Tom, I was being sarcastic. I am annoyed when some poor soul asks a
perfectly innocent question and some A hole answeres with this: "if
you have to ask than yoiu shouldnt *%&$ in the first place. For
example if someone were to ask if a catalina 27 they own is capable of
sailing to the bahamas safely some A hole will say. "well if you have
to ask then you shouldnt be sailing to the bahamas in the first
place!!!!!!!!"

Hey guys... we=B4re all learning. Nobody knows it all and quite frankly,
a newsgroup is a great place to ask questions and get opinions back.
Sometimes you get =B4flamed=B4 and sometimes you get intelligent
information.

And quite frankly, out in the ocean, there=B4s never one answer....

If you have to ask what a bluewater boat is then you have no business
blue water sailing. Sit on the porch. You can't play with the big dogs.
