Four fishermen have died after their trawler ran aground near Mossel Bay.
A search and rescue operation is now underway for a missing crew member.
Spokesperson for the South African Maritime Safety Authority (SAMSA) Sicelo Fayo says the search commenced following a distress signal received from the fishing vessel DIJAANDA.
He says the National Sea Rescue Institute (NSRI) managed to locate the vessel stranded on the rocks near Mossel Bay in the Gouritzmond area.
Fayo says NSRI teams in Mossel Bay and Stilbaai have launched a search and rescue operation early on Tuesday for the missing man.
He says one crew member survived and sustained injuries.
The names of the deceased are not yet known.
