🔍 Key Concepts

• 33 CFR 155.450 – Placard requirements for discharge of oil • Difference between inspected commercial vessels and uninspected recreational vessels • Minimum length in feet and type of operation that trigger placard requirements

💭 Think About

• Look at which choices are commercial versus purely recreational and how that affects pollution placard rules • Ask yourself: what is the minimum vessel length that requires an oil discharge placard under 33 CFR? • Consider whether manned vs unmanned or naval vs civilian status changes the requirement

✅ Before You Answer

• Verify which vessel types in 33 CFR 155.450 are explicitly required to display an oil discharge placard • Check the length threshold in feet at which the regulation starts to apply • Confirm whether recreational vessels of that size and use are treated differently from commercial vessels for this specific placard requirement
