Detailed description

The Raymarine Evolution Tiller Pilot, part number T70249, is an integrated solution designed for sailboats equipped with a tiller. This system combines the ACU-100 control unit, the EV-1 sensor, and a tiller drive mechanism, providing precise heading assistance for coastal and offshore navigation. It is intended for small to medium-sized boats.

Evolution system architecture

The core of this system is the EV-1 sensor, a central component of Raymarine’s Evolution range. This sensor integrates a compass, a gyroscope, and an accelerometer into a single unit, simplifying installation and eliminating the need for complex calibration. The ACU-100 control unit is specifically sized for low-power tiller drives, distinguishing it from the ACU-200 or ACU-400 models, which are designed for higher-power hydraulic or linear actuators suitable for larger vessels.

Connectivity and interface requirements

The system uses Raymarine’s SeaTalk NG network for communication between its components and with other marine electronic equipment. For control and display, the T70249 autopilot requires a compatible Raymarine multifunction display (MFD) or a dedicated autopilot control head. This architecture allows flexible integration into an existing navigation system, providing users with precise heading control via an interface tailored to their needs.

« Technical analysis: Raymarine Evolution Tiller Pilot ACU-100 with Tiller Drive »

The Raymarine Evolution Tiller Pilot with ACU-100 and Tiller Drive is the ideal autopilot solution for tiller-steered sailboats of small to medium size. Its practical value lies in freeing the helmsman for other onboard tasks while maintaining a stable and precise heading, even in rough sea conditions thanks to the EV-1 sensor. This system is particularly relevant for single-handed sailing or reduced crews, providing valuable assistance for long crossings or under-sail manoeuvres.

Installation is simplified by the SeaTalk NG architecture and the EV-1 sensor’s automatic calibration, which requires no complex commissioning procedures. The Tiller Drive is typically mounted on the transom or in the cockpit, with a direct connection to the tiller. However, a Raymarine MFD or a dedicated pilot control unit (such as a p70s) is required to interact with the system, which is a constraint to anticipate when planning the installation. The ACU-100 is designed for moderate current consumption, suitable for tiller drive motors, but would not be suitable for high-power hydraulic rams.

Compared to older solutions or standalone tiller pilot systems, the Evolution system offers superior piloting intelligence thanks to the Evolution AI algorithm, which learns and adapts to the boat’s characteristics and sea conditions. This results in optimized energy consumption and more effective course-keeping. Its main limitation is its restriction to tiller steering and boats whose drive power requirements are compatible with the ACU-100. For larger vessels or hydraulic steering systems, the ACU-200, ACU-300, or ACU-400 units should be considered.

Frequently Asked Questions

Need help? Contact us

What are the main components included in the Raymarine Evolution Tiller Pilot T70249 pack?

The T70249 pack includes the essential components for a tiller autopilot system:

The ACU-100 control drive unit (CDU).The EV-1 sensor, which integrates a compass, gyroscope, and accelerometer.A tiller drive mechanism.Note that a Raymarine multifunction display (MFD) or a dedicated autopilot control head is required for system control.

Is this autopilot compatible with all types of boats?

No, the Raymarine Evolution Tiller Pilot T70249 autopilot is specifically designed for sailboats equipped with a tiller. It is ideal for small to medium-sized boats.

Is it possible to use this autopilot without a Raymarine multifunction display (MFD)?

No, for control and display of information, the T70249 autopilot requires a compatible Raymarine multifunction display (MFD) or a dedicated autopilot control head. These interfaces are essential for system interaction.

Does the EV-1 sensor require complex calibration during installation?

No, the EV-1 sensor is a central component of the Evolution range that greatly simplifies installation. It integrates a compass, a gyroscope, and an accelerometer into a single unit, eliminating the need for complex calibration.

What type of network is used for communication between the different elements of the system?

The Raymarine Evolution Tiller Pilot T70249 autopilot system uses Raymarine's SeaTalk NG network. This network enables seamless communication between the EV-1 sensor, the ACU-100 unit, and other compatible marine electronic equipment.

Can the ACU-100 actuator control unit be used with hydraulic or linear actuators?

No, the ACU-100 actuator control unit is specifically designed for low-power tiller drives. For higher-power hydraulic or linear actuators suitable for larger vessels, the ACU-200 or ACU-400 models are required.

Is this autopilot suitable for offshore navigation?

Yes, the Raymarine Evolution Tiller Pilot autopilot is designed to provide precise heading assistance, making it suitable for both coastal and offshore navigation.

What are the mounting requirements for the EV-1 sensor to ensure proper operation?

To ensure the accuracy of the EV-1 sensor, it is critical to mount it in a suitable location. It must be installed at a safe distance from any equipment generating magnetic fields or electromagnetic interference (EMC), such as engines, speakers, or power cables. Respecting these distances ensures reliable heading data.
