The National Sea Rescue Institute has appealed to the public to avoid the Bos 400 shipwreck near Llandudno in Cape Town.
Spokesperson Craig Lambinon says the wreck is extremely dangerous as it could collapse.
The Bos 400 wreck at Maori Bay on the Atlantic Seaboard is a no go area. Boarding the wreck is prohibited. The wreck poses serious dangers to the public.
NSRI are appealing to the public to avoid the wreck and the surrounding rocks at all costs.
Entering the sea around the wreck also poses serious dangers to the public because of jagged corroding metal that has collapsed into the sea surrounding the wreck.-NSRI
He also said conditions around the vessel, which was South Africa’s largest floating crane, make rescues very difficult.
Lambinon said 3 rescue operations have been conducted over the past month.
The most recent rescue operation was launched on Saturday afternoon, 20 February, following reports of a drowning in progress at the Bos 400 wreck.
When the NSRI crew arrived on the scene they discovered a group of twelve young adults believed to be students from Stellenbosch, and one member of the party, a young man, had suffered a non-fatal drowning accident and he was suffering from hypothermia.
The young man was apparently caught in currents that naturally swirl around the wreck while swimming towards the wreck.
In 2 separate incidents a young female and a young male suffered serious injuries after jumping off the Bos 400 crane into the sea.
The Bos 400 wreck ran aground in June 1994. Salvors salvaged what could be salvaged despite increasing dangerous conditions in and around the wreck until salvage operations were completed and SAMSA (South African Maritime Safety Authority) posted signage prohibiting the boarding of the wreck citing the dangers the wreck poses from the corroding and collapsing metal infrastructure.
