::Sagamore was built by Doxford in 1893, but the first turret ship had been built the year before (and the year after Wetmore visited Liverpool).  On the relationship between ship types, a drawing of cross-sections would be helpful. I have cross-sections for conventional, turret, and trunk deck ships; I do not have one for a whaleback.  (The upper part is obvious, but the bottom does not show in the photos, and it would also be useful to know if there was a double bottom.)
