The Florida Keys crash left one person dead and three others seriously injured after all 14 teenage passengers were thrown into the water.
The teenager died after the boat hit a channel marker at 6.30pm Sunday and three others are still being treated in hospital with serious injuries, according to the Miami Herald.
Other sailors and emergency crew retrieved the injured after the 29-foot-tall Robalo collided with the marker, capsized and sent the riders flying into the waves.
Lucy Fernandez, 17, died of her injuries Monday, reports the Herald.
Katerina Sofia Puig, 16, Coco Aguilar, 17 and Isabella Rodriguez, 17, are still being treated in hospital, the outlet reported.
Puig is the best scholastic footballer of the year in his division.
Five others – including driver George Ignacio, 52, suffered minor injuries.
Most of the group of friends on the ship — including Fernandez — attended a pair of Catholic schools in the Miami area.
“May you and your beautiful smile rest in eternal peace,” reads a note of warning to Fernandez from his school, Our Lady of Lourdes Academy.
Hundreds of his classmates and teachers gathered to remember the popular teenager at school on Monday night.
An initial report did not indicate that the crash was alcohol-related and an investigation is ongoing.
