Pre-screen your health before your ENG-1 or DGS medical examination. Check vision, hearing, BMI, colour vision, and medical history flags against official seafarer fitness standards (ILO/IMO MLC 2006).
These are screening flags. A "Yes" does not automatically disqualify you — the examining doctor makes the final call. Be honest here so you know what to discuss with your doctor.
Many seafarers with borderline conditions get certified fit after proper medical opinion and documentation. SailorGPT can tell you exactly what to tell your doctor, what to declare, and which conditions are genuinely disqualifying vs. manageable.
