Martti Vire has done a great job compiling a site, Wanhat Purjelaivat, with a lot of detail on old ships. He’s got an excellent coverage through history of the development in ships and their technologies. The reason why I am evangelising about the page is that Martti contacted me for some pictures he has on his page. Go to “Historiaa -> Höyryn Aika” to see my photos of a few steam ships.
Great page with a lot of detail, I have to say.
