Inside South Africa’s maritime search-and-rescue system: who does what and how it responds

South Africa has a structured maritime search-and-rescue system that brings together government agencies, volunteer rescue organisations and port authorities to find and assist people in distress at sea. The system is designed so incidents are managed locally where possible and escalated to national coordination when they grow in scale or complexity.

Why coordination matters

Maritime emergencies can cover large areas and conditions at sea can change quickly. The Maritime Rescue Coordination Centre (MRCC) has a central role: it coordinates operations, manages communications for maritime emergencies and works with government and non-government organisations involved in rescue.

MRCC operations and remit

The MRCC operates 24 hours a day, seven days a week with a primary focus on the safety of life at sea. Its responsibilities include coordinating maritime search-and-rescue operations and exercises, monitoring maritime safety information and managing communications relating to maritime emergencies.

When an operation is too large or complex for a local centre, the MRCC can assume overall coordination so that the right mix of resources and organisations are brought together.

Who leads maritime search-and-rescue

The maritime component sits within the wider South African Search and Rescue (SASAR) system. The South African Maritime Safety Authority (SAMSA) is responsible for the maritime search-and-rescue operational function, with the Head of Maritime SAR Operations overseeing the efficient operation of maritime SAR in South Africa’s search-and-rescue region.

The SASAR system’s functions include searching for and assisting crew and passengers of vessels in distress, rescuing survivors of maritime casualties and coordinating medical evacuations from vessels at sea when necessary.

The role of the NSRI and local rescue sub-centres

The National Sea Rescue Institute (NSRI) is a volunteer-based rescue organisation that assists people in difficulty on South Africa’s coastal and inland waters. The NSRI operates rescue bases along the coastline with surf, inshore and offshore rescue craft and runs an Emergency Operations Centre that operates 24 hours a day.

The NSRI Emergency Operations Centre is a first point of contact for Port Control, the MRCC and other emergency call centres, helping to streamline communication between NSRI stations and wider emergency networks.

South Africa’s coastal response is organised through rescue sub-centres positioned along the coastline. The Department of Transport identifies port control offices in Cape Town, Walvis Bay, Saldanha, Port Elizabeth, East London, Durban and Richards Bay as permanent rescue sub-centres. These centres handle operations within their capabilities; secondary rescue sub-centres include NSRI bases and harbour masters operating in their respective areas.

How an emergency is processed

Dedicated alerting posts feed information into the maritime operational structure, including port control offices, coastal radio stations, South African Police Service stations, air traffic service units and the MRCC itself. This arrangement ensures that information about a maritime emergency can be received and passed to the appropriate authorities and rescue resources.

Scale and regional reach

SAMSA’s most recent annual report shows the MRCC-led coordination teams conducted 52 maritime rescue operations and 38 emergency medical evacuations during the 2024/25 financial year.

MRCC Cape Town also serves a regional role: it was inaugurated in 2007 as the Regional Maritime Rescue Coordination Centre for the Southern African region, covering Angola, Namibia, Mozambique, Madagascar and the Comoros in addition to South Africa.

When incidents make national news

The system has been in focus following a recent incident off Mossel Bay in which five people went overboard, with three people confirmed dead and two still missing. In such cases, the coordinated approach allows local rescue units, volunteer organisations and the MRCC to work together to locate people in distress and provide assistance.

Bottom line

For people in South African waters a distress call can activate a multi-layered response: local rescue sub-centres and volunteer agencies respond where possible, while the MRCC and SAMSA provide national coordination and support, and MRCC Cape Town extends that coordination across the Southern African region when required.
