USCG Exam Practice · Radar fundamentals and ARPA basics
A vessel of 10,000 gross tons was constructed on September 15, 1984, and operates exclusively on the Great Lakes and their connecting and tributary waters. Under 33 CFR §164.38, is this vessel required to be equipped with an ARPA?
- AYes, because the vessel is 10,000 gross tons or more regardless of operating area
- BYes, because the vessel was constructed after September 1, 1984
- CNo, because vessels operating on the Great Lakes and their connecting and tributary waters are specifically exempted from the ARPA requirement under §164.38(b)(4)✓ correct
- DNo, because the ARPA requirement only applies to tank vessels on the Great Lakes
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, but explicitly excepts vessels when operating on the Great Lakes and their connecting and tributary waters. The exemption applies to the operating area, not vessel type.
