[ RadSafe ] Rational Thought

My yacht Carefree cost £4500 on ebay 5 years ago.It was built in 1953 and is made of wood: people are afraid of wooden boats nowadays, they want plastic. But I can fix boats and lived on boats for many years on the River Medway, including big boats. At one time I was a registered inshore fisherman (54 Ton vessel MV Renovate) and at another was skipper of a 250 ton coaster (MV Oceanic)  moving ballast. 
I sold Carefree last year for £5000 after recaulking it and various other jobs. 
So it cost me nothing but some paint, caulking cotton, mooring fees. 
And I had a lot of fun.
Get a life Steven. So much time and effort you spend on me. Im flattered, but I wonder what you do for enjoyment?

         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.
