They held a town hall meeting Tuesday night.
One solution residents brought up was to have the Coast Guard patrol Maunalua Bay and/or set up a neighborhood watch program to monitor activity in the waters.
The town hall meeting was at Hahaione Elementary's cafeteria. Among those there were Keahi Lum's family, including his mom. They listened as residents shared with DLNR and elected officials their safety concerns. One diver says he nearly died after a boat smashed into his.
"Well basically someone tried to murder me. It's that simple," said Deane Gonzalez, a Hawaii Kai resident. "Me and my dive partner. My dive boat was cut loose while we were 60 feet under water while we were in Maunalua Bay diving."
17-year-old Lum died October 4th while diving off China Walls with two friends. A boat struck the Farrington High School student, injured another diver, the third was not hurt.
