Ships Routeing System Quiz

Routeing Charts

• Provide information on wind force and direction at various points on the chart.
• Show sea currents at various points on the chart.
• Indicate areas of low visibility.
• Display mean dew point temperature and mean atmospheric pressure at sea level.
• Available for each month throughout the year, with 12 charts for each area.

Areas Covered

• North Atlantic Ocean: 12 charts (1 for each month)
• South Atlantic Ocean: 12 charts (1 for each month)
• Indian Ocean: 12 charts (1 for each month)
• North Pacific Ocean: 12 charts (1 for each month)

Purpose of Routeing Charts

• Assist navigators in planning an ocean passage for any time of year.
• Provide essential information for safe and efficient navigation.

Information Provided

• Outline of surrounding land areas and major ports.
• Recognized shipping routes between major ports, with distances.
• Data on wind speed, direction, and force.
• Data on ocean currents.
• Limits of loadline zones and locations of ocean weather.
• Incidence of low visibility and frequency of storms.
• Data on sea and air temperature, air pressure, and ice limit.

Updating Routeing Charts

• Generally updated via a new version of the chart every few years by the Admiralty chart services.
• Rarely, a small update comes with the Admiralty Notice to Mariners and has to be done manually.

Information from Routeing Charts

• Essential for passage planning for ocean voyages.
• Include routes and distances between major ports, ocean currents, ice limits, load lines, and wind roses.
• Contain expected meteorological and oceanographic conditions for each month of the year.
• Provide information on:
  • Ice limits and icebergs in relevant areas.
  • Load line zones for various oceans along with applicable dates, if any.
  • Shipping routes between major ports, along with distances written on the routes.
