SailWatcher – Sail Analysis

Take a picture of the sail and let SailWatcher calculate key parameters like camber, draft, chord, twist, entry and exit angles.

SailWatcher is the perfect app for all sailing and boating lovers. Whether you are an expert or a beginner enthusiast, this app will help you plan, monitor and live your adventures at sea to the fullest.

Key features:

• Track course and key points: While sailing, SailWatcher records the boat's GPS position and that of the points where the shots were taken to retrieve parameters
• Practical 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's shape lines, returning draft, camber, twist, entry and exit angle.

Thanks to an intuitive interface and advanced features, SailWatcher allows you to focus on what you love most: sailing.
The app is designed to offer you all the information you need, right in the palm of your hand.

FREQUENTLY ASKED QUESTIONS

• Which 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 moment the photo is taken.

• Does it work on every sail?
  SailWatcher calculates the parameters of all sails with highlighted shape lines. If your sails have visible shape lines, you can use SailWatcher.

• Is an internet connection required?
  SailWatcher is designed to be used on the open sea; it does not require an internet connection, except for some secondary functions (e.g. sharing).

• Can I share the obtained data?
  Yes, via a unique URL. The web page will contain the photo, the shape lines with their parameters, additional data (wind speed, ...) and additional notes entered by the user.

• Why can't I retrieve the data?
  SailWatcher performs a series of calculations to identify shape lines. If you can't retrieve the data for your sail, let us know by email. We will analyze the case and improve the algorithm so that it also identifies your sail.
