Gong Perv 12'6 -> when is a 2+1 setup useful?

[AndiHL]

Hi folks,

as already mentioned in the subject of this post, I have a (SUP-surf-newbie) question:
When is a 2+1 setup useful on my 12'6 board?
Will the outer fin help turning the board, or will they give more grip but prevent it from turning?
I have here just mushy onshore waves and I'm quite unsure about the right fin setup.
And if it is worth to buy a new fin set.

Cheers
Andi

The side bites help the board turn and be more manueverable than a single fin. They also provide more grip but that is secondary.

Fin setup could change the feel of the board completely, for better or for worse. Best if you could borrow a set and try before you buy.

The Gong Perv works very well with a 2+1 setup, and is massively better for surf or downwind. I use a 7.5" centre fin in mine. The side bites add drive, directionality, and a certain amount of extra stability. So unless you are just paddling distance
, especially in flat water, I'd recommend using a 2+1 setup.  In the real world the extra drag of the side bites is usually outweighed by increased tracking and control.
