RMI-ENG-L2.1

The single highest rated engine rule

RMI-ENG-M2 · Propulsion power and limitations · RMI-ENG-M2-A The single highest rated engine rule, reading CoC limitations against the MSMC, and how the manning document is built.

Independent study. xplor is not affiliated with the Republic of the Marshall Islands Maritime Administrator and awards no certificate, endorsement or Certificate of Competency. Whether a particular engineer CoC is endorsed, and at what capacity and limitation, is decided only by the Administrator on application through an authorised filing agent, and the yacht's own MSMC is the final word on what it must carry.
