Fresh water may be obtained from fish

lifeboat covers or canopies should be washed with rain before drinking water is collected

Fresh water may be collected from condensation inside the life-raft

Freshwater cannot be produced from standing seawater

While the ship is at sea，there must be available at all times a supply of electrical energy sufficient to operate the radio installations and to charge any batteries used as part of a reserve source of energy

Both the VHF and MF/HF installations must be simultaneously supplied

A means of ensuring a continuous supply of electrical power must be provided to all GMDSS equipment that could be affected by an interruption in power

If a UPS or equivalent is used to supply power to the ship's GPS receiver or other source of positional information，a means must be provided to ensure the continuous supply of the information in the event of a failure to the ship's main or emergency source of power

Key letters or abbreviations may not be used in GMDSS radio logbooks under any circumstance

Urgent communications do not need to be entered in the GMDSS radio log

Both of the above

None of the above

Each compulsory vessel must carry at least two licensed GMDSS Radio Operators at all times while at sea

Each compulsory vessel must carry at least two licensed Radio Operators at all times while at sea and may elect to carry a GMDSS Radio Maintainer as well

Communications involving safety of life at sea do not have to be logged as long as the compulsory vessel was not involved in such communications

While at sea，adjustments to，and the maintaining of，GMDSS equipment may be performed by the GMDSS Radio operator as long as the work is supervised by an onboard licensed GMDSS Radio Maintainer

A fully loaded vessel will be slower to respond to the engines

A fully loaded vessel will maintain her headway further

A light vessel will be more affected by the wind

A light vessel lose more rudder effect in shallow water

Locating signals are transmitted by survival craft VHF transceivers

Locating signals are transmitted by SARTs

Locating signals are intended to facilitate the finding of a distressed vessel or its survivors

Locating signals are not transmitted by autoalarm generators

EPIRB's that transmit on 406 MHz

Survival craft VHF transceivers that provide a beacon on 121.5 MHz

COSPAS-SARSAT EPIRBs

SARTs operating on 9 GHz

Anchoring in the presence of ice is not recommended except in an emergency

Towing a vessel through an ice field is not recommended except in an emergency

The Free and Proceed system of escorting a beset vessel cuts down on the number of freeing operations

When anchoring in ice，it is advisable to increase the scope of the chain over what is normally used for non-icing conditions

A conditional or partial exemption may be granted，in exceptional circumstances，for a single voyage outside the sea area for which the vessel is equipped

Once a compulsory vessel's GMDSS station has been fitted and inspected，the station must be inspected only once every five years

All passenger vessels and all cargo vessels that are 300 Gross Tons or larger must comply

Compulsory vessels must carry at least two licensed GMDSS Radio Operators

When any vessel fails to understand the intentions of an approaching vessel she must sound the danger signal

Only the stand-on vessel can sound the danger signal

Distress signals may be used in place of the danger signal

The danger signal consists of 4 or more short blasts of the whistle

Raising the antenna height increases the radar range

The ability of radar to detect objects is unaffected by weather conditions

Radar bearings are less accurate than radar ranges

Radar should be checked regularly during clear weather to ensure that it is operating properly

A higher interleave depth provides more protection from burst of noise on the HFC network

Higher interleave depth increase downstream latency

Lower interleave depth cause some packet loss on typical HFC networks

A vessel which cannot avoid a close-quarters situation with a vessel forward of her beam shall reduce her speed to bare steerageway

A vessel which hears a fog signal forward of her beam shall stop her engines

A vessel which hears a fog signal forward of the beam shall navigate with caution

If a vessel determines by radar that a close-quarters situation is developing，she shall take avoiding action in ample time

Fresh water may be obtained from fish

Lifeboat covers or canopies should be washed with rain before drinking water is collected

Fresh water may be collected from condensation inside the liferaft

Seawater should never be consumed
