Determining the Fin Setup
Single Fin:
The Single Fin setup is the oldest and original design. It was first used to give the board balance similar to the keel of a sailboat. Typically, the single fin setups consist of a larger fin to provide more balance for the board due to the fact that is the only fin underneath the board. This fins size provides thourough turns in larger surf but limits the manuverabiliy in smaller surf and tighter turning situations.
Twin Fin:
The twin fin set up is most commonly seen in surfboards that support a fish tail. The twin fin set up provides the surfboard with the ability tyo ride straight but also make fast turns when needed. After becoming more comfortable with the twin fin setup the rider can gain speed down the line and make fast quick turns whenever they wish..
The thruster fin setup consists of three fins, two symmetrically aligned on either side and one placed further back in the middle of the top two. The thruster The thruster fin setup rides similar to the twin fin setup but also provides smoother turns thanks to the thrid fin situated closest tot he surfboards tail.The thruster fin set up is the most common fin set up as it adapts fairly easily to any type of surf and wave height.
The quad fin set up is very similar to the twin fin except it provides the board with more drive and speed while on the wave. The quad fin setup is becoming more common as it allows fast turns but also helps the rider gain more speed as they progress down the wave.The extra side fins that the quad fin setup features provides the board with more stabability when making fast turns. Twin fin setups are starting to be exchanged for quad fin setups when surfing in larger waves because of their increased stabability and speed.
