We used to do the same thing with our 35' mono when we kept it on a non tidal dock (with salt water
access). There was about 5 miles of fetch to the SE for winter
winds, so the boat
really got a workout during the storms.
The end of the dock was designed to face into the SE fetch.
We used conventional lines on the starboard side, and a single line to the mooring ball from the center chock on the port side. We had snubbers on the port line and both bow and stern lines on starboard.
This kept the boat about 4 to 5 feet away from the dock, and we didn't even need to use fenders.
