Future Fins Scimitar
The Future Fins Scimitar is a constant variable plane fin, based on a variable algorithm. Starting with Future Fins plain Vector foil, the fin twists from the base and then cants in. Future Fins does it on three different angles of attack giving the Future Fins Scimitar maximum water attachment. The Future Fins Scimitar is a highly refined design and smooth riding fin that holds through more of the turn. The Scimitar is a very lively fin, best for rail-to-rail surfing.
Future Fins Scimitar Fin Size:
Height: 4.52 in. 11.5 cm
Base: 4.37 in. 11.1 cm
Area: 15.39 in.² 99.29 cm²
Scimitar Trailer - Hatchet 450 Fin Size:
Height: 4.50 in. 11.4 cm
Base: 3.35 in. 8.5 cm
Area: 13.2 in.² 85.16 cm²
So, my next question is, what kind of board do you ride with these fins? A quad fish kinda thing? I would be looking for the FCS equivilant, as my plugs are not future.

When you refer to "fish fins", I assume you're talking about the Gephardt style, low ratio "retro fish" keel fins.
Interesting concept you have. I would normally say "yes" to the increased drive and speed the keel fins make. However, two factors could negate your theory.
1) The increased rocker, and particularly, the increased curve in the tail area of a quad fish (as opposed to a retro keel fish) could undo the usual benefits of the Geppy fins....MAYBE.
2) Does FCS even have a keel fin setup? I run LokBox on my quad, and there are Geppy style fins available for the LokBox. Never used 'em, tho.
I would only run Geppy's solo, with no leading or trailing fins.
I've also heard excellent things about the Scimitar fins in quad setups. Might be worth a try.

So, I know this angle doesn't show much, but here is my actual board, with the fin plugs, from above....
So yes, I was refering to the "keel" style fins. And yes, FCS makes quite a few styles of them. THe photo I posted above (the blue ones) are FCS keels.
As for the rocker, it is a pretty flat entry rocker and not too much rocker in the back, so it is a standard san diego fish style template with some tweeks for performance....
So, my general idea here is to have a 2 fin Keel setup, with 2 m2 trailer fins on the quad...
Im affraid of losing a ton of grip and drive if I go from 4 fins to a standard 2 keel fin setup. So, I am thinking I will get added grip through turns with the larger/wider front keel fins and normal foil trailors...

So, technically, my m4s are "taller" than a keel style, but there is a ton more surface area on the slightly shorter, much wider/longer keel styles. So, im wonder if the shorter, wider, more surface are kind of fin would take me in the right direction, or backwards as far as where I need this setup to go?

zach, it's a neat concept you've got, but my initial reaction was that you'll end up w/ a very stiff, tracky board. you're used to a thruster set up, so i think that if you want more hold, you should seek out a fin w/ more rake. i really like the merrick template.
\nalso, what material does that mckee set use? it looks like the crappy plastic (fcs calls it "glass flex", which is bs). that could be part of your problem as well. if you're a bigger guy or you exert a lot of force on the fins thru turns, you'll be over-loading those plastic fins, causing them to over-flex & wash out. a stiffer material could eliminate that issue.
\nfcs al merrick fin:
\nPerformance Core material and construction is designed to deliver the feeling of a traditional fibreglass fin with the added performance of reduced weight. The RTM (Resin Transfer Moulding) process produces a lightweight fin with remarkable flex, a smooth feel and an impressive aesthetic.
\n Base: 4.61" / 117mm
\n Depth: 4.70" / 119mm
\n Area: 15.63"² / 10083mm²
\n Foil: Flat
\nmaybe if you drop that in the front of your set up & keep the m-2 rears, you'll get the hold thru turns that you're looking for.
\ni also think that this quad set might work for you:

So, im running with a standard set of FCS foils for my quad fish. Although these fins perform well on the mushier, less steep sections like the cliffs, when it get to that low tide, at the beach break, Im still getting a little slide out on steeper turns.
If I use the standard FCS foil fins on the back, inside fins, and got 2 of the actual FISH style fins (The nice, fat wide ones). Do you think that setup would lose a little speed, but get more stable grip when you really bury the rail?
Im just thinking here. There are a ton of fins on craigslist, and I want to play around with it and get a tighter, locked in turning setup. These fins release well off the top and stuff, but they dont dig much on steep turns....
Any advice? Im a traditional thruster guy as ive previously stated... So im new to this quad stuff.
