Sailing With Your Group

Your own sailing data is valuable. Your data alongside the boats you race and train with is transformative. When you can see your track next to the boat that beat you to the windward mark, you start to understand why — and that's where real improvement begins.

Groups in ChartedSails make this easy. Once you're in a group, your data comes together automatically so you can replay races with all the boats, compare performance, and learn from each other.

Creating a Group

You can create a group from the web or the mobile app.

On the web: Go to your Groups page and click "Create Group." Give it a name — your fleet, your sailing club, your training crew — and you're in.

On mobile: Open the Groups tab and tap "Create Group."

Inviting Other Sailors

Once your group exists, you'll have a six-letter invite code. Share this code with the sailors you want in the group — via text, email, WhatsApp, or on the whiteboard at your club.

To join, they go to the Groups page (on web or mobile), tap "Join Group," and enter the code. That's it.

How Sessions Work in a Group

Once everyone is in the same group, getting your data together is mostly automatic.

The best approach: schedule a session in advance. Before your sailing day, create a session in the group (e.g., "Saturday Training"). When group members upload their data from that day, it will automatically be added to the session. No extra steps needed.

If you didn't schedule ahead, any group member can assign their session to the group after uploading. On mobile, open the session and tap the group button to assign it. On the web, click the share button and assign it to the group. Once one person has done this, other group members' uploads for the same time period will join automatically.

Missing someone's data? ChartedSails will show you if a group member has uploaded data for the same time period but hasn't added it to the session yet. You can pull their data in with one click.

What You Get

With everyone's data in the same session, you can:

• Replay the race with all boats visible — watch the whole fleet from above
• Compare tracks to see different lines and strategies
• Analyze performance side by side: who had better VMG upwind, who sailed a shorter distance, who lost time on maneuvers
• Generate session reports with leg-by-leg breakdowns for all boats

The more boats in your group, the more you'll learn from every session.

Pro Tip

Encourage everyone in your group to record every session, even casual practice days. The habit of consistent recording pays off when you have weeks and months of data to compare trends and measure improvement.

Now that you have your group set up, let's move on to preparing your sailing data for analysis.
