DAY24 Q1 OF 5

What is the default safety contour if not specified by the mariner?

• 10m

• 20m

• 30m

• 40m

True or False: The safety contour is an outline which marks the division between safe and unsafe waters.

• True

• False

If a ship's draft is 10m and the UKC requirement is 10%, how would you calculate the safety contour?

• SAFETY CONTOUR = SHIP'S DRAFT + SQUAT + UKC - HEIGHT OF TIDE

• SAFETY CONTOUR = SHIP'S DRAFT + SQUAT + UKC + HEIGHT OF TIDE

• SAFETY CONTOUR = SHIP'S DRAFT - SQUAT + UKC - HEIGHT OF TIDE

• SAFETY CONTOUR = SHIP'S DRAFT + SQUAT - UKC - HEIGHT OF TIDE

What are the potential risks of inappropriate ECDIS safety settings?

• Increased risk of grounding in shallow waters

• Causing unwanted situations

• Render the safety contour alarms meaningless

• All of the above

Why is it important for the Masters, navigating officers, and ship-owners to be aware of the benefits of managing the chart display, safety settings, and alarm system of ECDIS?

• To avoid groundings

• To ensure safe navigation

• To effectively use the ECDIS tool

• All of the above

What color is used to indicate unsafe areas in ECDIS?

• Red

• Blue

• Green

• Yellow

True or False: ECDIS allows the officer to set safety parameters according to the ship's static or dynamic particulars.

• True

• False

If a ship's draft is 12m, the squat is 2m, the UKC is 15%, and the height of tide is 1m, what would be the safety contour?

• 14m

• 15m

• 16m

• 17m

What could be the consequences of navigating officers overlooking the use of ECDIS safety settings due to ignorance or insufficient knowledge?

• Increased risk of accidents

• Inefficient navigation

• Misuse of ECDIS tool

• All of the above
