Turn on MapShare
In your Garmin account (https://explore.garmin.com), enable MapShare for your inReach. Your MapShare ID is the short code at the end of your public link.
For sailors · Garmin inReach
Offshore, your loved ones follow the boat live.
A free tracking page for your inReach, built for sailing: your passage track, the wind forecast along your route, and family ashore can message the boat.
Free forever · Nothing to install · Ready in a few minutes
How it works
Three steps, a few minutes.
Create your account
Enter your MapShare ID and email, then send the code we give you from your inReach (or Garmin Messenger) to the MapShare contact. It proves the device is yours — nobody else can claim your boat.
Share one link
Send your link to family, friends or the boat owner before you cast off. They follow the passage live, with no account and nothing to install.
Built for sailing, from departure to landfall
Built by a yacht delivery skipper, for crews and the people waiting ashore.
Messages from ashore
Family and friends write to the boat straight from the tracking page, and it lands on your inReach. You decide whether it’s on or off.
Wind along your route
Animated wind and gusts around the boat, in knots, with a timeline to see what’s coming.
Your full track
Every position kept, colored by speed in knots, with miles sailed in the last 24h and since departure.
Passages archived automatically
After a long stopover, the passage is archived and a new one starts. Rename it, show it on the map or export it to GPX.
Your boat’s name
Show your boat’s name on the tracking page instead of a Garmin code.

FAQ
Where do I find my MapShare ID?
Sign in at https://explore.garmin.com, open the MapShare tab and enable it. Your public link looks like https://share.garmin.com/6RX3P — the ID is the code at the end (here, 6RX3P).
Do I need a Garmin subscription?
Yes — an active inReach plan with MapShare enabled. reChain Tracking reads your public MapShare feed; how often new positions appear depends on your inReach tracking interval.
Does it use my inReach messages?
Following your track doesn’t. The only message you send is the one-off verification code. Messages visitors send you from the tracking page count like any other inReach message on your Garmin plan.
Why do I have to send a code?
It proves you own the device, so nobody else can create an account on your MapShare, change its settings or message you through it.
Who can see my position?
Anyone with your tracking link — just like your Garmin MapShare page. Without an account, we only show the live position and store nothing.
Can I follow a boat without an account?
Yes. Enter its MapShare ID at the top of this page to see its live position. The full track appears if the owner has a free account.
Is it really free?
Yes, there’s no paid plan. reChain Tracking is built by JCskipper, a yacht delivery skipper, alongside reChain, the satellite assistant for Garmin inReach.
Can I track several inReach devices?
Yes. Link as many MapShare IDs as you like to the same account, from your member area.
