What are the physical agility, strength, and flexibility standards?
If you are renewing a Certificate of Registry, Merchant Mariner’s Document (MMD) with Lifeboatman, or MMD without qualified ratings, you are not required to submit a physical examination report (Form CG-719K). However, if you plan to work on seagoing vessels beyond the boundary lines, you will have to submit documentation from a U.S. licensed physician, physician’s assistant, or nurse practitioner certifying that you have the agility, strength, and flexibility to: Climb steep or vertical ladders, Maintain balance on a moving deck, Pull heavy fire hoses up to 400 feet, and have the ability to lift fully charged fire hoses, Rapidly don an exposure suit, Step over door sills of 24 inches in height, and Open or close watertight doors that may weigh up to 56 pounds.
