Tackr Hub · In development

The SeaTalk WiFi
gateway for Raymarine.

The Tackr Hub is being built to read your Raymarine instruments over SeaTalk1 and stream live wind, boat speed, depth and heading to any phone, tablet or laptop over its own WiFi hotspot. No extra screens, no internet needed.

Protocol Support

SeaTalk1, decoded natively.

Raymarine instruments share data over SeaTalk1, a single-wire bus that carries wind, speed, depth and heading. The Tackr Hub decodes SeaTalk1 itself, so you don’t need a separate converter box or laptop software. SeaTalk1 is running on our prototype Hub now; NMEA 0183 and NMEA 2000 are planned for the production unit.

SeaTalk1

Raymarine Instruments

Isolated SeaTalk1 input. The prototype currently decodes apparent wind speed and angle, boat speed through water, depth and compass heading.

NMEA 0183

Planned

Isolated NMEA 0183 inputs for GPS, wind, depth and other instruments are planned for the production Hub.

NMEA 2000

Planned

An NMEA 2000 connection for modern instrument networks is planned for the production Hub.

How It Works

SeaTalk to WiFi in three steps.

The Tackr Hub sits between your Raymarine instruments and your crew's devices, translating SeaTalk into a live WiFi data stream.

Connect the SeaTalk yellow wire

The Hub connects to the SeaTalk data wire, plus 12V power. Its isolated input handles the SeaTalk signal, so no separate level shifter is needed. Wiring varies from boat to boat, so we’ll confirm the installation for yours.

The Hub decodes and rebroadcasts

Tackr’s own SeaTalk1 decoder turns the raw bus data into wind, boat speed, depth and heading readings, then sends them as JSON messages over WebSocket on the Hub’s own WiFi hotspot, called Tackr-Hub.

Connect and race

Join the Tackr-Hub WiFi network on your phone, tablet or laptop and open the Tackr racing app. Laylines, start line bias and polar performance then run on your real Raymarine data, with no internet connection needed.

Comparison

How Tackr Hub compares.

The usual way to get SeaTalk data onto a phone is a DIY Raymarine-to-WiFi setup on a Raspberry Pi. Here’s how the Tackr Hub is designed to compare.

FAQ

SeaTalk gateway — common questions.

Will the Tackr Hub work with my Raymarine ST40 or ST60 instruments?

The Hub is designed for Raymarine instruments on the SeaTalk1 bus, including the ST40, ST60 and ST60+ ranges and older Autohelm instruments. We’ll confirm compatibility for your specific instruments during beta testing. Newer Raymarine systems such as the i70 use SeaTalkNG, which is based on NMEA 2000. NMEA 2000 support is planned for the production Hub.

What SeaTalk data does the Hub decode?

The prototype Hub currently decodes apparent wind speed, apparent wind angle, boat speed through water, depth and compass heading from SeaTalk1. Its built-in GPS adds position, speed over ground and course over ground. The Tackr app uses these readings to calculate tidal set and drift. More SeaTalk data types will be added during development.

Can other apps use the Hub’s data?

The Hub sends its data as JSON messages over WebSocket, and it’s built first for the Tackr racing app. We’re exploring compatibility with other navigation apps, but none is confirmed yet.

Will the Hub read SeaTalk and NMEA at the same time?

That’s the plan. The production Hub is being designed to read SeaTalk1, NMEA 0183 and NMEA 2000 together and merge them into a single live data stream. Today’s prototype reads SeaTalk1 and GPS.

Do I need to install any software?

No. The Hub runs its own firmware, so there’s nothing to set up on a laptop or Raspberry Pi. It powers up, starts its own WiFi hotspot and begins sending data to the Tackr app.
