There's no sense spending any more time in the parking lot than you have to. The Groovy Landing Gear mounts to the hull and your wheels can stay, stow, or go depending on your needs. It also doesn't require you to flip your kayak to mount or unmount your wheels so that you can fish for fish (and not your gear)! With the kayak angler in mind, Boonedox has refined their product to include gear grooves on all sides of the receptacles as well as the center link bar, resulting in 70+ inches of track for attaching rod-holders, safety flags, lights, paddle clips, camera mounts, etc. This stronger, lighter, more-rugged design uses anodized aluminum and stainless-steel components to perform in the most strenuous of environments. The Landing Gear uses solid foam wheels, preventing the possibility of ever going flat. Optional Sand Tire Kit sold separately. Please note the Landing Gear is not intended to support the weight of a kayak during storage. Leaving the landing gear deployed during storage can cause flat spotting on the tires and add additional stress to your kayak. Rated for 180lbs.
