I bought a cheap inflatable "dinghy" for our 23, from Dicks sporting goods - cost maybe 50 or 60. My use was to get a one person a short distance, maybe 150 feet, from the shore to our moored boat at a marina on a lake, so I did not have to use their rowboat and then have to return it to the dock. No big waves, no traveling from port to port, no carrying of gear or second person. On first test, the inflatable floor was way too soft to support me while standing to get on the swim platform. This is the cheap welded plastic, not Hypalon or anything like that, and can't be pumped up to high pressure (well, not without bursting it).
I made a wood floor for it, using some scrap 1/2 in planks. 1/4 probably would have worked. I used some of the pink foam panels that are used for home insulation to glue up (using polyurethane glue) a seat to insert on the floor and across the tubes.
That worked fine for my intended purpose. Keep in mind I was not cruising, so left the tender and floor and seat etc. on my mooring so did not have to worry about stowing it on the boat (though you could get clever and make some sort of a floor that could be knocked down into pieces).
I bought a 120v inflator, as the marina we used had an outlet near where I launched it, so that was always easy. Also bought a 12v model so if needed I could top it off using the boat 12v outlet.
If I were going from port to port and had to row longer distances to get from moorings to dock, and with waves, I would not have been happy with it, so it depends on how dava390 wants to use it.
