Sailormann is quite correct when talking with the newbie on shore. Once on board though things tend to go to pot in a hurry. It has been my experience that those who have issues with such as bow/stern and port/starboard, etc... soon get into a situation where they cannot communicate and the deficiencies of their lack of language skills becomes hazardous-mostly to themselves. "Watch out for the whimmydiddle" is not of much help when the previous declaration was "jibe-ho" and the newbie has no knowledge of what that arcane term means.
Kind and gentle to the new illiterate sailor, yes. Leave him in such a condition, hell no!
