Key Intelligence Findings

AIS Blackout Confirmed — 8 Events

Deliberate AIS transponder deactivation detected. Each event represents a period where CIRCLE LINE BROOKLYN was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.

Velocity Fraud — 1 Speed Anomaly Events

AIS SOG field manipulated to broadcast physically impossible speeds up to 102.2 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.

Evasion Navigation — 79 Zigzag Events

Erratic course-over-ground patterns up to 207.8° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.

◐ Dark Vessel Events

Indicator: AIS-MAN-001 · 8 AIS blackout events detected

AIS BLACKOUT

⚠ HIGH SIGNIFICANCE: Dark vessel events represent deliberate AIS transponder deactivation — a primary indicator of intentional surveillance evasion, covert cargo transfer, or sanctions circumvention.

Vessel Type Analysis

AIS declared type · Physical capability vs. observed behavior

Type Mismatch Assessment

AIS Declared Type

vessel_type=37 (Pleasure Craft)

Behavior Consistency

INCONSISTENT — year-round multi-port operations with 166 anomalous events are not consistent with pleasure craft use

Speed Capability

Reported 102.2 kn — physically impossible for Type 37 (max ~45 kn high-performance)

Inspection Priority

HIGH — Recommend USCG/CBSA physical boarding and documentation review
