There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.
I have indulged in just such conjecture about the design of the ferry boat in use at Cammoge in 1849, crossing the outlet from Poulnasherry Bay, west of Kilrush on the Shannon estuary. The news reports of the time give very little information about the design of the boat, and the reliability of that information is questionable, which makes my speculation even more dangerous. Nonetheless, I thought it might be useful to set out some thoughts on the subject in the hope that other folk, who know more about the background, the location or naval architecture than I do, might be able to help to clarify the design.
