The Marshall Islands Official Logbook is a statutory record book designed for vessels registered under the Republic of the Marshall Islands flag administration. This logbook serves as an official onboard document used to record mandatory entries required by maritime regulations, flag state requirements, and vessel operational procedures. It provides a structured format for documenting significant shipboard events, crew-related matters, disciplinary actions, inspections, drills, accidents, incidents, safety activities, and other entries required by applicable regulations.

Maintained under the authority of the Master, the Official Logbook supports regulatory compliance and provides a permanent record of important operational and administrative activities throughout the vessel’s service. Proper completion and maintenance of the logbook assists in demonstrating compliance during flag state inspections, port state control examinations, audits, and company reviews.

The Marshall Islands Official Logbook is intended for use onboard commercial vessels and should be completed accurately and consistently in accordance with company procedures and applicable maritime requirements. As an official ship record, entries should be made promptly and retained as part of the vessel’s documented history and compliance records throughout its operational lifecycle.
