OUPV 6 Pack UPDATED ACTUAL Exam
Questions and CORRECT Answers
1 Part per million is oil pollution - CORRECT ANSWER -
Low Pressure - CORRECT ANSWER - Air rises near low pressure areas. As air rises, it
cools and often condenses
What is piloting? - CORRECT ANSWER - Piloting is the movement of a vessel by
referring to landmarks, aids to navigation, depth sounding and radio navigation.
What is dead reckoning? - CORRECT ANSWER - The process of navigating by
advancing a known position using course, speed, time and distance to be traveled. In other
words, figuring out where you will be at a certain time if you hold speed, time and course you
plan to travel.
DR Plot (Dead reckoning plot) - CORRECT ANSWER - A DR plot should be maintained
at all times. It is the best estimate of where the vessel should be at any given time.
Latitude and Longitude - CORRECT ANSWER - Marine navigation is based on a system
of geographic coordinates that are used to describe a specific location on a body of water. The
best known system and most widely used set of coordinates is latitude and longitude system.
Nautical mile - CORRECT ANSWER - equals approximately 2000 yards or 1.15 statute
miles.
Distance on nautical charts is measured by? - CORRECT ANSWER - We use ONLY
latitude to measure distance on nautical charts.
True North - CORRECT ANSWER - Is different from magnetic north. The difference
between them is called Variation.
,Mercator projection - CORRECT ANSWER - The type of projection most widely used in
coastal navigation.
1 Min of latitude is equal to 1 mile everywhere - CORRECT ANSWER - LATITUDE
SCALE ONLY that is used for measuring distance.
Compass card - CORRECT ANSWER - Remains stationary and the vessel turns around
the compass card.
Lubber Line - CORRECT ANSWER - The Lubber's line is a line or mark scribed on the
compass card housing to indicate the direction in which the boat is heading.
Variation - CORRECT ANSWER - The difference between true north and magnetic north.
On nautical charts, the variation for a given area is noted at the center of the compass Rose. -
CORRECT ANSWER -
What is Deviation? - CORRECT ANSWER - The compass error caused by magnetic
forces within the vessel, such as electronic equipment and ferrous metal objects.
The sum of variation and deviation are called? - CORRECT ANSWER - Compass error
National Ocean Service - CORRECT ANSWER - Part of NOAA and responsible for
preparing nautical charts
Mercator Chart - CORRECT ANSWER - Mercator chart projection is the most widely
used projection is marine navigation.
, Small scale-Large Scale - CORRECT ANSWER - Small scale charts show a large area.
Large scale chart shows a small area.
All heights given in feet above mean high water unless otherwise stated. - CORRECT
ANSWER -
Vertical roman lettering used to table all conspicuous information that is not affected by the tidal
changes or current. - CORRECT ANSWER -
A dotted line around any symbol calls special attention to its hazardous nature. - CORRECT
ANSWER -
Coast Guards local notice to mariners - CORRECT ANSWER - Charts are corrected using
information provided in the Coast Guard's local notice to mariners. They are published weekly
by geographic region.
Mariners are first warned by a marine broadcast local notice to mariners. - CORRECT
ANSWER -
The dead reckoning (DR) track is the path or course the vessel is expected to follow. It is plotted
from a known position using courses and speeds through water. - CORRECT ANSWER -
USCG light list - CORRECT ANSWER - Published in seven volumes and contains lights
and other aids to navigation. This publication and the data contained within it is maintained and
published by the coast guard.
The National Ocean Service (NOS) - CORRECT ANSWER - Is part of NOAA and is
responsible for surveying the coast, harbors, and tidal estuaries of the U.S. and it's possessions.
One of their publications is the Coast Pilot.
