The SailScan mobile app uses computer vision to analyze the draft stripes on a mainsail or jib and returns camber, draft, entry, exit and twist data for every stripe.
AMSTERDAM, Nov. 15, 2026 /PRNewswire-PRWeb/ -- SailScan, the sail shape measurement app, will be at METSTRADE in Amsterdam from 17 to 19 November, meeting maritime industry representatives including boat-makers, sailmakers, coaches, class associations, and race teams.
SailScan measures sail shape from a photo taken on a mobile iOS or Android device. A sailor photographs the mainsail or jib, and SailScan finds each draft stripe, traces it from luff to leech and returns five numbers for every stripe: camber, draft position, entry angle, exit angle and twist. The traced stripes are appended to the photo, so the sailor can see exactly what was measured and correct any line before saving. Maintaining and saving proper sail shape can help increase speed on the water and reduce race times. "Racing by Numbers" is the company's mantra.
The measurements come from SailScan's own computer vision model, built in house and trained on thousands of photos of real racing sails. SailScan also makes AI powered suggestions on how to refine your trim and your aerodynamic package, based on the shape it measures. Sailors can correct and save a traced stripe in the app for later review. Scans are saved with notes and can be compared side by side: tack to tack, sail to sail, or one rig setting against another. The SailScan app works on mainsails and jibs on everything from RC boats and one-design dinghies to grand prix race boats and superyachts. SailScan is built and maintained in San Francisco, CA by Seamaphore.
"Good trimmers spend years building an eye for sail shape," said Alex Higby, founder of SailScan. "But an eye can't tell 10 percent camber from 11, and it can't remember what the sail looked like three races ago. SailScan puts numbers behind that eye, so a team can find a fast setup and get back to it."
SailScan is a training and debrief tool. Sailors should check their class rules before using it while racing.
SailScan is available on the App Store and Google Play, and is free to use for now.
