I have a question about long ocean voyage in a powered boat.? - power boating course

I saw a 55-foot catamaran powered on the Internet. The owner intends to examine cruises. She plans to go with his wife alone. My question is, over long distances over 48 hours, what is the normal procedure? Do you think that the engine shut off and driving at night? Would you agree that the autopilot hold it overnight? "It's a boat teams of two days of the trip?
