Mauritius offers a robust and highly regulated maritime jurisdiction for shipowners, governed primarily by the Merchant Shipping Act 2007 and the Merchant Shipping Regulations 2009. The country provides shipowners and maritime investors with a secure legal framework, operational flexibility and a streamlined administrative process.
In this guide, we cover the eligibility criteria and technical prerequisites for Mauritian flag registration, walk through the step-by-step registration procedure and explain the rules governing bareboat charter arrangements and vessel markings. We also outline how foreign investors can access the Mauritius vessel register through a locally incorporated entity.
- Mauritius permits parallel registration, allowing a vessel owned by a Mauritian entity to be registered in a foreign bareboat charter registry while the local registration is temporarily suspended.
- Ships are generally not accepted for first registration if they are more than 15 years old from the date of initial construction completion, though exemptions may apply.
- Foreign investors can register a vessel in Mauritius by incorporating a Global Business Company (GBC), which may qualify for an effective corporate tax rate of 3% on qualifying shipping activities.
- The registration process follows a structured sequence, starting with proof of ownership and vessel survey, and ending with physical marking and insurance, all under the supervision of the Director of Shipping and the Registrar of Ships.
Why register a vessel under the Mauritian flag?
The Mauritian flag offers a combination of legal protection, financial flexibility and international credibility, making it attractive to both local and foreign shipowners. Its legal framework supports complex ownership structures while maintaining compliance with major international maritime conventions.
A key advantage is the ability to use parallel registration for bareboat chartering. A Mauritian-owned vessel can be registered in a foreign bareboat charter registry. Conversely, a foreign vessel chartered to a Mauritian entity can be registered under the Mauritian flag. During this period, the Mauritian registration is temporarily suspended and most fees are waived, except for crew and radio fees.
The framework also allows shipowners, salvors and charterers to limit their liability for maritime claims, including loss of life, personal injury and property damage arising from the operation of the ship. This protection is particularly relevant for operators managing vessels across multiple jurisdictions.
For lenders and financiers, the register provides strong mortgage protection. Mortgages are ranked by registration order, and a registered mortgage remains enforceable even if the mortgagor becomes bankrupt, ensuring the lender’s priority over other creditors.
Foreign ownership and the representative person requirement
A vessel registered in Mauritius must be owned by a Mauritian citizen, a Mauritian company or a recognised maritime entity. Where majority owners are not Mauritius residents, the vessel can still be registered if a locally resident representative person is appointed.
The representative person may be an individual or a body corporate, including the managing owner of the ship. Their details must be declared to the Registrar at the time of application and recorded in the Register. This appointment must remain in place for as long as the vessel is registered, and any changes to their details must be promptly notified. Once appointed, that representative person is subject to the requirements of the Merchant Shipping Act and is responsible for complying with the Registrar’s instructions on behalf of the ship or its owner.
Eligibility and technical requirements for registering a vessel
Before starting the registration procedure, owners must ensure the vessel meets Mauritius’ technical standards. These include requirements relating to the vessel’s age, classification and compliance with applicable international maritime conventions.
Age and classification of vessels
A vessel is generally not accepted for first registration if it is more than 15 years old from the date of initial construction completion. The Registrar may grant exceptions in specific cases. Ships of 500 gross tons and above must also maintain classification with a recognised classification society, such as Lloyd’s Register or Bureau Veritas.
International convention compliance
The vessel must comply with the major international conventions to which Mauritius is a party. These include the International Convention for the Safety of Life at Sea (SOLAS) 1974, the International Convention for the Prevention of Pollution from Ships (MARPOL) and the International Load Lines Convention. Valid compliance certificates must be provided as part of the registration process.
What is the procedure for vessel registration in Mauritius?
Registration of a vessel under the Mauritius flag follows a structured procedure managed by the Director of Shipping and the Registrar of Ships. In summary, the process involves application and proof of title, survey and tonnage measurement, carving and marking of the vessel, proof of insurance and final registration with issuance of the certificate. These steps are explained in detail below.
Step 1: Application and proof of title
The applicant submits the prescribed application form together with the evidence of ownership. For a new vessel, this is a builder’s certificate; for an existing vessel, a bill of sale or equivalent document is required. A declaration of ownership must also be provided, confirming shareholding and eligibility to own a Mauritius-registered ship.
Step 2: Survey and tonnage measurement
Prior to registration, the vessel must be surveyed to determine its tonnage in accordance with applicable regulations. If a foreign-flagged ship is transferring to the Mauritius register and already holds a valid International Tonnage Certificate, the Director of Shipping may accept the existing measurement without a re-survey.
Step 3: Carving and marking
Once the application is approved, the Registrar issues a carving and marking note. The vessel must then be permanently marked as follows:
- The approved name on both bows and the name with the port of registration (Port Louis) on the stern
- The official number and net tonnage cut into the vessel’s main structure
- A scale of metres indicating the vessel’s draught markings on the stem and stern
- For vessels subject to the International Ship and Port Facility Security (ISPS) Code, the unique identification number marked on the exterior hull and an internal bulkhead
These markings must be verified by an inspector before registration can proceed.
Step 4: Proof of insurance
At the time of first registration, the owner must provide evidence of third-party liability insurance, covering crew liabilities, cargo damage and wreck removal.
Step 5: Final registration and certificate issuance
Once all requirements are satisfied, including markings, ownership documentation and compliance certificates, the vessel is entered into the Register, and a Certificate of Registration is issued.
Requirements for vessel marking in Mauritius
Requirements for vessel marking under the Merchant Shipping Act vary depending on the type and size of the vessel. Owners must ensure all markings are permanent, clearly visible and compliant with the prescribed standards.
Marking requirements for general vessels and pleasure yachts
Marking requirements differ for general vessels and pleasure yachts, particularly in terms of placement and lettering size. The main requirements are set out below.
| Requirement | General vessels | Pleasure yachts (under 24m) |
|---|---|---|
| Location of markings | Name on both bows; name together with the Port Louis on stern (or stern only with approval from Director of Shipping) | Name and Port Louis on a permanent, visible part of the stern |
| Letter size | Minimum 10 cm in height with proportionate width | Minimum 5 cm high |
| Visibility | Must be clearly visible and in contrasting colour | Must be clearly visible |
| Format | Name in Roman letters; numerals in Roman or Arabic | Same standard applies |
| Alternative methods | Not typically applicable | Engraved plates, carved wooden blocks or glass-reinforced plastic letters fixed with epoxy (where standard marking is not feasible) |
Rules on vessel name changes and bareboat registration
A vessel’s name cannot be changed without written permission from the Registrar of Ships. Once approved, the new name must be updated on the vessel and reflected in both the Register and the Certificate of Registration. If a Mauritius-registered vessel is temporarily registered in a foreign bareboat charter registry, the Port Louis must be removed from the stern for the duration of that registration.
Registration requirements for vessels under bareboat charter
Mauritius provides a dedicated framework for vessels operating under bareboat charters. A Mauritius company chartering a foreign vessel may register it under the Mauritian flag by submitting a copy of the charter agreement, a statement of the charter terms and the primary registry certificate. Typically, the charter must be for a minimum period of two years, although the Director of Shipping may approve shorter durations where justified.
During the charter registration period, the vessel is issued a certificate of bareboat charter registry and flies the Mauritian flag. Fee exemptions available under parallel registration apply, except for ongoing crew and radio fees.
How to register a vessel through a locally incorporated entity in Mauritius
Mauritius offers a clear pathway for foreign investors to access its vessel register through a locally incorporated entity. A common approach is to establish a Mauritius Global Business Company (GBC), which can be 100% foreign-owned. Once incorporated and duly licensed, the GBC can own and register a vessel under the Mauritian flag. For a broader overview of the corporate structures available in Mauritius, refer to our guide on offshore and onshore business structures.
Tax treatment of GBCs in shipping
Where a GBC is engaged in qualifying shipping or vessel-related activities, it may benefit from an effective corporate tax rate of 3%, compared to the standard 15% rate. This is subject to compliance with the substance, licensing and regulatory requirements applicable to GBCs. Further insights into the tax treatment of GBCs are available in our detailed taxation guide.
Uses of GBC structures for vessel ownership
GBC structures are widely used for yacht ownership, commercial shipping operations, chartering arrangements and maritime asset holding. Company directors should also be aware of their ongoing legal and compliance obligations.
Conclusion
Mauritius offers a well-regulated, flexible and internationally recognised framework for vessel registration. Its ability to accommodate foreign ownership, provide strong mortgage protection and allow parallel registration makes it suitable for a wide range of maritime operators. The registration process is clear and structured, with defined requirements covering documentation, marking, insurance and convention compliance.
For foreign investors, the availability of GBC structures and a competitive tax regime can further enhance its appeal. Consulting with an expert in Mauritian maritime and corporate law before starting the process helps ensure that all legal, structural and procedural requirements are properly addressed.
