Key Intelligence Findings
AIS Blackout Confirmed — 4 Events
Deliberate AIS transponder deactivation detected. Each event represents a period where BRANDYWINE was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.
Evasion Navigation — 87 Zigzag Events
Erratic course-over-ground patterns up to 176.9° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.

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
Within or near physical limits for vessel type
Inspection Priority
