NMEA 2000
RPM, fuel flow, pressure, temperature, voltage, tanks, depth, heading, wind, position, speed, and available alarms.
THE BOAT GRAPH
Not more gauges.
More context.
Salinity is designed as the boat’s private operating memory. It connects what the network measured, what the boat was doing, where it happened, what changed first, and what the owner did next.
PRIVATE BOAT MEMORYOne boat.
One history.
One history.
Owner-controlled, offline-first, and read-only on the NMEA network.
Trips
Time and place turn isolated readings into operating context: idle, reverse, speed, load, sea state, and what changed first.
Conditions
NOAA tides, weather, route context, and owner limits sit beside the boat record without pretending to be the helm.
Records
Maintenance, incidents, licenses, registrations, permits, photos, receipts, and notes become part of the same working history.
CONNECTED SYSTEMS
What that memory
can become.
Availability is stated on every system. “Roadmap” means product direction—not a feature you can rely on today.
Graph
One private map of the boat, engines, sensors, trips, maintenance, places, files, people, and the relationships between them.
Modes
Keeps neutral idle, reverse, forward speed groups, and changing load separate so the right operating state is compared with itself.
Memory
Preserves the lead-up, exact moment, and recovery around an irregularity instead of keeping only the final alarm.
Proof
Connects service dates, engine hours, part numbers, receipts, photos, and post-service trips into a defensible maintenance history.
Guardian
Owner-approved remote awareness for anchor, depth, tide margin, electrical, engine, and connection changes—with clear delivery limits.
Forecast
Compares the planned trip with the boat’s own fuel history, range reserve, conditions, tides, crew, and service readiness.
Network
Explains which NMEA devices and data channels are present, missing, duplicated, stale, or assigned to the wrong engine.
Fishing
Places catches, conditions, tide stage, depth, season, method, and private marks together without exposing the owner’s spots.
Passport
Builds an owner-controlled vessel history from trips, service, equipment, documents, and verified evidence for a future sale or survey.
01Record

04Share
Let the owner choose who sees it.
OPEN DIRECTION
More ways to listen.
Never a way to steer.
Today’s supported path is a compatible NMEA 2000-to-WiFi gateway. Signal K and NMEA OneNet interoperability belong on the roadmap where they can widen the available context without changing Salinity’s read-only boundary.
Salinity records, organizes, compares, and explains. It does not autonomously navigate, operate machinery, diagnose a failure, or certify that a boat is safe.
