The Yakima ShowBoat 66 Slide-Out Load Assist Roller offers a significant assist when independently loading heavy, lengthy kayaks. Installation proved a bit challenging to get all things fully squared and sliding easily, but once accomplished, this item is a winner. 667679

  • Recommended Load Assist Options For Kayak Or Canoe Onto Roof Rack
    The Yakima ShowBoat 66 Slide-Out Load Assist Roller for Roof Mounted Kayak Carriers # Y04068 is a fit for your 2016 Honda CRV. It looks like most of our roof rack systems have a crossbar spread of 32 inches which would give you a roller extension range or 30 inches for up to a 50 lb kayak/canoe or 24 inches for 50-80 lb kayak/canoe. Another loading option if you have Aero Crossbars with the channel is the Side Rail Kayak Loader for Rhino-Rack Vortex Aero Crossbars # RRSLH01. Another...

  • Can Yakima ShowBoat Load Assist be Used with Rhino-Rack Roof Rack on 2012 Toyota Highlander
    The Yakima ShowBoat 66 # Y04068 is compatible with the Rhino-Rack Roof Rack # RRVA137B-2, # RRRLKVA, and # DK138 on your 2012 Toyota Highlander. To determine whether it is practical for your application I'll need you to take a few measurements. Your Rhino-Rack crossbars should be 31-1/2" apart on center so you need to use the middle set of rules for the ShowBoat 66 found in the attached document, boat weight within 35 lbs - 50 lbs and max roller extension at 30". As long as you don't...

  • Will the Yakima Showboat 66 Clear the Shark-Fin Antenna On a 2020 Subaru Outback Wagon
    I spoke with Yakima and can confirm the Yakima ShowBoat 66 Slide-Out Load Assist Roller part # Y04068 will work on a 2020 Subaru Outback Wagon. In order to make sure there are no issues with the rear shark-fin antenna you would simply want to position the roller to sit behind the antenna so there would be no contact. The mounting clamps can be flipped so you just want to make sure you have them positioned so the roller sits above the crossbar and not below. The width is adjustable so the...

  • Thule Aeroblade Edge Compatibility with Yakima ShowBoat 66 Slide Out Load Assist
    The Yakima ShowBoat 66 Slide-Out Load Assist Roller for Roof Mounted Kayak Carriers # Y04068 is compatible with the aero style crossbars of the Thule AeroBlade crossbars you mentioned.

  • Will Yakima ShowBoat 66 Slide-Out Assist Roller Fit Rhino-Rack Aero Crossbars on 2007 Toyota Matrix
    Yes, the Yakima ShowBoat 66 # Y04068 will mount onto the Rhino Rack Vortex Aero bar on your Toyota Matrix. We know this because the clamps on the Yakima Showboat 66 # Y04068 can hold crossbars up to 3-7/8 inches wide or 1-7/8 inches tall and the Rhino Rack Vortex bars measure 3-1/8 inches wide and 1-3/16 inches tall. I have linked the ShowBoat 66 to this page for you convenience.

  • Recommended Kayak Lift Assist For Roof Racks To Allow One Person Lifting And Loading
    My recommendation for getting your 14.9 Scupper Pro onto your roof rack is to use the Yakima ShowBoat 66 Slide-Out Load Assist Roller for Roof Mounted Kayak Carriers # Y04068. This will allow you to easily load your kayak from the ground onto your vehicle roof by yourself. It uses a roller similar to a boat trailer to roll the kayak up onto your crossbars. It includes the tie downs and is adjustable to fit most crossbar spreads. A side loading option to give you a pivot point is the...

  • Can the Yakima ShowBoat # Y04068 be Used on a 2015 Nissan Rogue with OEM Crossbars
    The Yakima ShowBoat # Y04068 can definitely be used to help load your kayak on your 2015 Nissan Rogue. Just be sure that you are using a saddle-type kayak carrier, like the Yakima SweetRoll # Y04074, and that they are within the 44-1/4" width of the rollers. Attached is a chart to help you get your roof rack ready for the ShowBoat.

  • Load Assist Kayak Carrier Recommendation for 2015 Ford Fusion with Inno Roof Rack
    For an assisted kayak carrier to use with the Inno roof rack part numbers # INB137, # INSUT, and # INK860 the best option is the Thule Hullavator part # TH898 which will fit the rack. This carrier lowers down to about waist height for when mounting the kayak into carrier that once installed you push up onto the roof of the vehicle which allows you a MUCH easier install than most kayak carriers.

  • Is Anything Else Needed with the HandRoll Kayak Carrier on a 2019 Subaru Outback Wagon
    The HandRoll Carrier # Y04082 that you referenced is actually just the part of the carrier that has the wheels. To complete the carrier you also need some saddles like the DeckHand # Y04083. This combination is available for your 2019 Subaru Outback Wagon in the kit # Y04083-04082 and is compatible with round, square, or aero-style crossbars. To add locks to either setup you need the 4 lock core set # Y07204. You can potentially also use the Yakima ShowBoat 66 Slide-Out Load Assist...

  • Bike and Kayak Carrier Options for a 2019 Subaru Crosstrek
    I contacted Yakima who instead recommended the Universal MightyMounts for Yakima Roof Mounted Accessories # Y03590 to fit your Mako saddles to the factory Aero bars on your 2019 Subaru Crosstrek. I also contacted Yakima regarding their ShowBoat 66 Slide-Out Rear Load Assist Kayak Carrier # Y04068 and they were confident this rack will provide clearance of your spoiler and will work for you. My recommendation is a side loading carrier as an attractive alternative for hatchbacks,...

  • Recommended Bike, Cargo, and Canoe Carriers for a 2017 Chevy Equinox with Factory Roof Rack
    For your 2017 Chevy Equinox I recommend using the Thule UpRide # TH599000 for your bikes because of how easy it is to use and you don't have to remove your front wheel to transport your bike. To carry your canoe I highly recommend the Lockrack Adjustable Watersport Carrier # 339-LRUNISETX for a few reasons. The first is that it can accommodate pretty much any boat style out there and the second reason is that this carrier has integrated locks that help grip your canoe and eliminate the...

  • Load Assist That Can be Used With Lockrack Watersport Carrier
    Though you can load your kayaks from the rear onto the Lockrack Watersport Carrier # 339LRUNISETA or # 339-LRUNISETX if you choose, the Yakima ShowBoat 66 Slide-Out Load Assist Roller # Y04068 won't work because its bars have a maximum spread of 32 inches, while the smallest the Lockrack assembly will be from outside to outside is 34 inches. There is an option for a rear-loading assist, the Thule Water Slide Non-Skid Loading Mat # TH854 which has a slick top layer to help you easily...

  • Does Thule Hullavator Need Crossbars to Extend 4 to 8 Inches on Jeep Wrangler
    I reached out to a representative of Thule who told me the Thule Hullavator Pro Kayak Carrier and Lift Assist # TH898 will require crossbars to extend at least 4 inches because the arms have some give, so when you put the kayak on it is likely to make contact with your Jeep Wrangler; additionally, they said is was unlikely to fit your Gobe Stealth Rack. Instead, the Yakima ShowBoat 66 Slide-Out Load Assist Roller for Roof Mounted Kayak Carriers # Y04068 could be a good option. It is...

  • Load Assist Kayak Carrier for 2018 Nissan Rogue with Factory Crossbars
    There are load assists you can use, but the Hullavator 897XT has been discontinued and I checked with Thule and the Thule Hullavator Pro Kayak Carrier # TH898 will not work with the factory crossbars on your 2018 Nissan Rogue. Instead, so long as your Rogue's factory crossbars are attached to raised side rails, I recommend checking out the Yakima ShowBoat 66 Slide-Out Load Assist Roller for Roof Mounted Kayak Carriers # Y04068, which is a rear-loading system. It will extend 34 inches...

  • Can the Thule Hullavator Pro be Used to Carry a Canoe
    The Thule Hullavator Pro # TH898 is actually only meant to carry kayaks. If you are looking for a canoe carrier from Thule then the only option is the Portage Canoe Carrier w/ Tie-Downs # TH819. This carrier clamps around your crossbars but if you have T-Slots you can use the Adapter # THXADAPT12 which can provide some security if you have locking crossbars. We do carry some other alternative options like the Inno Locker # INA446 and the Lockrack Adjustable Watersport Carrier # 339-LRUNISETX...

  • Assisted Kayak Carrier Recommendation for Roof of 2015 Subaru Outback with Factory Crossbars
    I checked with Yakima and the Sweet Roll part # Y04074 and the Showboat 66 part # Y04068 are both confirmed as a fit for the factory crossbars of your 2015 Subaru Outback. This setup is going to be your best solution. Assisted kayak carrier racks like this aren't cheap. To do it right unfortunately costs more than the more basic racks that require a bit more work like the part # TH834. For a factory crossbar application this is the best solution.

  • Recommendation for a Roof Rack and Kayak Carrier with Slide Out Roller for a 2002 Isuzu Axiom
    You will need the following items to install cross bars on the naked roof of your 2002 Isuzu Axiom. Yakima Q Towers Roof Rack Feet for Naked Roof, item # Y00124, two of the Q83 Q Clips for Yakima Q Towers, item # Y00683, and the Round 58 inch CrossBars for Yakima Roof Rack System, item # Y00409. Once you have the cross bars correctly installed you will be able to use the Yakima ShowBoat Slide-Out Roller for Roof Mounted Boat Carriers, item # Y04068, along with another set of cross bars....

  • 2 Kayak Carrier Options For A 2019 Toyota Highlander Factory Rack
    One key consideration here is if you have enough crossbar width on top of your 2019 Toyota Highlander factory crossbars to lay 2 kayaks side by side. Thule recommends 53 inches of crossbar width for example, which is well beyond what most factory rails provide. Yakima recommends new aftermarket crossbars for a scenario like this usually but said it's possible to use 2 sets of Yakima DeckHand Kayak Carriers with Tie-Downs # Y04083-2 on the same vehicle and use the Showboat # Y04068 to...

  • Is Malone Stinger Load Assist Compatible With Swagman Aero Carrier System
    I went out to the warehouse to check the mounting hole measurements of the Swagman Exo Aero Rooftop Kayak Carrier System with Tie-Downs part # S65145 compared to the Malone Stinger Load assist part # MPG350 and the Stinger would not properly attach to the bottom of the Swagman Kayak carrier. The Malone Stinger is designed for the Malone SeaWing carrier part # MPG107MD. The full kit is part # MPG113MD which comes with the load assist and tie downs. If you do not already have the Swagman...
