If your boat has an engine, fuel, fuel tanks, propane, waste, or waste tanks you are clearly in violation of MARPOL if you scuttle your vessel. And that's ignoring the large piece of plastic we call a hull.
Why would you do it? To eliminate a navigation hazard? A yacht isn't much of a hazard. If a ship hits it they probably won't even notice. If a yacht hits it they might do some damage but they probably won't sink. And they should have been standing watch anyway.
