Surf Trux version!
Swaylocks revolution!
Greg,
Looks like you were right on the money!
Solo,
Thanks for sharing! So cool! Might need to install some more fin boxes…

funny, I was just thinking about that.

Hi Superfatpat and janklow, With respect to the Surf Trux Version, the Quadfires are a expandion from the Spitfire (Wingless) Keel Center fin, which comes from the Horan Keel. Also Quadfire and Trifires are all reverse raked fins, not a Sweep or Pivot raked fin at all like Surf Trux or Pavel set-ups . Solosurfer and I have been working on this concept together since the making of the Spitefire single fin for some time. Hope this gives you a better vision of the Quadfire concept which has it’s own style. Mahalo
What angle is the dark blue insert?
Surftrux - no, I wouldn’t want that. As I understand the Spitfires, the reverse rake makes the water travel up the fin & release back along the tail of the board rather than the tip of the fin. This way, the water actually does what the shaper wanted it to do along the tail. But I suspect that the fins would hardly rotate at all…
Is there anybody in UK selling your Spitfire fins? I’d like to get hold of one for my longboard. If not who sells to Europe from the US?

Got it. Thanks Benny and Larry.

Haha, double cheeseburger rails! That is one of my favorite descriptions. I’ve actually tried my spitfire on my 11’ softop, and had a blast, no spinouts even when on the front third of the board. Waves were in the waist to chest range, beachbreak, but not dumping. How far forward or backward did you have the fin? If I remember right, I had it more than halfway forward in the box, and you like it in the back of the box on your other boards.
Sideslipping in beachbreak on a 12 foot board…yikes, that does sound like fun, though.

Oh yeah! Sorry, Larry–great stuff–no toe-step meant! Getting some ProBoxes soon–love your stuff!

For the record the spitfire template will cause less turbulence than almost any other. It is an ultimate speed fin outline. The fin will not interfere with the what the board wants to do so if you have a board that really want to as complete a feel for how it performs put one of these on. Just make sure that it’s deep enough so the board doesn’t want to spin out and place properly in the tail rocker. You’ll no doubt get as much straight away speed as the board is capable of with a single.
Mahalo, Rich
Janklow, Thanks for pointing out the similar aspect of the Quadfire to the others so I could explain, alot of others made the same comment to me. Thanks for your ProBox interest. Mahalo,Larry
SuperfatPat, Thanks for your imput. Mahalo,Larry
BCo - all the way back, baby

What’s the proper way to place the fin in relation to tail rocker? I have a bad habit of just moving the fin all the way forward for looseness but I’m sure that means I’m missing the sweet spot with many fin/board combos.
hey solo,
show us more of that board the new fins are in!

Hi BMG…long time no see. Give me a call when you get the chance. Larry sent me that pic…I will ask him to post the board. More Horans on the way also. My shoulder is acting up again…so…I have not been surfing for awhile.
I’ll give you a holler. Sorry to hear about your shoulder. I paid a visit to your buddy Steve Forstall recently while I was down in FL. I saw lot’s of interesting things in his shaping bay.
Fin position…good question. I’ve played with position on my 8’ fatty, and I like it about half way back. All the way forward was way to unstable for me, at least in small surf. Couple inches from all forward, better stability, but still not much drive. Halfway back, good drive, good turning, good stability, so I haven’t gone any further back. Benny1 likes his all the way back…more drive? I’m guessing (and drawing from my interpretation of Benny1’s softop slip experience) on a board with tons of tail rocker, all the way back is a recipe for slippage.
As far as matching with the rocker, I’m guessing that the more upright the fin is, the more you take advantage of its low drag capacity. So, if you have a lot of rocker in the tail, further forwards is likely to yield less drag. Benny1, Halcyon, Larry, and Solo…thoughts?
