Your ORC certificate is the baseline. The SailEdge™ Edge Map measures every sail against it — at every wind speed and angle. Green where you gain. Red where you don’t. The exact delta in knots, meters per second, or seconds per mile, with one-tap explainability from per-sail attribution to whole-boat outcome.
Explore Your Edge How it works →The Concept
The Edge Map is a performance delta grid. Your ORC certificate sets the baseline. Each cell shows how a specific sail performs at a specific angle and wind speed — relative to that baseline. Green is faster. Red is slower. The number is the margin.
Sitella — Cape 31, Key West class winner. Real boat, real certificate, real Edge Map.
Every cell in this grid is the output of a complete force-balance solve — drive, side force, heel equilibrium, a DSH-backed calm-water backbone with bounded follow-on lanes, resistance, depower, and bounded wave-lane status when it matters — iterated across your ORC polar. The color is the headline. The physics behind it is one tap away.
Your certified polar — the baseline the racing world trusts. Every speed at every angle, straight from the certificate. The ruler everything else is measured against.
What your actual inventory does at each wind speed and angle. Green where your sails beat the baseline. Red where they fall short. The delta in knots.
The comparison layer. Maps the gap across the entire wind range, groups cells into regimes, and surfaces the headline: “59 cells faster, 20 neutral, 9 slower.” Tap any cell to drill in.
One trusted baseline. Your real sails. The full picture — measured, not guessed.
Performance across every wind speed and angle your ORC polar defines. Not a single number — the complete picture, one cell at a time.
Tap a cell. See which sail drives the delta — main, headsail, or code sail — with drive force and heel moment broken down individually, then read the whole-boat outcome beside it.
When the physics hit a boundary — hull speed cap, underpowered baseline, high rudder demand, or missing approved wave input — the cell tells you. Amber means boundary-limited. Grey means the model suppressed a meaningless result.
Invalid sail combinations are flagged, not hidden. If a reaching kite produces drag instead of drive at that angle, the model says so rather than painting a misleading green cell.
Every sailor reads performance differently. The Edge Map lets you toggle between three result formats — knots, meters per second, and seconds per mile — with one tap.
Knots is the default. Fractional knots show the raw speed delta: +0.43 kt means you’re nearly half a knot faster at that condition. Intuitive for anyone who reads a knotmeter.
Meters per second is the SI standard — useful when working with international rating offices or comparing against ORC VPP output directly.
Seconds per mile flips the question. Instead of “how much faster am I?” it answers “how many seconds do I save per mile sailed?” At Farr Designs’ recommendation, we added this view because it maps directly to what matters on a racecourse: time on the water. A +26 s/mi delta at TWA 52° in 10 kt means that sail change saves you 26 seconds every mile you sail at that angle and breeze. Over a 5-mile windward leg, that’s over two minutes.
All three formats use the same underlying physics. The unit toggle changes presentation, not computation. Cell intelligence, confidence indicators, and sail plan attribution all work the same regardless of which unit you choose.
The delta is the headline. Everything behind it — per-sail attribution, whole-boat outcome, and confidence state — is one tap away. Under the Hood →
Squaretop mains, membrane headsails, Code sails, asymmetric kites — the aero model recognizes modern planforms and credits them accordingly. A squaretop main gets different treatment than a pinhead. A membrane genoa isn’t a Dacron genoa. Sailmaker-provided shape and material metadata flows into the model when available, and conservative defaults apply when it doesn’t.
Tap any cell and see everything behind the number. Per-sail drive breakdown, confidence indicators, sanity checks, and the aero model that produces them.

Three numbers change the conversation: cells improved, average delta gain, cost per tenth of a knot. A $12K purchase that lifts 40 cells by 0.3 kt is a different proposition from one that lifts 10 cells by 0.1.
When the budget covers one sail, not two, the Edge Map shows which purchase closes more gaps across the wind range. Same baseline, same boat — apples to apples.
Zoom out and the Edge Map becomes a full inventory assessment. Where you’re covered, where you’re exposed, where the next upgrade delivers the most value.
Every sail decision is a trade-off. The Edge Map makes it visible. Crew weight is now part of the same what-if workflow — one checkbox, no Expert Mode needed. Share your findings — screenshot, summary, and a live link — so your sailmaker sees exactly what you see. When your loft is a SailEdge partner, the results reflect their calibrated aero models — not just generic coefficients.
