- U.S. mariners pursuing OUPV or Master credentials
- Worth noticing
- Its sample log credits 4.5 hours split across one day, but caps a 12-hour trip at one sea day.
Field notes
The worked log demonstrates how the counter handles edge cases: less than four hours on a qualifying small vessel does not count, separate trips on one boat can add up for a day, and hours on multiple boats count only once for that date. The progress example also separates total service from near-coastal or ocean days and recency, with regulation or policy citations shown beside the figures.
