🤖 Claude.ai Analysis

Deep-dive reports built with Claude, querying the same race_vpp_performance and polar_coords_race data behind this site's live Polars, VMG, and Leaderboard pages — the analysis a static table can't show on its own.

The Downwind Outlier
TransPac ’15 is the only race of 36 that beats its own Morrelli & Melvin VPP target. Why — category composition, sample size, sailing angle, wind steadiness, swell, and the fleet-wide pattern behind it.
101.6% of target
Rig Change, March 2020
The Mast Effect
Race-type-matched comparison of VPP performance before and after the 2020 mast install — a real, asymmetric shift: sharply better upwind, slightly worse downwind.
+16.6 pts upwind
Downwind Angle Policy
The Deep Downwind Gap
Pure wind-axis quantification, tactics aside: sailing 145–155° TWA as the default downwind angle instead of the current ~132° habit, pooled across every logged race.
+24% VMG
Polar Data-Quality Check
The Hookup Maneuver
Heat up, then dive deep on the carried speed — a real helm habit, confirmed on six race families, that skews the polar's deep-angle bins toward momentum bursts rather than sustained capability. Tests whether the technique itself actually pays off.
−2 to −4% vs. held angle
