Data Definitions
Every figure on FleetEdge names its cohort. This page defines the vocabulary.
Every fleet has a fingerprint.
Every count on a fleet page declares what it counts — start where your boats sail.
Hidden Shape52 dimensions distilled into 11 performance archetypes.
How the corpus clusters before the results arrive.
Read the shape of the fleet before the scoreboard reads it.
Different pages answer different questions, so they count different cohorts. A country page counts boats by certificate provenance — the national flag on the paperwork. A fleet or race page counts a competitive cohort — the boats that sail together, which can include entries from other countries. Two totals that differ are not a contradiction; they are two well-posed questions with two correct answers.
That only works if every figure declares its scope. Across FleetEdge, each figure carries three things: the cohort it counts, the denominator behind any percentage, and the date of the published data view it comes from. This page defines the terms those labels use.
The terms behind the counts.
ORC-rated
A boat carrying an ORC certificate in the analyzed corpus. ORC-rated boats bring measured hull, rig, and stability data — the physics foundation of the analysis.
Mapped-IRC
An IRC-rated boat matched to its ORC design family using measured hull dimensions — length, beam, draft, and displacement ratio — and carrying a projected physics profile from that family. FleetEdge never reads IRC rating values; the match uses public dimensions only.
Classified / unclassified
A classified boat has been assigned to one of the eleven performance archetypes. A boat remains unclassified when its available data is insufficient for a confident assignment. Archetype percentages state their denominator — the classified pool or the whole fleet — wherever they appear.
Race data vs. authority counts
An authority count reflects certificates issued under a national authority — the registry view. A race-data count reflects boats linked to actual event results — the competition view. A boat can hold a certificate and never race; the two counts answer different questions.
Scope labels
National fleet view counts by certificate provenance (flag). Global fleet view spans the full analyzed corpus. Domestic competitive fleet is a competition cohort anchored to a country’s racing circuit — and can include foreign-flagged entries. Race and event sections count only the boats in that event.
As-of date
Every macro figure cites the date of the published data view it comes from. Race and event sections cite their own publication vintage separately — see below.
Why two totals can both be right.
Consider one boat: flagged in one country, racing a neighboring country’s offshore circuit, entered in a championship abroad. She appears in her flag country’s national fleet view, in the neighboring circuit’s domestic competitive fleet, and in the championship’s race cohort — three pages, three cohorts, one boat, no double counting within any one view.
The rule of thumb: before comparing two FleetEdge figures, compare their scope labels. If the cohorts differ, the numbers are answering different questions — and should differ.
Archetype names have vintages.
FleetEdge’s archetype taxonomy is maintained over time: as the analysis is refined, an archetype’s name or description can be revised. Race and event sections deliberately render the archetype view as published nearest that event’s date — the analysis the fleet would have seen at the time — and say so in their provenance line. Current fleet surfaces always render the current taxonomy.
This means an older race section can carry an archetype name that no longer appears in the current taxonomy. That is by design, not an error: the name is the as-published vintage. For example, analyses published in 2025 include the archetype BALANCECORE; in the current taxonomy the same design group is named STEELCORE, with a revised description.
Reading a race section: the provenance line beneath a Race Archetypes section tells you which published view it reflects. When it reads “as published” with a date, names and shares are of that vintage — compare them with other sections of the same vintage, not with today’s fleet view.
What kind of claim am I reading?
Alongside its scope, every analytical card on FleetEdge carries one of five public evidence badges — a closed, stable lexicon that tells you whether a figure is a live fleet-wide measurement, a result under on-site validation, a structural readout without race attribution, a low-sample structural view, or a forward-looking pre-race scenario. The badge lexicon is defined on the How It Works page.
Read the fleet with confidence.
Every figure names its cohort, its denominator, and its date. That is the standard.
