  1. Thank you for the insightful information on the various ship curves. I have a set of Lyman Radius curves Although they are not ship curves, I know they are highway curves and they are quite a few for sale on line.... I have searched the web, and the US patent office and have found nothing about their origin nor who designed them...let alone how one actually used them... I was hoping someone on this site might be able to tell me a bit more about them. Any information would be most welcome...here is set similar to mine on worthpoint... https://www.worthpoint.com/worthopedia/vintage-engineering-lyman-radius-
