Fixed ballast, if used, may be __________. (small passenger vessel regulations)

Correct Answer: Option C — moved temporarily for examination or repair of the vessel, when done under the supervision of an inspector

46 CFR 178.230 dictates that fixed ballast is essential for vessel stability and must not be altered. It may only be moved temporarily for necessary vessel repairs or inspections, and this must be performed under the direct supervision of a USCG Marine Inspector to ensure stability remains compliant.
