Just another observation here from a recent "install." The one I mounted is the branded Native version and it appears identical in all ways to the Boonedox.
I had only seen a few mounted to Propel 10s and I was concerned about the width issue back there in the tankwell area, whether there was sufficient clearance for the wheels. So, I called Boonedox directly and talked to the right man, that is certain, as he knew all of the ins and outs, was familiar with my concerns. He said that he had just attended a large fishing tournament where quite a few of the Propel owners had track-installed units, and many were under pretty good gear loads. And, none were having any issues with the track version installation. Knock on wood!
So, this sort of installation does have the installer add the extra bolt to each side of the track to further increase the distribution of the load. Why a backing plate along the underside of the track, itself, wouldn't be another positive step is beyond me; but, now that I have used it a bit, the two knuckles and bar contraption are solid as a rock: no wiggle or visible flexing anywhere that I can see.
Just a guess that we may eventually see newer models of many kayak makes and models with specific mounting sites for these Landing Gears and for others that might be developed. One way to do this might be similar to the mounting plates available on the new Predator PDLs. If these were really anchored, made of strong material . . . and long enough, it'd give each kayaker a bit of control over where to mount them.
Anyway, assuming no misadventures with plastic pulling apart, this is the way to go as it certainly saves a whole lot of time getting on and off the water, on and off the back of a truck.
I did something I had never done before a few days ago. I went fishing in the AM, was awaiting a phone call that would pull me off the water, got it, but then no sooner than I got off, my wife called back with a change of plans. Hmm? If it had been 5 minutes earlier, I would have turned around and kept fishing. But, I went on home (close by) and ate lunch, took a short nap, then decided to go back out in the late afternoon so I did.
I'd never even consider doing this the "old way" but the Landing Gear made getting back on the water a second time, the same day, a snap.
I assume some of these posts are read by manufacturers. Question: Why aren't you moving faster to accommodate this obvious trend toward more functional carting on and off the water? If you are building really heavy kayaks (Hobie), wouldn't you sell more of them if it were easier to get on and off the water? Native? A lighter vessel, but why not beef up the plastic in critical spots? Predator PDL? Where is a hatch in the rear to give necessary access for these installations? Wilderness ATAK 120? And, on and on we go.
The first manufacturer to attend to this matter ought to have a big selling advantage.
