Excellent, though commercial, article, but I gotta smile after > two decades of catching grief for sailing multifinned boards:
"They're too slow."
"They won't plane."
"Whaddaya need all that crap for?"
"Didn't ya hear? One good fin is all ya need."
"If you'd earn how to SAIL, you wouldn't need training wheels."
"I tried a Bonzer once. What's the point?"

Very interesting post

I had a JP Single Thruster 83L 2011. The fins set were 2x10cm + 1x20cm. The board had an early planing, and an easy surf. The problem was when the wind blew up, and you were overpowered...
Now I have a Naish wave trifin 80L 2012. The fins set are 2x10 + 1x16,5cm. The board last more to get planing than the JP, but it works better overpowered. The surf is also easy, and more radical than the JP. I'm very glad with this board. In fact, I have bought the same model in 87L (year 2011) It works as well as the 80L

This two boards are very different but not only about the fins set, also about the shapes (botton shape, tail,etc)

This is my experience in thruster/trifin boards Very Happy

Great guide for the 3 finned boards,

you can change the feel of the board, ie its character by using different size/shape fins, but not its characteristic, which are also defined by bottom shape , rocker rails, and how many cheeseburgers you had last night .

BPF have posed the fin area POSTED as well as length, they both should be considered in comparison when picking your sets. The BPFs are very efficient for the length, top of the shelve in all respects.

Many variables , weight of the sailor, experience, sea state , wind strength.

some terms transpose from surfing to windsurfing, thruster being one that gets lost in the translation. In surf terms a thruster will have the 3 fins very similar in size, 15, 13 13, not 17.5 and 12.5 12.5 which would be a 2+1

or never wrong a tri fin. Sorry its rather like when is a quad not a quad but a twinster.

This new guide was finished yesterday so now I can share, this (noncommercial) tuning guide gives you a few pointers and things to consider when positioning your three fin / thruster set up so that you can adapt your equipment to your style, weight, sailing conditions etc.;

Hope it is useful and remember we are here for questions.

So what it amounts to is that multi-fin boards increase exponentially the chances of getting the board, fin, and sail balance totally wrong, and since one can not demo fins, ya better have deep pockets,my friend, if you are going down this road.

Another argument for kiting??
