I have been scouring the resources for info on quads. I’m fine with placements, but have hardly found anything on cant. What cant should I set my fins at? 4 front 0 back? 8 front 6 back?
The board is a 5’10 fish, 16 1/2" nose, 21 1/2" widepoint (2 inches ahead of center) 17 1/4" tail, 12" pins, about 2 3/4 thick. I will be using probox.
I’ve been doing 6 front, 4 back. But I’m sure Larry will come along and tell you that’s all wrong. Haven’t had any of my guys asking to play around with the set up.
And I've got some FCS TC Aqualine fins the front, which have 6* preset off the tabs, plus the plugs set at 6*, giving 12* on the front! Works really well. Quicker rail to rail and much tighter surfiing in bowly pockets, but a little slower down the line.
I've just switched to Probox now I've felt the difference adjusting cant can make.
All my Quad Fish are set up per the Kensurf and ProBoxLarry method.....Fins parallel , Fins 1" to 1 1/2" apart , 8 degrees front, 6 degrees rear...Big fin forward...With ProBox you can change the cant so you might have to do some test drives....
I spent $100.00 in fins just so my "test rider" could tell me what I already knew from reading Swaylock's...Ha Ha...
Been down this road . . . I reckon 6º and generally 4º is good.
The closer the back fins are to the front fins the closer they should be to 6º.
The further back (and towards the centre of the board) the rear fins are, the less cant they should have (Just as with as toe-in). Like if the rear fins touched in the centre of the board they would have 0º cant. To put it another way, the cant of the rear fins is (depending on preference for placement) in between the 6º of the front fins and 0º cant of the position where a rear thruster fin would be.
Depending on the proximity of the edge of the concave to the rail, and fin position "in from the rail", a concave may pull your cant towards the stringer. Therefore reducing your actual cant by a degree or 2... possibly.
Vee tails already provide the fins some degree of cant relative to the flat. So a 0 degree on a Vee tail is actually 1-2 degrees canted. Of course the amount of cant depends on the amount of Vee.
I've run just about every cant combo with ProBox in my quads (even 8 and 0 - why not try?) and settled on 6 up front and 4 rear for East Coast and Caribbean waves. One quad is a double to single concave and the other is single to double - 6 + 4 in both of 'em.
there’s no right or wrong. Fin size will make a difference in what cant works best too. Another option for a 5’10" flat bottom fish is 0 degree cant, keel fins and a TTF (tiny trailer fin).
You never know what you’re going to like until you try it.
So 6 and 4 is most preferred, despite Larry reccomending 8 and 6. How come?
Thanks Brian. So, if I'm running a flat bottom 6 and 4 is still fine? This board is for east coast/ great lake / river waves.
And Monty. I like your explanation. Makes sense!

Hi freshwatersurf, I perfer 8 and 6 degree because of the beach break I surf at is a short wave, with not enough shoulder time and I am riding back side most of the time. Most common is 6 and 4 when you are surfing front side with more shoulder on the wave. If 6 and 4 give you a hard time backside then switch the fronts to 8 degree to losen up the board and leave the back at 4 degree. Running a flat bottom you might be 8 and 6 though. Brain also made a good point with bottom contours. Hope this helps to determine your cants. Remember as I explained the conditions of the break will also help in the cant preference of the day. Have a happy 4th my friend.
Also Happy 4th to all my Swaylockians friends, be safe.
