US Coast Guard Alaska Maritime Rescue Tracker & Drift Analyzer

DATUM: 57°47'N 152°24'W

LEEWAY HDG: 135° SE

SEARCH ZONE: 15.0 NM SQ

Incident Grounding: Based on USCG emergency response off the Alaska island coast where a 15-year-old survivor was found alive after days at sea following a fishing vessel capsize. Adjust vector dynamics to reconstruct drift leeway and search geometry.
