# Real-Time Tracking and Visualization

eStela allows you to follow races live as they happen or watch a full replay once the tracking session has ended. Visualization is one of the most powerful features of the platform, giving both organizers and spectators a clear view of what’s happening on the water.

### Live View and Replay

* When a tracking session is active, positions update in real time.
* Once the session is stopped, the replay becomes permanently available. Replays remain accessible even if your account is later downgraded to the Free plan.

### Sharing the Tracking Session

Each tracking session has a unique URL for visualization. You can copy and share this link with:

* Participants
* Spectators
* Media teams

Most organizers share the link via social media, WhatsApp, or email before or during the race.

The visualization page works on all major browsers. If you encounter any issues viewing a session, please contact support.

### Visualization Features

While watching a session (live or replay), viewers can access:

* Real-time classification
* Laylines and wind overlays
* Start time countdown
* Boat distances

These tools provide clear insight into race dynamics and help keep spectators engaged.

### What Can Be Configured

As an organizer, you can customize several elements of the tracking session, including:

* Session name
* Course setup
* Wind data
* Starting and ending time
* Layline angle
* Three hull lengths zone
* Show/hide country flags

You can also:

* Delete a boat’s track if it was mistakenly included
