A recently launched research project funded by the Australian Composites Manufacturing Cooperative Research Centre (ACM CRC, Sydney, Australia) addresses the risk of shark attacks on surfers by developing smart composite surfboard fins with embedded shark-deterrent technologies.

Using advanced composites manufacturing techniques, the research project will develop a shark-repellent design integrating miniaturized sensors, electromagnetic systems and illumination features directly into the surfboard fin structure. The composite fin will be a novel product with increased safety while maintaining hydrodynamic performance.

The project is being led by Australia-based partners Gowing Bros (Gowings), University of New South Wales (UNSW, Sydney) and University of Wollongong (UoW). 

“With shark activity on the rise, the project takes a proactive approach to coexisting safely with marine predators, combining cutting-edge materials science with surf safety innovation,” John Gowing, executive chairman at Gowing Brothers Ltd, says. “The project demonstrates how innovatively combining advanced manufacturing, safety innovation and practical commercialization can address real-world marine safety challenges.”

Co-funded by the ACM CRC, the project involves strategic investments in embedded sensors, additive manufacturing equipment and surfboard components, as well as exploration of advanced manufacturing techniques. This includes automated processes for fin and fin box production, surfboard shaping (to incorporate shark-deterrent fins and sensors), composite material deposition and fin finishing, alongside prototype building.

Partners worked on another project together in 2024 focused around travel-friendly surfboard designs.
