Thank you for the welcome Barry.
These old plans appear in the book

It`s fast becoming a collector`s item , and prices for this ( 1973 ) edition range from $ US 53.00 - $ US 244.00.
I do not own a copy , and do not know if a boat has been built to these plans.
Speaking of books , some members here may also be interested in this one , it is on my "to get "list. :

It can be found
http://www.lulu.com/content/1948578I think the boat pictured has potential as a lower cost project , at least the hull construction.
I think a boat around 30 ft length like this may still be affordable .
There seems to be considerable scope for individual customized floor plan and layout.
I have only just begun to research paddle wheelers and would like to find out more , particularly drive train configuration using tractor / truck differentials and gearing.
I have not found much information on this so far.
Thank you again for your interest.
