Inspiration behind FinnFin Diving
The inspiration to FinnFin Diving started from decades of diving experience across multiple diving disciplines. In all these disciplines the available diving fins had recurring problems and shortcomings:
- The diving fins are not ergonomic: they are either efficient OR comfortable. The most efficient competition-level fins are so painful, that the athletes don’t put them on until the last minute before their dive start. The comfortable fins on the other hand are so inefficient, that one is almost better off diving without any fins.
- Diving fins’ efficiency has been unoptimized, leaving multiple weaknesses: power generation has primarily been done in the front/down-kick using only front side muscles (abs, quads…), power transfer from muscles into propulsion has had multiple weak links and hydrodynamics has been far from optimized.
- The adjustability of diving fins has been very limited. Diving fins are often permanently attached stand-alone packages e.g. foot pocket glued to the fin blade. This means that when buying multiple fins for different applications, or upgrading existing equipment, the diver also needs to re-purchase those parts that (s)he was already comfortable with (e.g. foot pocket). Additionally, there are no standards available that could be used to compare diving fins e.g. for their size, stiffness or bending characteristics. This forces divers to buy a ‘pig in a bag’ when purchasing diving fins, and only finding out after the purchase if the fin blade was good or not, and if the foot pocket fits the leg or not.
Divers have grown to accept these and many other shortcomings as unavoidable necessary evils, and there has been very limited innovations in the industry attempting to resolve these.
Later, after gaining experience from cycling, it became clear that these shortcomings were not inevitable:
- Cycling shoes and riding positions can be efficient AND comfortable at the same time
- Clipped cycling shoes and pedals allow generating lot’s of force also from the back-side muscles (hamstring, glutes…)
- Cyclists are obsessed with seeking competitive advantage from better power transfer efficiency, aerodynamics and weight
- Vast majority of components are standardized and interchangeable, even those used in top competitions where no power transfer loss caused by weak interfaces could be tolerated
Using this cycling analogy: if bicycles were made like typical diving fins,
- you would not know what gear your bike would have when you order it
- every new bike would come with their own, permanently attached cycling shoes
- cycling shoes would not be shaped to hold a human foot comfortably
- changing the gearing, shoes or suspension set-up on your bike would require buying a complete new bike(+shoes)
- the parts in the drive chain would be only loosely attached, causing a massive power transfer loss
- the pedal would allow generating force from 10‑o’clock to 2‑o’clock positions.
- the riding position would be fixed up-right, causing unnecessary aerodynamic drag
With these inspirations in mind, FinnFin Diving was founded to make ergonomic, efficient and adjustable diving fins.
