I would opt for a lower profile kayak rack if I only needed to carry one kayak.
Had to retrofit axle with screws so straps and bungee cords would not rub against the wheels.
Would not recommend. Sold it at a loss.
Only feature I do not like about the kayak is the neoprene cover on the hatch. It is impossible to put on. Even the sales rep could not get it on without my help. I cut my own rubber gasket and glued it to the inside of the hatch and do not use the neoprene cover.
Necky needs to address this issue and redesign.
