A.by a tow line ahead of the vessel
B.forward on either bow of the vessel
C.approximately amidships of the vessel
D.on the vessel’s quarter
第2题:
towing line()
第3题:
Lower the()to the tug.
第4题:
only a stern light
a towing light above the stern light
two towing lights in a vertical line
two white lights in a vertical line
第5题:
The further forward and closer to amidships the more readily the tug will trip
Placement further aft permits more effective pulling,better steering and eliminates the danger of tripping
Installing the bitts down low lowers the center of gravity
The height and position of towing bitts has no significance

windlass
capstan
ball
moorings
第7题:
three masthead lights in a vertical line instead of either the forward or after masthead light
two masthead lights in a vertical line instead of either the forward or after masthead lights
two towing lights in a vertical line at the stern
a small white light aft of the funnel
第8题:
The catenary in a hawser should be sufficient so that the hawser just touches the bottom
The hawser is of sufficient length for towing when taut between tug and tow
Increasing speed usually increases the catenary in the hawser
Shortening the tow hawser generally decreases the maneuverability of the tug
第9题:
shorten the hawser or increase the tug's speed
lengthen the hawser or reduce the tug's speed
place your tug in irons
make a sharp turn
第10题:
to the base of the foremast
to the forward-most bitts
to the forward part of the deckhouse
at the stern
第11题:
shock loading on the tow line is reduce
towing speed is improved
the vessel is more visible from the tug
the catenary of the tow line is reduced
第12题:
It automatically maintains tow line tension
It prolongs the life of the hawser by distributing chafing as the hawser is paid out and taken in
As tension on the hawser increases,more line is taken in by the automatic towing engine
As tension on the hawser decreases,more line is taken in by the automatic towing engine
第13题:

three strand Turk's head
第16题:
acts as a reserve length of towing hawser when the tug applies more power,and it dampens the surge effect of the tow

is the dip in the towing hawser between the tug and the tow
All of the above
第17题:
towing line
slip line
breast line
spring line
第18题:
by a tow line ahead of the vessel
forward on either bow of the vessel
approximately amidships of the vessel
on the vessel's quarter
第19题:
increase the towing hawser's catenary and provide more spring
reduce catenary,allow operation in shallower water,and to release one barge without breaking up the entire tow
enable one tug and its crew without any outside assistance to make up or break down the tow
provide rapid delivery of logs from the northwestern United States to Hawaiian sawmills
第20题:
no fog signal
one short blast
one prolonged and three short blasts
one prolonged,one short,and one prolonged blast
第21题:
The towing line between the two vessels should be clear of the water
The towing line should be taut at all times between the vessels
There should be a catenary so the line dips into the water
None of the above
第22题:
two towing lights in a vertical line
a towing light in a vertical line above the sternlight
two towing lights in addition to the sternlight
a small white light in lieu of the sternlight
第23题:
start towing by pushing ahead
abandon the towing vessel
retrieve the tow bridle
relieve strain on the retrieving line
第24题:
all information contained on the barge's Certificate of Inspection
the condition of all towing gear to be used
all navigational aids to be used
