It starts with one chart and one routing engine, live on boaters’ phones today. The same stack is now going into the fleet office and aboard the boat.
From the founder
I’ve been sailing since I was a kid. I’ve also spent my career as a flight test engineer on safety-critical autonomous systems. I live in both worlds, and the gap between them is striking: aviation has world-class mobile tools for planning, weather, and automation; marine navigation is still stuck on outdated chart plotters, disconnected apps, and manual workflows. There’s no technical reason for that gap. I’m testing Pathr on my own Catalina 38. The same systems-engineering discipline I learned qualifying autonomous aircraft is how we’re closing it.
“SmartSail Giving Boaters Aviation-level Navigation Tools”Read the articleThe thesis
The chartplotter ran the helm for thirty years, and the apps that followed are chart-shaped: useful, fragmented, interchangeable. The real work still lives in browser tabs, spreadsheets and the captain’s head.
Pathr’s bet is the integrated workflow, built on one chart and one routing engine and shipped one seat at a time.
The strategy
We are not building four companies. We built one stack, and we take it to one seat at a time. Each step reuses what is already built and adds only what it needs.
04 · The intelligence on top
Will reason across all three seats: the chart, the routes, the traffic, the weather and the boat.
01 · The boater’s phone
Routes planned for your boat, and charts that work with no signal.
02 · The operator’s office
Every boat in a rental, charter, club or school fleet on one chart.
03 · The boat
A small hardware bridge to the boat’s own NMEA 2000 network. Steering in testing.

The Pathr stack · Built once
Under every seat
The chart and data backbone
Official NOAA chart data in Pathr’s own chart, usable with no signal.
The routing engine
Depth-aware routes, planned around each boat’s draft.
Live AIS and weather
Traffic, wind, waves and radar on the same chart.
The vessel profile
Each boat’s draft and beam, and through HelmLink, its own instruments.
Why it matters: Pathr owns its chart and its routing engine, so each new seat starts most of the way built.

LivePathr Navigation is free on iPhone and Android: the chart, your position and the anchor alarm. Premium, free for two months for new users, adds automatic route planning, radar, AIS, trip history and more.

Sea Spirit
From the Pathr app: an active route, live AIS and the boat it was planned for
Depth-aware routingPremium
Planned around your boat’s draft. Plan it with a connection, follow it with none.
Official NOAA chart data
Soundings, contours and buoys, on charts that work offline.
Live AIS trafficPremium
The ships around you with name, speed and heading, plus collision details.
Anchor watch
Set a radius when you anchor. If the anchor drags, Pathr sounds an alarm.
Marine weatherPremium radar
Wind, waves and radar on the chart, and a forecast for the week ahead.
Your boat, your trips
The active boat is used for every route you plan. Every trip is recorded, and Premium lets you look back at all of them.
Try it yourself
The operator’s office, Pathr Fleet
Pilot programFleet operations software for boat rental and charter operators, boat clubs and sailing schools: where every boat is, who is running late and what needs attention, read from each boat’s own instruments by a HelmLink on board.
Why fleets come second
The 60-day Pathr Fleet Pilot
Pricing on a call
Open to a small number of rental and charter operators. Units in the field upload their readings over Wi-Fi today, and every unit will ship with a cellular modem, pilot units included. Booking software integrations are planned.
The intelligence on top, Co-Captain
In developmentCo-Captain is the AI co-pilot we’re building on top of the stack. It will reason on the data Pathr already runs: the chart, the routing engine, AIS traffic, the weather and your vessel profile.
Not ChatGPT for boating. Co-pilot, not autopilot. You’re still the captain.
The night before
The forecast read against your boat, your route and your experience.
Underway
Traffic closing from your blind side, wind backing, a shoal near your next turn.
When the plan changes
A different anchorage or an earlier turn, with the tradeoffs spelled out. You decide.
Back at the slip
Engine hours, oil and batteries, with what’s due flagged early.
Pathr Co-CaptainSample
When the plan changes · Saturday, 3:08 PM
“Wind backed southwest earlier than forecast, so your planned anchorage will be a lee shore by 6 PM. I’d move 0.6 nm north into the cove: same depth, sand bottom, good holding. Want me to re-plan the route?”
Illustrative samples. Co-Captain is in development and not available yet.
The flywheel
Public chart data is the same for everyone. What no chart has is how boats are actually used. Every Pathr trip and every fleet boat on a HelmLink adds that, boat by boat, and it is what will make the routing sharper and Co-Captain possible.
01
Boaters log trips in Pathr. In Pathr Fleet, every boat carries a HelmLink.
02
The routes boats really take, the conditions they meet, the hours their engines run.
03
Better routes and alerts, and the context Co-Captain will need.
04
Sharper tools bring more boaters, and more fleets.

Why now
01 · The customer
A weekend trip still runs on a chartplotter, weather sites and four or five apps. The owners buying boats now expect software that works like everything else on their phone.
02 · The AI
Models can now reason over a vessel profile, live traffic, a forecast and a route at the same time.
03 · The data
NOAA charts, depth data, live AIS and satellite weather are now public and cheap to ingest. Turning them into depth-aware routes planned around each boat’s draft is the hard part, and that is the engine we built.
The window
In December 2025 two of the largest peer-to-peer boat rental marketplaces announced a merger, with more than half a billion dollars in bookings between them to date. In June 2026 a growth equity firm made a strategic investment in a major US marina booking platform. Both bets decide who books the slip and who rents the boat.
That second row is the layer Pathr builds.
The team
Safety-critical flight test, geospatial and cloud systems at commercial scale, and product development from concept to commercialization. Based in San Diego, on the water we chart.
