Computer vision locates your draft stripes. Frontier AI models trace each curve from luff to leech. No manual point placement. Works on mainsails and headsails, port or starboard tack.
Camber depth as a percentage of chord. Draft position as percent aft. Entry and exit angles in degrees. Measured for each stripe so you can see twist from foot to head.
Specific adjustments for cunningham, outhaul, car position, and backstay. Not generic advice. Based on your actual stripe measurements and wind conditions.
Shoot from under the boom or from leeward. Frame all draft stripes luff to leech. The app handles orientation and rotation automatically.
Computer vision detects stripe positions. Frontier AI models trace each curve and compute camber depth, draft position, and entry/exit angles per stripe.
Get trim calls for your specific sail shape. Save the scan, compare across tacks, track changes as you adjust controls between races.
