moderate speed
safe speed
half speed
bare steerageway
第9题:

is exempted

if you observe both sidelights of a vessel ahead for an extended period of time
All of the above
第17题:
four vessels are nearby
a vessel has a steady bearing at a constant range
there is any doubt that a risk of collision exists
a special circumstance situation is apparent

take avoiding action immediately upon determining that risk of collision exists
immediately sound the danger signal
take avoiding action only after providing the give-way vessel time to take action ,and determining that her action is not appropriate
hold course and speed until the point of extremis, and then sound the danger signal, taking whatever action will best avert collision
第19题:
such risk shall be deemed to exist
Such risk shall not be deemed to exist
