I had an F9AX for a few years and kept it in a small marina where there was no room to "swing a cat".
For a few months I was allocated a slip that was so narrow, that although wide enough to accomodate the opened up boat, getting to fit in was so tight I had to fold one side to berth the boat. Once berthed I could open the boat again but with the fenders on both sides pushing hard agains the docks on either side.
Anyway, I singlehanded the boat most of the time I went sailing. I found I could easily enter the little harbour and once inside stop the boat and just let it be. While drifting I would quickly undo the cap shroud
and the two bolts on the float to be folded. Then fold the one side and dock
the boat. It requires a bit of a grunt to fold the float on the F9 by yourself, but no big deal.
What also works well in a small space and if only tying up for a short overnight stay. is to fold the one side only. (fold the side which is away from the dock).
Even folded the boat was easy to steer. Most important is to always have the dagger board right down.
Have fun, these boats are great.
