Finologist Larry Allison Explains 4 Fin Race Twin Layout on a Raceboard

Why does my Paddleboard only have 1 fin??

My name is Marc and I like to think of myself as a Surfer,,,,,, I have a quiver of boards and except for my current longboard all of my other boards have multiple fin options yet my 14′ SUP raceboard has 1 fin and no expansion options for different conditions so I’m confused.

If you asked me if I wanted to go Surfing or Paddleboarding I’d say Surfing then Surfing, then tacos, and then a paddle. It’s simple for me –  the adrenaline rush of getting on a wave on a surfboard can’t be duplicated. As a Surfer I have a better than decent knowledge of how fins work and what works best in different conditions and what setup I like for different boards in the quiver. If you Surf you totally understand that changing the fin setup on your board can completely change the performance. Paddleboarders for some reason don’t seem to understand that the same fin principals are at work on their Paddleboards. They buy a board and off they go.

Think about it – most surfboards made now have 5 fin setups standard so you can run your stick as a single fin, twin fin, quad, thruster, or 5 fin. If the changes from one setup to another didn’t make a difference they wouldn’t make boards with multiple setup options? Go buy just about any Paddleboard like I did and you have 1 fin and only 1 fin option. Wait, what 1 fin? I mean my Paddleboard is 14′ and I ride between a 5’7 and 6’0 surfboard and I can run 5 combos and up to 5 fins at a time??? Yes, yes, yes, I only use 2 combinations, (either thruster or quad) but their is a big difference between the two on how the board reacts. It appears to be obvious that additional fins on a Paddleboard would change even the basic dynamics of the board. a dorsal fin should help with side rollers and current right? Adding a twin setup at the rear should help propulsion right? What about a quad setup? I mean it does work on my surfboard.

After seeing the 4 fin setup on a few SUP race boards I asked around and was told that I should give the “Finologist” Larry a Call.

So I sent Larry a DM on IG, (cause I’m current on tec.). Larry responded and told me to give him a call. I called and told him who I was and what I did and then we spent about an hour on the phone while Larry explained everything about the 4 fin / ProBox setup. It was eyeopening and confirmed my initial thought that Paddleboards should have more fins and more importantly why.

If you don’t know Larry and you like to Paddleboard or better yet RACE your paddleboard you need to get on board with what he is saying and how he is changing the way race boards perform.

Here is our take: Larry is the foremost and “OG” Finologist in the world. Larry also makes some of the most badass SUP fins that one can buy and we’ll be reviewing his fin line in future posts.

Here’s a taste of some of his fins: they can be purchased at local retailers or go to and select LAFins

Get Larry on the phone for 2 min and you’ll know Larry is the real real. A 5 min conversation with Larry and your mind will be obsessed with thoughts of changing your race board to a ProBox setup. A 10 min conversation and you’ll be asking for his address to ship your board to him for a retro fit without ever asking or thinking about the cost, which is very reasonable BTW.

I’d bet that more than likely if you did get him on the phone you’ll spend an hour with him while he gives you the master class in “Finology” and this won’t be your typical 101 level class we’re talking the PHD level class so pay attention people. Their won’t be a test after you get schooled but if you fail to pay attention you’ll keep finishing at the back of your age group at the next races.

Some of Larrys handy work:

So here at we don’t have a team of internet fin historians and fact checkers to check this next statement for accuracy but at we believe that Larry is the OG and creator of the ProBox system or in layman terms putting 4 fins on a Paddleboard. If we’re wrong whatever but we’re not wrong that he has perfected the system. Yes the setup has been copied by others that chose not to work with Larry and they will tell you that their setup is “better” and have a good marketing statement to go along with it.  The reality is that other stock 4 fin setups aren’t as good as they have made slight changes to critical measurements to call it their own and slight changes in measurements has big effects on performance.

If Larry did the retrofit on a board or he gave someone the template using his measurements then his setup is better than others. (period).

Here’s a video of Larry explaining the 4 fin race twin layout:

If you race your paddleboard get in touch with Larry about getting your board outfitted with the ProBox system he is the OG, PHD Jedi master of the setup.

ZRE Paddles – Power Surge ZX4 SUP Paddle

SUP and SURF reviews got our hands on a complete quiver of ZRE paddles and have been putting them through their paces for the past month.

We’ll be reviewing 3 ZRE models over the next month:

Power Surge ZX4 SUP Paddle

Power Surge Outrigger Light Paddle

Razor R-1 Dragon Paddle XL

All ZRE paddles can be purchased directly from ZRE ( tell Bob we sent you ) or from shops on our partner site or via the classifieds link at the bottom or right of this page.

Recently on a trip to San Diego I left my paddles at a friends house figuring I’d pick them up before heading back to AZ. So that never happened and when I realized that I was sans paddle for the Tuesday night paddle with Riverbound Sports in Tempe AZ that I like to go on I called Corey who owns Riverbound Sports along with his wife Teri and asked if he could let me use one of his paddles for the night or a week or till well whenever I got mine back. Being a good dude he said yes and brought me his ZRE Power surge to use. Not knowing much about ZRE except they were supposed to be good I asked the usual question “you like this thing”? Corey responded simply “yes I seem to always reach for it for my racing”. “I really like it”.

The Tuesday paddle is basically a sunset chit chat paddle with some “efforts” if one gets board. We paddle around Tempe Town Lake witch is roughly a 5 mile lap on really really really flat water that has a particular scent with slight nodes of not so clean water. But the sunset is 10/10. ( Thanks Teri for the Photo,,)

I grabbed the paddle and off we went. After only a few strokes I was in love with the ergonomics. ThePower Surge blade design is curved at the bottom blade, and is slightly concave on the power face for a quick catch. The rib design assures positive tracking through the water, eliminating flutter. The one piece carbon fiber shaft is tapered oval, providing strength, comfort, and positive tracking. The carbon palm grip with finger recess completes this 100% carbon thunderbolt.  I Need to get my own,,,,,,,

The next day I contacted Bob Zaveral whom is the owner of ZRE or “Zaveral Racing Equiptment” and had a conversation about the paddles in general and the technology behind them. Bob to sent us a range of product to test and demo out that we agreed to purchase from him. Yes – will let you know if the product we are reviewing is purchased or “on loan”. We know that many readers feel that when we are given product to review that we have to only show the positives of the product and may be biased. So whenever possible we’ll purchase the product and then sell it off as “demo” or “reviewed” product on one of our partner sites or here on our blog so you know that we are giving an honest unbiased review. If we ever are biased towards a product we have no problem telling you up front and will do so.

For the Power Surge ZX4 I chose a 78.5″ overall length with a 7.25: blade with the standard 12 degree blade angle, and Palm grip. You can select ANY blade angle from  0-15 for a nominal up charge.


ZRE makes it super easy to customize your stick so you can select the exact size for your particular style and needs. Over 127 lengths, 14 blade sizes, and 15 blade angles!

I am 5’11” tall and 175 lbs. with “monkey arms” so I could have gone a bit longer, and had I chose a larger blade I may have chosen more lenght but I wanted this stick to be a quick cadence motor so I went a bit shorter.  Typically I use between 78-80″ in length and have used up to an 8.25″ blade. Unlike most,( or all ), other brands – All ZRE SUP paddles are available in basically an unlimited range of sizing including adjustable or fixed length, and anywhere from 62.25″- 94″ in length ( by 1/4″ ) with blade sizes from 6.5″ (80sq) to 9.75″ (13sq) ( by 1/4″ ). That’s a crap ton of sizing to select from. And should you need to cut off that 1/16″ to really be, well anal, you can simply heat up the shaft near the grip and remove it to shorten the shaft.

Favorite part of the paddle:

The tapered oval full carbon shaft! I’ve got good sized hands and the round shafts always tend to give my hand cramping issues. The oval design of this shaft is ergonomically perfect and results in way less hand fatigue.


The ZRE Power Surge ZX4 is GREAT! The shaft is super stiff, I mean F1 Car engineered stiff. Their is zero flex in the shaft that I can feel. Their is minimal blade flex mostly below the joint of the shaft where it meets the blade but I doubt anyone can really feel it out of the water. The rib design of the blade creates a consistent smooth pull throughout the entire stroke, and I had zero flutter that you tend to get in lots of other blades.

The Retail on this setup is $439.95 and the paddles are 100% made in the USA putting the ZRE right in line with the other high end brands, and while that price point may turn some heads a great paddle is 100% worth the investment. A great paddle will make your Paddleboarding experience much, much better. You’ll go faster and further with less effort.

Werner Paddles Zen 95 Review

You can find these and other paddles for sale on

Werner Paddles recently released its Zen series of stand up paddles with a new adjustable lever-lock system.  The largest blade in the series, the Zen 95, was sent to Stand Up Journal’s headquarters in Maine for review.

Billed for it’s versatile use, the Zen paddle was tested in frigid winter North East surf and Maine’s whitewater rivers.

Zen Paddle Review Jeremy Cass Werner river

Jeremy Cass, a river surfer, reports the Zen 95 holds up in the white water, able to sustain rock strikes with minimal damage and performs well.


Upon taking the Zen 95 out of the box, one can immediately see and feel the Zen’s clean lines and solid build quality throughout the whole paddle.

On river, the lever-lock system was rock solid and easy to adjust even when using large neoprene gloves.  While paddling the rapids, there was no noticeable play in the extension system, and the t-grip offers a ton of control for bracing and maneuvering through powerful currents. Cross strokes are smooth and in control when crossing eddy-lines on river.

Werner Paddles Zen 95 adjustable

The adjustable shaft on the Zen allows riders to tighten up or lengthen their stroke according to sport and terrain, from flat water paddling to river surfing.


The paddle held up well to a couple of rock-strikeswith only aesthetic scratches. It was even used as a support-staff to climb steep and slippery riverbanks with no issues.

The angle of the Zen’s blade and feather light construction allows for smooth transfers of the paddle from side to side while surfing.


In the waves, adjusting the length of the paddle by using the measurement markers allowed for an easy transition from a large inflatable river board to high performance sup surfing where a shorter paddle is ideal for balance and acceleration.  The paddle shaft is marked in centimeters for length as well as to a person’s height, i.e. 5’10”.

Werner Paddles Jeremy Cass Zen Paddle

The adjustable power of the Zen Paddle is measured in both centimeters and by height making for easy transfer of length according to each paddler’s needs.


The Zen shines during maneuvering strokes, feathering and cross-strokes. The blade enters and exits the water without flutter or ‘catching’, and really feels like an extension of the body connecting paddler to the water.  The blade’s mellow concave does not trip on the wave-face and transitions effortlessly for cutbacks.

The Zen feels one with the water and really frees your intuition into the next move. In other words, it’s really fluid and fun.

Sliding down the wave face, Werner’s Zen had purchase and fluidity, not catching on the water’s surface but creating leverage needed in turns.


Although the larger of the blade sizes were tested, the paddle was short on power, which required some planning when ferrying across big river features and timing entry into waves.  The medium flex on the shaft is easy on the body and shoulders.  Size and flex will work for a variety of body shapes and sizes.

Zen colors include: Abyss/blue, Coral/pink and Caribbean/green. A full rainbow of stoke!


Additionally, the new colors are fantastic!  Plus, the paddle is backed by Werner’s legendary reputation for durability.  If you only surf or run whitewater and need an adjustable paddle, Werner offers more specific blade and lay-up options with its new lever-lock system.

Ultimately, the Zen 95 will work for almost any paddler and enhances playful movement in all kinds of water.
