Your ORC certificate is the anchor. SailEdge™ by SailrScience computes performance deltas from that certified baseline — directional intelligence for sail decisions, not a rating system.

Your ORC certificate provides the polar performance grid, the stability curve, and the rig dimensions that define your boat. Upload it directly in the app — your boat loads with everything the certificate contains. SailrScience treats that data as the certified baseline — the starting point for every computation.
When you change a sail, we don’t re-derive the certificate. We compare two sailplans at the same wind condition, anchored to the same polar grid, and compute the delta. Baseline vs. edge, regime by regime, apples to apples.
The ORC data never changes. It’s the fixed reference that makes the comparison meaningful.

We show you where a sail change makes you faster and by how much. What you do with that information is your call — and your measurer’s.

These are not aspirations. They are behavioral commitments built into how SailrScience handles your certificate data.
ORC remains the authority on measurement, rating, and certification. SailrScience is downstream — a decision tool that depends on the integrity of your certificate, not a replacement for it.
SailrScience requires an ORC certificate as its starting input. Every computation references the certified polar grid. Every delta is measured from the ORC baseline.
The more boats that carry current ORC certificates, the more boats SailrScience can serve. Our incentive structure is aligned with ORC’s mission: broader adoption of measurement-based racing standards.
SailrScience is not a competing standard. It is a downstream application that depends on the quality and availability of ORC data.
Your certificate doesn’t change every time you change a sail. But the Edge Map does. Add a Code 0 to your inventory, run the comparison, and see green cells where it delivers — all without recertification. The delta is computed from the same certified baseline, so the reference stays anchored even as your sail plan evolves.
