The Aire Tributary Spud is a little powerhouse of an inflatable kayak that is intended for kids. Here’s a first-hand review of the Aire Tributary Spud inflatable kayak, a small and affordable whitewater boat that works well for smaller adults and teens.
When a friend paddled past us in a Spud on a recent Gunnison Gorge trip, she looked like she had just discovered fun for the first time. So I was determined to find out what she loved about this boat.
I didn’t realize it was a boat for kids at first—and it turned out, it didn’t matter. Once you start digging into some user reviews of the Spud, you’ll see that many adults have co-opted this sweet ride for themselves. (Check out our review of the Aire Tributary Tomcat if you’re looking for a top all-around IK for adults who want to paddle solo or tandem.)
Audrey Crockett (co-founder of RiverBent) and I rented a couple of Spuds and took them out on the Poudre River northwest of Fort Collins when the water was low but still had a few waves in it. We paddled the Filter Plant section, which is a beginner run with just one notable rapid, Mad Dog.
We concluded that the Aire Tributary Spud would be a fantastic boat for any family to add to their caddy, especially families with young teenagers. Here we’ll discuss the Tributary Spud specs, rigging, features, and how it handled on the water.
Where to buy
Quick links to the boats mentioned in this post:
Small but mighty
The Aire Tributary Spud inflatable kayak weighs only 21.5 pounds, is 7 feet 2 inches long, and 35.5 inches wide. It has a max load capacity of 220 lbs, which makes it a reasonable choice for many adults, especially if you’re not planning to carry much gear in it.
The Spud is extremely easy to roll into a small package and put in the tiniest compartment of your tiniest car. The compactness and lightness of this boat was a revelation, giving us visions of easily hiking in to previously inaccessible put-ins. The Spud seemed like a boat you should simply have in your car at all times just in case, right next to those essential jumper cables.Â
Solid construction
The Spud is made of the same solid stuff as the Aire Tributary Tomcat: 23-ounce, 1,000-denier PVC, which is a standard weight for high-quality inflatable boats, including rafts. As a longtime owner of two Tributary Tomcats, I can attest that this fabric is tough. It has two air chambers (the Tomcat has four), a couple of D-rings, 12 cargo loops (seems excessive, but you’ll likely use them all, for reasons to come), and a couple of carry handles. The tubes are big for such a small boat—11.5 inches in diameter, which makes it impressively stable in whitewater.
Rigging and accessories
The Spud has exactly the same set-up as the Tributary: A pillow-like backrest that you inflate in a few seconds by blowing on the inflation tube, high-quality valves, and those 12 cargo loops. The numerous loops make it easy for you to adjust the seat backward or forward in the boat, affix thigh straps (always recommended!), and strap in other gear. Unlike the STAR Viper (although a great, small inflatable kayak), the Spud has at least some room for gear. You can easily strap in a small dry bag and a hand pump. (Check out my review of the STAR Viper for more details about that boat.)
Although the Spud doesn’t have a footrest, you don’t really need one because it’s so short. If you’re taller than 5 feet or so, and you’re using thigh straps, you will naturally be sitting upright in an assertive stance with your knees drawn up.
The Spud has the same high-quality valves as other Aire boats, including rafts, which means you don’t need any special sort of pump to inflate it. Check our post with tips for choosing an inflatable kayak for more notes on this topic, but in general, look for inflatable kayaks with C7 valves, also called military valves or raft valves, that accommodate a typical raft pump.
Handling on the water
The Spud is very maneuverable and zippy on the water, stable in waves, and turns easily. I would knock a few points off for its sub-par tracking: It tended to spin in swirly waves and was a bit harder than expected to keep headed downstream in slower water. After testing the Spud on the Poudre, I bought one of my own and ran it through Browns Canyon on the Arkansas River, and I got knocked around a good bit in Zoom Flume, which has various lateral waves.
The Spud isn’t a good candidate for rolling as it doesn’t have the kind of decking that you’ll find in a high-performance small IK like the STAR Viper or the Aire Force, which I haven’t paddled yet but looks to answer the same need as the Viper.
Accessories you’ll need with the Tributary Spud
The Spud comes with a repair kit, but not much else. Check out our post on essential accessories for inflatable kayaks for a full list of gear you’ll need. In particular (as mentioned before), we always recommend thigh straps for inflatable kayaks. They make a huge difference in your ability to paddle assertively, brace in big waves, and stay in the boat.
Other essentials include:
- Kayak paddle: I used the same Werner two-piece kayak paddle for paddling both the Spud and the Aire Tributary Tomcat)
- Kayak-specific PDF: I can highly recommend both the Stohlquist Betsea PFD and the Astral Layla)
- Helmet: My favorite is the WRSI Current helmet as it has a great visor, excellent padding, and adjustable straps so you can dial in the fit
- Paddling shoes: I prefer close-toed boating shoes like the Astral Brewer3.0 (for more recommends, check out 4 Types of Shoes Every Paddler Needs)
- Kayak pump: Hands-down, the best inflatable kayak pump is the K-Pump 100, which can handle the Spud in about 8 minutes.
Thumbs up on the Spud
We loved paddling the Tributary Spud—so much that I bought my own used at a boat swap. At less than $500 new, I think this boat is an easily justifiable boat for families with teenagers or adults who want a convenient, packable IK for intermediate whitewater.
