Navigating a career at sea is always an adventure, but before you can set sail, there’s an essential hurdle to clear: the ENG1 medical exam. This mandatory seafarer medical exam is required by the Maritime and Coastguard Agency (MCA) and is designed to ensure you’re medically fit to handle the unique demands and emergencies of working on a sea vessel. However, for many prospective and current seafarers, the ENG1 is surrounded by mystery and fear, thanks to a number of inaccurate rumours.

Does wearing glasses automatically sink your chances of passing the exam? Can a common cold be enough for you to fail? To cut out the noise around seafarer medical exams and relieve any anxieties you may have about attending an ENG1 medical, we are here to bust 5 common myths and show you exactly how to prepare for a seafarer medical with confidence.

Myth 1: “If I Wear Glasses Or Contact Lenses, I’ll Automatically Fail.”

The truth is that wearing corrective lenses does not automatically disqualify you.

The ENG1 medical assesses your vision both with and without correction. The key is that your corrected vision must meet the minimum standard for your role. You’ll be tested for distant and near vision. You must bring your glasses or contact lenses with you to the exam.

The more critical vision assessment for a seafarer medical is colour vision. The test used to determine colour vision is the Ishihara plate test, which presents a series of coloured plates, each containing a number or pattern, hidden within dots of different sizes and hues. If you fail the initial Ishihara plate test, the Approved Doctor (AD) may perform further testing. Failing the colour vision standard may lead to a restriction on your certificate, such as “Not fit for lookout duties at night.”

Myth 2: “The Medical Is Just A Quick Paperwork Exercise.”

The ENG1 is a structured, comprehensive physical examination required by the Maritime and Coastguard Agency (MCA), not just a quick paperwork exercise.

While the medical typically takes around 30 to 45 minutes, it covers a lot more than just paperwork:

The examination begins with a medical history review, which involves a detailed discussion of your past and current health, as well as any medications you take.

This is followed by a physical examination, where the approved doctor will check your height, weight, blood pressure, heart, and lungs.

Essential vision and hearing tests are conducted to assess your acuity, colour vision, and general hearing ability.

You’ll also be required to provide a urine sample, which is tested for glucose to screen for diabetes and to check kidney function.

Finally, a mobility check is performed to assess your musculoskeletal system and reflexes. This can include a hernia check, which is a quick test involving a cough.

The purpose isn’t just to check a box; it’s to ensure you don’t have a medical condition that could be exacerbated at sea or endanger others, where emergency medical care is not readily available.

Myth 3: “Any GP Can Issue An ENG1 Certificate.”

Only doctors approved by the MCA, known as Approved Doctors (ADs), are legally allowed to conduct the ENG1 medical.

These doctors have undergone specific training and are aware of the international standards (like the Maritime Labour Convention or MLC) that govern seafarer fitness. You must ensure the clinic you book with is officially recognised by the MCA. An ENG1 issued by a non-approved doctor is invalid.

Myth 4: “Taking Medication Means I Will Be Deemed Unfit.”

Taking medication is common and in most cases is not a reason for automatic failure.

The key factor is the condition being treated and whether the medication itself could impair your performance or safety at sea. For example, if your medication causes drowsiness, a restriction might be applied.

When preparing for a seafarer’s medical, you should always bring a comprehensive list of all medications you currently take (including dosage and frequency). Be open with the AD about your condition, as they need this information to assess if your health is stable and safe for the sea environment. Understanding common ENG1 medical conditions that lead to failure or restriction is key to preparation. Disqualifying conditions are usually those that pose an unpredictable risk, such as insulin-dependent diabetes or severe, uncontrolled epilepsy.

Myth 5: “If I Fail, My Career Is Over.”

While the possibility of being found temporarily or permanently unfit does exist, there are often pathways available for a career at sea.

The possible outcomes of the ENG1 are:

• Fit for sea service, with no restrictions.
• Fit for sea service, with restrictions (e.g., restricted duties or location).
• Temporarily unfit (requiring re-assessment after a set period, often once a condition is controlled).
• Permanently unfit (if the condition is not reversible).

If you are found temporarily unfit to work at sea, you can work with a specialist to manage your condition and reapply. If you are found permanently unfit and disagree with the decision, you have the right to request an Independent Medical Review for another chance at passing your ENG1.

How To Prepare For A Seafarer Medical Exam

The most important thing you can remember is that ‘preparation is power’. Understanding the requirements and getting any pre-existing conditions checked by your GP before your ENG1 appointment is always the best way to ensure a smooth certification process. With more information, you can take the right steps to make sure you are in the best physical condition for your medical.
