The idea · Future SmartSail concept

HelmLink.
The home of your onboard captain.

Where Pathr Co-Captain leaves the phone and lives on the boat itself.

HelmLink is a future SmartSail concept. A small piece of hardware that does two jobs at once. It speaks to the boat's existing autopilot and instruments so Pathr can drive them directly, no retyping. And it hosts the Co-Captain locally, so the AI advisor that knows your vessel, your routes, and the conditions keeps working even when the boat is offline.

Pathr Navigation ships first. Pathr Co-Captain comes next. HelmLink is where the whole stack comes home, on the boat.

Small. Hidden. Quiet.
The idea
One app. One route. One system that actually works together.
The problem

Modern apps. Legacy helms. AI on the wrong side.

Boaters today juggle two worlds. The app world is fast, modern, free of headaches. The helm world is chartplotters, autopilots, and instruments that were designed before the iPhone. Getting from one to the other still means typing waypoints by hand.

And the smart part lives in the wrong place. Modern marine AI runs on the phone, where signal disappears the moment you leave the harbor. The advisor that should know your boat best is the one that goes quiet first.

Manual re-entry

Boaters plan a route in a modern app, then re-type every waypoint into a chartplotter from 2008.

Closed ecosystems

Each marine electronics vendor wants the boater locked into their stack. Cross-vendor integration is rare and expensive.

Forced upgrades

To get "modern" plotting, owners are told to replace working hardware. That's a wall of cost, not a path forward.

Software/hardware gap

Modern routing software sits on a phone. The autopilot sits at the helm. Nothing connects them cleanly.

The AI lives ashore

Marine AI advisors run on the phone. The moment cell signal drops, the advisor goes quiet. Exactly when the boater needs it most.

How it would work

Two jobs. One small box on the boat.

HelmLink lives quietly on the boat. A small piece of hardware that speaks to the existing NMEA network so Pathr can drive the autopilot directly. And the local home for Pathr Co-Captain, so the advisor that knows your boat keeps working when cell signal doesn’t.

01

The app plans it

Pathr generates the route. Depth-aware, hazard-aware, weather-aware. Same routing brain that already ships in the app.

02

HelmLink bridges it

A small piece of hardware that speaks to the boat's NMEA network and translates the Pathr route into something the boat's existing autopilot understands.

03

The boat follows it

Waypoints arrive at the autopilot without anyone manually re-entering them. The boater monitors. The boat steers.

04

The Co-Captain rides along

HelmLink hosts the Co-Captain locally. The AI advisor that knows your vessel, your routes, and live conditions keeps working when cell signal drops. Onboard, offline, with you.

Design principles

Built around the boat the owner already has.

Local-first AI

Pathr Co-Captain runs on HelmLink itself. The advisor that knows your vessel and your routes keeps working when cell signal doesn't. Onboard, offline, on every trip.

No new chartplotter

HelmLink rides alongside the gear you already own. No 30-year-old screen to rip out, no $4,000 plotter to buy.

No locked ecosystem

Pathr is the boater's app. HelmLink is the boater's bridge. Both work whether the rest of the helm is Garmin, Raymarine, B&G, or Furuno.

Safe by design

A clean handoff between routing software and the autopilot. The captain stays in command. HelmLink is a bridge, not a replacement.

Where it sits on our roadmap

An honest answer: not yet.

HelmLink is not in the current Pathr Navigation roadmap. It's a future-rounds initiative, something we're researching now because we believe it's where this market eventually goes.

Live
Phase 1 · Today
Pathr Navigation

A modern boating navigation app, live on the App Store today. The product live conversation is about this.

Building
Phase 2 · Next
Pathr Co-Captain

An AI co-pilot built into Pathr. Briefs trips, watches the things you can't, learns your boat.

Concept
Phase 3 · Future
HelmLink

The bridge to the helm, and the home of the onboard Co-Captain. After Pathr and the Co-Captain are real businesses, HelmLink is where the whole stack comes home: on the boat, offline-capable, on every trip.

Why we're talking about it now

Three founders. Three angles on hardware.

LucasFounder
Flight test discipline

National Test Pilot School graduate. Led flight test and validation programs: the discipline of safely qualifying complex hardware systems under real operating conditions.

ChrisCo-founder · Software
Commercial-scale hardware

Built remote-control hardware and cloud systems at commercial scale. Knows what it takes to ship reliable embedded products.

WillCo-founder · Hardware
Concept to commercialization

Award-winning innovative product developer. Has taken hardware from rough concept all the way through commercialization.

We have the team to build it and validate it safely. That's the bar HelmLink has to clear before it ships. For now the company stays heads-down on Pathr Navigation and Pathr Captain. HelmLink waits its turn.

Curious about HelmLink?

We're early. If you're a hardware partner, a marine OEM, or just a boater who'd love to see this exist, let's talk.
