Hi Everyone,
We're VesselSense, a new marine systems integration company based in San Diego, California. We build onboard computer systems on Raspberry Pi, design and build custom wireless sensors, and connect existing marine electronics into a unified platform. Everything we build runs on open-source software — the same ecosystem this community is built around.
What We Do
Many boat owners encounter what's possible with this software — real monitoring, proper integration, full visibility into their systems — and want it on their vessel. The barrier is almost never the hardware cost or the software itself; it's the setup, configuration, and integration work. That's the gap we fill: professional installation and configuration using the same tools this community builds with, without proprietary lock-in and without replacing equipment that already works.
Onboard computer systems. We build Raspberry Pi-based marine computers with marine interface boards, housed in waterproof enclosures. The software stack is configured and bench-tested before delivery, matched to each vessel's equipment. Navigation and instrument-focused builds use OpenPlotter. Vessels with Victron electrical systems use VenusOS Large on Raspberry Pi, which integrates the full Victron system alongside the vessel's instruments and sensors. Larger setups often run both on separate hardware. The system arrives configured and working — not a box of parts.
Custom wireless sensors. Where a vessel is missing coverage, we build ESP32-based wireless sensor nodes using SensESP that connect over WiFi and feed data into SignalK alongside the vessel's existing instruments. We've built sensors for engine and mechanical systems, batteries and electrical, tank levels and fluid monitoring, environmental conditions, and bilge and safety systems. The sensors extend what the boat can see — they don't replace existing hardware.
Monitoring and visibility. Once the system is running, owners have full visibility into their boat from any phone or tablet. Dashboards, alerts when something needs attention, and continuous historical logging so they can spot developing problems before they become failures: a bilge pump cycling more frequently, a battery that isn't holding charge the way it used to. We can also connect an AI assistant — Claude, ChatGPT, or others — directly to the boat's data, so owners can ask "How are my batteries?" and get a real answer instead of staring at raw numbers.
On-site installations in San Diego; remote configuration and ship-to-location for everyone else.
