Bought a pair as side fins for my starboard 9'1"x29" pro.
The look serious but I know that doesnt mean anything, I wanted to loosen it up a bit and make an improvement on the stock rubbish.
Also bought a FCS longboard series 7" center. Will report back after I have used the setup.
Hey mate,
I use to ride a Naish Hokua 9"3.
I used a set of H2 Mediums in the board.
i started with using 2 in the front and the standard fin in the back but found that (with the use of a FCS>US FIN BOX convertor) the board worked way better with the full thruster set.
I found because of the huge side cant, the tail gained heaps more lift which got the board moving quicker.
It also held in nice when surfed off the tail, because of the side cant.
good fin, enjoy.
the FCS adaptor is the best piece of equipment i ever bought.
goto your local shop and try as many fins as you can,
they make a **** load of difference
Be careful underfinning a starby 9fter - IMO they handle anything down to about 6 1/2 inches as a centre but anything smaller they just lose all their drive and get really doughy and slow. I think a really good setup for starbys around 9ft is something around 6.5 to 7.0 as a centre and - say from M5 ish to GAM ish
sides.
On my 9ft starby I run a 6.5 centre (a fair way back from centre) and GAM sides and its just amazing and hands down the best fin setup I have ever tried on the board or similar sized starboard.
Sorry to get off track about H2s - only thing that would worry me about H2s is that historically they are a fragile fin so be careful with them in the shorey and I would be interested to hear how they would hold up in a sup in bigger surf or on heavy turns. They should actually surf very well in a sup you would think though and maybe pull the board onto rail quicker when transitioning from rail to rail in turns due to their exaggerated cant.
They did seem a bit fragile when i was installing them,
I tried them today, and only managed to catch one wave, they just werent quite peaking enough to catch,
on the one i did catch it seemed a whole lot looser and quicker from rail to rail but it really was difficult to judge on just one wave,
Im using the H2 large sides and a 7'' center. seems to paddle ok still,
Marco and Lummers are trying some different fin selections on their Starboards.
From what Marco was saying he is going to try using a centre fin the same size as the side fins.
There is a method to this madness but maybe they could shed some light on what they are trying?
ive found for responsive rail to rail riding a big centre fin, is alot more locked in a tracky.
if you want a looser/free-er ride put one the same or smaller in the back.
my basic theroy is;
small mush = quad.
clean semi fast = thruster all the same size.
overhead survival = thruster big center set all the way back.
a good old PC7 work well in the back too.
Ok after a few uses with the H2's I'm pretty happy.
finally managed to get them on a decent sized waved today ( shoulder highs ) and found them a good improvement on the original ones,
Rail to rail was smooth and predicatable, they didnt try and throw me off.
i think i need a better center, as when it picks up speed i can hear the plastic center starting to humm and i feel it making drag. maybe an extra large H2 with an FCS to US box adapter.
straight line paddling has become harder as expected, but i dont have to paddle far to the waves so its all good.
Love it!!!!
was looking at getting a set of these or the h3 nexus fins,i think thed go good, riding thrusters isn't really that new on sups people have been doin it for a while, i personally ride a set of kelly slater 2.1 fins and love em, had em out in surf up to about 6 foot, cant wait to get em in something bigger

Wasnt trying to be original with the thruster setup mate, just wanted to try something different and it paid off in my opinion.
Going to invest in a better center after chrissy and see how that goes!
Fingers crossed for some half decent swell...
it doesn't matter if its the exact H2 fin, i think its more the side rake on the fin.
I used some stock North kiteboard fins on my SUP (they have mega side rake) and they felt very similar.
Its all about the fin having maximum hold when on edge.
try the Kinetic Egans too, there pretty fun fins.
enjoy, keep us posted on your findings.
p.s (i tryed the FCS 3D tail fin, its a C U Next Tuesday, dont bother)
Could be the H2's that are humming, I will try my old center in it again, its pretty chewed up though, I might be able to revive it.
Not many days with swell and no wind coming up.
Will keep you all posted 
I use them quite a lot. As quad rears like on this one, as sides on a longer board with a 7".
BTW, this set up below is amazing!
The H2's are a brittle fin , I've cracked 2 sets on my short board , just be careful when your board hits the beach any side ways pressure in the sand will crack them.Personally I think the cant is too much for a sup especially if you have V in the bottom plus they are pretty small. They may feel OK but you are probably missing out on drive.IMHO.
Agree with Flecth on the 3D waste of time and watch the FSC adaptor they tend to drop fins I drill a small hole through the adaptor and the fin and put in a small pin to stop this.
Some of the early H2's were brittle in the tabs.
Contrary to what Rob says above I have found the added cant on the H2's to be particularly suited to SUP due to the longer drawn out turns off the bottom and also the high pressures involved in holding a wide tail high on the face. The cant angle is designed to remain at a more vertical angle longer with the board on rail, similar to a canting keel on a yacht as a point of reference.
Regarding drive, the board above has MRTFX fronts and H2 large sides in the rears. This is a very drivey set up and much drivier than most fin set ups I have seen. A lot of people use shortboard fins which are way too small for the rail thickness and tail width of a SUP.
