Race Summary

Wind & Comparable Races

True wind ranged 4.5–15.5 kn (avg 9.1 kn) — light-to-moderate and, per the race note, notably shifty. Race 5 (2026-06-24, avg 9.1 kn, 3.1–16.4 kn) is an almost exact match on average wind, making it the best comparable on record, though it was sailed with four crew rather than three.

Overall the boat achieved 71.5% of polar target upwind but only 62.3% downwind, the latter well below race 5's 79.1%. Upwind VMG averaged 3.06 kn against a 4.28 kn target (71% of target VMG), with TWA running 4.7° wide of target (44.4° vs 39.7°). Downwind angle deviated sharply: average TWA of 170.6° against a 148.7° target is 21.9° deeper than optimal — the largest downwind angle gap recorded in this dataset, consistent with the "shifty night" note and possibly reflecting frequent angle changes chasing pressure, though the data can't distinguish that from sustained by-the-lee sailing.

Eight tacks lost 34.2% of speed on average but recovered quickly at 4.8s; no gybes were logged at all this race, unusual given the run had nearly 2,000 samples logged. Four mark roundings were logged, still too few for reliable leg-by-leg splits. The Vakaros line was never pinged this race, so no distance-to-line figure is available; boat speed just after the gun was approximately 4.5 kn. Heel while running averaged just 1.0° — unusually flat, alongside the very deep average run angle noted above; the two appearing together is consistent with sailing close to dead downwind for much of the run, though the data doesn't confirm cause and effect. The two clearest strengths were upwind speed as a share of target and fast tack recovery; the two most important gaps were the large downwind angle deviation and the complete absence of gybes in a race with substantial run time.

Coaching Recommendations

  1. Downwind TWA averaged 21.9° deeper than target (170.6° vs 148.7°), the largest angle gap on record — review whether this reflects genuinely shifty conditions or a tendency to over-sail depth, and work on holding closer to the target angle.
  2. Zero gybes were logged despite ~2,000 run samples — on a shifty night, review the track/video for missed gybe opportunities to stay in pressure or lifts.
