Fort Myers Beach has a good sized fleet of shrimpers which are

You can see their location, course and speed he

Look for the orange "boat shape" a little west of Captiva Island and
then click on it.

That's pretty neat!
I clicked on a ship in my area and it didn't show it's transit. What
determines that being displayed?

Also what determines whether a boat is actually displayed.
Never mind, I found the FAQ.

"Vessels appearing on the live map are equipped with an operational AIS
transponder and they sail within the reception range of an AIS receiver
installed on the land. "

Yes, the boat must have an operational AIS transponder and it needs to
be within range of a land based gateway station that receives and
uploads the data to the marinetraffic.com server. If you don't have a
gateway station in your area you might want to think about becoming
one. They will usually supply you with a free receiver/decoder and
any old marine VHF antenna you have laying around will serve.

There's one here, I'm on St. Andrews bay. As I write there are
five cargo ships, 2 Navy boats and a pleasure craft within a few miles.
I'll need to watch next time a tuna boat or shrimp boat goes out and
see if the have the AIS device.
