Key Intelligence Findings

AIS Blackout Confirmed — 5 Events

Deliberate AIS transponder deactivation detected. Each event represents a period where GREATER SCOTT 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 83.8 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.

Evasion Navigation — 91 Zigzag Events

Erratic course-over-ground patterns up to 166.9° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.

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 206 anomalous events are not consistent with pleasure craft use

Speed Capability

Reported 83.8 kn — physically impossible for Type 37 (max ~45 kn high-performance)

Inspection Priority

HIGH — Recommend USCG/CBSA physical boarding and documentation review
