i stopped at Utsch this time around, it's fine. friendly folks, goody bag with a bottle of wine. Only thing about Utsch is that it's a little tight with a larger boat, I barely had enough room to turn around in the fairway (with a 70 footer) and the area between the canal channel and the marina entrance gets a little shallow if you stray too far from their dock.
in the spring on the way up i had stopped at Miss Chris Marina which was a little rustic but equally friendly. Restaurants nearby, the guy have us some fresh fish just off the charter boat...
The canal is easy to navigate, watch for the ferries and dont' try to pass them as they come in and out, the water is very shallow on the south side across from the terminal.
