Most Popular Vortex Bar for 2018 GMC Terrain

've previously used the Yakima Kayak Stacker (old style), which worked fine but I always worried the straps would slip off the hook at the top while I was loading boats. They also didn't fold down, so had to be removed after use unless you wanted to look odd and cause a whistle while you drove down the road. They didn't have a universal attachment option, requiring adapters depending on the style and make of your crossbars. More recently I got the Thule "The Stacker", which is a superior solution. You thread the strap through a closed loop at the top, so you don't worry about straps slipping off while you're loading boats. They fold down after use and have a universal style attachment that fits around most styles and makes of crossbars. Good stuff. I really like the straps that come with these, as there is a rubber cover that slips over the metal cam buckle to protect your car's paint while you're tossing the strap over your boats to strap everything in. In order to shuttle our boats for river trips, we needed stackers to fit on both our cars, so it was time for another set. I had never heard of Rhino Rack before, but the lower price than Thile caught my eye, so I read about them and decided to give them a try. The Rhino Rack Nautical Stack used a closed loop at the top, which I liked better than the Yakima or Malone options, and came with the hardware necessary to install them into the C-channel of my Malone aero crossbars, which I wanted to try. I remember that with the Malone stacker, you had to buy the C-channel mount hardware separately. I really like the Rhino Rack Nautical Stack. They are a single post design, unlike the loop style of the Thule "The Stacker". I don't know if this cuts down on vortex drag, but it definitely saves you a couple horizontal inches up where the boats stack. The Rhino Rack Nautical Stack has textured rubber strips on either side of the post, which I believe is intended to cut down on vortex drag, but is also quite helpful in that boats tend to slip much less when you're just leaning them up against the post as you load up before you strap them. That's smart. The Rhino Rack Nautical Stack feels really solid. The mechanism for folding them down and locking them upright is easy to use and feels solid. Installation instructions were good. I tried to install into the C-channels without removing the rubber tubing in my Malone aero crossbars, but couldn't get the little squares to slide into the slots with the rubber tubing in place, so had to cut the tubing, slide the Nautical Stacks into place, then cut down some of the tubing I had removed and replace it in the remaining unfilled crossbar slot. That's not a knock on the Nautical Stack; just a tip in case you're trying to do the same kind of install I did. The one area in which I was less impressed was the tie-down straps that come with this kit. The metal cam buckles have no covering at all, so I'll probably still use my old Yakima and Thule straps instead and use these as backups. But overall, I think these are going to work at least as well, if not better, than the Thule option, and for quite a bit less money.

My wife and I purchased the Rhino Rack Nautic Stack to transport 4 kayaks. We considered similar products by Yakima and Thule, but the acceptable weight limit for the Rhino Rack was there deciding factor. Each of our kayaks weighs 38lbs, and the Rhino Rack was the only item that could handle this load. We were very pleased with etrailer's service and advice. George was extremely helpful. I would highly recommend buying the hood anchors and an extra set of the down straps. The tire down straps are far superior to ratchet-type tie downs that you buy elsewhere - they are strong and SOOO easy to use. I highly recommend the Nautic Stack and etrailer. P.s. we use a bike lock for the Rhino Rack and for our kayaks and they work great for overnight theft protection when we take the kayaks out of town.
