General Ship Knowledge 1 — Questions and Answers
Question 1: Why are children under the age of 12 not advised to wear inflatable life jackets?
- Children's favorite colors are not available for inflatable life jackets.
- The cost of inflatable life jackets is high.
- While playing near the water, kids may mistakenly trigger an auto-inflating life jacket or forget how to use a manual inflated life jacket in an emergency. (Correct answer)
Correct answer: While playing near the water, kids may mistakenly trigger an auto-inflating life jacket or forget how to use a manual inflated life jacket in an emergency.
Inflatable life jackets are generally not recommended for children under 12 due to safety concerns. Young children might accidentally activate an auto-inflating jacket while playing, or they may lack the presence of mind or strength to manually inflate it during a real emergency. Traditional foam life jackets offer constant buoyancy without requiring user action.
Question 2: How should life jackets be maintained?
- Clean off any salt, inspect for damage, and then store them in a dry, shaded area. (Correct answer)
- In between uses, place them in a pail of ice-cold, clean water.
- Frequently expose them to sunshine.
Correct answer: Clean off any salt, inspect for damage, and then store them in a dry, shaded area.
Proper maintenance of life jackets is crucial for their effectiveness and longevity. Cleaning off salt prevents corrosion and material degradation, while inspecting for damage ensures they remain in good working condition. Storing them in a dry, shaded area protects them from UV damage and mildew, preserving their structural integrity.
Question 3: Why do inflatable life jackets require routine maintenance?
- If you don't get them serviced, they are tough to store. (Correct answer)
- They might not inflate you when you need them if they are not in working order.
- If you don't service them, the plastic wrapping will start to deteriorate.
Correct answer: If you don't get them serviced, they are tough to store.
Routine maintenance for inflatable life jackets often involves ensuring they are properly deflated and repacked after use or accidental inflation. If these steps are not followed as part of their servicing, the inflated or improperly folded jacket becomes bulky and cumbersome, making it difficult to store efficiently on board a vessel. This highlights the importance of proper handling and servicing for practical storage.
Question 4: When is a waterproof torch required to be carried on board a motorised vessel (other than a personal watercraft)?
- All the time. (Correct answer)
- Only when traveling on open waters greater than 2 nautical miles from the coast.
- Just from dusk until dawn.
Correct answer: All the time.
A waterproof torch (flashlight) is a crucial safety item required on board motorized vessels at all times, not just at night or in specific conditions. It serves as an essential signaling device in emergencies, helps with navigation in low light, and can be used for inspecting equipment or finding items in the dark, regardless of the time of day or distance from shore.
Question 5: What is the bare minimum of distress flares that a ship operating in open waters must carry?
- 3 red hand flares and 3 orange smoke flares.
- None.
- 2 red hand flares and 2 orange smoke flares. (Correct answer)
Correct answer: 2 red hand flares and 2 orange smoke flares.
For vessels operating in open waters, specific safety regulations often mandate carrying a minimum number and type of distress flares. Two red hand flares are used for signaling distress at night or in low visibility, while two orange smoke flares are effective for daytime signaling, making the vessel visible to rescuers. This combination ensures visibility in various conditions.
Question 6: When is it necessary to have a fire extinguisher on board your boat?
- Only if the vessel is a commercial one.
- Only when a battery, fuel stove, gas system, or engine is present on the vessel. (Correct answer)
- Only if you're entering open water.
Correct answer: Only when a battery, fuel stove, gas system, or engine is present on the vessel.
Fire extinguishers are required on boats primarily when there are potential sources of ignition and flammable materials. The presence of a battery (which can short circuit), a fuel stove, a gas system, or an engine (with fuel and electrical components) significantly increases the risk of fire, necessitating an onboard extinguisher for safety.
Question 7: When is a General Boat Driver's License required?
- Only when operating a business ship.
- Only when traveling over 20 mph in NSW waters when operating a motorized vessel.
- Only when traveling over 10 knots in NSW waters when operating a motorized vessel. (Correct answer)
Correct answer: Only when traveling over 10 knots in NSW waters when operating a motorized vessel.
In New South Wales (NSW), Australia, a General Boat Driver's License is specifically required when operating a motorized vessel at a speed of 10 knots or more. This regulation ensures that operators of faster vessels have demonstrated the necessary knowledge and skills to safely navigate and control their boat, promoting safety on the waterways.
