True wind conditions

• This was a short race (~90 minutes logged). TWS ranged from 0.1 to 12.7 kn (avg 6.6 kn; middle 90% was 3.8–9.2 kn).
• Direction oscillated within a 190–240° band (circular std 20°, mean 219°) rather than trending cleanly one way — a genuine oscillating shift, not a steady veer or back.
• Wind built from 6.2 kn at the start to a peak of 9.0 kn (22:00 UTC), then eased through the second half, dropping to 3.6 kn briefly near the finish before recovering slightly.

Tacks and gybes

• 5 tacks, avg duration 10.4 s, avg speed loss 23.5% — the best average tack loss of any race reviewed — and avg recovery 3.6 s, the fastest average recovery of any race reviewed.
• The result is a bit bimodal rather than uniformly good: three tacks were excellent (13.0%, 8.9%, 17.2% loss) and two were considerably worse (39.2%, 39.1%). Interestingly, the two best-executed tacks (21:54:59 and 22:20:33) both had wide heading swings (110° and 121°) with low loss — angle width alone didn't predict outcome here.
• 2 gybes, avg duration 9.5 s, avg speed loss 16.0% — both clean, no standout issues.

Upwind performance

• Beat boat speed averaged 66.8% of polar target (1,821 samples, avg TWS 7.0 kn).
• Average TWA was 43.7°, very close to the polar-optimal 42.1° at this wind speed — only 1.6° off, one of the tightest angle matches reviewed.
• Actual VMG averaged 2.61 kn vs. a polar target of 3.58 kn — 72.9% of target VMG, better than the 66.8% boat-speed figure, consistent with the near-perfect angle.
• Likely explanation: with angle this close to target and tacking execution the best of any race reviewed, the remaining gap to 100% target speed looks like a straightforward raw-speed shortfall rather than a technique or angle issue.

Power and boat handling

• Average heel while beating was 13.1°, broadly in line with other light-to-moderate wind races at similar strength.
• Rate of turn upwind averaged 1.31°/s — unremarkable, mid-range for the dataset.
• Data insufficient: no traveler/vang/rudder data available to assess power management directly.

Boat trim

• Reach performance this race was notably low (52.2% of target, though only 488 samples) — the weakest reaching performance of any race reviewed. No finer trim breakdown is available to explain why.

Comparison with other races

• Four other races were sailed in broadly similar (light-to-moderate) wind: Race IDs 4 (8.2 kn beat avg), 5 (9.2 kn), 6 (7.5 kn), and 8 (6.5 kn).
• This race had by far the best tack execution of the group (23.5% avg loss vs. 31.8–36.9% for the others) and one of the tightest angle matches to target — yet its boat speed relative to target (66.8%) was still only mid-pack, better than only Race 8 (58.8%).
• Season-level observation: across nearly every race reviewed so far, raw boat speed relative to polar target — not tacking technique or upwind angle — has been the most consistent limiting factor. This race is a clean example: best-in-class tacking and a near-perfect angle, but still under 70% of target speed.

Coaching priorities

1. Raw boat speed vs. target (high confidence). Angle (43.7° vs. 42.1° target) and tacking (23.5% avg loss, the best reviewed) were both strong, yet boat speed was still only 66.8% of target. Action: since technique here is already close to the boat's best, this points toward checking sail shape/trim or crew weight for genuine speed rather than more tacking or pointing drills.
2. Tack inconsistency (medium confidence). Two of five tacks lost ~39% while three lost under 20% — a real split rather than a consistent level. Action: review what was different about the two weaker tacks (21:56:29, 22:05:30) vs. the three clean ones.
3. Reach performance (low confidence — small sample). Reach boat speed was only 52.2% of target on just 488 samples, the weakest of any race reviewed. Action: worth a look, but the small sample size means this could be a short, unrepresentative stretch rather than a real pattern.
