When I lived in
Fort Lauderdale, I would look at craigslist, which is where all of the classified ads migrated after the local newspapers crashed.
However, be aware that
renting a
dock is a tricky business in
Florida. In many communities, canals were dug so that developers could sell "waterfront" property to snowbirds.
You might find that a
dock is seven or eight miles from ocean access, on a
canal that is inaccessible at low tide or have two or three drawbridges between it and where you want to go.
You also have to examine how vulnerable the dock is to
boat wakes and during storms. Almost anything on the
ICW or a busy, wide
canal is asking for trouble.
I once rented a dock in
Fort Lauderdale that was perfect, right near Port Everglades, except that it was next to a fixed bridge and had a
current that could exceed three knots.
That made for some interesting launches and landings when the tide was flowing toward the bridge.
Another potential headache with
renting a private dock is that many homeowners want you to knock on their door and tell them when you're going to your
boat.
If you go out once or twice a month, no problem. If you're like me and sail two or three days a week, and maybe spend another afternoon on
maintenance, the homeowner is going to get tired of you very quickly.
For those reasons, I keep my boat at a marina these days, even though it costs more.
