What is the minimum diameter allowed for bilge piping on small passenger vessels which are more than 65 feet in length?
AI Explanation
The correct answer is B) 1-1/2".
According to the US Coast Guard regulations for small passenger vessels greater than 65 feet in length, the minimum diameter allowed for bilge piping is 1-1/2 inches. This requirement is specified in 46 CFR 182.500, which outlines the standards for bilge and ballast systems on these types of vessels.
The other options are incorrect because 1 inch (A) would be too small, while 2 inches (C) and 2-1/2 inches (D) would be larger than the minimum requirement.
