I was reviewing this thread this morning before taking my final test, which was Nav Problems NC for 1600 mate. Thought I should give a trip report for some future young sailor. Sorry, I can only remember 8 of the questions off the top of my head! If I recall the others, I’ll edit this post for posterity. I took all 6 modules this week at REC Oakland, which was really a pretty pleasant experience. Everyone there was incredibly helpful and thoughtful.
- question asking for best time for clearance of 2 feet over a rock that you’ll be over in 1h40m. Daylight savings time to boot.
- period <0.3 knots around first afternoon slack. DST again. Table 4.
- compass correction by amplitude on visible horizon
- engine slip
- CMG accounting for set and drift. I was scored wrong on this one, but am 100% sure I got it right. I was in a hurry so I didn’t fill out a comment card. Wish I had.
- distance off abeam a light using Table 7 - not a special case
- compass correction asking for deviation at a particular heading pgc. Required doing two separate CDMVTEG jobs and a simple interpolation. Easy enough, but hadn’t seen this particular question stem before. Kind of a fun problem to do, actually.
- CTS accounting for leeway
Overall, really on the easier end, considering some of the wackier questions that are in the pool according to Murphy books and LAPware–both of which I worked through over and over for the past 6 months.
Additionally, I found a wrong answer on my chart plot portion (Long Island Sound). The question asked for depth of water given an exact lat/long. Super easy, and my fix was square over a 108’ sounding on the chart, and 108 was an answer choice. I read and re-read that question several times, and it was not asking for DBK. I’ve been nav officer on my (government) ship for years, am very confident with my plotting skills, and took the fix 3 times. I’m dead certain I’m correct. Even with getting that one wrong, I didn’t fail, so I didn’t challenge it officially. I did show it to the examiner, who said she would follow up with NMC.
