I have a portable garage that cost around $160 and it works well. I have used it three years. It is 20' long and covers most of the boat. It keeps it dry and clean, if you get 90 inches of snow like we did last year it will have to be cleaned off after each snow which is fairly easy and you can keep it at your own home. I take it down in the summer so the UV doesn't destroy it. It takes less that 1 hour to assemble or disassemble and takes up very little storage space.By the way my boat is a 23.5 as well. Hope this helps.
