Why Do I Need an ENG1 Medical Certificate?

An ENG1 medical certificate declares you as fit and healthy to safely engage in the duties associated with being a Superyacht or ship crew member.

The ENG1 medical examination ensures that the crew member does not have any medical conditions that may jeopardize the safety of other crew members or passengers on board.

Certain medical conditions may be acceptable for specific jobs onboard a vessel and others may not. For example, a colour blind crew member will not be fit for lookout duties on the bridge onboard a superyacht, but may still be fit for duties in other departments. A crew members ENG1 certificate will either state that the crew member is fit with no restrictions, fit with restrictions or unfit for work (Either temporarily or permanently).

ENG1 Medical Examination Procedure

An ENG1 medical typically takes about 30 minutes and it is a quick non-invasive procedure. The process will differ slightly, depending on the patient and the doctor, however, an ENG1 examination will generally include the following:

  • A urine sample (to test for diabetes, kidney functions, blood sugars etc.).
  • General lifestyle questions (drinking and smoking habits, exercise routine etc.).
  • Your blood pressure will be checked.
  • Height and weight will be recorded.
  • A standard eye test.
  • A test for colour blindness.

How Long is an ENG1 Medical Certificate Valid For?

Crew members have to renew their certificate every two years (some every year if they have certain health restrictions). It is important to plan ahead when it comes to booking an appointment for an examination as there are a limited amount of MCA qualified doctors.

You will find ENG1 doctors in Fort Lauderdale, Antibes, the U.K. and other super yachting or maritime hubs around the world, but it is still important to plan ahead, especially with the busy schedules of yacht crew.

Not having the certificate in time could cost you a job - make sure you don't get caught out!

ENG1 Medical Certificate Outcomes and Restrictions

Candidates who do not pass the medical may be disallowed from working at sea, while others may be given restrictions in terms of which duties they can perform. For example, if you do not pass the eye, colour-blindness or hearing test you will not be allowed to perform lookout duties. This will severely restrict your ability to work on deck and will mean that you are unable to become an officer or captain. There are many other medical conditions that will prevent you from working at sea. We recommend that you take the ENG1 medical before attending your STCW or any other courses. This will help prevent you from wasting time and money if you are deemed unfit to work at sea.
