🔍 Key Concepts

• Methods to increase a vessels visibility to persons in liferafts • Differences between visual detection at night vs. day • Safety and pollution concerns with dumping debris overboard

💭 Think About

• If you were in a low liferaft on the water at night, what features of a ship would be most noticeable to you from a distance? • Which options could actually make it harder to track the ships movement or confuse survivors about your exact position? • Which option might violate pollution or safety rules rather than help with search and rescue?

✅ Before You Answer

• Identify which choice directly increases light and contrast that survivors can see from a low angle near the waterline. • Eliminate any options that involve unnecessary course changes that do not improve visibility. • Eliminate any option that clearly conflicts with pollution prevention or good seamanship.
