Understanding CATZOC System

What is the main purpose of the CATZOC system on ENCs?

• Enhance vessel speed

• Classify bathymetric data quality

• Reduce fuel consumption

• Measure atmospheric conditions

Which parameter is NOT a part of CATZOC classification?

• Depth Accuracy

• Position Accuracy

• Seafloor Coverage

• Fuel Consumption

What does CATZOC provide to mariners during voyage planning?

• Information on chart reliability

• Historical weather data

• Crew performance metrics

• Vessel maintenance schedules

What is the significance of ZOC A1?

• It is the highest quality level in CATZOC

• It is unassessed and undefined

• It has the lowest position accuracy

• It is meant for environmental zones only

Why are safety margins important in CATZOC?

• To facilitate port entry

• To ensure adequate clearance and reduce navigational risks

• To improve vessel fuel efficiency

• To determine engine power output

What does CATZOC stand for?

Which CATZOC category indicates unassessed data?

• ZOC A1

• ZOC D

• ZOC C

• ZOC U

What does 'ZOC A2' imply in CATZOC levels?

• Highest quality with accurate depths

• High quality but slightly less than A1

• Low quality with no accuracy standards

• Unassessed level with no confidence

What parameter does CATZOC NOT consider?

• Seafloor Coverage

• Position Accuracy

• Depth Accuracy

• Engine Power

Which formula uses CATZOC to calculate navigational safety?

• Maneuvering Margin Calculation

• Fuel Consumption Formula

• Safety Contour Formula

• Navigation Clearance Ratio
