Data note: this is the longest logged session (14:07–23:09 UTC), but there's a ~2-hour gap in the middle (18:30–20:43 UTC) with no valid wind/speed data — likely a break between starts or a period below the underway-speed threshold. The first ~90 minutes of wind data (before ~16:00 UTC, TWS under 3 kn) is also light enough that the direction reading is noisy and less reliable.

True wind conditions

• Across the logged portions, TWS ranged from 0.0 to 24.0 kn (avg 10.0 kn; middle 90% was 2.0–17.6 kn) — the widest range of any race reviewed.
• Direction moved a lot over the session: circular std of 45°, the highest of any race so far. Early on (light air, ~130–150°) it swung through to 200–250° by mid-to-late race — a genuine large shift, though the earliest readings (under 3 kn TWS) are less trustworthy.
• Wind built steadily through the first two hours to a peak around 19–20 kn (18:00–18:20 UTC), then after the data gap settled into a more moderate 6–13 kn for the rest of the race, easing to near-calm (3–5 kn) by the finish.

Tacks and gybes

• 19 tacks, avg duration 10.7 s, avg speed loss 36.9% (the best average loss of any race reviewed), avg recovery 7.9 s.
• Unlike the higher-wind races, tack quality didn't track heading-swing width cleanly here — some wide-swing tacks (e.g. 21:20:51, 115° swing) lost only 13.9%, while a moderate-swing tack (22:11:16, 79° swing) lost 71.5%, the single worst tack of the race, with boat speed dropping from 4.9 kn to 1.4 kn. Likely explanation: that one looks like a stalled/caught-in-irons tack rather than an angle problem — worth reviewing specifically rather than generalizing from it.
• 8 gybes, avg duration 10.4 s, avg speed loss 23.7%. The first gybe of the race (17:11:46, in 15–16 kn breeze) was notably slow at 20 s and lost 48.9% — the slowest, costliest gybe logged all season.

Upwind performance

• Beat boat speed averaged 70.4% of polar target (8,843 samples — by far the largest sample size of any race — avg TWS 8.2 kn).
• Average TWA was 37.4°, essentially matching (very slightly tighter than) the polar-optimal angle of 41.1° at this wind speed.
• Actual VMG averaged 3.05 kn vs. a polar target of 3.99 kn — 76.4% of target VMG, slightly better than the 70.4% boat-speed figure.
• Likely explanation: with angle essentially on target, the VMG shortfall here is squarely a raw boat-speed issue, not a pointing/angle issue.

Power and boat handling

• Average heel while beating was 8.1° — much lower than the higher-wind races (20°+), consistent with the lighter average wind (8.2 kn vs. 13–14 kn) rather than any change in technique.
• Rate of turn upwind averaged 1.22°/s, the lowest (calmest) of any race reviewed, in keeping with generally lighter, steadier conditions for most of the session.
• Data insufficient: no traveler/vang/rudder data is available to say whether power was managed well in the higher-wind opening hour (up to 19.9 kn) before the gap.

Boat trim

• Heel and pitch scale down predictably with point of sail and wind strength, as in other races; no finer within-leg trim breakdown is available in this summary.

Comparison with other races

• Five other races were sailed in broadly similar (light-to-moderate) wind: Race IDs 5 (9.2 kn beat avg), 6 (7.5 kn), 7 (7.0 kn), and 8 (6.5 kn) all fall within a few knots of this race's 8.2 kn beat average.
• Within that group, this race had the tightest upwind angle (37.4°, essentially on the polar target) but was not the fastest relative to target — Race 5 (78.4%) and this race's own 70.4% both beat Race 6 (67.5%) and Race 7 (66.8%), while Race 8 (58.8%, the lightest air of the group) was slowest.
• Race 7's tacks lost much less speed on average (23.5%) than this race's tacks (36.9%) despite similar wind strength. Race 7 only logged 5 tacks vs. this race's 19, so treat this as a pattern to test rather than a firm conclusion — but it's worth a look at what was different about technique or conditions that night.

Coaching priorities

1. Upwind boat speed vs. target (high confidence). Angle was essentially on target (37.4° vs. 41.1° optimal) but boat speed was only 70.4% of target and VMG 76.4% — the gap here is speed, not angle. Action: in this wind range (7–9 kn), focus on speed-building fundamentals — trim and crew weight — rather than pointing higher.
2. The 71.5%-loss tack at 22:11:16 (medium confidence). This single tack lost far more speed than any other logged this season, on a fairly ordinary 79° heading swing. Action: review this specific moment with the crew — it reads like a stalled/missed-timing tack rather than a technique pattern.
3. Tack execution vs. Race 7 (low confidence — small comparison sample). Race 7, in similar wind, averaged 23.5% loss per tack vs. this race's 36.9%. Action: worth a debrief comparing what felt different between the two nights, but don't over-index on 5 tacks vs. 19.
