I think it is normally on the starboard side when it is mounted to the side, but most ribs have it mounted in the center so not to have weight distribution issues at high speed. If you are running at high speed and you weight is shifted to the starboard side, you will dig the starboard chine in and it can get unstable. You may need to add some trim tabs to offset this if you are going to run the boat at high speeds with an offcenter console you are going to drive behind.
