Faster By Numbers with SailScan
The stripes behind this page are a sail. Scroll, and watch the camber ease — SailScan reads curves like these on every scan.
In the field
SailScan reads your sail shape in the field and in real time.
Reads any sail from an optimist to a super maxi — Mainsails and headsails — Port or starboard tack. Use your mobile phone to analyze draft stripes for accurate camber, draft, entry, exit and twist data.
How it works — annotated on the stripe
01
Take a photo
Take a photo with your phone and our computer vision model gets to work.

02
Read and measure
SailScan finds each draft stripe and traces the curve from luff to leach to compute sail shape parameters such as Camber (depth), Draft (position of max depth), and Twist (angle relative to the boom).

03
Adjust and record
Make adjustments in real time. Save scans for later debrief, comparison, or reuse the same settings to increase sail speed and efficiency.

From the fleet
“We trimmed the main off SailScan numbers all weekend and found half a knot upwind.”
“The draft stripes read in seconds. What used to be an evening of photo markup is done before we hit the dock.”
“Camber and twist on every tack, logged. It’s part of our debrief like the GPS track.”
“I’m a weekend racer, not an engineer. SailScan tells me what to ease and when.”
Numbers on your next sail.
