Return to Sea: Building My Own Digital Bridge

How a Raspberry Pi, open-source software, and a little pirate ingenuity could change the way I live aboard.

There is something rather dangerous about giving a retired IT guy with a passion for electronics, a love of the sea, and an overactive imagination access to YouTube.

One minute, I’m watching a video about somebody else’s boat. The next, I’m mentally tearing apart the electrical system of a boat I haven’t even purchased yet.

That’s exactly what happened when I discovered a video from Sailing Exodus, demonstrating a custom Raspberry Pi marine dashboard that brings navigation, batteries, weather, solar and onboard equipment together.

OpenPlotter and Signal K

OpenPlotter provides an open-source marine computing environment, while Signal K makes information from compatible instruments, including NMEA 2000 networks, accessible to custom applications. Instead of accepting a manufacturer’s dashboard layout, I could design one around the information I actually need.

StormyOS: Return to Sea Edition

I’ve already been building StormyOS as part of Stormy Sailors Maker Lab, bringing Linux, Raspberry Pi computers, servers, sensors and custom dashboards together. Why not take that experience aboard my future motor yacht?

My digital bridge could display GPS position, heading, depth, weather, battery charge, solar output, shore power, engine hours, maintenance reminders, bilge alerts and freshwater levels—where the boat’s instruments and sensors support them.

Ember Takes the Watch

Ember, our mischievous fox, could become the ship’s digital watchkeeper, presenting status summaries and relaying alerts. If a battery drops low or a bilge sensor detects water, she’d certainly have something to say. But safety-critical alarms must remain independent of any AI assistant.

A Captain’s Log That Almost Writes Itself

StormyOS could automatically prepare daily entries using position, weather, engine hours and other available data. I’d add the photographs, observations and stories, then review selected entries for the public Return to Sea journal. Private operational records and live location would stay private.

Build It Before Buying the Boat

The best part is that I can begin in Edmonton. With simulated GPS, engines, batteries and tanks, I can build and test the dashboard before purchasing a vessel. Once I find the right boat, we’ll adapt it to her actual equipment.

Safety Before Cleverness

A homemade computer isn’t a substitute for dedicated navigation gear, independent bilge alarms or properly protected electrical systems. StormyOS would begin as a read-only companion, not a replacement for the equipment that keeps a boat safe.

More Than an Electronics Project

Return to Sea isn’t just about buying a boat. It’s about bringing together my Royal Canadian Navy background, years in IT, love of open-source engineering, and the freedom to create a new life on Canada’s west coast.

The first step is a virtual vessel. The next is a custom bridge. And eventually, Ember gets a new posting.

The sea is calling. The electronics are waiting. And apparently even my future boat is going to need a server room.

Think Like A Captain. Play Like a Pirate.
