Miami Tugboat Captain Charged With Seaman’s Manslaughter in Fatal Camp Sailing Collision

Federal prosecutors have charged Miami tugboat captain Yusiel Lopez Insua, 46, with seaman’s manslaughter over a July 2025 Biscayne Bay collision that killed three girls from a Miami sailing camp. The U.S. Attorney’s Office for the Southern District of Florida alleges Insua was pushing a barge loaded with construction debris without a designated lookout and lacked a clear view when a small sailboat carrying a 19-year-old counselor and five girls stalled in the barge’s path between Miami and Miami Beach. Prosecutors say Insua did not see the sailboat before impact; the counselor and two girls were dragged under the barge but escaped, while three girls, ages 7 to 13, were trapped in the wreckage and drowned despite efforts to rush four of the children to a hospital. A forensic review found Insua’s cellphone had internet activity around the time of the crash, and prosecutors characterized the case as a “preventable loss of life” tied to failure to follow basic maritime safety rules, with the seaman’s manslaughter charge carrying a potential 10-year federal prison sentence. The case highlights ongoing concerns about commercial vessel operations in crowded recreational waters and comes against a backdrop of more than 550 recreational boating deaths nationwide in 2024, only a small fraction of which involved vessel-to-vessel collisions.
