Maretron RAA100 Rudder Angle Adapter – RAA100-01

Improve your helm awareness and steering diagnostics with the Maretron RAA100 Rudder Angle Adapter (RAA100-01) — a precision interface that converts analog rudder angle signals into digital data for your vessel’s NMEA 2000® network. Designed for compatibility with a wide range of rudder angle sensors and rudder reference systems, the RAA100 enables real-time rudder position monitoring on NMEA 2000® displays, chartplotters, multifunction displays (MFDs), and vessel monitoring software like N2KView®.

By translating traditional analog rudder feedback into a standardized NMEA 2000® data format, the RAA100 allows you to integrate rudder angle information alongside navigation, engine, and environmental data — giving you greater visibility of vessel behavior and better situational awareness underway. Whether you’re tuning autopilot performance, monitoring steering alignment, or simply keeping an eye on boat handling, this adapter provides the accurate, network-ready rudder data you need.

Built with a rugged, marine-rated enclosure and sealed network connectors, the RAA100-01 is engineered for reliable performance in harsh offshore environments. It’s an essential component for modern vessel monitoring and control systems seeking to fully leverage rudder position feedback.


Technical Specifications

  • Brand: Maretron

  • Model: Rudder Angle Adapter

  • Part Number: RAA100-01

  • Network Interface: NMEA 2000® (IEC 61162-3)

  • Input Type: Analog rudder angle sensor signal

  • Output: NMEA 2000® rudder angle PGNs (e.g., 127245 Rudder)

  • Connectors: Sealed NMEA 2000® male/female connectors

  • Power: Powered from the NMEA 2000® network

  • Environmental Rating: Marine rated for moisture and corrosion resistance

  • Installation: Inline with NMEA 2000® backbone and compatible sensor wiring


Key Performance Features

  • NMEA 2000 Conversion: It converts the analog resistance signal from your existing rudder sender into digital PGNs that can be read by chartplotters, high-resolution instruments, and autopilots.

  • Calibration Support: The RAA100 supports multi-point calibration, allowing you to account for non-linearities in your steering linkage. This ensures the "0 degree" center point and maximum "hard over" angles are displayed accurately.

  • Works with Existing Senders: It is designed to work with standard American (240-33 Ohm) and European (10-180 Ohm) resistive senders, meaning you likely won't need to replace your current rudder hardware.

  • Smart Filtering: Includes advanced digital filtering to provide a stable, jitter-free reading on your screen, even if the rudder is vibrating or moving rapidly in rough seas.

  • Plug-and-Play Power: The module is powered directly by the NMEA 2000 bus, drawing very little current, which simplifies the wiring process in the lazarette or engine room.

In the Box

  • RAA100 Adapter Module: The main interface hardware with a Micro-C NMEA 2000 connector.

  • Mounting Hardware: Stainless steel screws for secure installation.

  • User Manual: Includes resistance tables and calibration instructions.

  • Note: The actual rudder sender (sensor) and mechanical linkage are not included and must already be installed on the boat.


Applications

  • Rudder angle display on chartplotters and helm displays

  • Autopilot integration and performance feedback

  • Steering system diagnostics and alignment tracking

  • Vessel control systems and monitoring dashboards

  • Cruising, racing, and navigation awareness enhancements


Summary for the User

The RAA100 is an essential upgrade for owners of older vessels who want to bring their steering diagnostics into the digital age. It eliminates the need for dedicated analog rudder gauges at the helm, saving dash space and providing a much more accurate reading than a needle on a dial.

Installation Tip: If your boat has dual steering stations, you can often use a single RAA100 to monitor the sender and broadcast the data to displays at both the flybridge and the lower helm simultaneously.
