Thurso Max Review
The Thurso Max is a genuinely capable do-everything board that earns its price for anglers, bigger paddlers, and anyone who values rock-solid stability over speed — just know going in that all that platform comes with real trade-offs in weight and maneuverability.
The Thurso Surf Max sits in an interesting corner of the inflatable SUP market: it’s big enough to fish from, stable enough for a nervous first-timer, and built well enough to take seriously as a long-term quiver board. At 11’6″ x 34″ x 6″, it’s one of the widest multi-purpose iSUPs you’ll find at this price point, and Thurso stacks on enough D-rings and deck real estate to back up the “do-everything” claim. Whether it actually delivers depends a lot on who’s standing on it.
I spent time on the Max across flatwater paddles, a half-day fishing session, and a mellow downwind run — and I came away with a clear picture of exactly who should buy this board and, equally important, who should probably look elsewhere.

Stability & On-Water Feel
This is where the Max genuinely shines and the reason most people should consider it. Thirty-four inches of width is a lot of board, and you feel it the moment you stand up — even in a light chop, the platform barely registers the movement. For anglers casting from a standing position, that’s not a luxury, that’s a requirement. For nervous beginners who’ve been white-knuckling a narrower 32″ board, it can be genuinely transformative.
The double-layer woven drop-stitch construction inflates to a stiff, almost rigid deck at the recommended PSI, which means you’re not sinking into the center of the board the way you might on a cheaper single-layer iSUP. The stiffness translates directly into confident, predictable tracking on flatwater. That said, the Max is a long, wide slab of air and it paddles like one. Don’t expect it to pivot quickly or respond the way a sportier 10’6″ board does. If you’re a smaller or lighter paddler who just wants to cruise a coastal bay, the sheer size of this thing can feel like you’re maneuvering a dining room table. Speed-hungry paddlers will also notice the drag — the Max is built for platform, not pace.
Fishing & Gear-Hauling Features
Thurso clearly put real thought into the fishing use case here. The deck is loaded with D-rings — front, rear, and along the rails — giving you legitimate attachment points for a fish finder mount, a cooler, a crate, or a dry bag. The bungee cargo systems fore and aft can hold a surprising amount of gear without cluttering the standing area, and the high weight capacity (rated around 390 lb) means you can actually load it up without worrying about sitting low in the water.
If you’re looking at the broader category, our roundup of the best fishing paddle boards breaks down how the Max compares to dedicated fishing SUPs and sit-on-top alternatives — but for an iSUP that has to do double duty as a recreational board, the gear integration here is genuinely above average. The non-slip deck pad covers most of the standing area, which matters when you’re shuffling position to land a fish or repositioning a rod holder. A passenger or a dog fits comfortably on the rear platform without destabilizing the board, which is a real-world test a lot of SUPs quietly fail.
Construction & Kit
The dual-layer construction is the backbone of the Max’s stiffness and durability story. It adds weight — more on that in the cons — but it also means the rails hold up to repeated loading, rope rub from anchor lines, and the general abuse a fishing board takes over a season. The included carbon-shaft paddle is a genuine plus at this price tier; a lot of competing packages bundle aluminum paddles that add unnecessary weight on long paddles. The carbon shaft keeps swing weight manageable even on a wider board that demands more reach per stroke.
The package includes a high-pressure pump, a carry bag, a leash, and the paddle. The carry bag is backpack-style and fits everything without a fight, though at the Max’s rolled weight you’ll feel it on a long hike to the water. Thurso’s build quality and customer support reputation hold up well across the board line — if you want a deeper look at how the brand performs overall, our Thurso brand review covers the full lineup. Nothing in the kit feels like a throwaway inclusion, which isn’t something you can say about every iSUP package in this price range.
Who It's For
The Max has a pretty specific sweet spot, and the buyers who fall inside it will love it. Anglers are the obvious primary audience — the gear attachment system and stability platform are purpose-built for standing casts and awkward weight distributions. Bigger or heavier paddlers who’ve struggled to find an iSUP with a weight capacity that doesn’t leave zero margin for error will appreciate the 390 lb rating; our guide to the best boards for heavy riders puts that capacity in useful context against the competitive field. Yoga practitioners and photographers who need a steady platform rather than a fast one round out the core audience.
Who should look elsewhere? Lighter, more athletic paddlers who want to cover distance or play in moving water will find the Max sluggish and unwieldy. If you’re under 160 lb and your goal is fitness paddling or touring, the extra 4 inches of width the Max carries over a standard all-around board will work against you far more than the stability works for you. The Max is a purpose-built stable platform — treat it like one and it rewards you, ask it to be something it isn’t and you’ll be frustrated.
What we liked
- Exceptional stability — 34" width is reassuring for beginners and critical for anglers casting from a stand
- High 390 lb weight capacity handles gear loads, passengers, and larger paddlers without sitting low
- Generous D-ring and cargo layout gives real fishing and hauling utility, not just token attachment points
- Stiff double-layer construction inflates to a rigid, confidence-inspiring deck that rivals harder boards
- Carbon-shaft paddle included in the package is a genuine value add over most competing kits
The catches
- Heavy and bulky — the dual-layer build and large format make carry and transport noticeably harder than lighter all-arounds
- Slow and hard to turn — the wide, long platform trades speed and agility for stability, and you feel that trade-off on every paddle
- Overkill for small or light paddlers — at 34" wide, the Max can feel unwieldy if you just want a comfortable recreational cruise
