HPD confirms death of man pulled from water at Three Tables Beach He said he was one of five divers, with one instructor and a boat captain aboard the Honey Ann on Wednesday, Nov. 6. "The whole thing was just out of control," Arta Kashani said. "I started going to this dive shop to get some training done and during the whole process I told them that I haven't dove in about two years, and I need a refresher just so I feel better," he recalled. He said the dive shop told him they'd do a shallow dive, something easy, but the plan changed last minute, something the dive shop confirmed last week. "They decided to do a 70-foot to 80-foot drift dive that I specifically told the dive master or instructor that I'm not comfortable doing," Kashani said. He said the weather was bad too, with poor visibility. Although uncomfortable with the situation and last-minute change of plans, he jumped in the water with the others. "The current was just pulling everybody everywhere," he said. Kashani said divers were easily 10 to 15 feet away from one another instantly once they jumped in. Kashani was unable to equalize, and the dive instructor in the water told Kashani to go back to the boat with the captain while he went off with the other divers. Kashani said once he was on the boat, the divers quickly disappeared from sight. He recalled the time being around 11:15 a.m. By around noon, Kashani said he asked the captain where the divers were and said he knew something was wrong. He said the boat started going in circles looking for them. But there was no sign of them. Kashani said he heard cries for help in the distance but the captain insisted it was another boat. Coast Guard rescues three from sinking boat near Honolulu Harbor "I was under the impression that the captain called the Coast Guard and he called for help," Kashani said. "He told me there's another boat looking for them and his boss called the Coast Guard and apparently that was all a lie." According to a responding sailboat and the Coast Guard, a nearby sailboat heard cries for help, saw the divers, offered assistance, and called the Coast Guard. The USCG said they were first notified about the situation by the sail boat at 1:33 p.m. and then quickly deployed a helicopter. The helicopter crew arrived on the scene at 1:50 p.m. after being diverted from a training evolution. "At 1:51 p.m. the Honey Ann overheard the transmissions on VHF-FM channel 16 and contacted the command center to report they had been searching for five divers from their charter for 30 minutes (this was the first contact with the Coast Guard from the Honey Ann)," the Coast Guard said in a statement. The CG helicopter instructed the Honey Ann to head towards the chopper. "The Coast Guard Cutter Oliver Berry crew arrived on scene at 1:55 p.m., a Coast Guard Station Honolulu 45-foot Response Boat-Medium crew arrived on scene at 1:58 p.m., then the Honey Ann arrived on scene at 2 p.m. and was able to bring the five divers aboard. The Honey Ann headed back to Hawaii Kai (Maunalua Bay) and reported the divers had no injuries and did not require medical attention. The cause of the incident is currently under investigation by Coast Guard Sector Honolulu. We cannot offer more details about the investigation or its potential outcome at this time," the statement added. Kashani said the five divers were in bad shape after being in the water for over two hours. "One of them was in really bad shape," he recalled. Kashani said only one diver had a wetsuit on, the others had rash guards or shirts. He added he wasn't going to speak out about the incident because he assumed the captain tried to call for help, but was floored and disturbed when he found out he didn't. "If I really knew he didn't do that I probably would have gotten physical with the guy because like that's how angry and stressed out I was, because he almost killed five people if you count me six." Kashani said he was refunded the full amount after leaving a scathing online review. He now wants to alert others about the company.

Following the investigation, the USCG and DLNR can decide whether or not the company will be fined or charged for the incident.
