How big is that thing? The rears looked like they’re toed in pretty far, maybe it’s just cant or the camera thats messing with my eyes.
i ask because *i've heard* that on rail finned quads, the side fins should be flat inside foil and that with the McKee setup, the rear fins should be more symetrically foiled...
caribbean, how does your buddy's board go? have you ridden it? if it's good, then go with that... FWIW, i think that adjustable finboxes are key for quads. way more so than with a thruster. everybody i've talked to has had to dial in their quads whether it be by changing fins or moving the placements or changing cant, etc...
EDIT: except for the guys that ride Griffin's boards... the concensus is that he pretty much has his designs dialed in regards to fin and placement.
Hi Chrisp, my friend told me that board is a copy of a rusty dwart, 6.0 x 21 x 2 13/16 but with different rear fin placement because he says the original dwart comes with the rear fins to close each other , I think this is the big discussion here! I have not tested the board because no waves here, I’m just curious because there is a big debate between the placement of the rear fins in quads, I’m going to buy my board and the last decision is the rear fin placement or go with a multiple set up to be able to put the fins on rail and the other setup like the mckee.
Thanks
those dims sound like a fun board... what kind of boxes are you going with?

Thanks JhonnyK3 and Chrisp for the replys, Look at the next picture, as JhonnyK3 said the last picture looked very confusing because of the camera angle of view, I put the template on transparency so you will have a better idea of the placement and measures, (it's not very exact but I think it works...) So the rear fins placement are not Mkee style and nor Rusty Style, so , I think if I want multiple setups I will choose first as the rear fins are (black lines), and for second the rusty setup, because the black marks and the mkee marks (blue lines) are close and maybe not worth the difference. My idea is, on small days (3-5ft) use the black lines setup, and for days like overhead or barrels choose the Rusty setup. Please let me know if Im wrong, Im not an expert surfer, Im from beginner to intermediate,
Thanks a lot.

Caribbean, all the black fins are set 1-1/8" off the rail based on a 6’-6" with a 15-1/2" tail. The fronts were taken from McKees specs based on that 6-6 (11-5/16" fronts) so yours will be a little further back, not much though. The rears are set at 1/2 the distance of the fronts.
I measured up my buddys Dwart and have the dims right in front of me. It’s a 6’-0" with a 15-3/4" tail. The fronts are at 11-1/8" from tail and 1-5/8" off rail (measured from the corner of that first wing). Once it steps back down it’s closer to 1-1/8" if that makes sense. Measuring around those wings kinda throws you off. The rears are 4-1/2" from tail and 2" off the rail (like the red fins in the pic). Toe in was 1/4" front, 1/8" rear. To make you more nuts and if you want to cram another box in there it’s 3-3/8" to make it a thruster.
Looks like you’re close with that pic. Hope this helps.
thanks Jhonnyk3, what kind of foils has the dwart of yout friend on the rear fins?
were they flat insides?
thanks
The fronts are traditional flat insides and the rears are 50/50 symmetrical foil. They are one of those Futures quad sets so the rears are all 50/50 no cant (I think). 4.5" tall fronts, 3.75" rears. Like others said the symmetrical rear foils will work best with the Rusty or McKee setup, not so good out on the rail.
As you can see, a lot is personal preference:
Generally…
Closer to rail (both pairs) more leverage aka drive to the point of sticky
Less sticky if pairs are grouped tighter and/or rear pair moved toward center in from rail)
More cant more toe = looser… Less= drivier
Rear pair flat foiled = drivier or eliptical foil = looser or 2 side foil = loosest
McKee’s set up will feel closer to a thruster than ones close to the rail. But w/more drive.
McKee has researched this more than anyone on this planet. Probably Mars & Venus too.
Riding a quad takes adjusting, anyone that doesn’t like quivers or is an old fart wed to one way of riding should just stick on their log, single fin, old beat up MR twinny, Bonza, or sponge…
For the rest: open yer mind yur ass will follow… and quicker than a tri.
Good post Deadshaper, I agree.
I think he’s going with 6 different boxes/plugs. Makes my head hurt thinking of all the various setups! Very versitile though.
I still stand by what McDing pointed out. The fins are too far apart, fore/aft, for optimum flow. Once the fins are more than an 1 3/8" apart, the interaction starts to diminish as does the speed.
Something I’ve thought a lot about - and was hipped to by Robin M. - is the amount of tail rocker. To a point, more will lead to “sharper” turning, and with out the interference drag and inherent “switch” in flow between the side and center fin on a tri, this will help with the “snappy” feeling.
Then again - This is like the bulb fin thread… What feels/works good for you, is good for you. Does it matter why it works?

Well Put, LOL!!!!
Ok, the pics are in the wrong order, but here goes. This board is my "good wave" board, which for me is hollow 3-4' beachies. I got it with a quad setup similar to Mckee quad. I had a few good surfs on it, but mostly felt like it was too stiff. I had until that point been surfing a twin keel for a few years. I eventually found the best fin setup was the last pic, with little orange one tab fins ( they were superchargers on my twin keel ), fast and loose as hell, but controllable. I thought that if i had another fin set, closer to the front fin, and closer to the rail, it would suit "my" surfing style ( or lack thereof ).
Had it done for months but i still havent got this board wet yet, so no ride report yet. I hopt to change that very soon!!.
Hope it helps in some small way. I think how you surf makes a difference. I think because of the time i spent on a twin keel ( happy days indeed! ), i surf more forward on the board, as in, i very rarely get my back foot way back on the tail ( my midlength excepted ), so it suits my natural standing position on the board.
Cheers, let us know how you go.
That boards going to be too slow Beerfan, you need more fin plugs

I like how you think Beerfan (-: Mahalo,Larry
