We have prepared a short video covering this topic, or you can skip ahead to the written instructions below.

Setting Up Your Race for Analysis

Before you can analyze your performance, you need to properly define the race in ChartedSails:

Step 1: Highlight the Race on the Timeline

  • Find the approximate beginning of the start sequence
  • Click and hold to make a selection around the entire race

Step 2: Define the Start Line and Time

  • Click the "Create Race" button
  • ChartedSails automatically positions the start line using your GPS data
  • To adjust the line: hover over a mark and drag it to the correct position
  • To adjust the start time: click the time field and use arrow keys for second-by-second precision

Step 3: Define the Race Course

  • Click "Add Mark" to define each leg of the race
  • ChartedSails estimates mark positions from your track, but you can adjust as needed
  • A red track indicates a mark rounding issue - move the mark until the track flows smoothly around it

Common Issues and Solutions

When defining your race course, you might encounter these common challenges:

  • Problem: Red track indicates boat not reaching the mark

  • Solution: Move the mark closer to where your boat actually rounded

  • Problem: Track loops around mark multiple times

  • Solution: Ensure you're placing the mark at the correct location where you actually rounded it

  • Problem: Start line appears at wrong angle

  • Solution: Use the rotation handle to adjust the angle of the start line

Pro Tip

Set aside 15-30 minutes after each race day to define your races in ChartedSails while the details are fresh in your mind.
