We are innovating to make the most sustainable surfboards in the world!

The concept behind Sine Surfboards began just after I buckled a brand-new board in early 2020. This prompted me to do some research about surfboard materials and construction. I was quickly drawn to the beauty of wooden surfboards and noticed a small resurgence in the use of wooden materials over recent years.

Many of the surfboards marketed as ‘wooden’ today involve the addition of a thin wooden veneer between the foam and fiberglass. Although stunningly beautiful, these boards have little sustainable advantage. Hollow wooden surfboards eliminate the need for a PU or EPS foam core by supporting the top and bottom deck with internal truss structures. Both beautiful and sustainable, these boards are not widely used today because of their usual weight, high material cost and the skilled craftsmanship required, making them a niche product.

Prompted by my engineering education I began brainstorming alternate manufacturing methods that could address some of the performance and manufacturing issues associated with hollow wooden surfboards. With help from my uncle John Dennison and a friend Alastair Pilley we were able to identify a new cnc machining technique that would allow us to optimise the internal structure of hollow wooden boards to increase flex and strength whilst reducing the total weight. Over several months of learning and prototyping, we were able to directly convert a shaper’s file into a hollow wooden board milled directly from sustainably sourced Paulownia timber.


With sustainability in mind, it was a wholesome experience seeing these boards come to life on Sydney’s local breaks, but this wasn’t enough. We thought that others might appreciate and enjoy these creations and began thinking about taking these boards to market. After scouting the internet to saturation, I reached out to some of Australia’s best shapers to learn more about surfboard shaping and manufacturing. Michael Psillakis and Steve O’Donnell in particular were a huge help. The deep dive into the world of shaping was interesting to say the least! From October 2020 we began making and testing our own designs and through several iterations, each with many days of enjoyable product testing, we became proud of our first models the Fishy, Eggplant and the Big Z. More recently we have been working to produce industry legend Steve O'Donnell's shapes with our technology.



Sine surfboards are high performance, leaving some of surfing's big names including Declan Wyton and Layne Beachley excited with our innovation. They are the most sustainable on the market, they produce less than 0.5 kg of waste during manufacturing, are more than 95% biodegradable and are better than net zero emissions.



Our boards address the problems of plastic pollution in our oceans. By eliminating the need for a foam core and by reducing the amount of epoxy used, we believe that our surfboards are the most sustainable boards on the planet (of course, we are open to any contradictions). Each board we produce is made with the highest care and attention to detail and our surfboards are made to last for many years.
