This is used to describe “upsetting a situation” – ie if you rock the boat it upsets the contents, lets water in, and possibly capsizes it. It is synonymous with causing aggravation or frustration.
I may not make any alternative suggestions, because I don’t want to rock the boat.
Example use of Rock the boat.
