Well known yzerfontein man dies at harbour after boat capsized

It sounds like you're referring to a tragic incident that occurred in Yzerfontein, a coastal town in South Africa. Unfortunately, it's not uncommon for accidents to happen at sea, and it's always devastating when someone loses their life.

Can you tell me more about the incident? What was the cause of the boat capsizing, and were there any other people on board who survived?
