Frequently Asked Questions
Qualifying sea time typically includes service on commercial vessels, yachts over certain sizes, or naval vessels. The vessel must be engaged in commercial operations or qualifying voyages. Time in port may or may not count depending on the certification requirements.
Sea time requirements vary by certification. For example, OOW deck requires 12 months, Chief Mate requires 18 months as OOW, and Master requires 12 months as Chief Mate. Some certifications allow substitutions or reductions for approved training.
Yacht experience may count towards commercial certifications if the yacht meets minimum size requirements (usually 24m+ or 500GT+) and operates commercially. Private yacht experience typically doesn't count for commercial certificates but may qualify for yacht certifications.
You'll need discharge books, sea service testimonials, or certificates of sea service signed by the master or authorized officer. Documentation should include vessel details, your position, dates of service, and trading areas.
Approved maritime training courses can reduce sea time requirements. For example, completing an approved deck officer cadetship may reduce the required sea time from 36 to 12 months. Training reductions vary by country and certification body.
