SailEdge™ by SailrScience turns your ORC certificate into a digital twin powered by a VPP-class force-balance engine — 850,000+ performance predictions, per-sail attribution, and whole-boat explainability across every sail, every wind speed, every angle. Your boat. Your data. Your decisions.
For racers, sailmakers, and naval architects.
Your ORC certificate is the anchor. Every delta is measured from there.
The runtime hydro layer now carries a boat-integrated Delft Series Hydro backbone, then resolves appendage resistance, heel influence, sideforce/leeway, rudder interaction, and approved wave resistance where the boat data supports it. Drive that doesn’t survive the full force balance doesn’t reach the speed prediction.
CE is computed from actual sail planform geometry — not rig ratios. Each sail carries its own force decomposition: drive, side force, heel moment. Blanketing is real — the model accounts for it. Fly two sails and the engine force-weights them into combined balance.
The 3D view renders it live. Force vectors. CE markers. CLR. Heel. A physics instrument, not a picture of a boat.
The Edge Map distills it into one grid. Green where you’re faster. Red where you’re not. Tap a cell and the panel carries both per-sail attribution and whole-boat outcome, so a gain in drive can be weighed against heel, rudder demand, drag, wave lane status, and balance shift.
Built on ORC certificate data. Not affiliated with ORC. Not a rating predictor.
Start with your ORC certificate. SailEdge™ extracts your hull, rig, and sail inventory, builds your Digital Twin, and delivers your first Edge Map. Add cut sheets when you’re ready to go deeper.

Confirm what you have. Explore what your crew changes. Walk into the loft with data.
Explore →Upload your ORC certificate, pick a sail or change your crew, and see the delta. Green where you’re faster. Red where you’re not. Your edge, quantified.
Explore →Your boat, your sails, your rig — 200+ parameters driving a full force-balance computation. Your entire sail plan, modeled and in your pocket. Select from Delft hull references with visible cross sections. Tune stability per hull family.
Explore →Your design team calibrates the model. Every office in the network sells with it. One calibration, any boat, quantified proof.
Explore →Calibrate once against on-water data. Save the tuning profile. Any rep loads a customer’s certificate and the design team’s physics travel with it.
Explore →Sail tuning for lofts. Hull tuning for architects. The physics scale with the conversation — same engine, different depth.
Explore →Validate the hull side of the force balance. Tune resistance, heel, and stability to match your platform data. Save it as the calibration every sailmaker builds on.
Explore →VPP-class force-balance at every point in the wind matrix. Hull resistance, heel equilibrium, per-sail aerodynamics — 907 formulas, fully server-side.
Explore →Every cell in the Edge Map contains a complete force-balance solution. Tap one. See what drove the delta — which sail, which force, which constraint.
Explore →Built on ORC, not around it. Certificate data is preserved exactly as issued. Every delta is measured from there.
Explore →Three layers of physics documentation — from the core equations anyone can audit, to the aero model that sail lofts calibrate, to the hull response that naval architects validate.
Explore →Built in Annapolis by a sailor who needed it. This started on a boat, not in a lab.
Explore →SailEdge is live. Pick a boat, fly any sail, and see 850,000+ physics-backed predictions — forces, balance, heel, and speed deltas across every condition.
