How should divers react to a rip current during a rescue?

Swimming parallel to the shore is the most effective response for a diver faced with a rip current during a rescue. Rip currents are powerful and can quickly pull individuals away from the shore, making direct swimming against the current not only ineffective but also potentially dangerous, as it can lead to exhaustion. By swimming parallel to the shoreline, divers can escape the narrow channel of the rip current and reach calmer water, allowing them to then swim back to shore at a safer angle.

This method is key in ensuring the safety of both the rescuer and the individual in distress. It also follows best practices in water safety and rescue techniques, which emphasize the importance of conserving energy and employing strategic movement in challenging water conditions. Other options may lead to increased risk or hinder assistance, making this approach the safest and most practical in a rip current situation.
