Hi All ,
after a bit of your vast wisdom here , got myself a tiny 5'8 fish for small mushy waves , in 78 kgs and currently have fcs g'3 s in it but find them to lack drive and speed anyone have any suggestions on what would be more suitable fins for speed / drive in small waves , old school fcs plugs in the board tri fin .

Does anyone have any experience/ thoughts on Scarfini fins? I have never tried them but am interested to know if they are any good?

Sexy Quad set from long time ago

Caml if youre out there - you mentioned a long while back about 4wfs and the fins bases possibly being a weak spot
Hers some of Jeds solid glass ones

Hastoes Sunday, 24 Jan 2021 at 05:46 pm new

udo, what size do you reckon for a quad set up in C-Drives? Normally I ride L. But watched noel do a review on em, the boys recommended he should've tried the mediums. I've a fluctuating weight issue ranging from 86-90 kgs

udo Sunday, 24 Jan 2021 at 06:16 pm new

Medium i reckon -
Never used to be a problem to swap over to M with Troy if Large were to stiff.

https://www.surfnvs.com/products/c-drive-thrusters-apex
Large is a big fin for Noel - Brutus is your man here him and RcJ are c-drive specialists - 2-60ft.

brutus Sunday, 24 Jan 2021 at 06:18 pm new

if you use C-drives , get the smallest .....S on the sides , XS rear quads.....that's what we use......we are actually wondering if even smaller would be better.....Naked Viking /USA....

Patrick Sunday, 24 Jan 2021 at 07:18 pm new

Hi Brutus. What size waves is that for?
Do you suggest going smaller in a thruster set up too?

Hastoes Sunday, 24 Jan 2021 at 07:45 pm new

Cheers fellas, FYI waves I’d normally be riding 2-6 ft , so y’all still reckon small front and extra small in the back ?

brutus Monday, 25 Jan 2021 at 07:22 am new

yeah RCJ and I use small thruster size, and we are both 90kgs....same with gun Quads, Noah Johnson who is 5' 3 60 kgs.......uses XS on all his guns from 8 0 > 10 ' 6".....plenty of drive with the long fin base.....
I just realized that the sizes we use are for my boards , where I have always used smaller fins because of the edges and concaves , giving you drive and lift so that's why us "Chunky Monkeys" can ride very small fins....less drag/more speed!

brutus Monday, 25 Jan 2021 at 07:23 am new

yep use small and xs.....if you can't get the drive , it's probably in the design of your surfboard!

Patrick Monday, 25 Jan 2021 at 04:47 pm new

Thanks Brutus.

Hastoes Monday, 25 Jan 2021 at 06:28 pm new

Reverse foiled fins ?

stunet Monday, 24 May 2021 at 12:23 pm new

"Reverse foiled fins?"

A question mark is my response too, Udo.

Water can't be compressed - which quashes the fanciful yet enduring Bonzer theory about the Venturi Effect - so how would these ride?

I expect they'd cause drag, slowing the board down, or perhaps the drag might cause the board to lift, which would temporarily reduce drag and increase speed.

Flex Memory Shelf Life of Fins...?

Hastoes Sunday, 29 Aug 2021 at 12:37 pm new

Have been using Medium C-drives (quads) for about 8 months. Best fins I,ve ever used. This week has been a different experience though with this current ballsy swell. Was driving nicely off the bottom turn producing a shit ton of speed but mid face and top turn slid out. Thought id busted out the fin box or something . This happened on most of the waves today. Solid 4-5ft but with more energy in the water than normal.

Hastoes Sunday, 29 Aug 2021 at 12:50 pm new

Any one else had this issue? if so what was a solution ? Any ideas out there .

udo Monday, 30 Aug 2021 at 03:20 pm new

Brutus ....what you reckon ?

Hi Hastoes , what dimension board are you riding and what weight are you?

You could be experiencing too much fin, which means, when more pressure/speed is applied to the fin , your weight /board dimensions can't control all the pressure so the fin lifts out of the water.
C-Drives have such a longer base than a normal fin.....even when I was at 95kg's I still used small c-drives....but my hull designs give a loft of lift ( concaves) and drive from very hard edges....
In big guns we have always used smaller fins as big fins feel like they are spinning out , when in actual fact the fin lifts out of the water.....smallest gun fins ever on AB's channel bottoms....hope this helps....send me dims and weight and will be a lot more precise on fin size.
