There are a couple of options. There is an aftermarket swing part that is made by Fulton. It is not as durable, though works alright. This could be installed. You could have a local fab. shop do a pivot for you if your talking used boats. On a new rig you have more options. For Example, drop back tongue to get the last 3″ back, narrow frame for narrow doors, though not being able to go less than the 94″ boat width. Then the standard pivots tongue, plus you can go to a 3″ plate for the engine clearing more. BCB
