About This Test
This course is for anyone who prepares for the U.S. Coast Guard Able Seafarer (AB) rating. It follows the exam subjects in 46 CFR 12.405: nautical terms, the compass, running lights, passing, fog and distress signals, helm orders and bridge to engine room communication, pollution rules and discharge procedures, and lifesaving and fire duties.
The mock test follows the real exam: two written modules of 50 questions, each passed at 70 percent (35 correct), with 3.5 hours for each. Q450 covers Navigation General and the Rules of the Road; Q451 covers Deck General and Safety. You show knots, bends, splices and hitches by making them for the examiner, so this course does not test them.
You take the real exam at a Coast Guard Regional Exam Center or through an approved course.
This course drills 198 questions.
