Glossary
The terms FleetEdge uses, each defined once, in the words the pages use.
One definition per term, in the same words everywhere. A term with a dotted underline links to its entry here. Each entry carries the short definition the pages use and points to the page that defines the term in full.
Vocabulary
The terms, defined once.
- APH
- the certificate’s single-number rating, as a time allowance
- APH Position
- where the boat’s rating sits in the fleet’s distribution, as a percentile
- archetype
- one of the fleet’s eight recurring design types
- Archetype Condition Delta
- the design type’s pace shift under the race’s conditions, in s/nm — lower is better
- archetype condition fit
- how well the design type suited the conditions it met, ranked against its cohort
- cohort
- the boats a figure is computed over — a real entry list, a class, a fleet — named on every figure
- comparative time
- the race-record dimension family — corrected time and rank
- condition fit
- how well the design suited the conditions it met
- condition residual
- the part of a result the measured conditions account for, in s/nm
- crew execution
- the PPI pillar no certificate can compute — what happened against what was expected
- crew pillar
- the crew-execution share of PPI
- crew residual
- what remains after the boat’s evaluated pace is accounted for — negative is faster, in s/nm
- dimension family
- one of the six groups of FleetEdge readings, each reading one aspect of the boat or its racing
- evaluated pace
- the pace the certificate physics say the boat should hold
- HEI
- the Hull Efficiency Index — a drag-derived read of hull form, ranked against its cohort
- mapped IRC
- an IRC entry mapped into FleetEdge’s ORC-based physics view
- observation
- one boat’s result in one scored race, joined to the weather of its race window
- physics evaluations
- pace computed from the boat’s certificate physics
- physics potential
- the PPI pillar that captures hull and sail-plan efficiency, from the certificate alone
- PPI
- the Performance Potential Index
- rating scalar
- the certificate’s reference rating figure
- Regime Affinity
- how favorably a boat suits a defined wind regime
- s/nm
- seconds per nautical mile — pace normalized by distance
- Sail Drive
- the rig’s drive potential on a 0–100 scale
- stability
- how much righting moment the boat carries relative to its displacement
- vintage
- the dated data cut an archetype assignment is computed at — never a display rule
- weather coverage
- the share of the race seen by meteorological observations
- wind regime
- a governed band of wind conditions — upwind, reaching or downwind — a race observation is assigned to
