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 |

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. _________________ K4 fins

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.;
http://www.blackprojectfins.com/thruster-set-up-guide-for-maximum-performance-and-range-of-use/
Hope it is useful and remember we are here for questions. |

For most uses this is in my opinion too much fin for this board. The the JP 83 Thruster we are suggesting 11.5 fronts with between 15.5 and 17.5 rear fin. Alternatively it could be ridden with a 22cm single fin. So 20 + 2 x10 is massive!
More set up suggestions for JP as well as Starboard, Fanatic & Mistral can be found here - http://www.blackprojectfins.com/which-black-project-fin-should-you-choose-for-your-board/
Hope that helps |

Thanks for your comments, I totally agree, check out the Tuning Guide too, this is more of a general discussion. Equipment has come a long way and now that boards are wider and shorter the multi-fin options make more sense, that being said there are a number of riders; Mark Angulo, Kevin Pritchard, Levi Siver and more who RIP on single fins, although they have multi-fins boards too.
We do need to help riders get the most out of their boards and hence why we are trying to write more articles and set-up guides so that everyone is fully informed.
Thanks |

Well, in fact, the JP THRUSTER 83L 2014 brings even a bigger central fin (21cm):
http://jp-australia.com/2014/es/products/boards/single-thruster/
In any case, it depends on the use of the board. In my opinion, the JP THRUSTER is a wave board for all conditions. A concept between a freewave board, and a "radical" wave board. As well, what U2U2U2 says about the shape is the most important. I bought a 18cm central fin for the JP, but the board works more or less the same. For that reason, I changed it for the Naish wave 80l |

Probably the most accurate point being made on this thread so far.
Fins will reflect your attitude, and frame of mind and/or body. |

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??
