International Registries, Inc. providing support to the Marshall Islands Maritime & Corporate Administrators


This section provides vessel owners, operators, charterers, lending institutions and their representatives with information needed to register vessels in the Republic of the Marshall Islands (RMI) and related instruments under MI-300.

International Registries, Inc. (IRI) has staff available to consult with you to ensure that your documents qualify under RMI Law, and to assist you with other features and requirements of the RMI Maritime Act (the Act) 1990, as amended. There is no charge for this service. Guidance on the content and interpretation of applicable international conventions, rules and regulations may also be obtained in consultation with our technical staff.

In addition, you may consult the RMI publication MI-100, Vessel Registration and Mortgage Recording Procedures for more detailed information. Although the MI-100 has application forms attached, they are not set up to be used electronically. You may print out what you need and fill it in manually. If you want to be able to fill out the forms electronically, you will need to go to the Vessel Registration section in Forms and Publications.

  • Types of vessels that may be registered under the RMI flag include: tankers, cargo ships, containerships, passenger vessels, MODUs, tugs, yachts, fishing vessels and other ocean-going vessels
  • Vessels should be under 20 years of age at time of registration. A waiver of the age requirement may be granted depending upon a satisfactory evaluation of the condition, seaworthiness and usage of the vessel
  • Ownership must be in the name of a RMI National, Corporation, General Partnership, Limited Partnership (LP), Limited Liability Company (LLC) or Foreign Maritime Entity (FME) qualified in the RMI

All commercial vessels are required to be classed by a Classification Society that is recognized by the Maritime Administrator (some exceptions may be made for yachts and fishing vessels; contact IRI for specifics). The following are currently recognized:
