Navigation Part 2
To
further
your
knowledge
and
understanding
of
safely
navigating
a
vessel
from
port
to
port
the
following
skills
are
amongst
some
of
those
that
will
help
you
achieve
this.
The
International
Maritime
Organization
(IMO)
Resolution
A.893(21)
emphasizes
the
importance
of
meticulous
voyage
planning
for
ensuring
safety
at
sea.
It
outlines
a
structured
approach
to
creating
a
comprehensive
voyage
plan
that
covers
all
aspects
of
a vessel's passage, from departure to arrival.
Principles of Voyage planning
Recommended
by
SOLAS
the
four
stages
of
planning
are
Appraisal,
Planning,
Execution
and
Monitoring
logically follow each other.
An
appraisal
of
all
information
available
must
be
made
before
detailed
plans
can
be
drawn
up
and
a
plan
must
be
in
existence
before
tactics
for
its
execution can be decided upon.
Once
the
plan
and
the
manner
in
which
it
is
to
be
executed
have
been
decided,
monitoring
must
be
carried out to ensure that the plan is followed

The
International
Maritime
Organisation
-
Regulation
28
regarding
Records
of
navigational
activities
and
daily
reporting
advises
that
all
ships
engaged
on
international
voyages
shall
keep
on
board
a
record
of
navigational
activities
and
incidents
which
are
of
importance to safety of navigation.
The
records
must
contain
sufficient
detail
to
restore
a
complete
record
of
the
voyage,
taking
into
account
the recommendations adopted by the Organization.
When
such
information
is
not
maintained
in
the
ship's
log-book,
it
shall
be
maintained
in
another
form
approved by the Administration.

Notices
to
Mariners
are
issued
by
several
organisations,
including
the
UK
Hydrographic
Office
(UKHO), Trinity House and local harbour authorities.

A
tidal
curve
is
a
graphical
representation
of
the
predicted
tidal
heights
and
times
for
a
specific
location.
Tidal
curves
use
the
same
tidal
data
that
is
found
in
tide
tables,
usually
presented
as
a
graph
with
time
on
the
horizontal
axis
and
tidal
height
on
the
vertical axis.
The
curve
is
in
two
parts,
the
straight
linear
graph
on the left and the curved part on the right.

Secondary
Port
information
is
provided
in
Nautical
Almanacs
such
as
Reeds’
and
also
in
the
Admiralty
Tide Tables.
These
publications
can’t
possibly
give
complete
Tide
Tables
for
all
of
the
hundreds
of
small
‘Secondary
Ports’
around
the
coast.
Instead
they
give
complete
Tide
Tables
for
all
of
the
larger
‘Standard
Ports’
like
Dover and Devonport (Plymouth).
They
then
also
provide
‘Secondary
Port
Differences’
so
that
times
and
heights
for
any
Secondary
Port
can
be easily worked out.
