         For someone who claims to own a yacht, you (Busby) don't 
seem to know much about them.  Wind is free.  The yacht is not.  They 
are very expensive to buy and maintain.  One must spend hundreds of 
thousands of dollars to own and maintain a yacht and for what?  To 
get free fuel?  To harness that free fuel one must have sails.  How 
much does a suit of sails cost for a typical yacht?  How long does it 
last?  Come on, Chris.  Wake up for a few minutes.

         It's not that you "know so much," (your self-serving claim 
below) it's that you know so little.  Why don't you do some "study 
and hard work" on the cost per mile of operating your 
yacht.  Remember to include the time spent scraping barnacles off the 
hull.  I suspect you will be in for an unpleasant surprise.
