I would call that more “on” South Padre Island than “off” South Padre Island. I know, cheap comment but not much else to say. I’m just guessing here but as she is bow on to the beach it looks more like someone fell asleep and drove her ashore. If she was disabled and drifted ashore I would expect her to be beam to the seas... Off course that is just an internet observation. Maybe she was taking on water and was driven ashore to keep from going under.
