I tested this by placing all available fuel from my inventory to a chest, drove away, and I was unable to do anything due to the ship having no fuel (thankfully i was able to recover with landfill bridging that gap between the chest). I think there should be a way for the player to recover from this at a cost of an extremely low speed with the boat (mimicking people rowing oars manually), similar to dead robots when they are reaching a roboport.
