SailScan

Faster By Numbers with SailScan

The instrument — 01

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.


The method — 02

Three gestures between a photograph and a faster boat.

Take a photo

Take a photo with your phone and our computer vision model gets to work.

No. 2

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).

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.

SailScan scan history

Appendix

The record stands

Every scan is kept — session by session, sail by sail — ready for the debrief.


Heard on the water — 03

We trimmed the main off SailScan numbers all weekend and found half a knot upwind.
Tom R. — J/111 tactician, San Francisco
The draft stripes read in seconds. What used to be an evening of photo markup is done before we hit the dock.
Sofia M. — Sailmaker, Newport RI
Camber and twist on every tack, logged. It’s part of our debrief like the GPS track.
Henrik L. — Coach, Aarhus DK
I’m a weekend racer, not an engineer. SailScan tells me what to ease and when.
Dana K. — Santa Cruz 27, Seattle
