Key Intelligence Findings

GPS Spoofing — 24 Position Jumps

AIS coordinates fabricated at impossible locations. Maximum jump of 7,432 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.

Velocity Fraud — 32 Speed Anomaly Events

AIS SOG field manipulated to broadcast physically impossible speeds up to 90.3 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.

Evasion Navigation — 1 Zigzag Events

Erratic course-over-ground patterns up to 81.9° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.

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 163 anomalous events are not consistent with pleasure craft use

Speed Capability

Reported 90.3 kn — physically impossible for Type 37 (max ~45 kn high-performance)

Inspection Priority

HIGH — Recommend USCG/CBSA physical boarding and documentation review
