A self-propelled vessel of 12,000 gross tons, not a tank vessel and not carrying hazardous materials, was constructed in 1990 and operates on the navigable waters of the United States. Under 33 CFR §164.38, is this vessel required to carry an ARPA?
- A. No, because it is not a tank vessel and does not carry hazardous materials
- B. No, because the 15,000 GT threshold applies to all non-tank vessels regardless of construction date
- ✓ Yes, because it is 10,000 GT or more and was constructed on or after September 1, 1984Correct
- D. Yes, but only when transiting waters west of the Mississippi River
Why C is correct
33 CFR §164.38(b)(4) requires each vessel of 10,000 gross tons or more constructed on or after September 1, 1984 to be equipped with an ARPA, with the exception of vessels operating on the Great Lakes and their connecting and tributary waters. The 15,000 GT threshold in §164.38(b)(3) applies only to vessels constructed before September 1, 1984.
