More than likely what you are seeing is the air conditioning running. They are water cooled units and they have to circulate water when in A/C or heat mode.

That would be my guess. A bilge pump that runs on a docked boat would worry me quite a bit. My slip neighbor's bilge pump was running every hour or so so I called him on the telephone. He came to the marina and found and fixed a leak. We watch out for each other that way.
