Connected Boat Data
Live dashboards and historical trends drawn from Signal K, NMEA 2000, and the sensors already onboard. Your boat, wherever you happen to be.
OpenSeas Tech Collective builds connected tools for sailors, cruisers, liveaboards, and boat owners — turning marine data into decisions you can actually use.
Three threads run through everything we make — connected data, marine intelligence, and open tools that play nicely with the gear sailors already own.
Live dashboards and historical trends drawn from Signal K, NMEA 2000, and the sensors already onboard. Your boat, wherever you happen to be.
Ownership, value, condition, and decision tools for the boats you have — or the ones you're thinking about. Grounded answers, not generic listings.
Public weather, tides, and crowd-shared marine data — because awareness gets sharper when sailors contribute the same information they rely on.
A growing collective of marine tech projects. All built for sailors who want more signal, less noise.
Connected boat data
Real-time dashboards, trends, and remote awareness from your Signal K network.
Learn moreMarine intelligence
Ownership, value, condition, and decision tools for the boat you have — or the next one.
Learn moreDistributed tide intelligence
Crowdsourced tide and sea-level observations from real boats, docks, and coastal sensors.
Learn moreServices, right in your anchorage
Connects boaters with local service providers — fuel, water, pump-outs, mechanics, groceries, water-taxi. Pin your anchorage, see providers bid in real time, watch them arrive.
Learn moreMost marine software is expensive, clunky, proprietary, or all three. It gets shipped with a chartplotter from 2014 and rarely gets better. The data is trapped onboard. The apps don't talk to each other. The user interface assumes you're wearing dress shoes at a boat show.
OSTC exists to build cleaner, more useful systems for the people who actually live with this stuff — sailors who cross oceans, owners who maintain their own boats, liveaboards who need to know the bilge is dry while they're at the grocery store. The goal isn't to replace seamanship. It's to support better decisions with data that's finally been given room to breathe.
An honest look at what's next. Dates are targets, not promises — boats and weather teach humility.
Scaling the SeaLink beta toward 100 active boats. Hardening the data pipeline, tightening dashboards, and learning from every shakedown.
Begin collecting real-world tide and sea-level observations from SeaLink-connected boats and coastal sensors — building useful shared tide intelligence for remote anchorages and under-charted areas.
Bringing HarbourNow out of prototype into pilot anchorages — boaters requesting services from local providers, bids and ETAs in real time, jobs routing to arrival on the water.
Bringing KeelWise out of development with ownership tools, boat intelligence, and a premium tier for sailors making real decisions about real boats.
Tools that connect — for sailors buying, managing, monitoring, or understanding boats. One collective, many instruments, better seamanship.
