Inside Australia’s Project Building Shark-Repellent Surfboard Fins For Surfers

Article excerpt

Australian researchers are embedding sensors, lights, and electromagnetic systems into surfboard fins to repel sharks without compromising surfing performance. The project tackles a growing concern for surfers as shark encounters have increased along Australian coasts in recent years. The fins use technology to deter sharks based on their sensory systems, electromagnetic pulses that disrupt their ability to detect electrical signals from prey. Early testing suggests the devices can reduce shark interest while maintaining the hydrodynamic properties surfers need. The innovation represents a middle path between safety and the sport itself, avoiding the blanket beach closures that have frustrated the surfing community.
