Based on the total respondent pool of 4,046 (with a sampling error of about ±2% at the 95% confidence level), the following generalizations can be made for the target population of 104,170 merchant mariners:
- About two-thirds (66%) of all mariners report they are willing to perform sea duty during times of national emergency.
- About two-thirds (68%) of all mariners were employed either full- or part-time in an afloat position during 2000.
- The majority of UL Holders (79%) and about half (47%) of Other Mariners attended a maritime training school in order to meet part or all of the requirements for obtaining a U.S. Coast Guard license or merchant mariners document.
- At the time of the survey, 45% of UL Holders and 29% of Other Mariners held an STCW-95 certificate. However, for mariners working in a deep-sea position at the time of the survey, 65% of UL Holders and 53% of Other Mariners held certificates.
- About half (49%) of all mariners indicated that reemployment rights could make it more likely that they would serve in a national emergency.
- About half (53%) of all mariners with documents appropriate for deep-sea service could be reached by using the information in the MMLD if the database is routinely updated based on postal system files and both mail and phone contacts are attempted.
