I like this guy.
Caz, when I was between wives, I lived aboard a 35' Chris-Craft Sea Skiff. It floated, mostly, the engines ran, somewhat, the slip was paid for for the first season, and it was cheaper than first and last on an apartment, but still cost almost all the cash I had at the time.
I didn't regret it then, and I don't regret it now.

The upside to being broke in a marina is that at least you are broke in a nice neighbourhood. Being broke on land means living in a neighbourhood where everybody else is broke too, and that can, and will, kill one's spirit real quick.
Before you go boat shopping, print out the "Inspection Trip Tips" sticky, and don't be afraid to get dirty. Pull the floor boards to see the bilge, pump the head, do a visual on the engine and the transmission dipstick, and poke, prod, and peer into every nook and cranny and part.
