The OS deckhand, or Ordinary Seaman, has always been the apprentice to the Able Seaman. Your other responsibilities will include cleaning and repairing deck equipment, the general maintenance, and cleaning of the deck department. You must also assist with the loading and unloading of equipment and supplies, as well as the storing of supplies or whatever else is needed at any time during a voyage. This position requires you to work at sea for a long period of time before you get promoted, and you have to complete a series of courses and certificates. Being a helmsman is one of the courses covered, so during your sea time, although not part of your duties, you should get experience in standing watch at the helm.
