      Thank you Mike

      Nothing from Jeremmy, Last time he was in the hospital the only way he had to contact me was from a passing visitor's laptop.

      Hi Pat ,
                    Not sure it is insanity . When I was 9 in 1951 my farther took a teaching job in Oxford, because of
      the housing shortage he bought a old landing craft that had been converted to a house boat. We moored on
      the Thames near to a boat yard that ran steamers on the river. I made friends with the blacksmith named George,
      who made me a metal catapult which got both him and I in trouble with my mother. The yard got a contract making
      steel boats that sold in Canada like hot cakes. They were copies of the traditional canoe made in sheet steel. I bet
      who ever suggested this was thought a bit odd at the time.
               I have sent emails to a section of people that might be of assistance ,the include a couple of Thai boat builders
       plus a couple in USA  and one to Honda marine will let you know any results.
              I hope you have received good news on Jeremmy well being .
       
      Mike

      Thanks Harold
      Heard from him twice in the last 3 weeks, usually email back and forth several times a day. Having typhoid AND malaria in a rural Kenyan hospital is very scary stuff. This is tearing me up because he is SO smart and such a good guy.

      But...at my age I cannot afford to have all my eggs in one basket so I have multiple fallbacks starting up.
      Hi Pat ,
       
      The boat power thing smells of my usual insanity but just think of the possible implications. Only 6% of the boats on lake Victoria are powered yet it is a major source of protein for 30 million people. Long tail boats have not made the transition from Asia, yet with a lathe, welder (one in town) and a way to cast propellers, everything else needed to build them are available there.

      5/8" (about) shaft
      1" water pipe
      pillow blocks or flange bearings (Jeremmy already uses them for grinders, wood lathe and sander)

        What I find interesting is that the long tail does not provide any steering, only propulsion.  This means that if the shaft or guard hits an obstruction, there is little (if any) damage to it.  The rudders (in this case two of them) also will pivot if hit.

        Since Jeremmy will be in an area where damage due to such obstructions might be a severe disadvantage, such a drive system is a huge advantage.  Having a "spring throttle" (i.e. it goes to idle when released) will be a necessity, imagine being in the middle of the lake when an obstruction is hit, no damage to the vessel, but the operator falls overboard.  The boat stops rather than leaving him with a many mile swim to shore.

            As to comparing chalk to cheese with some of these modern ideas about cheese  the chalk is probable more healthier to eat .
