pgc. The helmsman was steering 303°pgc and 315° per standard magnetic compass at the time. Which of the following is TRUE?

16738: At 2212 your position is LAT 40° 51'N, LONG 71° 53.5'W.

What is the course to steer, per gyrocompass from your 2212 position, to leave Montauk Point Buoy "MP" abeam to port at 1 mile if easterly winds are causing 3° of leeway?

16739: What is the earliest time you should sight Montauk Point Light (nominal range - 24 miles) if you are turning for 9.2 knots? Visibility is 5 nautical miles.

16740: At 2245 visibility improves and Montauk Point Light bears 355°pgc. At 2314 Montauk Point Light bears 331°pgc, and at 2329 the light bears 311°pgc. Based on your 2329 running fix which statement is TRUE?

16741: At 2346 Montauk Point Light bears 285°pgc, and the radar range to Montauk Point is 5.9 miles. You are steering to make good 034°T. In order to remain westward of Southwest Ledge you should __________.

16743: At 0040 you are south of Lewis Point when you receive word that the distress is terminated. You alter course to head for The Race. At 0052 you take the following relative bearings because the starboard gyro repeater is inoperative. Your heading at each bearing was 285°pgc. What is your 0052 position?

Race Rock Light 002°
Watch Hill Light 034°
Block Island North Light 122°

16744: You continue to steer 285°pgc from your 0052 fix. Your speed is 9.2 knots. What is the course per standard magnetic compass?

16745: At 0100 Race Rock Light bears 001° relative, and at 0110 it bears 000° relative. Based on this you know you __________.

16746: In order to check your compasses, you sight Race Rock Light in line with New London Harbor Light bearing 336° per gyrocompass. The helmsman reports the vessel was heading 275.0°pgc and 290.5° per standard magnetic compass at the time of the observation. Which statement is TRUE?

16838: At 0800 you obtain the following Loran-C readings:

9960-X-27101
9960-Y-41612
9960-Z-58737

What is your vessel's position?

16839: At 0800 you reduce speed from sea speed. Speed was reduced by the time you passed abeam of Cape Charles Lighted Bell Buoy "12" at 0814. At this time Buoy "12" was abeam on your starboard side at a distance of 0.65 mile. Assuming you continue to make good your course of 202°T, what is your new speed if you pass abeam of Cape Charles Lighted Bell Buoy "14" at a distance of 1.5 miles at 0907?

16840: Visibility is exceptionally clear. At approximately what distance did Chesapeake Light become visible?

16841: At 0907 you change course to 224°T, and your speed is now 13.0 knots. At 0939 Chesapeake Light is bearing 168°T at a distance of 7.1 miles, and Cape Henry Light is bearing 246°T. What were the set and drift since 0907?

16842: From your 0939 position, you wish to change course in order to pass 0.3 mile north of Buoy "NCA" (LL#375) in the inbound traffic lane. You estimate the current to be 150°
T at 2.0 knots. What course should you steer to make good the desired course? Your speed is still 13.0 knots.

16843: At what time will you enter the inbound traffic lane with Buoy "NCA" (LL #375) bearing 180°T at 0.3 mile?

16845: After the pilot boards, he tells you the gyro has a 2°E error. If this is true, what should the bearing be along Trestle C of the Chesapeake Bay Bridge-Tunnel as your vessel passes abeam of it?

16846: Your vessel's heading is 330°pgc and 345°psc with a 2°E gyro error. What is the deviation on this heading?

20106: You are steaming at 22 knots and burning 319 barrels of fuel per day. You must decrease your consumption to 137 barrels per day. What must you reduce your speed to in order to burn this amount of fuel?

20107: You are steaming at 19 knots and burning 440 barrels of fuel per day. You must decrease your consumption to 137 barrels per day. What must you reduce your speed to in order to burn this amount of fuel?
