CPA_ais-244690213|ais-244750015The two ships will approach within ~7 min to a distance of only ~18 m: “APRIL” (7 kn) ↔ “ARISTO” (5 kn). In reciprocal/intersecting travel, such a close approach is a sign of collision risk. It is an automatic CPA calculation — not a confirmed event, but an early signal. 📋 EVIDENCE (AIS · aisstream): “APRIL” MMSI 244750015 @ 53.2459,6.2832 · 7 kn · heading 79° | “ARISTO” MMSI 244690213 @ 53.2501,6.3227 · 5 kn · route 262° | Measurement: 2026-09-21 09:04:37 UTC
