Sail Scan
AI Powered Sail Shape Analyzer
About
This app uses your phone's camera to analyze sail shape by reading trim stripes. It provides detailed measurements like camber depth, draft position, and twist, helping sailors make real-time adjustments to improve speed and performance. Save your scans, build a library, and connect rig settings to your progress on the water.

October 6, 2026
• A new home screen: pick Main or Jib, then open the camera or choose a photo. • Sign in with Face ID or Touch ID (passkeys) instead of typing your password. • Share your measurements as a CSV spreadsheet, or as a Njord photo package with timestamped overlay images and optional notes. Main and jib readings stay separate. • Photos and stripe lines stay aligned on rotated scans, and saved scans keep the matching photo and measurements. • Automatic crash reporting so we can fix problems faster. • Fixes and stability improvements.
MoreFAQ
What sail types does Sail Scan work with?
Sail Scan is designed to work with both mainsails and jibs. It supports a wide range of boats, from small one-design classes to grand prix racers and superyachts.
How does Sail Scan measure sail shape?
Sail Scan utilizes computer vision to read the trim stripes on your sail. By analyzing these stripes, it quantifies metrics like camber depth, draft position, and twist, which are difficult to assess visually.
Can I save and compare my sail scans with Sail Scan?
Yes, Sail Scan allows you to save your scans and build a library of your sail shapes. You can then compare scans across different points in time or tack to track the impact of your rig settings.
What are the key measurements provided by Sail Scan?
Sail Scan provides detailed measurements including camber depth (how much shape you're carrying), draft position (where the depth sits front to back), and twist (how the top opens relative to the boom).
Is Sail Scan suitable for beginners?
Sail Scan is built by experienced sailors and provides the data behind expert trimming. This allows sailors of all levels to understand and replicate fast settings, accelerating their learning curve.
What devices is Sail Scan compatible with?
Sail Scan is available for iPhone, iPad, and iPod devices. It requires iOS 4+ and is optimized for these Apple platforms.
