CHANGING YOUR FINS = PERFORMANCE
3 fin Thruster (2+1) SUPS
The fins of the 2+1 or Thruster SUP take the rigid stability of a classic longboard fin being the (1), and fuses with the strength and drive of a Tri-fin which in short means combined ability for carving turns and providing control and drive off the (2) side fins, hence 2+1
Changing the size of the side fins will loosen the board in waves , but it is the center fin which can truly transform the boards stability and performance.A large Center fin will make the board stable in flat water but harder to turn in waves, beginner paddlers will appreciate this in flat water or conditions where there maybe wind or chop but getting stuck into waves and trying to turn your brand new 11ft SUP can be challenging to say the least.
The noserider fin is a big beast making turning the board more difficult, but its size anchors the tail so if running to the nose to get your first HANG 5 or 10 is the idea , then look no further you’ll have to try very hard to bust it out for a intentional 360!
