Hidden ShapeThe hidden shape of the fleet.
The kinds of boat that keep appearing when every hull is measured the same way.
The shape of the fleet, before the scoreboard has anything to say.
If the rating accounts for the boat, everything else is the crew.
The Offshore Racing Congress was founded on a single, elegant idea: if the rating system accounts for the boat accurately enough, then the difference between two corrected-time results is the crew.
Tactics, preparation, execution, and the thousand small decisions that separate a podium finish from the middle of the fleet.
For decades, that principle has been a design goal without an external measurement layer. ORC produced among the most technically sophisticated rating certificates in the sport — hull geometry, rig dimensions, stability curves, velocity predictions — and the crew's contribution stayed unquantified at fleet scale.
The certificate describes what each boat is. Force-balance physics evaluates what each boat should do. Race results show what actually happened. What the three authorities could not do on their own was reveal, boat by boat and event by event, what the crew contributed inside the gap.
Every fleet has hidden structure.
When you examine the fleet at scale, patterns emerge that no individual certificate reveals. Boats cluster not by class division or rating band, but by kind of boat — the specific combination of hull efficiency, rig power, and stability that defines how each boat converts wind into speed.
Eight distinct performance archetypes emerge from the data. FleetEdge publishes them as eight recurring answers to the same hydrodynamic constraints — maintained over eleven internal classifier cells — each taught on its own card on the Fleet Archetypes page. How eleven resolved into eight →
Built from the certificate up.
When you follow a single boat through FleetEdge's analytical framework, the journey begins with what ORC already knows. The certificate provides the hull dimensions, rig geometry, and stability parameters that define the boat's rated identity.
SailEdge's Delft Series force-balance model takes those measurements and computes speed deltas against the ORC baseline at every wind angle — revealing where the hull form's physics signature diverges from the certificate.
The gap between what the force-balance analysis indicates and what the race results show is where the structure reveals itself. FleetEdge's structural features capture hull efficiency, rig performance, stability characteristics, rating position, and the deltas between the ORC baseline and empirical reality. The gap is also where the claim stays honest: it bounds what the crew lane owns without naming a cause — no single decision, sail, or moment is identified by it.
FleetEdge groups the boats into the 8 canonical archetypes by their structural similarity.
The pipeline itself is taught once, on How It Works; the full derivation lives on Methodology.
What this looks like on the water. When FleetEdge's classifier processed the 2025 ORC World Championship at Tallinn, the two published class titles went to boats in two different archetypes — AEROSTREAM and AEROCORE — and Class C carries no first-place row in the current published view (standings as captured in FleetEdge's published view). See the worked example on the Fleet Archetypes page →
Tallinn is an illustration. The fleet-wide test — podium share against participation share across every scored race in the corpus, with confidence intervals and the caveats stated — is published in the validation analyses.
Every analyzed boat. Every scored race in the archive.
A single race is an anecdote. A season of racing is data. FleetEdge analyzes its full fleet across every event in its race archive, accumulating confidence as the fleet deepens and the conditions vary. One observation tells you what happened; hundreds of observations tell you what is true.
Archetype identity comes from the certificate; confidence comes from the racing. A boat's archetype assignment is computed from the structural inputs of its certificate at a stated vintage — race results never move it. What accumulates with racing is evidence: condition fit, the Performance Potential Index, and the crew residual all sharpen as observations grow — the more races a boat completes, the more precisely FleetEdge can distinguish design contribution from crew contribution. A re-measured certificate or a model revision may legitimately move an assignment, and the assignment is dated when it happens.
The deeper the fleet, the stronger the signal.
FleetEdge becomes more valuable as the fleet grows. Every boat that enters the system adds dimensional data to the model. Every race that is processed sharpens condition-fit evidence and strengthens the confidence in crew performance isolation. The signal improves not just for the new entrant, but for every boat already in the fleet.
For class associations and regatta organizers, this creates a compounding return: as a fleet's analyzed population grows, its archetype distributions firm up, finer structure inside each archetype becomes visible, and the statistical foundation supports more demanding analytical questions at fleet scale.
The ORC promise — rate the boat fairly, and the best crew wins — is not just a philosophy. With FleetEdge it becomes a measurable reading, at its stated scopes. FleetEdge does not validate the ORC methodology or certify any individual rating; it alters no rating and no score — ORC remains the rating and scoring authority.
