilots to perceive their environment and then calculate and evolve steering commands to maximize performance. At the heart of the Evolution autopilot system is the ultra-compact, EV sensor core, a 9-axis heading sensor and full function course computer in one. Around the same size as a typical marine GPS sensor, the EV sensor core can be either bracket-mounted or flush-mounted horizontally, and as it is built to IPX6 and IPX7 waterproofing and submersion standards, it can be installed above or below decks as space and practicality dictate.
The EV sensor core comes in two versions; EV-1 for Raymarine drive systems and EV-2 for drive-by-wire systems. EV-1 uses SeaTalkng cabling for a single power and data connection to an Actuator Control Unit (ACU) which provides power and signal only to a Raymarine hydraulic or mechanical autopilot drive system.
EV-2 uses a direct DeviceNet connection to a third party drive-by-wire system such as Teleflex Optimus 360, Volvo Penta IPS or ZF Pod Drive. Autopilot control is via the p70 or p70R control head. Setting-up an Evolution autopilot takes just 30 seconds; select the boat type – large power, small power, or sail; select the drive type – hydraulic, mechanical, or outboard; and choose the performance level – performance, cruise, or leisure,.
