I can tell you the third time I had my RL out, and my families first sail, we had winds in the high teens, peaking probably 25 mph. It was really not a big deal. We only had the main up, and eventually reefed. At no point did I have any concern about the boat and its ability to handle the conditions. The boat is fast. Speed reduces the load on the sail. When the boat does finally heel, there is plenty of warning, even enough warning for me to wait for the dirty look from the wife, before reaching down and spilling the main. So as far as wind goes, while some claim the boat is tender, I do not know any better, so I think it does very well.
Now I do need to qualify my statements. When I was out in those conditions, this was on a 20k acre lake, which does not get huge waves. Yes, there were some, but nothing big. We did get a little wet sometimes, but that is part of the fun.
In the land of OZ, most are sailing coastal, so they are out in the ocean. There are very few inland lakes. If you search on "out through the southport bar RL 24" you can watch a youtube video of a guy motorsailing through rough water.
Since it will float in less than a foot of water, launching is easy. Setup takes about 35 minutes or a little more if you are lazy. The key is to prepare the boat for easy setup. I've added some extra u-bolts on the cabin top to stabilize the mast when stepping. Everything is on caribbeeners, so it sets up fast.
As far as depth finder, the place where I normally sail, I usually hit bottom at least once every time I go out. The average depth is 5 feet. Either you turn, or reach into the cabin and give a couple of cranks on the centerboard. Its a swing keel, so hitting bottom is uneventful.
Here we are in some wind:
