Single fins are fast in a straight line, but don't have the drive out of a cranked turn that multi fin designs do.
They do have excellent hold & stability though.
The main reason being that a single fin is in the water nearly all the time.
Single fin surfers tend to be flowing & carving, rather than hack & slashers.
With Twin fins, in a good turn, one fin can break free of the water & the other one allows you to drive out of the turn.
Anyone who's surfed a twin knows the amazing "Squirt" of speed you get out of a turn that you put alot of energy into.
Unfortunately Twins can be a bit skittery and have a tendancy skip or slide out when you put too much into a turn.
Also Twins can be slower in a straight line as the fins are *generally angled or 'toed' in towards the nose and therefore offer more straight line resistance.
Quads aim reduce the skitteryness of Twin fins , while keeping their best attributes.
Personally i think they are very difficult to get right. I've surfed some great quads & some real dogs (mostly dogs tho!).
Thrusters are an attempt to get the best of both single & twin fins in one design.
There were earlier 3 fin designs, but In the late 70's/Early 80's Simon Anderson created the Thruster.
He won The Bells '81 Comp in big meaty surf on a thruster he made & the rest is history.
It has been the most popular fin setup in the last 30 years.
Of course there's lot's of other designs out there, Twinzers, Bonzers etc.
The best way of deciding what's best for you, and your own style, is to try as many boards as possible.
