Question 1856 Deck General

The correct answer is B) The removal of a watertight bulkhead. The removal of a watertight bulkhead on an inspected passenger vessel would require the knowledge and approval of the Officer in Charge, Marine Inspection (OCMI). Watertight bulkheads are critical safety features that help maintain the vessel's structural integrity and compartmentalization in the event of flooding. Any modifications to these features must be reviewed and approved by the OCMI to ensure the vessel's continued seaworthiness and compliance with small passenger vessel regulations. The other options are incorrect because a minor overhaul of the propulsion machinery (A) and the renewal of an FCC certificate for a radiotelephone (C) do not typically require OCMI approval, as they are more routine maintenance or administrative tasks.
