Tumblehome

Inward-sloping sides made it more difficult to board a vessel by force, as the ships would come to contact at their widest points, with the decks some distance apart.

The French Navy in particular promoted the design, advocating it to reduce the weight of the superstructure and increase seaworthiness by creating greater freeboard.

Tsesarevich was delivered to the Russian Imperial Navy in time for it to fight as Admiral Wilgelm Vitgeft's flagship at the Battle of the Yellow Sea on 10 August 1904.

The Russo-Japanese War proved that the tumblehome battleship design was excellent for long-distance navigation, but could be dangerously unstable when watertight integrity was breached.[4][how?]

Unlike rivals, they were not built for conversion in wartime to a warship, and so were cheaper to build and carried more than twice the cargo of a conventional vessel and could be handled by a much smaller crew.

Due to stability concerns, most warships with narrow wave-piercing hulls combine tumblehome with multi-hull designs, such as the Type 022 missile boat.

In 21st century automobile designs this turnunder is less pronounced or eliminated to reduce aerodynamic drag and to help keep the lower portions of the vehicle cleaner under wet conditions.

The house and stable are unique examples and similar to wooden water tower construction with flared supports for added strength.
