Race Summary

Wind & Comparable Races

True wind ranged 2.0–13.0 kn (avg 8.5 kn) — light and shifty per the note, closest to race 12 (2026-08-05, avg 7.3 kn, 0.7–16.3 kn, also explicitly logged as "light and shifty") and to race 9 (2026-07-27, avg 9.1 kn, 4.5–15.5 kn); both are used below since neither alone is a close match. This race also carried a five-person crew — the largest in the dataset and explicitly noted as new to the boat — which the data can't separate from technique when interpreting the percentages below.

Overall the boat achieved 65.3% of polar target upwind and 62.8% downwind, both below both comparable races. Upwind VMG averaged 2.76 kn against a 4.2 kn target (66% of target VMG), with TWA running 4.9° wide of target (45.0° vs 40.1°) — similar in size to race 12's 5° gap. The reach was very weak again at 41.9% of target, close to race 12's 40.6% and the second-lowest reach result recorded — two consecutive light-air races now show the reach as the clear weak point of sail. Downwind angle was reasonably close to target (151.7° vs 148.0°, 3.7° deep).

Nine tacks lost 39.5% on average with 6.5s recovery, and six gybes lost 22.7% — both broadly mid-pack for the dataset. One mark rounding was logged, too few for leg-by-leg splits. No Vakaros track was logged for this race, so no start-line position data exists; boat speed just after the gun was approximately 4.7 kn. Trim readings were unremarkable across all three points of sail — heel stayed under 12° everywhere and pitch stayed within about a degree of level — nothing here points at a clear trim explanation for the reach shortfall. The two clearest strengths were downwind angle discipline and tack recovery time; the two most important gaps were reach performance, now weak in back-to-back light-air races, and the overall percentage of target across the board.

Coaching Recommendations

  1. Reach performance was weak for the second race in a row in light air (41.9% here, 40.6% in race 12) — this now looks like a recurring pattern in light/shifty reaching conditions, worth dedicated reach-mode work rather than treating it as a one-off.
  2. Overall percentages of target were below both comparable races across the board — with a new, five-person crew this race, revisit boat-handling roles and communication before drawing conclusions about technique.

Note: this race's saved finish trim was cleared (see the site's data notes), so the logged span above runs about 11 minutes past the registered finish (22:53:31 ADT) into post-race time; the extra minutes are low-speed/idle and don't materially change the figures above, but are flagged here for transparency.
