A surfboard's Quad Fin layout consists of 2 front fins and 2 smaller quad rear fins. It pretty much blends attributes of the twin fin and the thruster. That added down-the-line speed without the resistance/drag of the centre fin in a thruster, but with more hold and controlled manoeuvrability than the twin.
On smaller gutless days, having a quad fin surfboard with the rear fins closer to the rail and slightly further up, will really loosen the board up for you. This allows for quick manoeuvres and sliding the tail around as you need with ease. It also gives you that much more speed through the flats as there is no resistance of a trailing centre fin.
For the bigger, hollow days, the quads with rears place back a little and also close to the rail will provide extra speed and hold in the face of the wave. You can take higher lines on steeper waves with the extra hold of having two fins on the rail. Plus that extra speed, again due to no centre fin drag, comes in handy on those freight train barreling waves where there is not much room to turn anyway.
