If you are the Master of a towing vessel whose only working radar no longer functions，what must you do?A.Notify the Captain of the Port (COTP) if you cannot repair it within 96 hoursB.Notify the Officer in Charge of Marine Inspection (OCMI) if you cannot

When the towing vessel enters the fog

When the drilling rig enters the fog

When the towing vessel can no longer be seen from the rig

Immediately

when a new Master assumes command

daily，at 0800 local zone time

weekly，before 2400 Saturday

immediately after assuming the watch

Notify the Captain of the Port (COTP) if you cannot repair it within 96 hours

Notify the Officer in Charge of Marine Inspection (OCMI) if you cannot repair it within 48 hours

Moor the vessel until it is repaired

Anchor the vessel until it is repaired

A vessel picking up a navigation mark

A vessel transferring cargo while underway

A vessel whose anchor is fouled

A vessel in a towing operation that restricts the ability of the vessel and her tow to change their course

The Master of the vessel must be on the bridge when the radar is in use

The radar equipment is only required to be used in restricted visibility

The use of a radar excuses a vessel from the need of a look-out

This equipment must be used to obtain early warning of risk of collision

to the base of the foremast

to the forward-most bitts

to the forward part of the deckhouse

at the stern

the masthead lights for a towing vessel

the lights for a vessel restricted in her ability to maneuver

sidelights，stern light，and towing light

All of the above

A vessel on the starboard bow whose bearing is changing and range is decreasing

A vessel on the starboard bow whose bearing is steady and range is increasing

A vessel on the port bow whose bearing is steady and range is decreasing

A vessel on the port bow whose bearing is changing to the left and range decreasing

Coast Guard approved

stamped with maximum working loads

positioned exactly at the bow of the towed vessel

a Coast Guard inspector

You must provide air transportation to the nearest port of entry in the United States

You must provide passage to the port of original engagement

There is no requirement for return to the United States provided the voyage has exceeded 4 weeks duration

The crew can be employed on another United States vessel，but only if it is returning to the port of original engagement

evaluate the danger of each closing visual or radar contact

adjust speed with due regard for the weather and visibility

reduce speed only where local speed limits are posted

enter all required test and inspection results in the vessel's log or other record carried on board

Your speed must be reduced to bare steerageway

A look-out is not required if the radar is on

Fog signals are only required when a vessel is detected by radar

The radar should always be kept on a short-range scale

vessel towing astern

barge pushed ahead

vessel towing astern only when the length of her tow exceeds 200 meters

this signal does not exist in international waters

can use radar information from one object to fix the position

should never use radar bearings

should only use radar bearings when the range exceeds the distance to the horizon

must use information from targets forward of the beam

not exceed bare steerageway during the transit

take a strain as soon as you can to control the tow

come up to speed very slowly and maintain a safe speed

come up to speed quickly，then cut back power considerably to ease the strain

Your speed must be reduced to bare steerage ways

A look-out is not required if the radar is on

The radar should always be kept on a short-range scale

Fog signals are only required when a vessel is detected by radar

You cannot update a view with group functions.

When you update a view group functions are automatically computed.

When you update a view only the constraints on the underlying table will be in effect.

When you update a view the constraints on the views always override the constraints on the underlying tables.

She must use this equipment to obtain early warning of risk of collision

The use of a radar excuses a vessel from the need of a look-out

The radar equipment is only required to be used in restricted visibility

The safe speed of such a vessel will likely be greater than that of vessels without radar

made only of wire rope，due to possible weather conditions

that will have the tow on a crest while your vessel is in a trough

that will have the tow on a crest while your vessel is on a crest

with little dip to gain maximum control of the tow
