[hpv-boats] re Flex Shaft

[v garza]

This commercial product is not a flex shaft, but is available for those 
inquires looking for a drive system. http://www.prophish.com/pedalboats.html 
It appears to be a rugged (Jose's adventure NY-Rio), somewhat adaptable unit 
with built in steering and easy lift and lower. Don't know the drive ratio, 
but possibly adaptable to a version of Rick's prop which would improve 
efficiency.

Hope this helps.
