A construction model of a ship-of-the-line that shows many of Seppings’ innovations: Seppings blocks and shoring beneath, diagonal bracing in the upper level of the bow, and a rounded bow and stern.
Innovation in design soon made Hotchkiss and Driggs-Schroeder guns obsolete for first-line warships. The weapons were relegated to service with patrol boats and small craft. An example can be seen here at the bow of the tug USS Tacoma in 1898.
The sloop-of-war Austin, flagship of the Second Texas Navy from 1840 to 1846, at sea. The ship appears to be experiencing Force 4 or 5 conditions—a “moderate” or “fresh” breeze—on the modern Beaufort Scale.
A drawing of an early Barr and Stroud rangefinder that shows the device’s principal components. The paired eyepieces are near the top in the center.
A long 12-pounder cannon on board the replica French frigate l’Hermione. Note the wheels that make traversing the barrel difficult.
