Dead Reckoning

Back 1

The process of determining one’s
present position by projecting course(s) and speed(s) from
a known past position, and predicting a future position by
projecting course(s) and speed(s) from a known present
position.

Front 2

Uses For Dead Reckoning

Back 2

predicting arrival times, evaluating the accuracy
of electronic positioning information, evaluate external forces
acting on his ship, and to avoid potential
navigation hazards.

When to Plot DRs

Back 10

1 A DR position will be plotted every hour on the hour.
2 A DR position will be plotted at the time of every course
change.
3 A DR position will be plotted at the time of every speed
change.
4 A DR position will be plotted for the time at which a fix or
running fix is obtained.
5 A DR position will be plotted for the time at which a single line
of position is obtained.
6 A new course line will be plotted from each fix or running fix as
soon as it is plotted on the chart.

Does a DR take in account Set and drift?

Back 11

No, thats an EP

Front 12

Fix Expansion

Back 12

takes into account possible errors in the
DR calculation caused by factors which tend to affect the
vessel’s actual course and speed over the ground. The
navigator considers all such factors and develops an
expanding “error circle” around the DR plot. This accounts for effects of current, leeway, and steering error.

Course

Back 24

the horizontal
direction in which a vessel is intended to be steered,
expressed as angular distance from north clockwise through
360°. Strictly used, the term applies to direction through the
water, not the direction intended to be made good over the
ground.The course is often designated as true, magnetic,
compass, or grid according to the reference direction.

Wind Motherboard Steps:

Back 34

Draw ships heading (ER)
Arc ships speed
At ships speed, draw out apparent wind along from speed arc
-so if 30 deg of a 90 deg head, draw a line going 30 degrees from ships bow, not absoulute. Draw a line in direction of wind (RW)
Go to center, EW heading is how line traveled back to the ship, not towards outer (oppisite)

Front 35

Front 38

What if you 7 knots in 7 minutes, how far did you travel

Back 38

1 kts/min x 3min = 3kts/3min

Back 58

A line of bearing to a known object, which a vessel is presumed to be located
on at some point.

Front 59

Fix

Back 59

A fix is a position determined from terrestrial, electronic or celestial data at a
given time with a high degree of accuracy

Front 60

Estimated position

Back 60

A DR position modified by additional information, which in itself is
insufficient to establish a fix.

Front 61

Position

Back 61

Position refers to the actual geographic location of a boat. It may be
expressed as coordinates of latitude and longitude or as the bearing and
distance from an object whose position is known.

Front 62

Heading

Back 62

The actual direction the boat’s bow is pointing at any given time.

Front 63

Course C

Back 63

Course C The intended horizontal direction of travel (the direction intended to go),
expressed as angular distance from a reference direction clockwise from 000°
through 360°. For marine navigation, the term applies to the direction to be
steered. The heading of 360° is always referred to or spoken as 000°.

Front 64

Range

Back 64

There are two types of ranges used in piloting:
• Two or more fixed objects in line. Such objects are said to be in range.
• Distance in a single direction or along a great circle. Distance ranges are
measured by means of radar or visually with a sextant.

Front 65

Running fix

Back 65

A running fix is a position determined by crossing LOPs obtained at different
times.

Front 66

Track

Back 66

A track is the course followed or intended to be followed by a boat. The
direction may be designated in degrees true or magnetic.

Front 67

Drift

Back 67

The speed of the current usually stated in knots.

Front 68

DR Fixes and water

Back 68

In confined waters the navigator will normally take a fix
every three minutes, while in less restricted waters, a fix
may be plotted once every 15 minutes. The DR is laid
out for whatever interval the fixes are being taken.

about which the ship seems to pivot (called the pivot
point) as it executes a 360 degree turn.

Front 75

Advance

Back 75

is the distance gained in the direction of the
original course until the ship steadies on its final
course.

Front 76

Transfer

Back 76

is the distance gained at right angles to the

on its final course.
