Introducing...

A Plug-and-Play Marine Navigation System — Radically Affordable.

AIS, GPS, and NMEA 2000 support in one integrated unit, powered by open-source software and purpose-built for sailors who’d rather be sailing than debugging tech.


⚓ Everything You Need—Nothing You Don’t

🛰️ AIS & GPS Compatible

View real-time position, speed, and heading from connected GPS, and monitor nearby vessels when an external AIS is added—no need for expensive displays.

🔌 NMEA 2000 + 0183 Support

Connect your boat’s existing sensors and instruments — PropheSea speaks both languages right out of the box.

🖥️ Open-Source & Customizable

Built on OpenPlotter, Signal K, and OpenCPN—fully transparent, community-driven, and endlessly tweakable.


And That’s Just the Beginning…

🧭 Plug-and-play

Plug-and-play navigation: connect your existing AIS and GPS sources via NMEA 2000, 0183, or USB—no extra displays or modules needed.

🌐 Wi-Fi Enabled

Stream instrument data to tablets, phones, or laptops — no extra apps or hardware required.

🛠️ Easy to Install

Mount it, power it, connect it. No command line. No headaches. Just cruise.

  • Wi-Fi for updates, syncing, and streaming

  • Works with NMEA 2000 and 0183 right out of the box

⛵ Built for Sailors, by a Sailor

Phoenician Systems was founded by a lifelong sailor and DIY tinkerer who wanted a better marine nav system — one that actually made sense and didn’t wreck the cruising budget.
What started as a personal project is now ready for the world.
