Another reason you would find the board not coming around quickly is because of the rail going into the tail. Round tails are know for more drawn out turns because the rail going into the tail is straighter.


Nope, it doesn't reduce drag nor does it increase speed, sorry. All modern side fins are foiled, curved on the outside flat or slightly foiled on the inside. The foil creates lift, but what we mean by lift is not that it lifts the board, far from it, the lift is sideways, so when you turn you are being helped by the fin to turn. More help turning means less help going straight, so in essence you give up glide for turning ability.

But, anyway, nothing beats good form, so keep at it.

Ha ha hah aha you need to do a bit of reading into Future fins my friend. I was testing the Vector Foils over 5 years ago and it was all about speed. Here is a bit of knowledge from Future themselves

VECTOR V.1
For increased speed & thrust - A unique patented Vector Foil creates lift in the same way an airplane does. Curved on both sides - as opposed to a Traditional Foil with a flat inner face, the extra lift creates projection and increases water attachment which also increases drive and speed.

As I originally posted, I get into arguments about this. I know what I've read, but I'm talking about buying a set, trying them, buying another, trying them, so on and so forth. By trial and error, not by reading, I liked the F4's better, they released into the wave better than the FEA450 or the FAM2's, though those where looser. The F5's had awesome glide but much less performance.

Anyway, looks like the guy figured other reasons why performance was off. No biggie.

Mate all good. I'm in the same camp when it comes to trial and error. I have every fin in the Future range (being a shaper it's my job too know which one works with what) and have the bad habit of changing fins every single surf. I really should go back to glassed ons :D

by the way, in defence of Future fins (though I prefer FCS), a buddy tells me that when he bought a custom Rusty they told him at the shop that they use Futures only because with FCS fins there is a slight (very slight) gap between the fin and the board, which cuases drag since water gets in there, whereas futures there is no gap since the entire fins goes into the board. Anyway, not sure if it's scientific evinence of this or it's someone's factoidal fabrication, but thought I should mention it.

I still prefer FCS, I think mostly cause I tried almost all of them and have them dialed for my boards.

Yes FCS have the problem of being seated with 2 separate tabs which means they will never sit flush with the board because of the contours in your board. If the boards bottom was dead flat they would sit flush, but find me a board that has a dead flat bottom.

The bonus of Futures is that the whole base sits inside your board and spreads the load over the whole section of the box giving a more instant feedback to the rider. And preventing the fin base moving and rolling like you get with FSC which can give you that lag in response (I know people who like that)

Also the fact Future boxes sit under the glass makes them stronger. Although FCS released the Fusion box to compete on that level, but they totally suck to install and many shapers aren't using them. There is a new brand of boxes from Hawaii that are almost the same as Futures but take FCS which are much better.

All that said I don't care what anyone uses, I don't make boards with FCS at all, only if someone really really needs them :D

If you can get glassed on fins next time do it. It will make you learn the board better and make you a better rider by adapting, which is what surfing is all about in my book.

I guess the rtm f4 fins in clear has been on backorder a long time. The shop I ordered from talked to future yesterday about them. Now they are just offering blue or smoked at the moment fyi if your looking for the clear ones i posted unless you can find some leftover stock in a surf shop somewhere.

well what ive found is....flex = good lol a fin that bends with the board to match the turn is what works best....for me...ive been switching up on my squash tail 6'2 and fcs g5s also Fg3s . Fg3s are very stiff and are good for big drawn out turns on bigger waves that bend the fin, the g5's work better with quick snaps and shorter shifty turns ive ordered the natural VF4's to try out these FEA 450 i have are stiff as F*** lol so i dont know ill let you guys know what the vf4's are like
