MIAMI (CBSMiami/AP) — Miami-Dade County is calling for lights to be installed on the jetty where Marlins star Jose Fernandez crashed his boat, killing himself and two friends.

Mayor Carlos Gimenez said in a memo Monday that the jetty is a “serious threat” to boater safety. The Miami-Dade Police Department made the recommendation for lights.

The Coast Guard began a new analysis last fall of the Government Cut jetties at the southern end of Miami Beach. The new analysis has not been released, but a previous study found that navigation aids in the area met boaters’ needs.

CBS4 investigative reporter David Sutta took a boat ride at night. With the jetty right in front of them, he could barely see. It was a powerful demonstration of how different boating at night can really be and how much difference lighting can make.

The Miami-Dade Fire Rescue boat crew told CBS4 Fernandez likely didn’t see the rocks until the last second.

Past studies concluded the jetties aren’t hazards for boat operators following standard navigational rules.

Fernandez, 27-year-old Emilio Macias and 25-year-old Eduardo Rivero, 25, died when the 24-year-old pitcher’s 32-foot boat struck the jetty just after 3 a.m. Sept. 25.

Fernandez’s blood ethanol level was between .14 percent and .16 percent, or two times the legal limit, according to toxicology results. The Miami-Dade Medical Examiner’s Office report also noted Fernandez and Rivero also had cocaine in their system.
