Major moments——1 ⚑
441 had one MAJOR MOMENT on L2 (gybe #1) — never recovered to entry speed. This single event likely cost more time than all other maneuvers combined. GPS-course boats (181/298) have ·gps treatment on tack/gybe counts and losses; 441's data is clean.

441 entered this gybe at 6.4 kn and never returned to entry speed within +30 s. The boat stabilised around 4.3–4.5 kn and continued degrading. This is the canonical MAJOR MOMENT pattern: a maneuver that permanently lowered the boat's speed profile for the remainder of the run. Total time cost estimated >25 s vs a clean gybe of comparable entry speed.

181 and 298 maneuver consistency: pending GPS-course resolution. Tack/gybe detection on GPS-course boats (181/298) requires heading-independent maneuver identification (sharp bearing-change on GPS track) — the algorithm is defined but not yet validated for these boats on G3. ManeuverDetection.headingIndependent · GPS-track bearing-change method · pending validation
441 held consistent tack recovery across the race (14 s → 15 s, excluding major moment). No fatigue signal in the clean maneuvers. The MAJOR MOMENT on L2 is an outlier event (likely crew coordination failure), not fatigue — it didn't degrade subsequent tack times on L3/L4.

WHAT'S NEW IN V6 — MANEUVERS PAGE

  • 16-point stored SOG sparkline (M1). Replaces the v5 3-point recovery curve. The stored trace runs from −8 s to +30 s at 2 s intervals (16 points) per maneuver. Three annotation markers: entry-speed reference line (dashed green), low-point marker (red dot), recovery-to-entry marker (green dot at the first point returning to entry speed). When recovery doesn't happen within +30 s, the "no recovery" text labels it and the green dot is absent.
  • MAJOR MOMENT sparkline (new). The 441 L2 gybe #1 trace is drawn in red and annotated "no recovery" — visually distinguishable at a glance from a normal recovery trace. Entry speed 6.4 kn, low 3.2 kn, never returned. This is the highest-coaching-value moment in the race data.
  • M2 Maneuver consistency (new). The new section at the bottom asks: did maneuvers hold/improve/degrade from first half to second half? For 441: first half (L1+L2) avg recovery = 14 s; second half (L3+L4) = 15 s — essentially flat, no fatigue signal. The MAJOR MOMENT is excluded from the average as a non-comparable outlier.
  • Leg naming: L1 ↑, L2 ↓, L3 ↑, L4 ↓. "LEG 1 ↑ BEAT" → "L1 ↑ UPWIND" throughout the maneuver log chips.
  • Degraded-entry trace (L2 gybe #2). The second L2 gybe shows 441's entry at 4.4 kn (post-MAJOR MOMENT, not 6.4 kn) — the speed profile consequence of the first gybe cascades into entry state for the second.

DATA STATUS

  • 441 sparkline data is from stored maneuver SOG arrays (ManeuverAnalysis.sogTrace, proposed field alongside M1 · bundle:R-analytics-math). Values interpolated from G3 corpus SOG profiles. 181/298 maneuver detection pending GPS-course heading-independent method. M2 consistency pending 181/298 validation.
  • The MAJOR MOMENT pattern (entry speed never recovered within +30 s window) is a defined classifier — not subjective. A maneuver where maxSogAfterManuever < entrySpeed × 0.98 within the trace window is flagged ⚑.
