A safety zone will be set up at the San Diego Parade of Lights for the next two Sundays.
People and vessels won't be allowed to enter the zone between 5:30 p.m. and 8 p.m., both Sundays.
Organizers are dedicating this year's parade to eight-year-old Anthony DeWeese. He was killed during last year's parade, when a coast guard boat crashed into the vessel he was in.
The Dec. 20 collision occurred as boats were gathered in San Diego Bay for an annual Christmas parade of decorated boats.
The 33-foot Coast Guard boat was responding to a report of a grounded vessel when it rammed the 26-foot Sea Ray pleasure boat.
Witnesses have said the Coast Guard boat was speeding.
Anthony Cole DeWeese was struck in the head and died at a hospital after the crash.
