Hey,
There is a link to the official website of Elias Lonnrot, built in the 1980's with diesel propulsion and independant paddle drive, so i've read.
http://www.eliaksenristeilyt.fi/The ship is Finnish, and the website is in Finnish too and doesnt seem to have an english version.
Maybe you speak finnish or are patient with a translator?!
Just thought you might like to see it in case you hadnt already....
Regards, Andrew
