Question 2670 Deck General

The correct answer is D) under no circumstances. According to U.S. Coast Guard regulations, U.S. Coast Guard approved work vests cannot be substituted for life jackets on uninspected vessels. Life jackets are the required lifesaving equipment, and work vests do not provide the same level of protection or buoyancy as a proper life jacket. The regulations are clear that life jackets must be used, and work vests are not an acceptable alternative under any circumstances on uninspected vessels. The other options (A, B, and C) are incorrect because the regulations do not allow for the substitution of work vests for life jackets, regardless of the type of uninspected vessel.
