Abstract : This paper examines the regulatory gap concerning redundant navigation equipment on modern commercial vessels, specifically analyzing the functional overlap between traditional course recorders, echo sounders, and Voyage Data Recorders (VDRs). Through a systematic review of International Maritime Organization (IMO) regulations, classification society guidance, flag state interpretations, and industry association publications, this research reveals a comprehensive absence of official guidance harmonizing SOLAS Chapter V Regulations 19 and 20. The findings demonstrate that VDRs record all parameters captured by standalone course recorders and echo sounders, yet shipowners continue to bear the operational costs of maintaining redundant equipment due to regulatory ambiguity. This paper argues that the regulatory framework has not adapted to technological advancement, creating unnecessary economic burden on the maritime industry while maintaining the appearance of compliance with outdated operational assumptions. The analysis concludes with recommendations for regulatory modernization and calls for IMO action to address this systematic inefficiency.
