Unit 2 test

1.Entering a US harbour from seaward, a green can buoy should be left:

2.After 3 hours the fix lies 6 NM at 270° from the DR position. Set and drift are:

3.A light showing VQ(9) every 10 s with black bands top and bottom over yellow indicates:

4.Steering 090° at 10 kn with a set of 180° drift 2 kn, the vessel's ground track is:

5.A running fix is less reliable than a simultaneous fix because it:

6.Which symbol denotes an estimated position?

7.Compass course 125°, deviation 3°W, variation 12°E. The true course is:

8.Nominal range of a light assumes:

9.Spring tides occur:

10.The most accurate line of position available in piloting is usually:

11.Low water 1.0 m, high water 5.0 m, six-hour rise. Using the Rule of Twelfths, the height three hours after low water is:

12.Charted depth is 4.2 m and height of tide is 1.6 m. A vessel drawing 5.0 m has an under-keel clearance of:

13.True course 270°, variation 8°W, deviation 2°E. Compass course is:

14.Deviation differs from variation in that deviation:

15.A danger bearing is used to:
