Once the rescue boat is under way what are the main points to remember about approaching and picking up a casualty?

When approaching a casualty in the water, maintain a safe distance to avoid endangering both the rescue boat and the person in need. Position the boat upwind or up-current to control the drift towards the casualty. Always communicate clearly with the casualty to reassure them and assess their condition, and ensure that a proper method for retrieval, such as a lifebuoy or a rescue sling, is ready to use. Finally, prioritize the safety of both the rescuer and the casualty during the pickup process.
