Animated 1/12° surface current (Copernicus GLORYS — Bohlen's preferred source over RTOFS). Dashed white = rhumb;
green = current-optimal crossing (Zermelo least-time through this field, current-only — not a wind route); gold band = RHUMB corridor (±30 nm at 37°N). Click for speed. Frozen pre-race research (RRS 41).
⚠ Current only — NOT a wind/race route.
