Your Race in Numbers
Now that you've defined your race in ChartedSails, you can extract valuable insights from the data. This section will show you how to navigate through your race data and understand the key metrics that can help you improve.
Navigating Through the Race
To begin analyzing your race data:
- Click on the orange bar on the timeline that represents your race
- ChartedSails will zoom in on the race and filter out any other data
- All the numbers and metrics will now be exclusive to the race you're analyzing
Analyzing the Start
The race start is critical - often determining your position for the entire race. Click on the starting sequence and select the Performance tool to access these key metrics:
Key Start Metrics:
- Speed at the gun - The faster the better. Too slow may indicate you were stuck beneath another boat or being overly cautious
- Time and distance to line - Should be as close to 0 as possible without crossing early
- Speed at the line - Should match your target speed for the conditions
Beyond the Numbers:
- Did you start on the favored end of the line?
- Had you correctly identified the favored side of the course?
- Did your start strategy work as planned?
Action Step: Add a comment on the timeline about your start. Was it good? If not, what specific problem occurred? Identifying areas to improve is the first step toward progress.
Leg-by-Leg Analysis
Click on each leg on the timeline to focus on that specific portion of the race:
For each leg, ChartedSails shows:
- Distance sailed
- Average speed
- Maximum speed
- VMG to the next mark
Questions to Ask:
- What side of the course did you sail on, and why?
- Did the wind rotate during the leg? Did you spot and react to shifts?
- How many maneuvers did you execute? (Generally, fewer is better, but not at the expense of missing shifts)
- Did you pinch because you tacked too early?
- Did you overstay a mark and waste distance?
- Are your speed, wind angle, and heel angle on target?
When you have multiple boats in your group, the leg-by-leg analysis becomes even more powerful. Compare your VMG, SOG, and TWA against the boats that beat you. Were you sailing a tighter angle but going slower? Or footing for speed but losing on VMG? These side-by-side comparisons pinpoint exactly where you gained or lost time.
Overall Race Performance
After analyzing individual components, review your overall race performance:
- What was your average speed for the entire race?
- How does your total distance sailed compare to other boats in your group?
- How do your upwind and downwind VMG compare across the fleet?
Session Reports
For a complete overview of your racing day, use the Session Report. Click the report button next to the session title to generate an easy-to-read summary of all the races in one day.
The session report includes:
- A weather overview for the day
- Average upwind and downwind performance for all boats across all races (excluding non-racing time, so you get a true picture of racing performance)
- Race-by-race breakdowns with a start lineup image showing all boats at the line, and a table comparing angles, VMG, SOG, distance, and time leg by leg for every boat
Session reports are a great way to quickly see the big picture and share results with your group.
Pro Tip
