Surfboard fins come in various setups.
Some of these configurations include the 1-fin or single fin, the twin fin, the 2+1 fin, and the tri-fin or 3-fin. Each one of these setups offers something unique to your surfing experience.
The use of 1 fin or 3 fins on a surfboard will affect your surfing experience differently.
Fins impact how you are able to manage your board in the water.
A 3-fin surfboard is more stable than a 1-fin surfboard.
In surfboards with 1 fin, there are no side fins. The single fin in the center is not balanced out by other fins.
