Note: If you’re looking for Raymarine Evolution Autopilot Systems for Sale, both for Power and Sail Boats, we carry the complete line here: Raymarine Autopilot Systems For Sale

Having to maintain control of your boat at all times can grow tiring, especially if in rainy or foggy weather. That’s when the comfort of a warm, dry cabin can quickly overcome the thrill of cruising or sailing offshore.

In steps the award-winning Raymarine Evolution Autopilot – a smart and auto-correcting marine guidance system that will take over control and allow you to take it easy.

Raymarine autopilots can serve as spare helmsman, freeing you up to handle navigation or other chores if short-handed or on your own. And during long trips, a good marine autopilot is far more efficient than human hands, as a computerized brain ensures a never-swerving attention span… especially compared to a tired captain.

The continued development and growth of Raymarine’s autopilot algorithm and software provides you with an autopilot system that will:

  • Quickly and automatically calibrate
  • Monitor pitch, roll, yaw and heading with precision
  • Save you on fuel and power as it will stay tight on your chartplotter’s course
  • Perform smooth, crisp turns, even at high speeds
  • Maintain leisure performance, if preferred

A complete autopilot system consists of 1) the blackbox / computer processor /autopilot – the brains of the operation, 2) the drive unit, which serves as the muscle that keeps your vessel’s steering system on the right course and 3) the control head, that provides you with the user interface.

Raymarine has top-of-the-line components in each of these areas… I will help guide you as to which ones you’d need for your particular boat.

Raymarine Evolution Autopilots – EV-1 and EV-2 Sensor Cores with A.I., Monitor Vessel Motion in All Three Dimensions and Adjust

Raymarine EV-2 Sensor Core

The most valuable asset of an autopilot manufacturer is the algorithm they have developed and perfected over the course of many years.

Easy to use, install and highly-intelligent – the Raymarine Evolution autopilot combines Raymarine’s extensive autopilot expertise, FLIR Systems’ R&D, and advanced aerospace guidance technology to create artificial-intelligence (AI) control algorithms that deliver an extremely accurate autopilot control.

At the center of every Evolution system is the EV-1 sensor core, a 9-axis sensor that monitors vessel motion in all three dimensions, thanks to advanced solid-state sensors. Sealed in a an IPX6 waterproof and IPX7 submersible protective housing, you can install the EV-1 sensor core above or below deck.

Thanks to the constantly-learning A.I. in the EV-1 sensor core, your autopilot will evolve instantly as sea conditions and vessel dynamics change. Solid state sensor technology delivers dynamic accuracy to within 2 degrees in all conditions, and automatically compensates for on board magnetic fields.

Raymarine Autopilot Setup

EV-1 Setup

The EV-2 is designed for the latest drive-by-wire steering systems and connects directly to Raymarine’s SeaTalkng bus. EV-2 also has a dedicated CAN Bus port for direct connection to steer-by-wire steering systems such as ZF Pod Drives, Yamaha Helm Master, Volvo IPS* and SeaStar Solutions Optimus systems.

Raymarine EV2 Drive By Wire Propulsion

EV-2 Setup (no ACU)

The rugged Actuator/Autopilot Control Unit (ACU) in the Raymarine Evolution delivers reliable autopilot drive power and provides power to the SeaTalkng bus, and is available for different steering types, including wheel, tiller, hydraulic, linear, and rotary mechanical types.

Supported Drives

  • ACU-100 Wheel, tiller and 0.5 ltr Hydraulic

Cutting Edge Autopilot Software and Technology Found in Raymarine Evolution Systems

Hydro-Balance™ – Raymarine Evolution Autopilots come with Hydro-Balance™ Technology, the all new software update that delivers superior autopilot performance on boats with hydraulic steering, and particularly on boats with rudder reference-less steering and outboard motors.

*NEW Evolution R4 Performance-Tuned Software – R4 is the most significant update to Raymarine’s Evolution Autopilots. Major enhancements include:

  • Wind and Vessel Motion – Evolution’s intelligent EV sensor core fuses wind and vessel motion data to better determine true wind conditions
  • Extremely Stable Steer-to-Wind Angle – Evolution will steer to a set wind angle, sail downwind, or close hauled without risk of gybing or heading up into the wind
  • Superior Wind-Shift Detection – Evolution detects and automatically responds to true wind shifts, and prevents unnecessary trimming of sails
  • Crisp and Efficient Auto Tacking – Evolution filters out the effects of vessel movement for fast and precise Auto Tacking in all sea conditions
  • Evolution TrackIQ™, Intelligent Waypoint Tracking – Evolution TrackIQ™ technology removes the detrimental effects of vessel motion, while intelligently monitoring cross track error, speed, heading, and course over ground. The result is ultra precise waypoint tracking with little to no deviation from the course line.

All New Raymarine MFDs and Control Heads come with the Evolution R4 already pre-loaded, or you can download the software directly from Raymarine’s software downloads page.

Selecting the Proper Raymarine Drive Unit To Keep Your Steering System On Course

Raymarine Drive Unit

Raymarine Autopilots accommodate hydraulic, mechanical and power-assisted stern drive systems. The Raymarine drive unit is the part that interfaces with your vessel’s steering system to physically keep you on course.

Raymarine has a broad range of drive units to match almost any type of steering system.

Hydraulic Steering Systems

Hydraulic Drive Unit

Raymarine Evolution autopilots connect to hydraulic steering systems using a rugged hydraulic pump matched to the capacity of the hydraulic steering system.

If your system is hydraulic…

You’ll need to find out the size (in cc) of the hydraulic cylinder ram(s) mounted to the rudder or inboard engine boats, or to the drive unit on outboard engine boats. Your steering system documentation will have this information. If you cannot find it in the documentation, look on the cylinder ram itself for the brand and model number, and then use Raymarine’s hydraulic cylinder ram cross-reference guide, here.

Raymarine Evolution Autopilot Review / Feedback From Boaters

Reviews of Raymarine Evolution Autopilot

Looking through boating forums and other sources, you’ll find many happy boaters using Raymarine’s Evolution Autopilot System. Here are some Raymarine Evolution Autopilot reviews straight from the end users:

“I have installed the EV-200 (EV-1 course computer, ACU-200 drive controller and P70 display) last week. So far so good. NMEA 2000 backbone (not Seatalkng) with DeviceNet connectors. Garmin 740s chartplotter. 35 kt winds on San Francisco Bay. Kicked out once because of weather helm. Backed off of the mainsheet and it worked fine. Followed the Garmin track without any problems. VERY smooth turns and transitions. Have not tried a multi waypoint route, but expect no problems. No rudder reference installed (my current one has too low resistance – replacing it next week) but Raymarine says you don’t need one and they’re right…

In short, a fantastic unit and everything that I expected.”
