Under the MLC, 2006 and STCW, your medical certificate confirms that you are medically fit to perform the duties you will carry out at sea. Formats differ by country, but the content is broadly similar.
What it usually states
- Your identity and the examiner’s details and authorization
- Whether hearing and eyesight (including colour vision where relevant) meet the required standards
- Whether you are fit for lookout duties, where relevant
- Whether you are free from conditions likely to be aggravated by sea service or to endanger others
- Any limitations or restrictions
- Date of examination and expiry date
Limitations and restrictions
A certificate can be issued with limitations — for example on duties, sea areas or the need to wear correction. Make sure you understand them and that your employer is aware.
Validity
International maximums are two years (one year under 18), and six years for colour-vision certification. Your authority may set shorter periods. See medical certificate validity.
Keep track
Use the certificate tracker to record your expiry date and get reminders.
