If you haven't already discovered this site, be sure to visit & join [link=http://www.paddleducks.co.uk/]Paddleducks[/link]. You & your father will learn a lot from these experienced paddlewheel fans who mostly hail from the UK & Australia. Their mission statement says it all:
Paddleducks was setup to help with the unique problems encountered when building a paddlewheel driven ship, with particular emphasis on models. We are a group of people with one thing in common, a PASSION for paddlers!
Our aim is to provide modellers with one of the most comprehensive sources of imformation and research material on every type of paddle driven vessel - Sternwheel or sidewheel, and boats from all corners of the globe.
So if you have an interest in modelling these unique vessels, either as a static exhibit, a fully working radio controlled model, or even a full sized vessel capable of carrying people, this is THE place to be!
