Nautically, I would say you have missed nothing captain as it would be your job to make sure the tillerman knows the difference between starboard and garboard as the course the Admiral has ordered would need to be rigidly adhered to, as going aground would be futile given that there might be reefs and/or currents that need to be avoided for safe passage; in which case the tillerman needs to be TRUSTED, only saying Sir.
