ChrisJ, could you translate what "wooden sleeper" means? Your idea has fired off a few more design ideas, but not sure what you meant. Also, everyone, if you leave the amas on and in the extended position and just leave the AI parked on the grass, wouldn't the amas (or at least the one that it's leaning on) be enough to 'spread the load'. Then you could just tarp it to keep debris out. What are the problems with that?
I was just thinking of something that was stable and would support the sort of kayak saddles they use on roof racks. Now I think of it some more, how about four heavy wooden blocks supporting 1" square profile tubular steel rods, like they use for heavy duty roof racks? I'm pretty sure Thule has saddles to fit that arrangement.
As to leaving it on the ground with the amas extended, I would have thought the ama the boat was leaning on would have minimal effect in reducing the load on the hull, while the weight of the opposite ama would actually increase it. The problem is that at the points where the hull contacts the ground, the pressure can be considerable if the contact isn't spread over a wide area. As Yakaholic mentioned, bedding the hull into soft sand seems to work for spreading the load. I've found that too and have even slept on the boat on soft sand. Unfortunately, that is a luxury you probably don't have. Also, if you are using a trolley to wheel the boat up to its resting place, how are you going to get it back in when you want to launch?
