If you're lucky, road runner and foxes have inside spots where you don't get slammed into the dock or shoved under. Road runner has a beach area too.
Pirates has docks in their lagoon behind the restaurant and off the main river as well.
Other than that, not many dock places. Sandbar across from Sundance, sandbar in the cove across from Blue Water, and cove past Buckskin with a beach. Other option is try to get an anchor to bite and just anchor bow out where ever you want.
