What is a Seaman’s Book and How Do You Get One?

If you're aiming for a career on a cruise ship or any other vessel, one of the most essential documents you'll need is a Seaman’s Book, also known as a Seaman’s Identification Record Book (SIRB). This article will explain what a Seaman’s Book is, why it’s important for your cruise ship career, and how you can get one to land your dream onboard job.

What is a Seaman’s Book?

A Seaman’s Book is an official document that records a seafarer's career history, qualifications, and sea service. It acts as a logbook of your work experience at sea and certifies your employment on a ship. Whether you're applying for a job on a cargo vessel, cruise ship, or any other type of sea-going vessel, a Seaman’s Book is one of the key documents you will need.

The Seaman’s Book is recognized globally under the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW), which ensures that seafarers meet the required safety and competency standards. It is required for almost any type of seafaring employment and is especially crucial for obtaining a crew visa, entering foreign ports, and working on international vessels.

Why is a Seaman’s Book Important for Cruise Ship Jobs?

If you're pursuing a job aboard a cruise ship, you’ll almost certainly be required to have a Seaman’s Book. Cruise lines typically demand this document as part of the application process, especially for positions that involve working on deck or in other technical roles. It provides an official record of your sea experience and can also act as a travel document in certain countries.

A Seaman’s Book can even waive visa requirements in some instances. For example, if you need to enter a country to board or disembark a vessel, a Seaman’s Book can sometimes be used instead of a visa, depending on the agreements between countries that are signatories to conventions such as the International Labour Organization (ILO) Convention No. 108 and No. 185. This can simplify the often complex process of working internationally as a cruise ship employee.

Who Can Apply for a Seaman’s Book?

Anyone who is currently working or looking to work in the maritime industry, including on cruise ships, can apply for a Seaman’s Book. This applies to a wide range of roles, including deck officers, engineers, hospitality staff, and more.

Most flag states—the countries under which ships are registered—have their own requirements for issuing a Seaman’s Book. Generally, applicants must meet certain age requirements (usually 18 or older), hold a valid passport, and pass a medical exam, among other qualifications. It’s also important to note that the Seaman’s Book is typically valid for five years, after which it will need to be renewed.

How to Get a Seaman’s Book

Now that you know what a Seaman’s Book is and why it’s essential, let’s look at how you can apply for one. Here are the typical steps you'll need to follow:

1. Choose the Flag State

The first step is to identify the flag state under which you’ll be working. A flag state is the country where your cruise ship is registered. Common flag states include Panama, Liberia, Marshall Islands, and Vanuatu. Each of these countries has slightly different requirements for issuing a Seaman’s Book, so it’s important to apply to the appropriate one based on the ship you’ll be working on.

2. Complete the Application Form

Once you’ve identified the appropriate flag state, you’ll need to fill out an application for their Seaman’s Book. The form typically asks for personal information such as your name, address, passport details, and work history. Make sure to double-check the requirements for the specific flag state to ensure you're providing the correct information.

3. Provide Supporting Documents

You will need to submit several documents along with your application. These usually include:

  • A copy of your valid passport: This must be signed and include the identification page.
  • Passport-sized photos: These should meet the specific requirements of the flag state.
  • Medical certificate: Most flag states require proof that you are medically fit for sea service. You’ll likely need a medical certificate such as the Oil & Gas UK (OGUK) or a similar certificate recognized by the flag state.
  • Proof of seafaring qualifications or training: If applicable, submit documentation of any maritime training or certifications you’ve completed.

4. Submit the Application

After gathering all the necessary documents, submit your completed application to the appropriate maritime authority of the flag state. This can often be done online, although some countries may require you to submit physical documents through the mail or in person at a consulate or maritime authority office.

5. Pay the Application Fee

There is usually an application fee for processing the Seaman’s Book. The cost can vary depending on the flag state, so be sure to check the exact amount before submitting your application.

6. Wait for Processing

Once your application has been submitted, you’ll need to wait for it to be processed. The processing time can vary, but it generally takes a few weeks. Some countries offer expedited processing for an additional fee if you need your Seaman’s Book urgently.

Renewing and Using Your Seaman’s Book

A Seaman’s Book is typically valid for five years, after which you will need to renew it. It’s important to keep your Seaman’s Book updated with records of your sea service and ensure that it’s valid whenever you're applying for new cruise ship positions.

You will use your Seaman’s Book to log each period of sea service, recording your role, the ship you worked on, and the duration of your service. This document will be crucial throughout your maritime career, acting as an official record of your experience and qualifications.


Securing a Seaman’s Book is an essential step in landing a cruise ship job. This document not only certifies your sea service but also simplifies many legal and logistical processes when working internationally. Whether you're aiming for a job as a deckhand, engineer, or in hospitality, having a valid Seaman’s Book will make you more competitive in the cruise ship job market and help you sail through the application process.
