I have read some mention here of this set up - two fins in a row, and I am assuming it was sort of like a single fin set up.
Here is my question: (Back ground info: I made a think, 3" w/2" tail, wide, 24" w/16" tail, tri, board for small waves - and I liked it enough to try and push it into bigger/heavier waves.) I am going to put a second box in in front of the center box - Any suggestions on how far apart the fins should be?
Thanks - TaylorO
A good starting point is to position the trailing edge of both fins at the same points as a three fin you like, ie; 3" and 11" from tail.
Then start adjusting away till you find the fin positions you like for the waves you like.
You’re going to have fun.
the ones i’ve seen were smack-dab together, as claose as the bases would allow them to be…
Thanks for the replies you guys.
Wild - I’m not sure if that split would be good, as I am planning on leaving the side fins in, (Then again, maybe the 3 in line would be good too… so many options!) and the RedX boxes allow for only so much movement… Given Matt’s response, which I thought I had seen here once upon a time, maybe I’ll try 3 boxes in a row… Ha!
Seriously - and I have thought, been advised, about cuttting and gluing the boxes so as to make a long box for my RedX fins.
(TomD - If you read this, do you guys make the “twisted” side fins yet?)
Anyway - I’ll let you know how it goes, and someday, when Dale S. is feeling up to it (Ps. He can still use our money-love.) I’ll have him get the pics going.
…better to put the trailer behind , not in front of the main fin
I surfed about 3 years with this set up (around 1996 or so)
in a 6 3 x 18 or 18 1/4
with not too much tail area and lot of tail rocker
excellent for toobs or steeper beachbreaks

this is telling you that you can put your fins almost anywhere, when we were kids a friend had one up the nose for tuberiding…so you may decide the effect your looking for…a certain turn or position in the wave…great…possiblbly think of putting a fin where you want it to drive…im currently working in this area no measurements just putting the fins where i need them…up back and close to the rail and all different sizes…towed and untowed…or detowed or not towed…opposite to towed in…what i mean is keep experimenting…sounds like you will have something similar to a single…would be interesting.
Back in 77 there was a surf shop in Bondi Junction run by Ron Ford, he had a deal with a smaller fin in front of the main single fin.
It road OK, remembering that the riding style was different back then. What I 'member is that it drove off the back dominant fin but when you weighted forward, the smaller forward fin came into play and it lost its drive, bummer…the fins were 12 in apart.

Also , could you use a long bahne / fins unlimited back fin box ? [the Peter Crawford fin box in my ‘Bushfire fish’ is 14"]
cheers mate !

Hey Cheyne - Thanks for the reply. Just quick question: How are you putting your fins on - box, glass, screws, etc.?
I’ve spoke often w/Dale S. about having a thin, solid glass tail, @3/8" thick, and drilling holes where ever you want and mounting the fins by tapping the bottom of the fin and screwing 'em down to the bottom through the deck… That way one could put fins all over the place with ease.
I’m often struck by the change I get my moving a fin a 1/4" or less, esp. the center fin, but still, so much to be learned from such small pieces of the equation… some times blows my mind to much.
Here is a question about the board in question: Given that it is so thick and wide, it catches waves well, but once the size/power got beyond a certain point (@ head high thick reef suck off peak) I would hit the bottom on the drop, and when I went to turn it would either go straight, and I’d fall off - like I was kinda trying to milk it, or if I leaned hard into it, it would spin out.
So, the question/hypothosis is, if I put more fin on the tail (I already have big “twin fin” fins on the side), then will I be able to push it around with out spinning it out?
Thanks for the indulgence - TaylorO
ps. Hi Chip - just been workin’ hard, and tryin’ to get some waves… Fall was a bust in these parts… Went from howling summer like wind to howling winter like wind… “Where’s my month of glass/off shores???”
There’s some video out there where Tom Curren chops his single fin in half and glasses the top part behind the original fin- inline. I forget the name of the video though, someone else has to know. Just my .2 cents. -Carl
Hi Taylor -
this is telling you that you can put your fins almost anywhere, when we were kids a friend had one up the nose for tuberiding.
actually an old issue of TSJ had a photo of one of Curren’s boards that had a tiny keel fin up on the nose.
puzzled as to how this works out…
in line fins i saw were two 9" flex fins .talk about twang and drive!
Seems like a cure for the pivoty thing people talk about with Starfins
Thought of this a while ago, and again when I saw Cheyne on this thread in the archive
I’ve gotta getta shed…
