A Miami tugboat captain pleaded guilty in 2026 to seaman’s manslaughter in a 2025 Biscayne Bay collision that killed three girls from a sailing camp, with sentencing set for October 13, 2026.
Yusiel Lopez Insua, 46, admitted to causing the July 28, 2025, crash by violating maritime safety rules, including using his cellphone and failing to maintain a proper lookout, according to federal prosecutors and court filings. The incident occurred when Lopez Insua’s tugboat, pushing a barge loaded with construction debris, struck a sailboat carrying 19-year-old counselor and five girls aged 7 to 13. Three children drowned after the barge overturned the sailboat, which had lost wind and stalled in the tugboat’s path.
Guilty Plea and Legal Context
Lopez Insua, who changed his plea from not guilty to guilty on July 21, 2026, faces up to 10 years in prison for the manslaughter charge. Prosecutors recommended a sentence of one year in prison followed by six months of home detention as part of a plea agreement, though the final decision rests with the court. Yusiel Lopez Insua … admitted that his criminal failure to follow basic maritime safety rules caused this deadly collision,
said U.S.
Erin Ko Han’s uncle, Alvin Wu, stated that Lopez Insua’s decision to avoid trial spared the families from reliving the trauma, according to Local10.com. Attorney Walter Reynoso, representing Lopez Insua, emphasized his client’s remorse, noting that the captain had “near-misses” in the same area prior to the crash. The indictment also cited obstructed visibility in the tugboat’s pilothouse due to a deckhouse and crane, as well as the absence of a dedicated lookout crew.
Circumstances of the Crash
The collision occurred as the sailboat, part of a youth sailing camp, was stranded in Biscayne Bay. Investigators reported that Lopez Insua’s cellphone showed internet activity during the crash, including at the time of impact. The barge, weighing 149 gross tons, overtook the sailboat, submerging it beneath the hull.
Court filings revealed that Lopez Insua had previously been involved in “near-misses” in the same waters, though no prior charges were mentioned. The barge’s lack of radar or camera systems, combined with the obstructed view, contributed to the accident. The Miami Yacht Club noted the children were in their final week of camp, with the tragedy occurring just days before their departure.
Aftermath and Legal Proceedings
The crash remains the subject of at least one civil lawsuit in Miami-Dade County, as reported by Local10.com.
Prosecutors highlighted the rarity of such collisions in U.S. waters, noting that in 2024, only 43 boating fatalities resulted from vessel-to-vessel crashes out of over 550 recreational boating deaths. The case underscores the risks of inadequate lookout protocols and the consequences of distracted operation, as Lopez Insua’s cellphone use was a key factor in the indictment.
As of July 2026, the court has not released further details on the sentencing hearing scheduled for October 13.
