(1) The issue of alternative certificates shall not be used in itself to reduce the number of crew on board, to lower the integrity of the profession or “de-skill” seafarers, or to justify the assignment of the combined duties of the engine and deck watchkeeping officers to a single certificate holder during any particular watch.
(2) The person in command shall be designated as the master; and the legal position and authority of the master and others shall not be adversely affected by the implementation of any arrangement for alternative certification. (STCW Reg. VII/3.3)
