Dry sailing
I take it you don't have a trailer for the Mariner. Anytime I wanted to do some dry sailing, I'd park my 222 next to my house on the trailer and get my mast up as though the boat was in the water. I still do this in the early spring and late fall. It makes it a lot easier to work on, or check out my rig to make sure that everything is OK. It just seems a lot easier and safer to put it on a trailer and bring it home to where your tools are more accessible, in the event that you'd like to do some modification, or work on her. There were times years ago, when I had to be near my phone for a whole week because of my job. So, I went in the boat sometimes and hung out with a cup of coffee and a magazine, or took a nap. I really don't know your circumstance, or whether you live on the water and have your own dock. They do sell Nylon straps that can take the weight of your boat. Two good size straps could do it, but I'd have two additional ropes connected to them, to keep the straps from sliding apart.
