Aloha , Who sells the adjustable fins ? I need the whole setup , Fins , Boxes ,etc. Thank you D.J.
Lokbox does! www.lokboxfins.com
they are “four way fins system” from Australia. try http://www.4wfs.com/ and the contact in the states is: Name: George Mayou Address: Island Style 33 Bawley Street Laguna Niguel CA 92677 Tel: (949) 240-2428 Fax: (949) 240-2428 Cell: 949 2930380 Email: Good Luck…
I had always wanted boxes that I could change the toe of my fins. With Fins Unlimited next door to me, I got 4 of the narrow FU channels and made 2 boxes in the shape of an hour glass. The fins had plates front and rear and could be slid back and forth. I set them into the board with the max outer toe to be straight ahead and the inner toe crossing behind the tip of the stringer. What I found out was, the more toe, the flatter riding the board becomes, straight ahead was where I wound up riding the board, it had the best drive and performed on a rail, as opposed to doing the hop, flicking the board side to side.
You’re looking for Edge Fins from Kauai. See link below. Rob Olliges http://www.edgefins.kauaistyle.com/index.htm
There is swivel fins from Oz, adjustable in toe. There is 4 way fin system, adjusts toe and cant and fore-aft position. There is the Edge system, adjustable in toe. Red-X and Lokbox are adjustable too, perhaps people with them will comment on the degrees of adjustability. Personally, I think fore-aft position is the most important. I think toe-in and cant should be constant across all thrusters, and the parameters to vary to change a thruster for different systems should be ratio of fin sizes, and forward/rearward position in board. Guns use bigger middle and smaller side fins, and space them further apart. Small wave wide tail thrusters use smaller rear fin and have fins closer together (in the forward/rearward dimension). http://www.blakestah.com/fins/
Sounds like your looking for edge systems. Their excellent.

I’ve used and installed both Edge fin systems and of course Red-X.Both Edge and Red-X require specific tools and jigs/guides to complete your box work.I have neither kit but would suggest that you buy there installation kit vs. what I did.I’m lucky enough to have the right amount of odd tools and the skill to use them out of there conventional uses.Both are strong systems and installation rather easily if you follow the instructions.The Red-X system requires a plunge router and a specific jig.Not something you’re just going to put together in a snap.It took me 3 different times using 2 ways to create a way around the factory installation jig and router before I was suscessful with a consistant set-up.The Edge system requires a drill and specific holesaws,guides,and other tools.This installation is also a two stage cut. …The Edge system when installed allows you to rotate you fin in place giving it an ajustable toe-in. …The Red-X when installed allows the user to ajust you fins foward and back 3/4" total. …I think both are fine systems but I prefer the Red-X systems personally. 99.9% of the time I get my toe-in where I like them to be and really don’t need to change it.For some others, the ajustable toe would benefit them more.Plus I like the choice of fin templates Red-X has to offer.They work well with my surfing,plus having the advantage of tuning out the cluster by moving them in optimum positions. …I still use FCS center plugs for my single tabbed Superchargers ,but I’m in the process of making my own boxes in white plastic for this purpose.Herb
Toe-In on a board is perhaps the last design element I want to tinker with on a board. Most boards are either good,excellent or a mile off. Toe-in adjustments on excellent and mile-off boards are a waste of time. Toe-in adjustements on a good board, well its almost a 99% sure thing that whats wrong with that good board to make it better is not going to be fixed by adjusting toe-in. Just my 2Cents.
could it be though, that the reason that a bad board is bad is that the toe in is wrong?
not highly likely.
I had a mini-gun that turned like crap, the toe-in was only 4 degrees. Since then, I’ve taken note of toe on guns and mini-guns. The 4 degree toe-in is just too tracky. I vastly prefer the 6 degree, and slightly smaller side fins. My theory is that the toe-in should be set so that the side fin still has a lot of drive while the rear fin is stalling. This angle shouldn’t change much depending on the tail or type of board. To make a board have more hold you can move the fins further apart, or increase the tail fin size relative to the side fins. I have a David Craig 8’6" gun like this and it works much better, http://www.blakestah.com/fins/
A fascinating experiment is to take an excellent board/fin design and change the toe-in angle… because it can literally destroy the performance. Or just take the fin(s) out and feel the result… The more a board’s performance is dependent upon fin(s) for directional stability, the more important their fine-tuning becomes. http://www.surfline.com/surfaz/fins.cfm
