Monitor and Optimize Your Sails
Take a photo of the sail with your smartphone and let SailWatcher calculate the fundamental parameters such as camber, draft, cord, twist, entry angle, and exit angle. Join the beta on iOS now.
Harness the Potential of Your Sails.
Track the parameters of your sails directly in the application and monitor changes over time. SailWatcher provides a simple way to maintain an accurate record of your sail settings, allowing you to optimize your boat's performance.
Track the Route and Key Points
During navigation, SailWatcher records the GPS position of the boat and the points where shots were taken to retrieve the parameters.
Convenient and Fast
To perform the analysis, simply take a shot, select the areas of interest, and finally the LUFF.
Share
Once the parameters are calculated, you can share all the information, including the photo and personal notes, by generating a unique URL.
SailWatcher Engine
An algorithm has been developed that, requiring only a few pieces of information from the user, identifies and evaluates the sail shape lines, returning draft, camber, twist, entry, and exit angles.
Frequently Asked Questions
If you have other questions about SailWatcher contact us at hello@sailwatcher.com
What parameters does it calculate?
SailWatcher calculates the following parameters: camber, draft, twist angle, entry angle, exit angle. It also saves the boat's speed at the time of taking the photo.
Which devices is it compatible with?
SailWatcher is compatible with Apple iPhone 8 and later. There is no plan for an Android version. A version for iPad is also planned.
Does it work on every sail?
SailWatcher calculates the parameters of all sails with highlighted shape lines. If your sails have highlighted shape lines, you can use SailWatcher.
Does it require an internet connection?
SailWatcher is designed to be used in open water, it does not require an internet connection, except for some secondary functions (e.g., sharing).
Can I share the obtained data?
Yes, through a unique URL. The web page will contain photos, shape lines with their parameters, additional data (wind speed, ...) and additional notes entered by the user. Here is an example.
The tool cannot retrieve the data
SailWatcher performs a series of calculations to identify shape lines. If you cannot retrieve the data from your sail, let us know. We will analyze the case and improve the algorithm to identify your sail as well.
No Cost
SailWatcher is free, no payment, subscription, or purchase of additional equipment is required.
All you need, in addition to a suitable sail, is a smartphone.
The SailWatcher Project
SailWatcher originated as a project within the ISISLab laboratory at the University of Salerno.
