Roof Rack and Kayak Carrier for Truck Cap to Carry Heavy Kayak or Canoe

Question:

Hi, the Thule site for the Hull-a-Port XT states it has a weight capacity of 130lbs for 2 kayaks. How is that justified if it can only support 75 lbs for 1 kayak? Is it possible for the Hull-a-Port XT to hold a kayak heavier than 75 lbs if its in the upright position? What if I also have a Hullavator Pro installed and lean the Hull-a-Port XT upright against the Hullavator Pro? Thanks! Ive been spending a lot of time on your site and its helped me better work out the parts I need to carry 2 kayaks on an A.R.E. truck cap Im planning to purchase. My wish is to move a Thule Hullavator Pro from my other car to the cap and at separate times carry a different 90 lb kayak beside where the Hullavator is installed. It exceeds the load capacity of the Hullavator and cant be used for this kayak. What Ive worked out is this. Rather than have the manufacturer install a Yakima track, Im thinking of purchasing a Rhino-Rack Roof Rack System for the cap. The thought is the Yakima track is made of aluminum and the Rhino-Rack is made of stainless steel and seems to be better constructed. Im looking at different options for the 90lb kayak / canoe hybrid, such as the Thule Portage, Yakima Keelover or possibly the Rhino-Rack J-Style Kayak Carrier. I do have some questions: 1. Looking at the systems, what are the differences between the Y02-500B and Y02-500B-ST? 2. Each uses the Vortex Aero Crossbars and have weight capacities of 220 lbs, yet the RRVA165B-2 Vortex Aero Crossbars are only rated for a weight capacity of 165 lbs. Do you know why this is? 3. Would you please tell me whether my reasoning and choice of products is reasonable? I do intend to purchase the items from you once I receive the cap and determined the actual widths of the crossbars I need for the Hullavator. Thank you!

To answer your first question the Thule Hull-a-Port XT Kayak Carrier # TH848 has a 75 lb capacity for a single kayak and 130 capacity for a pair of kayaks because as you can see in the accompanying photo, the Hull-a-Port XT has one kayak inside its cradle and the other resting up against it, which means it can only support a portion of that kayak's weight and leaning it up against your Hullavator Pro # TH898 would not change that (nor would I recommend doing that). If you do decide to go wtih the Hull-a-Port you can get it and the Hullavator keyed alike by installing the Thule One-Key System Lock Cylinders - Qty 4 # TH450400.

As for the Rhino-Rack Roof Rack Systems, the difference is pretty simple: part # Y02-500B comes with 1-3/8" bolts while part # Y02-500B-ST comes with 2" bolts and is made to accommodate thicker surfaces, so you would need to know the thickness of your A.R.E. truck cap in order to get the rack with the bolts that are the proper length. The reason for the difference in capacities is that these are entire roof rack systems as opposed to single bars; also note that this capacity is for loads evenly distributed over the rack. You should also ensure that your truck cap has the capacity to haul your kayaks as it may have a load rating which is less than that of this rack.

To carry your heavy kayak/canoe I recommend the Thule Portage # TH819 because it has a padded base that protects your kayak and is designed to be easy to use; after you load your kayak or canoe, just tighten the Portage's hand knobs. This carrier has a 150 lb capacity, comes with tie downs and even has a lifetime warranty.

I've added a link to a video review of this carrier for you to check out as well.
