Rated 5 out of 5 by from Works Great I own a 14 ft. flat water kayak and this works great for me. Took some time to get the routine down to get it perfectly secure. It comes with straps but I wouldn't trust them over ratchet straps. The bow and stern straps are an absolute must use. I drove from Denver to Michigan on I-80 going an average of 80 MPH and my kayak hardly moved. My only complaint is the rack is secured by four screws that tend to slide. They don't move much, only a couple inches at most, but it is very easily fixable. Very good product overall and easy to install. They do fold down when not it use, making garage parking a breeze. They also double as a bike rack.

Rated 5 out of 5 by from Gets the Job Done; Durable I've used the stacker on a Ford Fiesta hatchback for about two years now with great frequency and through a variety of weather conditions. Not once have I had any trouble or frustration with the product. My car isn't wide enough to stack four boats but it carries two 8-9 foot kayaks beautifully. Once you figure out the routine of tie downs, your boats will fit snugly even at high speeds. I use two straps for each boat, so you'll want to pick up some extra tie downs. I don't ever use the bow and stern ties on my boats. When I'm not hauling kayaks I actually take the stackers off instead of folding them down. Set up and take down is fast enough that it isn't any inconvenience to me to remove them when not in use, and doing so saves me just a little bit on gas mileage.

Rated 5 out of 5 by from Very nice Bought these when I bought our kayaks (Wilderness Systems Pungo 100, Dagger Blackwater 120). We already had a factory roof rack on our mini van so these worked very nice on the existing rack bars. The nice part is the fact that they lay down in between the bars of the rack when not in use so the van still fits in the garage - SWEET!! Simply loosen the wing nut and lay the support down parallel with the roof top and tighten the wing nut. The supplied straps are plenty long enough. I haven't used the ratchets (ropes). Nice product and reasonable when compared to the other racks we priced.

Rated 4 out of 5 by from Works Like a Charm! I own a small sea kayak guide service and school and have used the Thule Stacker on our company vehicles for years to transport sea kayaks. The best way to transport a kayak is on its side; it's not only space efficient, but reduces the likelihood of causing distortion to your hull. Prior reviews note problems keeping the boats in place to tie them down. That's avoided by using a rack pad (e.g., Thule makes inexpensive sets), a closed-cell foam block, or--for the poor man's solution--a section of a foam pool noodle cut to slip over your bar. I find it easier to load than a cradle, because you only have to lift the boat to the rack height, not over and up into a J-cradle; it also works great with Thule's Outrigger boat lift system. If you use this for longer boats, you'll need to make sure you have a wide enough bar spread. If you have a short roof line and a long boat, this may not be your best choice. Those with composite boats should note that the rack component is not padded. Use foam noodles or rack pads to prevent unnecessary grinding and gouging on your gel coat (it's a lot more fun to get those battle scars from the sea!). Happy paddling!

Rated 5 out of 5 by from A miracle of modern science! This kayak rack is very intuitive. I can fit four kayaks of any size on the roof of my vehicle with ease, and when we arrive at our destination, they unload even easier! The only bad thing about these racks is the price. You also have to have the crossbars already installed on your existing rack before you can use this one. I can't resist saying "Nice rack!"

Rated 3 out of 5 by from Good but should be better I bought this to load two sit-upon kayaks on the roof rack of my Tacoma pickup. The racks are quite sturdy, are easy to install/remove, and easily fold down when not in use. However, there no included pads upon which to rest the kayaks, which must now rest upon the rack's load bars- unless you buy separate/make pads yourself. For the price, such pads should be included or at least be made available from Thule. Also, the top of the stackers is a closed loop through which the load straps must be passed- an awkward at best situation when two kayaks are loaded, and standing in the bed of the pickup. A competing brand utilizes large "hooks" to hold the straps, a much easier method. That brand also includes contoured pads for the load bars, to fit the kayak hulls

Rated 1 out of 5 by from Try a different rack I purchased this rack, my first, in 2007 to transport my two kayaks. It is difficult to load the boats and then secure them. You have to balance and lean the boats against the rack while you get the straps ready. The straps are not rachet straps, and come loose easily. Boats are loaded on their side and one of my boats always slipped during transport.

Rated 2 out of 5 by from The Stacker is only good for rec kayaks. We bought the Stacker so we could buy kayaks and safely transport them home, but our boats don't work with them. We have a Chesapeake 14 Wood boat & a Hurricane Tampico, both of which do not stay up on their side- out of the water. So loading the boats became a balancing act & they would slide down and off. If your boat is the same depth from front to back (like a surfboard, paddleboard)and lacks a keel line or curves, you can probably use this rack just fine.

I need to transport two kayaks, how many of these do I need to purchase?

Asked by: Doug in the Desert
The Thule Kayak Stacker accomodates up to 4 kayaks stacked on their side. It accommodates kayaks up to 36" wide and 12' long.

Are there two of these upright bracing devices per item: one for each cross bar, as shown in your advertisement's graphic representation, or is an order of two items required to achieve that result?

Asked by: Jennifer Mason
​Two vertical mounts are included per package; one for each crossbar.

I am looking to transport 4 kayaks, but the directions do not state if a preferred way to stack the 2 on each side (hulls together, cockpits together, one each way, etc), nor can I find any videos showing loading more than 1 kayak. Any help/advice?

Asked by: Badger Paddler
I placed the stacker to the side on the cross bars so that I can put one whitewater kayak on one side and three on the other. That way, if I am carrying just my boat, I can use short straps to secure it.  If you do it this way to carry multiple boats, do the wide side first with three boats and it is easier to reach the stacker for the single boat last. Put the boat's cockpits facing each other for a nice locking fit.  Also, paddles fit very nicely inside the stacker and lash down easily with one short cam strap.  I routinely carry 2 Mambas and 2 Burns to give you an idea of the size.  If someone has a little play boat, we put it on the outside.
