three-fourths the SWL of the main towing hawser
that of the main towing hawser
twice that of the main towing hawser
第5题:
it is overtaken by the tow
it is pulled sideways by the tow

with little dip to gain maximum control of the tow
第11题:
pushed ahead
towed alongside
towed astern
Any of the above
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:
the weight of its tow,its being anchored,or grounded
the weight of its towing hawser on the bottom
an adverse current
lack of power or an engine breakdown
第14题:
Serves as a backup for the main tow hawser in case of failure
Provides weight and flexibility to the total tow makeup
Lengthens the main tow hawser to keep the tow in step
Distributes the towing load
第15题:
acts as a reserve length of towing hawser when the tug applies more power,and it dampens the surge effect of the tow
gives an approximation of the amount of strain on the towing hawser
is the dip in the towing hawser between the tug and the tow
All of the above
第16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
