Tex I am an engineer with over thirty five years 

Tex I am an engineer with over thirty five years experience in aerospace and military hardware development and management.  My brother worked for NASA until just recently, and I have another who is a math wiz who wrote software for the first lunar orbit and I could go on and on.  I respect your views, but let me put this to you very very gently.  You do not know what you are talking about.  You say the sharc looks nice.  WOW!  That is brilliant engineering jargon.  You say the TigerLynk will be off balance.  Really.  Yet you think a backhoe mounted on a barge is the grandest design the world has ever seen.  Give me a break.  What did you say you did for a living?  What degree qualifies you to make such ridiculous declarations?  If this technology (designed by the same man who designed the CanadArm used on the space shuttle) was not already proven in the harshest conditions imaginable, then some might actually think you made sense.  But the technology was proved out and is working even today on the International Space Station.  Not to mention the fact that the prototype TigerLynk harvested a million board feet of lumber without issue in Brazil.  The same lumber was then used for Atlantic City's famed Board Walk, so you can see it and feel it if you want to.  The company likely to build the TigerLynk is world renown for this kind of manufacturing, and marine engineering is its forte.

So I have said enough.
