Workers in water transportation occupations usually work for long periods on small and cramped ships, which can be uncomfortable. Many people decide life at sea is not for them because of difficult conditions onboard ships and long periods away from home. However, companies have worked hard to improve living conditions on their ships. Most ships are now air-conditioned and include comfortable living quarters. Many ships also include entertainment systems with satellite TV and Internet connections. Large ships usually have a full-time cook, as well.
