Who must be tested for drugs? - ANSWER-Master, operator,
navigator, lookout, deckhand who handles lines
Negative test results must be kept for ______ year. Positive test
results must be kept on file for __________ years. - ANSWER-
One, Five
_______________ is the upward force of water displaced by the
hull. - ANSWER-The buoyancy
__________________is affected by movement of the center of
gravity or center of buoyancy or by some outside forces, such as
wind and waves. - ANSWER-Equilibrium
_____________________ stability tends to keep the vessel from
rolling over (capsizing). Additional weight above the center of
, Page |2
gravity increases the distance from the center of gravity up to the
center of buoyancy. As a result, stability is also decreased.
Removal of weight from below the center of gravity also
decreases stability. If the center of gravity is raised enough, the
vessel will become unstable. - ANSWER-Transverse (athwart
ships)
_____________________forces are caused by actions outside
the hull such as wind and waves. - ANSWER-DYNAMIC
________________forces are caused by placement of weight
within the hull. Adding weight on one side of a vessel's centerline
or above its center of gravity usually reduces stability. Flooding or
grounding a vessel makes it susceptible to static forces which
may adversely affect stability. - ANSWER-STATIC
Damage to the hull of a vessel can create
____________________________ with the sea, permitting the
movement of sea water into and out of the vessel.
___________________________________ also has a negative
effect on stability. - ANSWER-Free communication

___________________to Navigation indicate which side of an aid
to navigation a vessel should pass when entering from seaward. -
ANSWER-Lateral Aids
Red colored aids are ____________ numbered. - ANSWER-Even
Green colored aids are_________numbered. - ANSWER-Odd
Only aids to navigation with __________or ____________ lights
have lateral significance. - ANSWER-green or red
This Light List is published via HARDCOPY ______________
(how often?), and posted electronically - ANSWER-annually
____________ is caused by the earth's magnetic field. -
ANSWER-Variation
__________________ is the magnetic compass error caused by
magnetic influences on the vessel. - ANSWER-Deviation

Changes to aids to navigation during the year are published in
U.S. Coast Guard Local Notices to Mariners _____________
(how often?). - ANSWER-Weekly
________________ is the distance you will see a light if you have
10 mile visibility. - ANSWER-Nominal Light Range
________________ is the maximum distance at which a light may
be seen in perfect visibility by an observer at sea level. -
ANSWER-Geographic Range
_________________ is the geographic range PLUS the
observer's distance to the horizon based on the observer's height
of eye. - ANSWER-Computed
___________________ is the maximum distance at which a light
may be seen under the existing meteorological visibility
conditions. (Which is defined as meteorological visibility of 10
nautical miles). - ANSWER-Nominal Range
