For Qualified Ratings, you must submit proof of required service based on days you worked at sea while underway. A day is defined as eight hours of watchstanding or day work, not to include overtime. On commercial vessels where a twelve-hour workday is authorized and practiced, such as on a six-on, six-off watch schedule, each workday may be considered for one and one-half days of service credit. Required sea service is specified in months or years, which are then converted to days, i.e., one year means 360 days and one month is 30 days. You may document required service in various forms, including original certificates of discharge and/or official documents from marine companies on original company letterhead signed by authorized officials. Your original proof of service MUST INCLUDE the following information about the amount and nature of your experience:

1. Name and documentation/official number of each vessel on which the service was obtained
2. Vessel's gross tonnage, shaft horsepower and type of propulsion
3. Number of days underway on each vessel including the dates the service was obtained
4. Number of days spent in each type of route (Ocean, Near Coastal, Inland, specific river or lake, etc.)
5. Average number of hours worked per day
6. A brief description of duties or work performed.
