I spend time in winter on a 30' sail-boat in salt water.  Mast height about
40 ' .Lots of steel rigging and a Ally. . mast.. Can I expect miraculously
low 'ground'  resistance?. I'll just have to sail 3 miles offshore USA
unless 136 licences become more readily available. Why does 'Kite' keep
coming to mind?
