The racing chart that thinks like a tactician

Real-time wind, tide, and geometry — all computed on the fly, rendered in milliseconds.

  • Real-time laylines from live wind data
  • Layline corridor safe zone
  • Full-width tide vector overlay
  • Fleet tracking and AIS targets
Screen 02

The start line, mastered

Know exactly which end to favour, how long you have, and when you're OCS — all at a glance.

  • Port and starboard laylines from each pin
  • Live bias calculation in degrees
  • Favoured end detection with glow
  • OCS instant alert with pulse animation
Screen 03

Know your numbers before your competition

Polar performance, VMG optimisation, and race replay — the data that separates good sailors from great ones.

  • Polar performance % against target
  • VMG optimiser
  • Race replay and track review
  • Post-race analysis dashboard

Your instruments are smart.
Your chartplotter is dumb.

Racing sailors are stitching together expensive black boxes, paper charts, and gut instinct. Tackr connects everything into one intelligent system — and puts it on any device you already own.

Hardware

One box. Every instrument on your boat.

The Tackr Hub plugs into your boat's existing instrument network and creates a WiFi hotspot. Open Tackr on your phone, tablet, or laptop — and you're racing.

How it Works

Up and racing
in three steps.

01
Plug the Tackr Hub into your boat's instrument network

A single cable into any SeaTalk1, NMEA 0183, or NMEA 2000 bus. The Hub handles everything — reading, translating, and broadcasting over a unified WebSocket stream.

02
Connect your device to the Tackr WiFi hotspot

The Hub creates its own WiFi network on the boat. Any phone, tablet, or laptop within range can connect — no internet required, no cloud dependency, sub-second latency.

03
Open Tackr and race

Live data streams directly into the Tackr app. Laylines compute from your actual wind. Tide vectors update from your real SOG vs STW. Every number is real, every second.

Safety

Safety built in,
not bolted on.

Depth Alarm

Set a depth threshold. Tackr sounds an alert the moment the sounder drops below it — before you're aground.

MOB Alert

One button drops a man overboard marker on the chart with a bearing and distance — instantly visible to helm.

Anchor Guard

Define an anchor radius. Tackr watches your GPS position and wakes you the moment you start to drag.

Bilge Monitor

Connected to a bilge float switch via NMEA, Tackr alerts you to unexpected water ingress instantly.
