Q

What is “display base” in relation to eNav systems?

A

The chart content that cannot be removed from the display. This represents the minimum set of information and is not intended to be sufficient for navigation. Shallow water, safety contour, and isolated hazards to navigation are included in the display base based on cutter or boat depth information entered into the eNav system.

31
Q

What signifies a warning alarm on an eNav system?

A

The system produces a brief audible alarm and flashes yellow. Warning alarms alert the user to issues that, if left uncorrected, could compromise safety of navigation.

Q

How long are electronic charts good for on small boats?

A

A chart is currently corrected if it has been corrected within the last 6 months.

39
Q

What must be done if a small boat’s chart has a NTM/ LNM issues during it’s six month issuance?

A

If NTMs/LNMs have been issued past the manufacturer’s electronic chart base date, then CO/OICs can authorize use of SINS as a primary means of navigation if a currently corrected and prepared paper chart is immediately available.

40
Q

If your fix interval is three minutes or greater, how often do you have to determine set and drift?

A

If fix interval is three minutes or greater, determine set and drift with every fix.

Q

If your fix interval is less than three minutes, how often do you have to determine set and drift?

A

If the fix interval is less than three minutes, determine set and drift with every second fix.

42
Q

What are the rules of dead reckoning?

A

1) Plot a DR position at least every hour on the hour
2) Plot a DR position at every course change
3) Plot a DR position at every speed change
4) Regenerate DR plot after each fix or running fix
5) Plot a DR position when obtaining a single line of position

43
Q

What must be documented when a ship anchors?

A

The Ship’s Log must include time of anchorage, depth of water, which anchor used, scope of chain, type of bottom, ship’s head, and bearings to objects designated by the Navigator.

Q

What is a swing circle?

A

The Swing Circle, centered on the anchoring location, has a radius equal to length of the vessel added to the length of anchor chain released.

45
Q

What is a drag circle?

A

The Drag Circle, centered on the anchoring location, has a radius equal to the distance from the hawsepipe to pelorus, radar antenna, or GPS antenna, added to the length of the anchor chain released.
