Not only is all of this confusing but I think it is rather stupid and possibly compromises safety. Don't take this as an attack against you but against whatever governing board is responsible for this. The wake plate is and can be used to decrease the wake size if used properly. As for the ballast, just don't fill them, deactivate the pumps and call it a day. If the pump is deactivated and cannot fill the bags, no problem there. Just placard the pumps as INOP and call it a day.
