Offshore boating jobs exist for crew and captains who work aboard boats and ships out at sea. When you work on an offshore boat, you perform your duties according to your ship captain’s orders. These positions exist onboard both cargo and transport vessels and smaller passenger cruise ships, but you can also find jobs on a craft servicing rigs in the oil and gas industry. Some of the positions available include first, second, and third mate, cargo mate, roustabout, welder, mechanic, drilling technician, derrickhand, deckhand, electrician, and more. Often, your responsibilities mean you follow a strict rotation, such as 28 days on with 14 days off or even 28 days on with 28 days off depending on the route and schedule.
