Not sure it is the same, but back in the olden days, there was a section in the Marine Engineer's Sea Project that included Deck Department subjects. I recall taking sights with my deck cadet partner, describing mooring arrangements. . .and some others. Most of your time, however will be dedicated to the Engine Department, and working as directed. Frankly, I took on quite a bit during my Sea Year, and it paid off nicely once I started sailing on my license. Take advantage of any opportunity offered during Sea Year, even those nasty bilge crawling jobs.
