Thurso Surf Max Multi-purpose iSUP Review

When I first stood up on the Thurso Surf Max Multi-purpose during testing for this review my main thought was ‘wow, this SUP is aptly named.’

The central characteristic of this 11’6 x 34” board is ‘max’imum stability. It’s damn near unshakable; and believe me I tried. I started by shifting my weight side to side and trying to feel at what point the board was going to tip. When that didn’t work, I pushed harder, eventually submerging the right side of the board, and then the left, over and over again and it still never felt like it was going to give. At this point I resorted to standing with my full weight on one side of the handle and then the other, and still no relenting, to which I responded by jumping up and down (if you’re imagining how this looks; it’s kind of similar to the PIXAR lamp trying to squish the letters).

While the jumping is what eventually made me fall off of the Max, it wasn’t because of any loss in stability; it was because I landed weirdly and the board moved out from under me. I’d still put it on the list of SUPs that I couldn’t tip.

Complimented by its stability, is the impressive amount of activities this SUP can take on. Whether it be yoga, fishing, or hauling gear, the Max Multi-purpose is ready with its full length deckpad, built in ruler, integrated action mounts, paddle holders, and more that we’ll dive into below.

So although the Thurso Surf Max Multi-purpose is not the most nimble or quick SUP on the market, it’s poised to accommodate a massive range of paddler sizes, skill sets, and interests. It’s also undergone a bit of an accessory upgrade since we’ve reviewed it last, and we’re excited to share our take on this ultra-stable, versatile SUP.

We think the Thurso Surf Max Multi-purpose would be great for paddlers who

  • Need an impressive level of stability
  • Want a SUP that is equipped for a variety of water based activities
  • Require extra volume to accommodate a heavier paddler, gear, or a passenger
  • Prefer the amount of usable space that comes with a full-length deck pad
  • Are interested and wanting to pursue SUP fishing with a stable, versatile SUP

Performance Review of the Thurso Surf Max Multi-purpose Stand Up Paddle Board

Thurso Surf Max Multi-purpose iSUP Review
The Thurso Max is a heavier SUP, but has tons of stability.
Thurso Surf Max Multi-purpose iSUP Review
Being 31 lbs, stepback turns aren’t easy for smaller paddlers on the Max, but not impossible. (it’s also not something this SUP was intended for)

Because it’s 34” wide, the Thurso Max isn’t keen on perfect tracking; though it does okay for a larger SUP.

Stability Rating: 9.8/10

Stability is where the Thurso Surf Max Multi-purpose stands out, and it’s no surprise given this board’s dimensions.

Being 11’6 x 34” x 6”, the Max Multi-purpose is a high volume board, meaning it’ll take either a lot of weight, or a lot of effort to tip this SUP to the point of falling off. On top of its dimensions alone, the Thurso Max is also rounded and wide throughout, keeping the amount of surface area of board-to-water contact relatively consistent and high regardless of where you’re standing.

Given that this seems to be Thurso’s fishing SUP (as evident by the built-in ruler on the deckpad), the stability is more than welcome. We had no issue walking up and down this board, putting weight on one side, or jostling it around a bit. Through all of my stability testing shenanigans, the Thurso Max held firm.

It’s this level of stability that also leads me to be fairly confident on Thurso’s estimated 300 lb weight capacity for the Max Multi-purpose. I’d be more than confident to throw a cooler on this board, load it up with fishing gear, or bring a long passenger (maybe even all at once).

Speed Test: 7.9/10

Thurso Surf Max Multi-purpose iSUP Review (Sprint)
While most of our larger SUPs finish this sprint test in 01:20:00, the Thurso Max finished significantly slower.
Thurso Surf Max Multi-purpose iSUP Review (Casual)
Paddling more casually, the Thurso Max was still fairly slow, and the board has a ‘heavier feel to it.

In terms of speed, the Max Mutli-purpose is undeniably a slower board. Now, that’s to be expected given its crazy level of stability that we discussed above and its bulkier dimensions, but I think the weight of this board comes into play as well.

The Thurso Surf Max Multi-purpose is 31 lbs, and as a smaller paddler, I can definitely feel it while I’m trying to get this board up to speed. Despite my best efforts, I couldn’t get this SUP to finish our sprint test within the average time frame for a board this size. For reference, bigger boards usually come across the line after 00:01:30, the Thurso Max finished in 00:01:38.

Another contributor to the Thurso Max’s lower speed capabilities could be its nose rocker. While speed testing this SUP, I often felt like I was pushing water and the board seemed to balk at most head-on chop from boat wake. While it is normal for chop and boat wake to slow a board down, it seemed to be even more exaggerated on the Thurso Max, which is an indication that the rocker needs a bit more lift to more easily glide over chop.

That said, I think a taller/heavier paddler would be able to get the Thurso Max going a little bit faster than I could, as they’re able to put more weight behind their stroke. I also want to clarify that it’s not totally a bad thing that this board is on the slower side; if you’re casually paddling by yourself or using it to fish, you likely wouldn’t even notice it. The only area where I do think the speed would hinder you is if you’re out for a long tour with friends, as it could take a little more effort to keep up with the pack.

Tracking: 8.8/10

Thurso Surf Max Multi-purpose iSUP Review
The Thurso Max has a 2+1 fin set-up, centered around a dolphin style center fin. This set-up is geared towards maneuverability rather than tracking and it shows in the performance.
Thurso Surf Max Multi-purpose iSUP Review
Given that the Thurso Max is 34” wide, it’s more challenging for me (a paddler with less reach) to keep 110% perfect form, which would contribute to better tracking.

The Thurso Surf Max Multi-purpose is made to be a sturdy, high volume platform, and because of that, tracking declines a little bit.

With that in mind, the Thurso Max tracks about as expected. You will need to switch sides a bit more frequently than you would on a narrower SUP, but that’s a typical compromise when it comes to ultra-stable boards.

For me, and paddlers my size (5’2 x 135ish lbs) especially, the 34” width on the Thurso Max makes it a little more challenging to keep good form, which helps enable good tracking in the first place. Paddlers that have a little more reach than I do will likely be able to achieve better tracking with the Thurso Max than I was able to in our testing.

I also want to note that the Thurso Max utilizes a US fin box, so if tracking is super important to you, you have tons of possibilities in customizing your fin to fit your preferences.

Maneuverability: 8.5/10

Thurso Surf Max Multi-purpose iSUP Review
At 31 lbs, the Max is more difficult to change direction with sweeping strokes if the board has some momentum going.
Thurso Surf Max Multi-purpose iSUP Review
The higher volume Thurso Max did not want to sink its tail under my weight on the back of the SUP, but it was still possible to do a stepback turn (albeit, a slow one).

Maneuverability is another area where I think the Thurso Max’s weight comes into play.

Being 31 lbs, the Max Multi-purpose does take a bit more effort to change direction if you have some momentum going. Of course, its larger dimensions are a contributor here as well, as most 11’6 x 34” SUPs will be a bit slower to turn. However, when tested at a stand still, the Thurso Max required 5 backstrokes to make a 360 degree turn, which is one more stroke than was needed to make the same turn on the Blackfin XL (tested on the same day, in the same conditions). Though because its slightly lower level of maneuverability seems to be related to the weight of the Thurso Max, it likely won’t be as noticeable for taller/heavier paddlers.

We also tested stepback turns on the Thurso Max, but I do want to emphasize that this is not a board that you’d have in a situation where a stepback turn is absolutely needed. The Max was expectedly a little more resistant to this type of turn than smaller, sportier boards we’ve tested. It’s fairly difficult for lighter paddlers to sink the tail, and even then it turns in more of a wider circle. I don’t think this is at all a problem with the SUP; it’s just simply not what it was built for, and that’s okay.

Construction Quality: 8.8/10

Thurso Surf Max Multi-purpose iSUP Review
The Max has carbon reinforced rails, which add a little bit of added stiffness and a lot of durability.
Thurso Surf Max Multi-purpose iSUP Review
Thurso’s Max has a recommended PSI range of 14-18, with a max of 20 PSI.
Thurso Surf Max Multi-purpose iSUP Review
The Thurso Max sports a full-length deckpad, with cutouts made for the D-rings and other features.
Thurso Surf Max Multi-purpose iSUP Review
Along with the carbon fiber layer, Thurso reinforces their rails with a strip of seam tape.

The Thurso Max multi-purpose is constructed using a woven-linear inner drop stitch and dual layers of fused PVC.

What this means is that the thousands of threads holding the shape of the Max intact are oriented linearly (parallel to each other), running from deck to bottom of the SUP’s interior. These threads are then anchored into a woven fabric layer, which is eventually coated in two laminate layers of PVC, thereby ‘fusing’ together during the drying stage.

Once the deck and bottom layer of PVC are dry and solidified, Thurso applies the Max’s rails. Like nearly all Thurso boards the Max multi-purpose has a strip of carbon fiber fabric incorporated into its rails, which slightly improves stiffness.

While I’d like to see Thurso tweak their materials and processes a little bit to take some weight off of this SUP, I also want to acknowledge that this SUP will be durable enough to hold up to a lot of abuse and it’s ‘heavier’ build makes it fairly rigid on the water to sustain higher weight capacities.

Board Stiffness:

The Thurso Max before we placed 150 lbs on it during our bend test.
Thurso Surf Max Multi-purpose iSUP Review
The Max bent just a hair over 1” under 150 lbs.

Stiffness Test: 1.0625” Bend

Our bend test is performed by placing the SUP on top of two sawhorses that are spaced 7 apart. We then set 150 lbs at the SUP’s midpoint and measure how much it flexes under the weight. Of course, this is not replicative to conditions on the water, but it does help us understand how different construction techniques contribute to overall stiffness.

The Thurso Surf Max Multi-purpose bent just slightly over an inch in our bend test. While this is slightly more than we expected, it’s still mostly on par with some of the stiffer SUPs in our data pool. Moreover, when it comes to on-the-water performance, the Max multi-purpose feels rigid under foot and I’ve had no issues with it supporting my weight + my dog + some gear.

Features/Accessory Review: 9.2/10

Looking at the sheer amount of features on this SUP, it’s evident that Thurso Surf really took the term ‘multi-purpose’ to heart.

Thurso Surf Max Multi-purpose iSUP Review
Features from left to right: rear carry handle, leash D-ring, rear cargo area w/ 2 integrated action mounts, pair of safety grab handles, center carry handle w/ paddle holders and kayak seat D-rings on the rails to either side, built in ruler, second pair of safety grab handles. Front cargo area w/ 2 more integrated action mounts, nose action mount, nose carry handle.
Thurso Surf Max Multi-purpose iSUP Review
The max utilizes a 2+1 fin set-up with a US fin box on each. This allows a lot of customization ability while still enjoying the convenience of the included Kumano click fins.
Thurso Surf Max Multi-purpose iSUP Review
The Max’s rear cargo area is slightly smaller than the front, though it does still have the 2 integrated action mounts.
Thurso Surf Max Multi-purpose iSUP Review
Each of the Max’s 4 action mounts provide the ability to attach a cup holder, go pro, rod-holder, etc.
Thurso Surf Max Multi-purpose iSUP Review
The front cargo area of the Thurso Max is fairly large and easily fits a few drybags worth of gear.

The Thurso Surf Max ‘Multi-purpose is equipped with large front and rear cargo areas, with both sporting a pair of integrated action mounts (making 4 total, for those of us not talented at quick maths).

Thurso Surf Max Multi-purpose iSUP Review
The Max’s brand stamped and diamond grooved deck pad is the perfect balance between grip and comfort.
Thurso Surf Max Multi-purpose iSUP Review
We like the Max’s built in ruler, as the stability on this SUP is great for SUP fishing.
Thurso Surf Max Multi-purpose iSUP Review
The velcro paddle holders secure your paddle out of the way if you’re fishing, swimming, and practicing yoga.

They’ve also added a built-in ruler into the full length deck pad for easy measuring when you reel in a fish. Fishing was likely in mind when Thurso equipped the Max multi-purpose with a set of velcro paddle holders on both rails, as well as extra D-rings to attach a kayak seat.

You’ll also notice that the Max Multi-purpose has 2 pairs of grab handles in addition to the nose, tail, and center handles. While I’m not exactly sure what these are for, it does help when you’re getting back onto your board after going for a swim and it gives passengers something to hold onto while riding either in front of, or behind, the paddler.

Included Accessories:

We love the included Kumano fin for it’s ease of use.
Thurso Surf Max Multi-purpose iSUP Review
Thurso added a new accessory pouch to their kit, which helps tremendously with organization.
Thurso Surf Max Multi-purpose iSUP Review
The pouch can be used to store your leash, fins, and repair kit items.

With each Thurso Surf SUP, you’ll receive the following accessories:

  • 3-piece carbon hybrid paddle
  • Accessory pouch/ organizer
  • Hatchet-style kumano fin
  • 10’ coiled leash
  • Dual-chamber triple action hand pump
  • Wheeled SUP backpack

While the list remained roughly the same from previous models, the latest line-up on Thurso SUPs got a bit of an accessory upgrade.

Thurso reworked their SUP backpack to be much roomier than the previously included bag. It makes it so much easier to pack up your SUP and gives you space to throw in some extra gear too. I also really like the new material, and that Thuros has added mesh patches to the bottom of either side to limit the chances of mold if your SUP is put away wet. They’ve also swapped out their snap-lock fin set-up for a kumano click fin set up, which opens the door for tons of customization.

Bag and fins aside though, my personal favorite upgrade to the Thurso Surf accessory list is the addition of an accessory organizer. This little pouch honestly reminds me a lot of my dad’s travel toiletry bag. It folds up into itself and has individual zipper pockets for your fins, leash, repair kit items, and tools. As someone with zero ability to keep track of small pieces, the organizer pouch is a life saver. I also love that it fits perfectly into the front exterior pocket of the new SUP bag.

More important than the upgrades though, we were ecstatic to open up this SUP package and see that Thurso has swapped out single use plastic packaging for paper and cardboard.

Summary Review of the Thuros Surf Max Multi-purpose SUP

The Thurso Surf Max Multi-purpose is understandably not the most nimble or quick SUP of the bunch, but was instead built with stability and versatility at the forefront of its design.

Measuring in at 11’6 long and 34” wide, the Max Multi-purpose is a nearly unshakeable platform in the water, and it’s poised to serve taller/heavier paddlers as well as paddlers looking to load up with passengers and gear.

It’s also loaded with features to accommodate nearly any activity you could throw it’s way. SUP fishing will come easily with the built in ruler and action mounts, you’ll have enough room for yoga with the full length deck pad, or you can opt for a more lax experience by attaching a kayak seat to the extra D-rings.

In short, the Max Multi-purpose easily lives up to its name in offering ‘max’imum stability and ‘multi’ple options for your paddling experience. In the future though, we’d love to see thurso cut some weight from the overall build of this board.
