'Finmas' describes these surfboard fins as well as the new possibilities they represent.

Mas means More in Spanish, and I've decided to name the fins I'm designing Finmas for two reasons:

They are much thicker than normal surfboard fins
These fins can be 3D printed, which could give many more people access to surfboard fins.

Thicker fins create much more lift than normal fins when moving through water. This gives surfers more paddling speed and more ability when surfing on a wave.
These thicker fin designs also make them the first ever fins to be strong enough for surfing when 3D printed! This innovation can be very empowering for surfers in New World Economy areas, because a set of these fins can be printed for just $5 in material. Currently the only way to obtain surfboard fins in these areas is to buy them from a surf shop. If one is lucky enough to have a surf shop in their area, a set of fins costs at least $60 but it's more likely to cost $90 or more.

Better access to surfboard fins might seem like a trival problem, but it's not. Surfing is a sport that can be very empowering for people, especially in places with little access to jobs and education. Learning to surf gives a person something inspiring to do, and along the way one learns how to connect with nature, navigate the intertidal zone and spend time around other surfers.
Becoming a proficient surfer empowers one to be able to teach surfing, guide travelers, learn other languages and connect with more people and areas.
