Nauti-Control ST & N2K Wireless vs Raymarine S100: Smarter Control at a Fraction of the Price

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.
