^^^ Correct, most have the side paddles, which aren't much good to ride. I think that there is a sternwheeler operating around some parts of the Murray River though? We used to sit at our camp site on the Darling River (Wentworth) and spot the big girl through a small gap between the 2 rivers - then frantically paddle our lilos across and through the opening to the Murray.

edit - Mannum SA looks like the place to find one of these rides nowadays.
