Quad, big fins in the front or big fins at the back

Probably been done before......... But..... I was told when I got my fish the 'big fins go to the front when running it as a quad' but I reckon it goes better when I run them at the back. I suppose it doesn't matter really, and I can put the fins in any orientation I like, but one of my mates goes on and on about it I wish he would shut the fuck up! So which way do you run the big fins on your quad.

Hi Salt ,
mate im no expert or anything but i have a few quads and have been riding them for the last few years and its always the larger fins to the frnt and the small ones to the rear for me and they seem to go good that way , if you look at any purpose built quad fin sets that are purpose built that seems to be how they are designed . Hope this is of help
cheers

Cheers bishman, I might change them around and see how it goes. I'm sure there is a reason they design them that way. I love the speed of the quad, i get around sections i would never have made before.

Don't listen to em Salt, run them which ever way you like. Different fin configurations will obviously give your board different attributes. Maybe surfing with larger rear fins is a good configuration for your surfing. Typically larger front fins will give you more drive but larger rear fins will reduce the tail sliding too easily.

Search McKee or M4Quattro in google, this guys basically tried every configuration and position possible and documented it. Really just a shapers tool but some good info there for anyone wanting to know more about fins and how they work.

Julian Wilson often surfs with bigger fins at the back in his quads.

Interestingly I surfed my favourite quad as a thruster in perfect waves over and over again a few weeks ago and it didn't feel anywhere as nice as with the 4 fins in.

It was a lot more sticky, less drivey and just didn't feel right. Switched it back to the quad and it was perfect, loose off the top, super drivey and never slides out at all, holds well in steep critical faces due to it running into a pin tail.

This has the big fins at the front and the smaller ones towards the rear and If I switched that around I think it would surf more like it felt when surfing it as a thruster, ie loss in performance.

You'd probably enjoy riding a twinzer board. I've always been curious how they'd go.

I would like to try big rears on fishy boards. For a rounded pin fish ive been riding a bit lately, it really likes futures controllers on the bottom turn side and stretch quads on the cutback side.
Bottom turns are too loose with stretch on inside rail. Backhand or forehand.

Tried out stretch rears with big controller fronts last few days in some barrelling peaks around here.
The stretch rears have longer base than controller rears, but less height.
Felt really good fast and drivey backand in the tube. But hard to carve,cutback, snap etc.

Actually hit a rock yesterday and unsure if i should repair glass before riding it again.
Fibreglass mesh can be seen but only one crackthrough resin.

Feet near the front fins more drive feet near the rear, looser.especially fishy boards or thicker railed boards.

i change my set up around a bit' on more solid days i put the big fins in the back { infact started putting big fins front and back on ledgy waves} i normally ride 5'10 or 5'8 . Amazing what they can handle with big fin set up. :)
do get flack though from staunch crew who think its "incorrect"

groundswell nailed it with foot position though, no point if your back foots not in the in the right position.

Very interesting thread Salt, cool.

Like Carpetman has said try what ever you like, what ever suits your board and your style.
As Groundswell said about different fins front/back either toe side/heel side turns is an awesome thought line and development with your own surfing. Wicked mind concept GS, I like it :)
Cool shit fellas.

Thanks welly its been fun trying all sorts out.
Roger, i have lots of futures fins for sale in sydney including stretch quads, scimitar quads might be able to find a single for you but im in WA now, my brother could sort it if you want. Could post. Which side rear was it?

Suprised to read about big fins in back & smaller at front .i would think that unless the shape of board was designed for that setup it wouldnt work. I use futures fins & its not possible to change them from front to back . Udo are u sure julian wilson does that ? Considering his model fcs thruster has a smaller rear fin than sides ??

Hey camel do you still have that isonetric(?) Quad that i think you wre riding about 8 or 10 years ago? Didnt it have a squared wide tail or something and keel one side? Might have had "save a whale kill a goatboat" on it. Would love to have a look at it.

If you have a quad set of fins , you will notice the front fins are bigger and are only foiled on one side.

The back fins are smaller and have a 50/50 foil....normally the front fins are cambered out to 5-6 degrees , and depending on if the board is for small waves the Back fin is about 1-2degrees less...

if the board is for bigger waves the back fin is set at 1 degree......

just for interests sake when you buy a Quad/Tri 5 finbox set up.....the fin positions are all a compromise....if its a pure Quad,side fins are at 11 1/2 " ,where as a Tri is at 11....in other words by making it a 5 fin box system you compromise the performance of the shape....

Very good info mc . I read bob mc tavish saying that in surfmag 4 yrs ago just as i started my first of many 5 box future finned boards . Then i was led to believe it was ok becos i read SLater said it was . But im sure you are totally correct. Groundy yes the board was assymetric , shaped by me & fin set up designed by me . It had an offset single fin with cant plus three little bonzer fins . All in assymetric positions . Set for going left for tubes , very fast down line .

Oh groundy that kill a goatboat was on another board , it also had papamoa mafia written on it that was a bob davie six channell i think. Thats right remembered it said save the waves kill a goatboater or somthing similar . I lost that board along with 2 others by leaving them at denpasar airport . Along with all my luggage and heaps of amazing fins handfoils and assymetric foiled singley fins .bit of a horror loss , hope some one made good use of em

Been on quads /5's (pure quad with a stabiliser to make the same board a step-up) since 80/81 and always run big in front , however the last few boards I've made I have tried some adjustable 4WFS plugs.
Awesome for changing your toe and splay configs on the run , splay is via canted inserts and toe by 2 gru screws , absolutely awesome.

I made a miscalc on one of my rear fin lines , got distracted and didn't recheck before making mark , rushed off to glassers ..... board came back from glassing and I noticed I had toe issues on one rear fin , normally thats a non recovery cluster , but with these 4WFS fins, u just loosen 2 screws , a twist to the correct line , tighten and off you go ....

Agree with indo. I ride a high volume fish and it works heaps better with the large fins at the back.
Try both and go with what suits your board and surfing style, and the type of waves you ride.

I actually prefer big fins forward, small fins back...but i still think people shouldn't be limited by people saying how it should be or even what others take for gospel is best.

Luckily for me i use future fins so ya cant get your front n rears around the wrong way . But wat ya can do is swap them over from left to right . So the flat foil is outside and fin leans over towards the stringer . How bout that for freedom of choice of fins backwards sideways watever .

He instigated futures into oz...?

I put in 4 side fins from two Large thruster sets in my quad for a 4-6ft hollow beachy and it was friggin mental. Turning was a challenge, but the speed was next level.

I need more fins.... You can't have too many fins... Mmmm fins

Skwid do you think there would be much of a difference if you used rear fins rather than side fins whilst using larger thruster fins all round ??

A good tip if you want your quad to drive well and be superfast, is put your favorite side fins in the front and the same type or shape but one size smaller side fins in the rear..Example.. AM2 sides in the front and AM1 sides in the rear. This works especially well for bigger guys or guys who just want to fly at warp speed.
