359a: Your current location is midway between Buoys "37" and "38"
at the North entrance of York Split Channel.
You are turning for 9 knots, a westerly wind is causing 3ø
of leeway, and the current is 320ø T at 1.2 knots. What
course should you steer to remain in the northern leg
of York Spit Channel?
15110a: From your 1752 position, you steer 180ø psc at 9 knots. At
1805, you obtain the visual bearings. What are the
latitude and longitude of your 1805 position?
Old Pt. Comfort Light 242ø psc.
Chesapeake Bay Tunnel North Light 140ø psc.
A: 211ø psc
B: 205ø psc
C: 202ø psc
D: 199ø psc
15117: At 1930, you take a fix using the following radar ranges:
York Spit Light - 3.6 miles;
New Point Comfort Spit Light "2" - 2.0 miles;
York Spit Swash Channel Light "3" - 2.5 miles.
Your longitude is _____________.
A: LAT 37ø06.1' N, LONG 76ø08.1' W
B: LAT 37ø06.0' N, LONG 76ø08.4' W
C: LAT 37ø05.9' N, LONG 76ø07.7' W
D: LAT 37ø05.9' N, LONG 76ø08.0' W
15310: Which chart could you use for greater detail of the area at
the south end of York Spit Channel?
A: 76ø16.5' W
B: 76ø16.8' W
C: 76ø17.0' W
D: 76ø17.2' W
15407a: At 1430, your position is LAT 37ø12.8' N, LONG 76ø17.7' W.
At this time, you come left and steer 057ø psc. This course
will lead you through a channel bordered by yellow buoys.
The dashed magenta lines between the buoys mark ___________.
15414a: At 2100, you have passed through the Chesapeake Bay Bridge
and Tunnel and determine your position to be LAT 37ø01.3'
N, LONG 76ø03.0' W. The current is flooding in a direction
of 303ø T at 2.5 knots. Adjusting your course for set and
drift, which course would you steer while turning RPMs for
6 knots to make good a course of 175ø T?
A: York River Entrance Channel
B: New Point Comfort shoal area
C: the piloting channel for Mobjack Bay
D: fish trap areas
15439-15440a: You arrive at Chesapeake Bay Entrance Buoy "CB" at
the entrance to the inbound lane of the traffic separation
scheme at 2058. Your ETA at Chesapeake Bay Bridge and Tunnel between
trestles B + C is 2300. If your engine speed is 9.8 knots,
what will be your approximate speed over the ground, at
that time, allowing for the predicted current?
A: 164ø psc
B: 172ø psc
C: 191ø psc
D: 198ø psc
15459a: At 0823, while holding a true course of North,
Old Point Comfort Light bears 012ø psc at 0.6 mile.
What is your 0823 position?
A: 7.0 knots
B: 8.2 knots
C: 11.4 knots
D: 12.7 knots
15612: At 1920, Cape Henry Light bears 225ø pgc, and Chesapeake
Channel Tunnel North Light bears 288ø pgc. If your heading
is 268ø T, what is the relative bearing of Chesapeake Light? (assume dev = 0 ??)
A: LAT 36ø59.5' N, LONG 76ø18.4' W
B: LAT 36ø59.0' N, LONG 76ø21.6' W
C: LAT 36ø59.0' N, LONG 76ø19.6' W
D: LAT 36ø55.5' N, LONG 76ø18.6' W
15161a: From your 1815 position (37ø 01.1', 75ø 42.7'),
you want to make good course 275ø
psc. Your engines are turning RPMs for 12 knots. The
current is 050ø T at 1.9 knots. Adjusting your course for
set and drift, at what time should you expect to enter the
red sector of Cape Henry Light?
