Talking fins ...big sides ...

Just mucking around with fins again ...brought 2 sets of shapers...one set with five fins ,other with 4 ,a bargain at $100 a set ...the five set .carbon flare ...had bigger side fins than my original Naish fins .8 instead of 7. 'S .the rear fin wais small compared to the 6.5 Naish rear fin .but put them in and headed out ,I thought I was going to be spinning out with such a small rear fin ...but the opposite ....so I now feel the stiffness of the board is very much decided on what side fins are put on .I did paddle in and push the rear fin up ,and got my looseness back again ...jus cruising ,the fins felt the same ,but when you started turning and throwing the board around ,after market fin really do make a huge difference ,more speed ,and just a nice feel with the slightly flex of the carbon over glass fins .

With the bigger sides I did manage to make it around a few sections ,over the smaller original side fins .and did liven up on the bigger waves .

The second set to try tomorrow will be the super light honey comb quads .core - lite.

any experience and ideas on combos are welcome .with your past experiences .I'm a bit of a newbie at the after market
fins ,but so far are liking the full set change ...before I would only change 2 .the very small rear really improves the nose snapping back around .

It's always fun to try different fins to change things up.

A few years ago, I was trying to loosen up a few boards, so I threw in some really long based, big sidebites and ran a few boards as twin fins.
They had surprising drive and bite in some steep head high waves... but still really made the boards loose and snappy.
I never noticed a need for a 3rd center fin. I abandoned that experiment when I got into more performance boards.

The fins were all Futures, so the boxes could handle the large area of the fins.
All of my boards now, run FCS boxes, so I haven't tried the big twins lately.

Nice twin supthecreek....also a pin tail be fun in smaller waves ..

colas..yeah the big 8's I have they are super thin too and very flexy .but it's good with the small rear .
i do like the way you can ride the wave high .and it still feels pretty loose ...because I has the x32 Hokua .it is
wide and it does work well.with the big sides...
It seems funny how I'm using the same fins as my surfboard ( that doesn't get used anymore)....yet riding a bigger board....?
i guess it is a lot to do with your weight .

but wow ...the original fins will be wall hangers from now on .

thanks for the cool vids.

I love a bit of fin porn. I'm a big fan of a smaller rear fin in a thruster setup. I find it really loose but with just enough bite to stop you spinning out on hard cutbacks. I've also used a double zigfin for the rear fin which works well (and even double zigfins as the rears in a set of quads). I don't really bother when it gets big but generally if I do go out I replace the rear fin with a standard thruster fin for bigger waves or the board is just too loose.

I like the idea of trying c-drives but they don't appear to do futures which is a shame.

Yes Jhon, Colas;

H3, H2 and Beachley FCS fins models works good on shortSUP also C-Drive do it too. As well the TC red line ... all those fins templates are wide base and shallow tips or fin templates have narrow tip like C-Drive or TC ones. All those fins template have a common denominator which is to be compact and reactive .

To my opinion the reason why they work better on wide tail board and therefore SUPboard is the fact that the distance between your back foot and side fin has to be the shorter as possible.

So as compact but still functional as possible the side fin have to provide efficiency to dig the rail and board planning aera with the less back foot pressure as possible.

Also advantage of those fin systems of shallow fin is to have less drag so getting faster.

Last input is about fin toe of all these fins H2, NEXUS, C-Drive, TC: As SUP tail board are wide, no need to have toe get the board loose and maneuverable. I already demo on my own board that zero toe give more drive and stay very loose.
