Geoff,
My boat was in decent shape and being a 1987 model, had many of the improvements that people install on their early C22 series boats.
I bought it last spring.
So far, I have spent as much on it, as it originally cost me.
I have above average DIY skills, and a shop full of tools.
I still haven't sailed it.
You live in Florida...
There are a bazillion boats that you can buy that will get you out on the water faster, and cost you LESS money to get there.
Especially so, since it's likely that the plywood that is encapsulated in the hull of that C22, is likely rotted in more places than just the mast step.
This is a friendly, supportive forum. The members here don't say these things lightly, nor do we say it to be mean.
Good luck with the quest.
P.S. If you do decide to go down the rabbit hole, and you enjoy spending more time working on a boat and spending money on it, than you do sailing, feel free to read the refit threads here, and ask for any help you need.
The knowledge you need is here, to get the boat sailing again, but doing so will have a large cost in both time and money. Even though the help and advice is free.
Who knows, maybe someone local to you, can come see the hull and see if that is, at least, not rotted internally.
