Vessels constructed after what date must be equipped with an ARPA?

Explanation:
ARPA requirements in maritime regulation: vessels built after a certain date must have Automatic Radar Plotting Aids. ARPA enhances radar by automatically tracking multiple targets, computing closest point of approach and time to CPA, and assisting with collision avoidance. Regulations from SOLAS set this rule for new ships; the threshold date is September 1, 1984. That means any vessel constructed after that date must be equipped with ARPA. The other dates don’t reflect when the requirement took effect, so they don’t match the regulatory threshold.
