Coastal Navigation Standard
The following is covered
in the Home study Coastal Navigation course.
OBJECTIVES
To be able to demonstrate the
navigational theory required to safely navigate a sailing cruiser in coastal or inland waters. The concepts are
introduced in the Intermediate Cruising and Power Standards. The Navigation Standard is applied practically and
tested in the Advanced Cruising Standard.
PREREQUISITES
None.
This is one of the standards required by Sail Canada as a prerequisite to taking
the Advanced Cruising
Standard. You can attain this
navigation standard by passing the Sail Canada Coastal Navigation Standard Examination.
ASHORE
KNOWLEDGE
You must be able
to:
- Explain the chart symbols and conventions on
Canadian Hydrographic charts, in accordance with the terminology of Chart #1;
- Identify a source of official Canadian
government navigation publications;
- List the publications required for prudent
navigation in the local area, including the following minimum requirements:
a) Large scale charts of the area and Chart #1, Symbols & Abbreviations,
b) Sailing
Directions,
c) Tide and Current
Tables,
d) Collision
Regulations,
e) Local rules and regulations,
f) List of Lights, Buoys, and Fog
Signals,
g) Radio Aids to Marine
Navigation (if using electronic navigation)
h) Transport
Canada Safe Boating Guide;
- List the instruments required for prudent
navigation in the local area, including the following minimum requirements:
a) Steering compass and deviation table,
b) Handbearing compass,
c) Dividers,
d) Protractor, plotter or parallel rule,
e) Watch or clock,
f) Depth sounder or lead line
g) Log/knotmeter,
h) Pencil/eraser/note book;
- Describe the purpose of Notices to
Mariners;
- Use the Tide and Current Tables to
find:
a) Times and heights of tides at reference and secondary ports,
b) Direction and rate of current at reference and secondary
stations;
- Convert courses, headings and bearings
between true, magnetic, and compass;
- Check compass deviation by means of a
transit bearing;
- Plot:
a) dead reckoning position on a chart, using speed, time, and course through
water,
b) The estimated position allowing for the effect of current and
leeway;
- Determine a heading that
counteracts:
a) Known current,
b) Leeway;
- Given the course through water and speed,
and two observed positions, determine the current;
- Determine:
a) Estimated Time of Arrival (ETA),
b) Revised ETA;
- Plot a chart position from terrestrial
objects, using:
a) Two or more bearings on different objects taken at one time
b) A running fix on one or two objects
c) One bearing and a transit/range
d) One distance (i.e. a sounding, or dipping a light) and one
bearing;
- Use correct plotting and labeling procedures
as outlined below;
- Demonstrate knowledge of passage planning
by:
a) Prepare a plan of a coastal passage of at least 20 miles in three stages: i)
Overall plan on a small scale chart, ii) a detailed plan on a large scale chart, iii) and a departure or
arrival plan including tide and current information.
b) Use transits, lead marks, stern marks and clearing bearings in passage
planning;
c) Transfer positions between charts using nearest compass rose and measuring
distances;
d) Demonstrate a working knowledge of the Canadian buoyage and aids to navigation
systems.
Sail Canada Uniform
Navigation Standard Terminology:
- Course: The direction in which a boat is steered or is intended to be steered (direction
through the water).
- Course to
steer: Course to steer to counteract current and
leeway
- Heading
(HDG): The direction in which the boat is pointing in any
instant.
- Course To Make Good
(CTMG): The course for planning purposes that indicates the
intended track from departure to destination.
- Course Made Good
(CMG): The single resultant direction from the point of departure
to the point of arrival at any given time.
- Line of Position
(LOP): A plotted line that the boat is located on at a specific
time, which may be based on a distance off, or the bearing of a charted object of known
location.
- Speed (S): The speed of the boat through the water.
- Speed Made Good
(SMG): The speed of the boat achieved over the CMG
line.
- Set (Set): The direction in which the current is flowing.
- Drift (DFT): The speed (in knots) of the current.
- Total Drift: Distance between the DR position and Fix for the same
time.
- Symbols, Abbreviations &
Labeling:
a) Headings/
directions: always 3 numbers followed by:
T= True (default), M= Magnetic, C= Compass
b) Time: 24 hour clock, ship time used
