A fascinating link Mick - I can see I'm going to be spending some time there to take it all in...

Just brilliant Ivor, just brilliant. Thank you. It all makes sense to me now.

Yes, this is a must have reference for any model boat enthusiast.

of course this was from 4 years ago and I have read about the model paddlewheel....seems to make sense and is about half of the reason my 'princess elizabeth' has six floats not eight..... the other half of the reason is that I used eight float wheels on the (as yet un-named) tug and saw what I believed to be a practical demonstration of what he says in the article (why he used only five floats!)
