To have status as a seaman, a person can be a member of the crew working on fishing vessels, lay barges, crew boats, supply boats, tugs, towboats, semi-submersibles, jack-up rigs, freighters or tankers. Crew members, officers and captains are all seamen, and employees on movable or jack-up drilling rigs have seamen classifications as well. Pilots, longshoremen and people working on fixed platforms usually do not have the status of seamen, but other maritime remedies may be available for them.
