Engineers also need good eyesight but the entry requirements are lower . My advice is get your eyes checked at an opticians first . In general working at sea is classed among the most 10 dangerous jobs . Think on it before going any further . If the answer is yes , forget a life at sea .
Ships move , roll , pitch , yaw and everything in between .
Although regulations are coming into force to ensure adequate rest , there are times when sleep is a luxury you only crave . Whether it is due to the weather , ships motion , a hectic schedule or a breakdown , sleep is sometimes at a premium . If you really must have your 8 hours every night without fail forget the about going to sea for a career . Generally onboard ship you have to work a shift system . However at times you will be required to work outside those hours , normally for no extra compensation , it is all part of the job .
