A senior pilot doesn't hand you a chart and walk away. They tell you what's ahead. What to watch for. What your specific boat can and can't do. That's LIR.
| Question a captain actually asks | Chart apps | LIR |
|---|---|---|
| "My Cat 3406 is running hot — what should I check?" | — | Real engineering answer from 25 engine manuals |
| "Is it safe to leave for Charleston tomorrow with my 4.5 ft draft?" | — | Vessel-specific passage analysis with weather, tides, and active LNM notices |
| "What lights do I display anchored in a designated anchorage?" | — | Pulled from the actual CFR — Rule and text cited |
| "What's the current at Hell Gate this afternoon?" | — | Live NOAA CO-OPS prediction for your exact departure time |
An AI crewmate with the working knowledge of a Master Mariner. Type a question — engineering, regulations, navigation, passage planning — and get a real answer from real sources.
Enter where you're going from and to. LIR comes back with a senior pilot's briefing — what's ahead, weather along the corridor, active USCG notices matched to your route, tidal windows for bridges, and fuel analysis for your specific vessel.
Drop a pin anywhere on US waters. LIR returns a full situational picture — weather, tides, hazards, anchorages, restricted areas, nearby bridges and locks, live vessel traffic.
Most maritime software is built by software people who hired a consultant to "make sure it's accurate."
LIR is different. It was built by Captain Jonathon Snedeker — a USCG Licensed Master in three modes: Oceans, Towing, and Western Rivers. Active commercial captain. He built LIR because the planning tools he needed in the wheelhouse didn't exist.
The result is a tool built on real commercial experience — by a captain who has worked every waterway it covers.
"Our silicon is salty — not built in a valley."

Not yet. LIR today is an AI crewmate that answers questions, briefs passages, and gives you situational awareness anywhere on US waters. The chart view and full navigation features are on the roadmap.
LIR isn't a nav app. It's something nav apps don't do — a real AI assistant trained on actual maritime knowledge with a captain's judgment. The price reflects what it actually replaces (asking a senior pilot a question), not what charts cost.
