Two people have been confirmed dead after a charter boat capsized in Hout Bay on Saturday afternoon.
Some 34 others were rescued after the vessel ran into trouble near Duiker Island on Saturday afternoon.
A Hout Bay man described to Eyewitness News how he and his business partner rescued dozens of desperate passengers from the capsized boat.
Alan Tardin, who was on another vessel, received a distress call and responded.
"I shouted at everyone on the boat and told them to get off and swim to my boat. Four people responded and while we were rescuing those four, the boat turned over."
Emergency services said two females who were trapped under the hull were also brought to safety.
Most of those on board were believed to be foreign nationals. A South African man and woman were also part of the cruise.
Western Cape Tourism MEC Alan Winde has called for a full investigation by the South African Maritime Safety Authority.
