I've docked a boat there, but I have visited a boat while it was in a slip there. The surge caused it to be difficult to board and/or disembark the boat. I was glad I was sober! I think if one were tipsy, seasickness might ensue. Or, worse, one might fall overboard. I had to carefully time my stepping on/off with the surging.
While I was visiting on the boat, I enjoyed the added motion on the boat. But that is just me!
