Certainly don't mean to take issue with anyone. I'm in no position to do that!
I look at it this way: Most, that's most
, craft-/business-/hobby-/occupation-/avocation-/whatever-specific words, terms and phases have a purpose. Many, if not most, of them convey a complex or out-of-the-ordinary concept as simply as possible. Forestay, binnacle, starboard, bear off and heave to, for example. I believe learning these terms are important. I believe using them is important. (Just had this discussion with my wife, several days ago, btw.) So, regardless of what my books say: If they're wrong, they're wrong. If what they're calling a "block" is really a "sheave": They're wrong.
Giu, I understand and agree with your point, to a point. Sure, "left wall inside" would probably be understood to mean "port bulkhead below," without problem. But I believe learning the language of a trade enhances our ability with, and enjoyment of it. Looked at another way: Speaking English, I bet I could survive in Portugal without ever learning a word of Portugese. (This is true for a goodly portion of the planet.) But I bet my experience would be much more fulfilling if I did
learn the language--including the nautical bits
sailaway21, I believe this is the 2nd book you've recommended to me this day. Thank you.
