What do you do if you are travelling in Indonesia by ferry? Never get on a ferry that looks dangerously overloaded. Never get on a ferry heading into a big storm, try travelling during the day as rescue will be easier, if the ship sinks. Do not sleep in a cabin, sleep on the rear deck so you can get out in a capsize situation. Bring your own means of floatation, as there will not be enough life jackets. As I mentioned before, a large kid’s inflatable rubber ring, is better than nothing, and might keep you afloat long enough for a fishing boat to find you.
