While the captain is responsible for the ultimate decision making, you are in essence the co-captain. The general navigation, maneuvering, and safety procedures of the cruise ship, such as a Scylla river cruise, would be led under you. If you have the desire to one day be the captain yourself and you have prior experience assisting a captain aboard a river cruise ship, then this job is made especially for you. In addition, this position will entail an attention to the maintenance, cleaning and overall orderliness of the vessel’s deck.
