Which condition must be met during a...

🔍 Key Concepts

• Stability test purpose – what naval architects are trying to learn from an inclining experiment or stability test • Environmental and mooring conditions – how outside forces (lines, bottom, current) can affect test accuracy • Difference between securing loose gear vs. allowing the vessel to move freely in response to test weights

💭 Think About

• Ask yourself: during a formal stability (inclining) test, do we want the vessel’s movement to be restricted or completely free to respond to the shifting test weights? • Which choice, if not satisfied, would most seriously distort the test results about the vessel’s true stability characteristics? • Think about whether tanks should be full, empty, or partially full during an inclining experiment and why free-surface effects matter.

✅ Before You Answer

• Verify which option deals directly with freedom of heel and trim during the test, without outside restraint • Check which condition is specifically required in stability test procedures in 46 CFR (inclining experiments) rather than just being general good seamanship • Make sure the condition you pick is something that, if not met, would invalidate the test data, not just make the deck safer or neater

Which condition must be met during a stability test on an inspected vessel?

All dunnage, tools, and extraneous items are secured

Water under vessel must be deep enough to prevent grounding

The vessel must be moored snugly

Each tank must be partially full to show it does not leak
