DNS Sponsorship Medical Requirements
Medical fitness is one of the primary criteria for aspiring students who are interested in joining the DNS program and pursuing a career in the Merchant Navy.
Passing the DNS sponsorship examination or interview process will not alone enable the candidate to be medically fit to join any vessel; the candidate should be medically fit according to the relevant criteria of seafarers.
This is especially true for DNS candidates who join the deck department, as the deck department work entails navigation, watchkeeping, lookouts, deck work, and other activities that are performed under varying sea and weather conditions.
The relevant medical test must be conducted as per the criteria laid down by the Directorate General of Shipping (DGS).
What Is a DNS Sponsorship Medical Examination?
A sponsorship medical examination is conducted to determine whether a candidate is medically fit to pursue a seafaring career.
For a pre-sea candidate, the examination assesses whether the person can safely perform the physical and visual duties associated with the intended position on board.
The DGS medical rules require the examiner to consider factors such as the following:
- Medical history
- Physical fitness
- Height and weight
- Pulse and blood pressure
- Hearing
- Eyesight
- Color vision
- Laboratory investigations
- Other medical conditions that may affect fitness for service at sea
The examination can also take into account the intended position on board and the physical demands associated with that position.
Who Conducts the DNS Medical Examination?
The examination must be taken by candidates via a DGS-approved medical examiner in accordance with the applicable maritime medical regulations.
An ordinary medical certificate from a general practitioner or a routine medical check-up is not considered the necessary seafarer’s medical examination.
DGS has requirements for DGS-approved medical examiners and the format for relevant medical certificates. Students are advised to look up the requirements of DGS-approved medical examiners before taking an examination.
DNS Medical Requirements for the Deck Department
DNS candidates are preparing for the nautical or deck department, so the applicable deck-side standards are particularly relevant.
The current DGS medical rules require assessment of:
- General physical fitness
- Hearing
- Distance vision
- Near vision
- Color vision
- Visual fields
- Night vision
- Other conditions affecting safe performance of duties
The medical examiner determines fitness using the standards applicable to the candidate’s intended position.
Eyesight Requirements for DNS
Eyesight forms an important medical requirement for DNS candidates.
According to the DGS pre-sea eyesight requirements for the nautical department, the following apply:
- Distance eyesight without aid: 1.0 (6/6) in the better eye
- Distance eyesight without aid: 0.67 (6/9) in the other eye
- Normal color vision
- Color vision is determined through the Ishihara test card
These medical requirements are explicitly stated for the nautical/deck department.
Students are advised not to confuse the medical eye requirements for the engine department or any other maritime occupation with those of DNS. The candidates are expected to carry out deck operations; hence, the relevant eyesight requirements for the nautical department have to be verified.
Is Spectacle Use Allowed for DNS?
The candidate must not assume that being nearsighted automatically disqualifies them medically.
The relevant standard will vary based on the eyesight standard for the nautical department before sailing. For the deck candidate, the DGS pre-sea standard is the standard of unaided distant vision.
Since the eyesight standard can determine admission to the DNS, those students who have been wearing glasses or have had some sort of eye treatment done should undergo the test by the approved DGS medical examiner.

Color Vision Requirement for DNS
For one to join the nautical department, normal color vision is mandatory.
According to the pre-sea standard by DGS, it is a requirement that normal color vision should be proven by means of the Ishihara test chart.
Color vision is important when it comes to navigation and safety out at sea, especially recognizing navigation lights, among others. An applicant should not depend on an online color vision test for eligibility.
Hearing Requirements
Hearing is also assessed during the seafarer medical examination. The DGS medical rules specifically require the candidate’s hearing, eyesight, and color vision to be assessed according to the prescribed standards.
Good hearing is important on board because seafarers need to communicate effectively and respond to alarms, instructions, and other audible signals.
General Physical Fitness
A DNS candidate should be physically fit enough to perform normal duties on board a ship.
The medical examination can include measurements and assessments such as the following:
- Height
- Weight
- Pulse rate
- Blood pressure
- Medical history
- Physical examination
- Laboratory tests
- Hearing assessment
- Vision assessment
The medical examiner may request additional investigations when necessary to determine fitness.
The purpose is not simply to check whether someone is generally healthy. The assessment is focused on whether the candidate can safely perform the duties associated with a seafaring career.
Medical Conditions and DNS Sponsorship
Having a health problem does not necessarily mean that each of these candidates will automatically fail.
The medical examination looks into whether a certain health problem
- Impacts the individual’s ability to carry out tasks safely
- Worsens during the period of service on board
- Is a safety concern
- Necessitates medication that is not always easily accessible on board
- Impacts other individuals on board
The DGS medical regulations dictate that the medical examiner should consider any medical background pertinent to fitness for service on board.
This final judgment should come from the authorized medical examiner and not any assumptions made from information available online.
Medical History and Previous Treatment
Candidates should provide accurate information about their medical history.
The DGS medical examination process includes a medical-history assessment, and candidates are required to provide the relevant information requested during the examination.
This can include information about:
- Previous illnesses
- Injuries
- Surgeries
- Ongoing treatment
- Previous medical conditions
- Relevant medications
Students should not hide medical information from the examiner. Providing incomplete or false information can create problems later during medical verification or employment.
What Tests Are Included in the DNS Medical Examination?
The exact tests can vary according to the candidate and the examiner’s professional assessment.
The DGS rules provide for assessment of areas including the following:
- Physical measurements
- Blood pressure
- Medical history
- Hearing
- Eyesight
- Color vision
- Laboratory investigations
- Other examinations considered necessary
The medical examiner can request additional tests when required to determine whether the candidate meets the applicable fitness standards.
Is a Medical Certificate Required for DNS Sponsorship?
Shipping organizations have the option of asking for a candidate’s medical fitness certificate at the time of their sponsorship process.
This may vary according to the organization. For instance, an organization may ask for a medical certificate prior to selection, after selection, or prior to attending the training institute.
A candidate is supposed to follow the instructions that have been provided by the sponsoring organization for the medical fitness test.
DNS Sponsorship: Medical vs College Medical
Students must know that there can be more than one medical-related condition that must be met during the admission process.
The sponsor company may require medical evidence in the recruitment process of the candidates, but at the same time, the maritime institute may require medical pre-sea conditions to be met by the candidates. The best way out is to get the medical test done on the basis of the criteria set by DGS and the sponsoring company.
Can a Candidate Be Rejected After Clearing the Sponsorship Exam?
Yes. The written test and interview determine whether a person is suitable for the company’s admission process. The medical condition of the applicant is something different.
An individual who performs well during the written test and interview may fail to continue due to the lack of required medical standards.
That is why students need to check whether they have appropriate medical conditions from the beginning of the admission process.
What Can Make a Candidate Medically Unfit?
There is no single short list that applies to every possible medical situation.
A candidate can be found unfit if a condition or limitation prevents the person from meeting the prescribed standards for the intended seafaring position.
For DNS candidates, particular attention is given to:
- Required eyesight
- Color vision
- Hearing
- Physical fitness
- Conditions that may affect safe work at sea
The medical examiner makes the assessment using the applicable DGS standards.
Can Medical Fitness Standards Change?
Yes. Changes to maritime medical requirements can be made via updated regulations, notice, and guidelines. The students must not rely on an outdated eligibility article or medical requirement that is taken from any earlier admission period.
Medical examination requirements for the DGS have been updated by the DGS and include requirements relating to pre-sea medical tests, hearing tests, eyesight tests, and color-vision tests.
This is the reason why candidates need to make sure about their DGS medical requirements for their particular admission group.
Medical Fitness and Sponsorship Companies
There may be other requirements set by different shipping firms, but the individual must also meet the relevant legal medical requirements for sailing.
The shipping firm may ask for a medical report in its sponsorship process, giving specific guidance on where and when the process should take place.
One should not think that meeting the medical requirement for one shipping firm means he will automatically qualify with another firm.
When Should You Get the DNS Medical Examination?
Getting medically assessed before committing to the course is a sensible approach, particularly for candidates who are unsure about their eyesight, color vision, hearing, or another medical requirement.
A medical assessment can help identify potential issues before the student spends money on the following:
- Sponsorship applications
- Coaching
- Travel
- College applications
- Course fees
The official DGS-approved medical process remains the relevant standard for determining fitness.

Final Thoughts
Medical fitness is not a formality in the admission process of the DNS. Medical fitness is a basic requirement to get admitted into a field where fitness, good vision in both eyes, color vision, hearing capability, and safety at sea are important criteria.
In case of DNS applicants joining as deck cadets, the DGS pre-sea standard requires 6/6 distant vision in the better eye and 6/9 in the other eye without any corrective glasses, along with normal color vision based on the Ishihara color test chart.
The medical fitness test will cover hearing ability, overall physical fitness, medical history, etc. that will affect safe service at sea.
Students are supposed to get themselves examined by the authorized medical practitioner as per the requirements for their specific admission and sponsorship batches.
Most importantly, students should not take medical fitness suggestions from unofficial sources or old eyesight charts while considering their eligibility for DNS.
