Aloha! Do you need help choosing a fin?
WE HAVE A CHART SET UP TO HELP YOU!
We also have some quick tips and information, as well as a video! Of course, if you have something specific you want to ask, please feel free to contact us!
We’ve been using this Longboard Fin Chart for nearly 20 years now and it’s helped many dial their fins in. When we first started there was no fin chart like this. As a matter a fact, I don’t think there are many out there even today.
After we had put this fin chart together, we submitted the results to the good folks at Fins Unlimited. A few tweaks and several emails later...
The results are what you see right here!
Just to let you know Fins Unlimited (aka, Bahne Fins) have been around for over 60 years so they know a thing or two about fins. We can also thank them for inventing the adjustable fin box that’s standard on most Longboards and SUP’s.
So on to helping you select the right fin for your Longboard or SUP.
HOW TO FIND YOUR IDEAL CENTER FIN, PART 1.
PERFORMANCE, SINGLE, 2+1!
There are two basic ways to ride your board: “Single Fin” or “2+1.”
- Single fins are good for small days. And, of course, most classic boards come standard with a single fin setup. However, the pivots and turns are not as stable compared to a 2+1.
- 2+1 is the more standard fin set up. It’s usually a large center fin with small side fins (aka, side bites). It’s stable and easier to generate speed. The turning radius is wider and feels tighter compared to a single fin set up. Some of the old timers call the side fins training wheels because it stabilizes the board.
Once you decide on the fin set up, you’ll want to go to Step 2.
HOW TO FIND YOUR IDEAL CENTER FIN, PART 2.
GREENOUGH 4A, CJ NELSON DIAMOND, TAKAYAMA HALO FIN.
To keep things simple, I thought it would be best to introduce the three main types of fins. Also, to go over one unique fin in particular as it's been our #1 selling fin for over 15 years!
It has a wide base with a long rake and a pointed tip.
Mind you, not all have this small (pointed) tip, some are more blunt. But the feel when you ride this is basically the same.
You’ll get a solid drive down the line and the turning radius is long and drawn out.
More Rake + Smaller Tip = longer turn/drawn out turns (longer turning radius).
So the opposite is also true: Less Rake + Blunt Tip = Shorter turning radius.
Just in case you are not sure what rake is, it’s the curve of the fin.
Just above the base it’s cut out which is how it gets its name.
This fin’s turning radius is smaller than a traditional rake fin and looser, meaning it’s not as stable. Most people who get this fin want the hold of a rake, but enough looseness so they can move the board around for rail riding.
Donald Takayama actually designed these fins back in the day. It’s made to help the board pivot in a small radius and keep the board stable while nose riding. You don’t get a lot of drive out of the fin, but it’s perfect to use for cruising and cross stepping to the nose.
Which is the Takayama Halo Fin.
“Halo” means fin, and no other fin on the market can come close to it.
It’s a combination of the pivot, rake, and cutaway fin rolled up into one fin. It’s been our #1 selling fin for over 15 years with tons of positive reviews.
The fins will make your board easier to turn with less effort and more speed. If you’re looking for a fin to give your old board new life, I highly recommend this fin.
For Single Fins go up 1/2” to 1” longer. If you want the same stable ride as the fin you're using now and want to try a Halo fin, go up 1/2” for the same stable ride, but easier turning and guaranteed added speed.
NOTES TO CONSIDER...
IF YOU WANT TO TRY SOMETHING DIFFERENT.
- If you want a higher performance style of surfing like a shortboard:
For your Center Fin, you’ll want to go 1/2" to 1" smaller than what is recommend on the chart. You’ll also want to pair this with thruster size side bites. Do not keep the same small side bites that are standard on the longboard, it’ll slip and you’ll lose drive.
- If you want something really different that’s been trending for the past couple years: ride it Twin Fin style. The board will have more drive, surf rail to rail, and still be loose off the top. For this set up, I recommend going with X-Large side fins. You’ll also want to go with a Center Fin that is 1" to 3" smaller that want is recommend on the chart. This set-up is good for up to head high waves. You'll be able to whip the board around and have lots of speed down the line.
