🔍 Key Concepts

• 46 CFR Subchapter S – Subdivision and Stability • Meaning of sister vessel and use of existing stability data • When the Coast Guard may accept existing test results instead of requiring a new test

💭 Think About

• Which option describes a situation where the vessel’s stability is already well-documented for a nearly identical vessel? • Do administrative or cost issues by themselves allow you to skip a required safety test under Coast Guard regulations? • Among the choices, which one gives the Coast Guard a solid, technical basis to judge stability without repeating the test?

✅ Before You Answer

• Verify which choice involves an objective technical basis for stability, not convenience or cost • Ask whether the vessel’s design and loading characteristics are already proven by data on an almost identical vessel • Eliminate any option that relies only on practical difficulties (money, staffing, schedule) rather than safety and prior test results
