Product Description

Raymarine EV-400 Sail Autopilot without Drive Unit


Raymarine combines its autopilot expertise with aerospace guidance technology to eliminate the need for a setup compass swing or calibration and the EV-400 doesn’t need to be adjusted to the boat in which it is installed. This innovative breakthrough in autopilot intelligence uses Evolution AiTM control algorithms that give the autopilot the ability to perceive its environment and instantly calculate and evolve steering commands for maximum performance. This results in precise course-keeping regardless of vessel speed or sea conditions.

The EV-400 Sail Autopilot is designed for large sailboats and is compatible with Type 2 and Type 3 Raymarine hydraulic, linear and rotary mechanical drives. You purchase drive units separately depending on your boat’s displacement and steering type. The system is easy to install and it works with the p70 control head. Setting up the EV-400 takes mere seconds. Select the large sailboat followed by the drive type—hydraulic or mechanical—and finally choose the performance level. The p70 offers one- and 10-degree course change push buttons for ease of use.

Key Features:

EV Sensor core: The heart of the evolution system is the ultra-compact EV Sensor core, a nine-axis heading sensor and full Function course computer that monitors pitch, yaw, roll and heading.

Compact Size: Because it’s about the same size as a typical marine GPS sensor, the EV sensor core can be bracket- or flush-mounted horizontally. It’s IPX6 water-resistant so the sensor can be installed above or below deck.

SeaTalkng cabling: This convenient feature provides a single power and data connection to the SeaTalkng bus and the Actuator Control Unit (ACU) that attaches to the same bus to provide power and signal to a Raymarine hydraulic or mechanical autopilot system.

AutomagicTM: No lengthy calibration procedures or compass calibration are required to set up. This is true plug and play installation.

Super Accurate: Delivers accuracy to within 2 degrees in all conditions.

Automatically Adjusts: Auto compensation for on board magnetic fields and reliable heading accuracy in northern and southern extremes.

Plays Well With Others: Fast, reliable heading data for MARPA, radar overlay and heading modes on Raymarine aSeries, cSeries, eSeries or gS Series multifunction displays.

Warranty: Three years (with product registration)
