JohnR, thanks for the comment.
I have a great appreciation for what instructors do. They have a lot of hurdles to overcome. One of them is that often they are given a class of students who have a WIDE variety of experience from never sailed before to regular-sailor-just-trying-to-brush-up. You're comment is right-on, if you have questions ask them but do it at an appropriate time but definitely ask them. Read, sail, learn, read, sail, learn and ask along the way
