If you’re considering a wireless control option for your Raymarine autopilot, you might have looked at the Raymarine S100 remote. While it’s a well-known option, the Nauti-Control ST Wireless and N2K Wireless modules offer far more functionality — and usually at less than a quarter of the cost.
Why Choose Nauti-Control Over the Raymarine S100?
The difference comes down to capability and connectivity.
The Raymarine S100 is a simple remote. It allows you to adjust course and control basic autopilot functions, but that’s where it ends.
The Nauti-Control Wireless modules, on the other hand, give you:
- Full control from mobile and watch apps (Nauti-Mobile and Nauti-Wear)
- A built-in web server for configuration and status monitoring
- Wi-Fi connectivity for integration with apps such as OpenCPN, Navionics, and Signal K
- Compatibility with both modern and legacy Raymarine autopilots via SeaTalk / SeaTalk NG / NMEA 2000 networks
It’s a complete bridge between your boat’s data bus and your personal devices — something the S100 simply isn’t designed to do.
Compatibility Made Simple
- ST Wireless connects directly to SeaTalk 1, making it ideal for older pilots such as the ST4000, ST6000, or ST7000 series.
- N2K Wireless connects to NMEA 2000 or SeaTalk NG backbones, perfect for newer Evolution autopilots like the EV-100, EV-200, and EV-400.
- Mixed network? Add a standard SeaTalk 1 ↔ SeaTalk NG converter and you’re ready to go.

Real-World Value
At roughly four times the cost of a Nauti-Control module, the S100 provides a basic text display and button interface, but no data sharing, no app support, and no network connectivity.
With Nauti-Control, your smartphone or smartwatch becomes the display, showing live heading, wind, depth, speed, and more from your boat’s data bus. You can steer, switch modes, or follow a track — all with a tap on your phone or wrist.
Supported Commands
Both ST Wireless and N2K Wireless support the full set of autopilot commands:
- ±1 / ±10 heading adjustments
- Auto / Standby / Track / Wind modes
- Feedback and live data directly from your autopilot bus
This makes Nauti-Control a true functional replacement for obsolete control heads such as the ST7000, while also providing a flexible modern interface.
