HIDRO gives river surfers full control over their fin setup.

As a team of four tech and surfing passionistas, we are currently working on a way to provide individualisation to the world of surfing. During our intense collaboration and co-creation with surfers and shapers we recognised one thing: Surfing is broken!

Shapers and small manufacturers around the world are building beautiful individually designed surfboards every day. But when it comes to selecting the right fins we face a high-complex and cheaply mass produced portfolio of fins dominated by two large monopolists.

We thought, that we are missing a piece to realise our full potential and to radically reduce complexity when surfers select their board setup. Right now we connect with pro surfers, shapers and board manufacturers to deliver a blueprint for a truly holistic surfing experience.

How Will This happen?

Right now, we believe that the shapers will be the best evangelists and change-makers for our technology. We’re planning to build an app or software that translates the boards style & measurements but also the weight and improvement areas of the surfer into a set of exactly tailored fins. We are also experimenting with a wide variety of materials. At the moment we are playing around with high-tech 3D-printing materials, combining glass and nylon to reach extraordinary stiffness or using slightly flexible materials with shape-memory.

Our technology will be available to every shaper and manufacturer around the world.

We are working together with Strongwater and created custom branded river surf fins for their boards. Quite recently big wave rider David Langer approached us – since then we have been tapping into new ultra-durable materials like titanium to provide the right fin for Dave and other big wave hunters.

In the near future we are going to develop a solution to make this technology available to every shaper and manufacturer across the world. We benefit from our large industry network that enables us to have fins manufactured locally. This helps everyone to reduce shipping costs and reduce the footprints we leave on our planet.

Right now we already ship the first 3D manufactured river surf middle fin that is based on sustainable resources such as castor oil.
