In this episode, I spoke to Jermome and Leopold, who design foils for Duotone. We discuss their design philosophies and approach, as well as the evolving technologies used to design and build foils for wing foiling, downwind foiling, prone foiling and pump foiling. We also discuss why they don't currently produce foils for racing.We also discuss how they respond to the market and balance the need to deliver what the market currently needs or expects while also looking ahead to educate the market and introduce new approaches and designs for improved performance. Jermone and Leopold also discuss their current foil range and their applications. It’s a particularly interesting chat for those looking to understand the thinking behind foil design and the decision-making process and steps taken in transitioning from a product idea to the launch of a new foil. Enjoy!
