Question 1

How does Vantage calculate the wind direction?

Accepted Answer

What makes Vantage truly unique is the accuracy of our wind algorithms. In contrast to most other sailing analytics tools, Vantage does not just use a fixed wind direction for an activity, but uses a revolutionary approach to adjust for even the smallest shifts. The approach relies on polars generated using machine learning, and efficient computation that uses the polar as a guide to understand what's a shift, and what's pressure.

Question 2

Does it matter which boat class I upload to?

Accepted Answer

Yes! Make sure to always use the right boat class for the session you are uploading. Some classes, including all Olympic classes and a few others, have pre-defined class polars that affect the way the wind detection functions. If you have made an error here, you can always switch the selected boat from the activity settings!

Question 3

My analysis looks off, what should I do?

Accepted Answer

If it looks significantly off, it is very likely to be caused by an error in the wind detection. For example, if the algorithm fails to identify a good general wind direction as a starting point, the rest of the analysis will struggle to catch up. Thus, my main recommendation here is to always check the True Wind as shown on the activity page. If it is off, simply click on it and choose a general wind direction that matches your activity. Additionally, check for whether you have towing included in your session or motorized segments. This should always be excluded for the analysis to work appropriately.

Question 4

I can't see my connections for data comparison, what should I do?

Accepted Answer

If you are connected, and have sailed at the same time and location, Vantage will automatically identify the matching activities and allow you to compare data. However, sometimes, you may experience not being able to see your connections under data comparison. Most of the time, this is caused by an issue in the device timestamps (wrong time zone) in one of the activities. To fix this, make sure to double check the activity start and end time under Activity Settings → Offset Activity Time. Here, you can easily adjust the start and end time.

Question 5

I uploaded a video, but I can't see any telemetry

Accepted Answer

This is generally caused by a time zone issue on either the instrument's timestamps, or the video timestamp, which causes the telemetry to not match up with the video time. To fix this, assess whether your activity time or video time is wrong. An easy way to do this is through the video synchronization page (upper right on the video player). Here, you can shift the video time by hours in each direction, until you can see it match up with the instrument telemetry.

Question 6

My activity failed to upload

Accepted Answer

Firstly, check that your device meets the requirements listed on the device setup page. If it still fails, send us an email at info@vantage-sailing.com with the file attached. Then, we will review the data and get back to you once the issue is fixed. If you have a capable sailing instrument / GPS that is not supported yet, also feel free to send us an email!
