What Do You Call Lwl, LWL...etc, its benefits, and boat parts

It is totally legitimate to ask anything, without offending anyone, but one has to be prepared, know the "language", to understand the answer. And what some of us want to say is that the OP would need to learn the naval "language" before diving any deeper.
That, in my opinion, is not to be negative, but to steer the OP down the path it should follow.
