OK, so have made my mind up to go for the C-drive fins in my 9'5 Speeed. I would be interested to hear what others think would be the best size to go for my 105kg body weight and to be used in shoulder to head high waves?

Thanks for the ideas!!

I think the confusion regarding smaller trailers comes from the Non Troy approved fins from Pacific
Vibrations..

They do have a smaller trailer available. But no BIG Twins to use it with..

Made contact with Troy,
There is a trailer.... 2 sizes smaller than Grom coming with
new Big Twins..... end of November . Fcs n Futures. Small batch.

Whose interested ? and for what board ?

Hi Shi

The medium Cdrives should work well with an 9'5" Speeed. The channels on the Speeed will add some hold and drive. There is not a big difference in surface area between the large and medium Cdrive fins (I have all three sets and when my wife looked at them she thought I was nuts because they all looked the same!). So even if you went for the large set you wouldn't be too far off. I wouldn't worry too much choosing between the medium and large. Either would be great. Have fun. These really are a special fin that work great with SUPs.

Cheers

Awesome Bob, thank you very much for your feedback, really appreciate it!!

I haven't been supping for a while now, back surfing again and back seems OK (touch wood), but I saw video recently of me riding my 8'5 x 29" 2013 carbon Starby (106L) in the Ments last year with c-drives and for that board I use XL fronts and tail/centre. But what I have done is get a local bloke (with a hand in a well-known fin company) to cut away the base which sits in the box and reset the pin so that the tail fin can be positioned much further back (I've got two fins done - one about 1" cut and the other 1 3/4"). I've found this dramatically increases the hold and drive, without much difference in looseness. It's required a slight shaving off of the bottom edge of the rear of the fin base to get it out of the box again, but only 1-2mm. It still makes a bit of a gap which is exacerbated by the tail rocker. I've found the turbulence from the gap is well and truly offset by the increased control from the more rear-ward position of the fin.

I also use c-drives in some of my shortboards and they're still fantastic.

Speeed was noticeably looser and could snap tighter turns with the small C Drives.

I will try the small trailer soon.

Hi Tang

very interesting modification of a fin. Could you post a couple of pictures?

cheers

Sticking a regular FCS c-drive into a longboard adapter gets you a little more overhang than the center fin version, just under an inch for my Size L.

BTW.... there is a massive difference between using them in Quad VS Thruster set up. I use Quad on mine. I tried the thruster set up today. Like I had a brick under the Board.

I have a quad setup - 8'11" 32" blue plant custom. 88 kilos on 140 litres board and love it! How do u set up the quad/ is there 4 "c drives" or two only mixed with what? Help! Thanks Steve

4 C-drives. In Thruster use 3 C-Drives. Max performance comes from all fins being C-Drive

I visited this thread again yesterday, and it got me thinking on my way home after my last day on shift. It's a long drive.
I knew the wind was swinging around, and would push up a few little beachies. Not much, but just enough.
Should I dust off the C Drives and try them on the hipster twin longy?
Why the f not.


I'd forgotten how squirty and how much fun these bad boys were.
Made for a great little sesh.

How do you find them in the hipster?

Can anyone give me a quick run down on c drives vs quobba?

C drive would be suit to waves with a little bit less punch?

I have both......for me the you just cannot compare the Quobba's - C-Drives are just awesome in all conditions. I just converted a prone surfing mate to a C-Driver thruster set up and he has also used my Quobba's - he is now a C-Drive convert.

I'll Have to order a set for my hipster mini longboard and see how they go as a twin with the standard small trailer fin

For maximum C-Drive impact - run all fins in C-Drive
how these fins did not set the surfing world on fire when Troy first released them many years ago baffles me - but when you have 2 gorillas controlling the global fin market...

To be honest, 99% of prone surfers are very conservative and know nothing about fins, they just choose on the color or what the pros ride.

A C-Drive model was even in the official FCS line at the time...
